Weblate basics

Project and component structure

In Weblate translations are organized into projects and components. Each project can contain number of components and those contain translations into individual languages. The component corresponds to one translatable file (for example GNU gettext or Android string resources). The projects are there to help you organize component into logical sets (for example to group all translations used within one application).

Internally, each project has translations to common strings propagated across other components within it by default. This lightens the burden of repetitive and multi version translation. The translation propagation can be disabled per Component configuration using Allow translation propagation in case the translations should diverge.

Registration and user profile

Registration

Everybody can browse projects, view translations or suggest translations by default. Only registered users are allowed to actually save changes, and are credited for every translation made.

You can register by following a few simple steps:

Fill out the registration form with your credentials.
Activate registration by following the link in the e-mail you receive.
Optionally adjust your profile to choose which languages you know.

Dashboard

When you sign in, you will see an overview of projects and components, as well as their respective translation progression.

New in version 2.5.

Components of projects you are watching are shown by default, and cross-referenced with your preferred languages.

Hint

You can switch to different views using the navigation tabs.

The menu has these options:

Projects > Browse all projects in the main menu showing translation status for each project on the Weblate instance.
Selecting a language in the main menu Languages will show translation status of all projects, filtered by one of your primary languages.
Watched translations in the Dashboard will show translation status of only those projects you are watching, filtered by your primary languages.

In addition, the drop-down can also show any number of component lists, sets of project components preconfigured by the Weblate administrator, see Component Lists.

You can configure your personal default dashboard view in the Preferences section of your user profile settings.

Note

When Weblate is configured for a single project using SINGLE_PROJECT in the settings.py file (see Configuration), the dashboard will not be shown, as the user will be redirected to a single project or component instead.

User profile

The user profile is accessible by clicking your user icon in the top-right of the top menu, then the Settings menu.

The user profile contains your preferences. Name and e-mail address is used in VCS commits, so keep this info accurate.

Note

All language selections only offer currently translated languages.

Hint

Request or add other languages you want to translate by clicking the button to make them available too.

Languages

Interface language

Choose the language you want to display the UI in.

Translated languages

Choose which languages you prefer to translate, and they will be offered on the main page of watched projects, so that you have easier access to these all translations in each of those languages.

Secondary languages

You can define which secondary languages are shown to you as a guide while translating. An example can be seen in the following image, where the Hebrew language is shown as secondarily:

Preferences

Default dashboard view

On the Preferences tab, you can pick which of the available dashboard views to present by default. If you pick the Component list, you have to select which component list will be displayed from the Default component list drop-down.

Component Lists

Editor link

A source code link is shown in the web-browser configured in the Component configuration by default.

Hint

By setting the Editor link, you use your local editor to open the VCS source code file of translated strings. You can use Template markup.

Usually something like editor://open/?file={{filename}}&line={{line}} is a good option.

See also

You can find more info on registering custom URL protocols for the editor in the Nette documentation.

Notifications

Subscribe to various notifications from the Notifications tab. Notifications for selected events on watched or administered projects will be sent to you per e-mail.

Some of the notifications are sent only for events in your languages (for example about new strings to translate), while some trigger at component level (for example merge errors). These two groups of notifications are visually separated in the settings.

You can toggle notifications for watched projects and administered projects and it can be further tweaked (or muted) per project and component. Visit the component overview page and select appropriate choice from the Watching menu.

In case Automatically watch projects on contribution is enabled you will automatically start watching projects upon translating a string. The default value depends on DEFAULT_AUTO_WATCH.

Note

You will not receive notifications for your own actions.

Account

The Account tab lets you set up basic account details, connect various services you can use to sign in into Weblate, completely remove your account, or download your user data (see Weblate user data export).

Note

The list of services depends on your Weblate configuration, but can be made to include popular sites such as GitLab, GitHub, Google, Facebook, or Bitbucket or other OAuth 2.0 providers.

Profile

All of the fields on this page are optional and can be deleted at any time, and by filling them out, you’re giving us consent to share this data wherever your user profile appears.

Avatar can be shown for each user (depending on ENABLE_AVATARS). These images are obtained using https://gravatar.com/.

Licenses

API access

You can get or reset your API access token here.

Audit log

Audit log keeps track of the actions performed with your account. It logs IP address and browser for every important action with your account. The critical actions also trigger a notification to a primary e-mail address.

Running behind reverse proxy

Translating using Weblate

Thank you for interest in translating using Weblate. Projects can either be set up for direct translation, or by way of accepting suggestions made by users without accounts.

Overall, there are two modes of translation:

The project accepts direct translations
The project only accepts suggestions, which are automatically validated once a defined number of votes is reached

Please see Translation workflows for more info on translation workflow.

Options for translation project visibility:

Publicly visible and anybody can contribute
Visible only to a certain group of translators

See also

Access control, Translation workflows

Translation projects

Translation projects hold related components; resources for the same software, book, or project.

Translation links

Having navigated to a component, a set of links lead to its actual translation. The translation is further divided into individual checks, like Not translated strings or Strings needing action. If the whole project is translated, without error, All strings is still available. Alternatively you can use the search field to find a specific string or term.

Suggestions

Note

Actual permissions might vary depending on your Weblate configuration.

Anonymous users can only (by default) forward suggestions. Doing so is still available to signed-in users, in cases where uncertainty about the translation arises, prompting other translators to review it.

The suggestions are scanned on a daily basis to remove duplicates and suggestions matching the current translation.

Comments

Three types of comments can be posted: for translations, source strings, or to report source string bugs when this functionality is turned on using Enable source reviews. Choose the one suitable to topic you want to discuss. Source string comments are in any event good for providing feedback on the original string, for example that it should be rephrased or to ask questions about it.

You can use Markdown syntax in all comments and mention other users using @mention.

Variants

Variants are used to group different length variants of the string. The frontend of your project can then use different strings depending on the screen or window size.

See also

String variants, Variants

Labels

Labels are used to categorize strings within a project to further customize the localization workflow (for example to define categories of strings).

Following labels are used by Weblate:

Automatically translated: String was translated using Automatic translation.
Source needs review: String was marked for review using Source strings reviews.

See also

String labels

Translating

On the translation page, the source string and an editing area for its translation are shown. Should the translation be plural, multiple source strings and editing areas are shown, each described and labeled in the amount of plural forms the translated language has.

All special whitespace characters are underlined in red and indicated with grey symbols. More than one subsequent space is also underlined in red to alert the translator to a potential formatting issue.

Various bits of extra info can be shown on this page, most of which coming from the project source code (like context, comments or where the message is being used). Translation fields for any secondary languages translators select in the preferences will be shown (see Secondary languages) above the source string.

Below the translation, translators will find suggestion made by others, to be accepted (✓), accepted with changes (✏️), or deleted (🗑).

Plurals

Words changing form to account of their numeric designation are called plurals. Each language has its own definition of plurals. English, for example, supports one. In the singular definition of for example “car”, implicitly one car is referenced, in the plural definition, “cars” two or more cars are referenced (or the concept of cars as a noun). Languages like for example Czech or Arabic have more plurals and also their rules for plurals are different.

Weblate has full support for each of these forms, in each respective language (by translating every plural separately). The number of fields and how it is in turn used in the translated application or project depends on the configured plural formula. Weblate shows the basic info, and the Language Plural Rules by the Unicode Consortium is a more detailed description.

Plural formula

Keyboard shortcuts

Changed in version 2.18: The keyboard shortcuts have been revamped in 2.18 to less likely collide with browser or system defaults.

The following keyboard shortcuts can be utilized during translation:

Keyboard shortcut	Description
`Alt+Home`	Navigate to first translation in current search.
`Alt+End`	Navigate to last translation in current search.
`Alt+PageUp` or `Ctrl ↑` or `Alt ↑` or `Cmd ↑`	Navigate to previous translation in current search.
`Alt+PageDown` or `Ctrl+↓` or `Alt+↓` or `Cmd+↓`	Navigate to next translation in current search.
`Alt+Enter` or `Ctrl+Enter` or `Cmd+Enter`	Save current translation.
`Ctrl+Shift+Enter` or `Cmd+Shift+Enter`	Unmark translation as needing edit and submit it.
`Ctrl+E` or `Cmd+E`	Focus translation editor.
`Ctrl+U` or `Cmd+U`	Focus comment editor.
`Ctrl+M` or `Cmd+M`	Shows Automatic suggestions tab, see Automatic suggestions.
`Ctrl+1` to `Ctrl+9` or `Cmd+1` to `Cmd+9`	Copies placeable of given number from source string.
`Ctrl+M`+`1` to `9` or `Cmd+M`+`1` to `9`	Copy the machine translation of given number to current translation.
`Ctrl+I`+`1` to `9` or `Cmd+I`+`1` to `9`	Ignore one item in the list of failing checks.
`Ctrl+J` or `Cmd+J`	Shows the Nearby strings tab.
`Ctrl+S` or `Cmd+S`	Focus search field.
`Ctrl+O` or `Cmd+O`	Copy source string.
`Ctrl+Y` or `Cmd+Y`	Toggle the Needs editing flag.

Visual keyboard

A small visual keyboard row is shown just above the translation field. This can be useful to keep local punctuation in mind (as the row is local to each language), or have characters otherwise hard to type handy.

The shown symbols factor into three categories:

User configured characters defined in the User profile
Per-language characters provided by Weblate (e.g. quotes or RTL specific characters)
Characters configured using SPECIAL_CHARS

Translation context

This contextual description provides related info about the current string.

String attributes: Things like message ID, context (msgctxt) or location in source code.
Screenshots: Screenshots can be uploaded to Weblate to better inform translators of where and how the string is used, see Visual context for strings.
Nearby strings: Displays neighbouring messages from the translation file. These are usually also used in a similar context and prove useful in keeping the translation consistent.
Other occurrences: In case a message appears in multiple places (e.g. multiple components), this tab shows all of them if they are found to be inconsistent (see Inconsistent). You can choose which one to use.
Translation memory: Look at similar strings translated in past, see Translation Memory.
Glossary: Displays terms from the project glossary used in the current message.
Recent changes: List of people whom have changed this message recently using Weblate.
Project: Project info like instructions for translators, or a directory or link to the string in the version control system repository the project uses.

If you want direct links, the translation format has to support it.

Translation history

Every change is by default (unless turned off in component settings) saved in the database, and can be reverted. Optionally one can still also revert anything in the underlying version control system.

Translated string length

Weblate can limit the length of a translation in several ways to ensure the translated string is not too long:

The default limitation for translation is ten times longer than the source string. This can be turned off by LIMIT_TRANSLATION_LENGTH_BY_SOURCE_LENGTH. In case you are hitting this, it might be also caused by a monolingual translation erroneously set up as bilingual one, making Weblate mistaking the translation key for the actual source string. See Bilingual and monolingual formats for more info.
Maximal length in characters defined by translation file or flag, see Maximum length of translation.
Maximal rendered size in pixels defined by flags, see Maximum size of translation.

Automatic suggestions

Based on configuration and your translated language, Weblate provides suggestions from several machine translation tools and Translation Memory. All machine translations are available in a single tab of each translation page.

See also

You can find the list of supported tools in Machine translation.

Automatic translation

You can use automatic translation to bootstrap translation based on external sources. This tool is called Automatic translation accessible in the Tools menu, once you have selected a component and a language:

Two modes of operation are possible:

Using other Weblate components as a source for translations.
Using selected machine translation services with translations above a certain quality threshold.

You can also choose which strings are to be auto-translated.

Warning

Be mindful that this will overwrite existing translations if employed with wide filters such as All strings.

Useful in several situations like consolidating translation between different components (for example the application and its website) or when bootstrapping a translation for a new component using existing translations (translation memory).

The automatically translated strings are labelled by Automatically translated.

Rate limiting

To avoid abuse of the interface, rate limiting is applied to several operations like searching, sending contact forms or translating. If affected by it, you are blocked for a certain period until you can perform the operation again.

Default limits and fine-tuning is described in the administrative manual, see Rate limiting.

Search and replace

Change terminology effectively or perform bulk fixing of the strings using Search and replace in the Tools menu.

Hint

Don’t worry about messing up the strings. This is a two-step process showing a preview of edited strings before the actual change is confirmed.

Bulk edit

Bulk editing allows performing one operation on number of strings. You define strings by searching for them and set up something to be done for matching ones. The following operations are supported:

Changing string state (for example to approve all unreviewed strings).
Adjust translation flags (see Customizing behavior using flags)
Adjust string labels (see String labels)

Hint

This tool is called Bulk edit accessible in the Tools menu of each project, component or translation.

See also

Bulk edit addon

Matrix View

To compare different languages efficiently you can use the matrix view. It is available on every component page under the Tools menu. First select all languages you want to compare and confirm your selection, after that you can click on any translation to open and edit it quickly.

The matrix view is also a very good starting point to find missing translations in different languages and quickly add them from one view.

Zen Mode

The Zen editor can be enabled by clicking the Zen button on the top right while translating a component. It simplifies the layout and removes additional UI elements such as Nearby strings or the Glossary.

You can select the Zen editor as your default editor using the Preferences tab on your User profile. Here you can also choose between having translations listed Top to bottom or Side by side depending on your personal preference.

Downloading and uploading translations

You can export files from a translation, make changes, and import them again. This allows working offline, and then merging changes back into the existing translation. This works even if it has been changed in the meantime.

Note

Available options might be limited by access control settings.

Downloading translations

From the project or component dashboard, translatable files can be downloaded in the Files menu.

The first option is to download the file in the original format as it is stored in the repository. In this case, any pending changes in the translation are getting committed and the up-to-date file is yield without any conversions.

You can also download the translation converted into one of the widely used localization formats. The converted files will be enriched with data provided in Weblate; such as additional context, comments or flags. Several file formats are available via the Files ↓ Customize download menu:

gettext PO
XLIFF with gettext extensions
XLIFF 1.1
TermBase eXchange
Translation Memory eXchange
gettext MO (only available when translation is using gettext PO)
CSV
Excel Open XML
JSON (only available for monolingual translations)
Android String Resource (only available for monolingual translations)
iOS strings (only available for monolingual translations)

Hint

The content available in the converted files differs based on file format features, you can find overview in Translation types capabilities.

Uploading translations

When you have made your changes, use Upload translation in the Files menu.

Supported file formats

Any file in a supported file format can be uploaded, but it is still recommended to use the same file format as the one used for translation, otherwise some features might not be translated properly.

See also

Supported file formats

The uploaded file is merged to update the translation, overwriting existing entries by default (this can be turned off or on in the upload dialog).

Import methods

These are the choices presented when uploading translation files:

Add as translation (translate)

Imported translations are added as translations. This is the most common usecase, and the default behavior.

Only translations are used from the uploaded file and no additional content.

Add as suggestion (suggest)

Imported translations are added as suggestions, do this when you want to have your uploaded strings reviewed.

Only translations are used from the uploaded file and no additional content.

Add as translation needing edit (fuzzy)

Imported translations are added as translations needing edit. This can be useful when you want translations to be used, but also reviewed.

Only translations are used from the uploaded file and no additional content.

Replace existing translation file (replace)

Existing file is replaced with new content. This can lead to loss of existing translations, use with caution.

Update source strings (source)

Updates source strings in bilingual translation file. This is similar to what Update PO files to match POT (msgmerge) does.

This option is supported only for some file formats.

Add new strings (add)

Adds new strings to the translation. It skips the one which already exist.

In case you want to both add new strings and update existing translations, upload the file second time with Add as translation.

This option is available only with Manage strings turned on.

Only source, translation and key (context) are used from the uploaded file.

Conflicts handling

Defines how to deal with uploaded strings which are already translated.

Strings needing edit

There is also an option for how to handle strings needing edit in the imported file. Such strings can be handle in one of the three following ways: “Do not import”, “Import as string needing edit”, or “Import as translated”.

Overriding authorship

With admin permissions, you can also specify authorship of uploaded file. This can be useful in case you’ve received the file in another way and want to merge it into existing translations while properly crediting the actual author.

Glossary

Each project can include one or more glossaries as a shorthand for storing terminology. Glossary easify maintaining consistency of the translation.

A glossary for each language can be managed on its own, but they are stored together as a single component which helps project admins and multilingual translators to maintain some cross-language consistency as well. Terms from the glossary containing words from the currently translated string are displayed in the sidebar of the translation editor.

Managing glossaries

Changed in version 4.5: Glossaries are now regular translation components and you can use all Weblate features on them — commenting, storing in a remote repository, or adding explanations.

Use any component as a glossary by turning on Use as a glossary. You can create multiple glossaries for one project.

An empty glossary for a given project is automatically created with the project. Glossaries are shared among all components of the same project, and optionally with other projects using Share in projects from the respective glossary component.

The glossary component looks like any other component in Weblate with added colored label:

You can browse all glossary terms:

or edit them as any translations.

Glossary terms

Glossary terms are translated the same way regular strings are. You can toggle additional features using the Tools menu for each term.

Untranslatable terms

New in version 4.5.

Flagging certain glossary term translations read-only by bulk-editing, typing in the flag, or by using Tools ↓ Mark as read-only means they can not be translated. Use this for brand names or other terms that should not be changed in other languages. Such terms are visually highlighted in the glossary sidebar.

See also

Customizing behavior using flags

Forbidden translations

New in version 4.5.

Flagging certain glossary term translations as forbidden, by bulk-editing, typing in the flag, or by using Tools ↓ Mark as forbidden translation means they are not to be used. Use this to clarify translation when some words are ambiguous or could have unexpected meanings.

See also

Customizing behavior using flags

Terminology

New in version 4.5.

Flagging certain glossary terms as terminology by bulk-editing, typing in the flag, or by using Tools ↓ Mark as terminology adds entries for them to all languages in the glossary. Use this for important terms that should be well thought out, and retain a consistent meaning across all languages.

See also

Customizing behavior using flags

Variants

Variants are a generic way to group strings together. All term variants are listed in the glossary sidebar when translating.

Hint

You can use this to add abbreviations or shorter expressions for a term.

See also

String variants

Checks and fixups

The quality checks help catch common translator errors, ensuring the translation is in good shape. The checks can be ignored in case of false positives.

Once submitting a translation with a failing check, this is immediately shown to the user:

Automatic fixups

In addition to Quality checks, Weblate can fix some common errors in translated strings automatically. Use it with caution to not have it add errors.

See also

AUTOFIX_LIST

Quality checks

Weblate employs a wide range of quality checks on strings. The following section describes them all in further detail. There are also language specific checks. Please file a bug if anything is reported in error.

Translation checks

Executed upon every translation change, helping translators maintain good quality translations.

BBcode markup

Summary: BBcode in translation does not match source
Scope: translated strings
Check class: weblate.checks.markup.BBCodeCheck
Flag to ignore: ignore-bbcode

BBCode represents simple markup, like for example highlighting important parts of a message in bold font, or italics.

This check ensures they are also found in translation.

Note

The method for detecting BBcode is currently quite simple so this check might produce false positives.

Consecutive duplicated words

New in version 4.1.

Summary: Text contains the same word twice in a row:
Scope: translated strings
Check class: weblate.checks.duplicate.DuplicateCheck
Flag to ignore: ignore-duplicate

Checks that no consecutive duplicate words occur in a translation. This usually indicates a mistake in the translation.

Hint

This check includes language specific rules to avoid false positives. In case it triggers falsely in your case, let us know. See Reporting issues in Weblate.

Does not follow glossary

New in version 4.5.

Summary: The translation does not follow terms defined in a glossary.
Scope: translated strings
Check class: weblate.checks.glossary.GlossaryCheck
Flag to enable: check-glossary
Flag to ignore: ignore-check-glossary

This check has to be turned on using check-glossary flag (see Customizing behavior using flags). Please consider following prior to enabling it:

It does exact string matching, the glossary is expected to contain terms in all variants.
Checking each string against glossary is expensive, it will slow down any operation in Weblate which involves running checks like importing strings or translating.

Double space

Summary: Translation contains double space
Scope: translated strings
Check class: weblate.checks.chars.DoubleSpaceCheck
Flag to ignore: ignore-double-space

Checks that double space is present in translation to avoid false positives on other space-related checks.

Check is false when double space is found in source meaning double space is intentional.

Formatted strings

Checks that formatting in strings are replicated between both source and translation. Omitting format strings in translation usually causes severe problems, so the formatting in strings should usually match the source.

Weblate supports checking format strings in several languages. The check is not enabled automatically, only if a string is flagged appropriately (e.g. c-format for C format). Gettext adds this automatically, but you will probably have to add it manually for other file formats or if your PO files are not generated by xgettext.

This can be done per unit (see Additional info on source strings) or in Component configuration. Having it defined per component is simpler, but can lead to false positives in case the string is not interpreted as a formatting string, but format string syntax happens to be used.

Hint

In case specific format check is not available in Weblate, you can use generic Placeholders.

Besides checking, this will also highlight the formatting strings to easily insert them into translated strings:

AngularJS interpolation string

Summary: AngularJS interpolation strings do not match source
Scope: translated strings
Check class: weblate.checks.angularjs.AngularJSInterpolationCheck
Flag to enable: angularjs-format
Flag to ignore: ignore-angularjs-format
Named format string example: Your balance is {{amount}} {{ currency }}

C format

Summary: C format string does not match source
Scope: translated strings
Check class: weblate.checks.format.CFormatCheck
Flag to enable: c-format
Flag to ignore: ignore-c-format
Simple format string example: There are %d apples
Position format string example: Your balance is %1$d %2$s

C# format

Summary: C# format string does not match source
Scope: translated strings
Check class: weblate.checks.format.CSharpFormatCheck
Flag to enable: c-sharp-format
Flag to ignore: ignore-c-sharp-format
Position format string example: There are {0} apples

See also

Formatted strings, C# String Format

ECMAScript template literals

Summary: ECMAScript template literals do not match source
Scope: translated strings
Check class: weblate.checks.format.ESTemplateLiteralsCheck
Flag to enable: es-format
Flag to ignore: ignore-es-format
Interpolation example: There are ${number} apples

See also

Formatted strings, Template literals

i18next interpolation

New in version 4.0.

Summary: The i18next interpolation does not match source
Scope: translated strings
Check class: weblate.checks.format.I18NextInterpolationCheck
Flag to enable: i18next-interpolation
Flag to ignore: ignore-i18next-interpolation
Interpolation example: There are {{number}} apples
Nesting example: There are $t(number) apples

ICU MessageFormat

New in version 4.9.

Summary: Syntax errors and/or placeholder mismatches in ICU MessageFormat strings.
Scope: translated strings
Check class: weblate.checks.icu.ICUMessageFormatCheck
Flag to enable: icu-message-format
Flag to ignore: ignore-icu-message-format
Interpolation example: There {number, plural, one {is one apple} other {are # apples}}.

This check has support for both pure ICU MessageFormat messages as well as ICU with simple XML tags. You can configure the behavior of this check by using icu-flags:*, either by opting into XML support or by disabling certain sub-checks. For example, the following flag enables XML support while disabling validation of plural sub-messages:

`xml`	Enable support for simple XML tags. By default, XML tags are parsed loosely. Stray `<` characters are ignored if they are not reasonably part of a tag.
`strict-xml`	Enable support for strict XML tags. All `<` characters must be escaped if they are not part of a tag.
`-highlight`	Disable highlighting placeholders in the editor.
`-require_other`	Disable requiring sub-messages to have an `other` selector.
`-submessage_selectors`	Skip checking that sub-message selectors match the source.
`-types`	Skip checking that placeholder types match the source.
`-extra`	Skip checking that no placeholders are present that were not present in the source string.
`-missing`	Skip checking that no placeholders are missing that were present in the source string.

Additionally, when strict-xml is not enabled but xml is enabled, you can use the icu-tag-prefix:PREFIX flag to require that all XML tags start with a specific string. For example, the following flag will only allow XML tags to be matched if they start with <x::

This would match <x:link>click here</x:link> but not <strong>this</strong>.

Java format

Summary: Java format string does not match source
Scope: translated strings
Check class: weblate.checks.format.JavaFormatCheck
Flag to enable: java-format

Has been translated

Summary: This string has been translated in the past
Scope: all strings
Check class: weblate.checks.consistency.TranslatedCheck
Flag to ignore: ignore-translated

Means a string has been translated already. This can happen when the translations have been reverted in VCS or lost otherwise.

Inconsistent

Summary: This string has more than one translation in this project or is not translated in some components.
Scope: all strings
Check class: weblate.checks.consistency.ConsistencyCheck
Flag to ignore: ignore-inconsistent

Weblate checks translations of the same string across all translation within a project to help you keep consistent translations.

The check fails on differing translations of one string within a project. This can also lead to inconsistencies in displayed checks. You can find other translations of this string on the Other occurrences tab.

This check applies to all components in a project that have Allow translation propagation turned on.

Hint

For performance reasons, the check might not find all inconsistencies, it limits number of matches.

Note

This check also fires in case the string is translated in one component and not in another. It can be used as a quick way to manually handle strings which are not translated in some components just by clicking on the Use this translation button displayed on each line in the Other occurrences tab.

You can use Automatic translation addon to automate translating of newly added strings which are already translated in another component.

Kashida letter used

New in version 3.5.

Summary: The decorative kashida letters should not be used
Scope: translated strings
Check class: weblate.checks.chars.KashidaCheck
Flag to ignore: ignore-kashida

Maximum length of translation

Summary: Translation should not exceed given length
Scope: translated strings
Check class: weblate.checks.chars.MaxLengthCheck
Flag to enable: max-length
Flag to ignore: ignore-max-length

Checks that translations are of acceptable length to fit available space. This only checks for the length of translation characters.

Unlike the other checks, the flag should be set as a key:value pair like max-length:100.

Hint

This check looks at number of chars, what might not be the best metric when using proportional fonts to render the text. The Maximum size of translation check does check actual rendering of the text.

The replacements: flag might be also useful to expand placeables before checking the string.

When xml-text flag is also used, the length calculation ignores XML tags.

Maximum size of translation

Summary: Translation rendered text should not exceed given size
Scope: translated strings
Check class: weblate.checks.render.MaxSizeCheck
Flag to enable: max-size
Flag to ignore: ignore-max-size

New in version 3.7.

Translation rendered text should not exceed given size. It renders the text with line wrapping and checks if it fits into given boundaries.

This check needs one or two parameters - maximal width and maximal number of lines. In case the number of lines is not provided, one line text is considered.

You can also configure used font by font-* directives (see Customizing behavior using flags), for example following translation flags say that the text rendered with ubuntu font size 22 should fit into two lines and 500 pixels:

max-size:500:2, font-family:ubuntu, font-size:22

Hint

You might want to set font-* directives in Component configuration to have the same font configured for all strings within a component. You can override those values per string in case you need to customize it per string.

The replacements: flag might be also useful to expand placeables before checking the string.

When xml-text flag is also used, the length calculation ignores XML tags.

Mismatched \n

Summary: Number of \n in translation does not match source
Scope: translated strings
Check class: weblate.checks.chars.EscapedNewlineCountingCheck
Flag to ignore: ignore-escaped-newline

Usually escaped newlines are important for formatting program output. Check fails if the number of \n literals in translation do not match the source.

Mismatched colon

Summary: Source and translation do not both end with a colon
Scope: translated strings
Check class: weblate.checks.chars.EndColonCheck
Flag to ignore: ignore-end-colon

Checks that colons are replicated between both source and translation. The presence of colons is also checked for various languages where they do not belong (Chinese or Japanese).

See also

Colon on Wikipedia

Mismatched ellipsis

Summary: Source and translation do not both end with an ellipsis
Scope: translated strings
Check class: weblate.checks.chars.EndEllipsisCheck
Flag to ignore: ignore-end-ellipsis

Checks that trailing ellipses are replicated between both source and translation. This only checks for real ellipsis (…) not for three dots (...).

An ellipsis is usually rendered nicer than three dots in print, and sounds better with text-to-speech.

Ellipsis on Wikipedia

Mismatched exclamation mark

Summary: Source and translation do not both end with an exclamation mark
Scope: translated strings
Check class: weblate.checks.chars.EndExclamationCheck
Flag to ignore: ignore-end-exclamation

Mismatched full stop

Summary: Source and translation do not both end with a full stop
Scope: translated strings
Check class: weblate.checks.chars.EndStopCheck
Flag to ignore: ignore-end-stop

Checks that full stops are replicated between both source and translation. The presence of full stops is checked for various languages where they do not belong (Chinese, Japanese, Devanagari or Urdu).

See also

Full stop on Wikipedia

Mismatched question mark

Summary: Source and translation do not both end with a question mark
Scope: translated strings
Check class: weblate.checks.chars.EndQuestionCheck
Flag to ignore: ignore-end-question

Mismatched semicolon

Summary: Source and translation do not both end with a semicolon
Scope: translated strings
Check class: weblate.checks.chars.EndSemicolonCheck

Semicolon on Wikipedia

Mismatching line breaks

Summary: Number of new lines in translation does not match source
Scope: translated strings
Check class: weblate.checks.chars.NewLineCountCheck
Flag to ignore: ignore-newline-count

Usually newlines are important for formatting program output. Check fails if the number of \n literals in translation do not match the source.

Missing plurals

Summary: Some plural forms are not translated
Scope: translated strings
Check class: weblate.checks.consistency.PluralsCheck
Flag to ignore: ignore-plurals

Checks that all plural forms of a source string have been translated. Specifics on how each plural form is used can be found in the string definition.

Failing to fill in plural forms will in some cases lead to displaying nothing when the plural form is in use.

Placeholders

New in version 3.9.

Summary: Translation is missing some placeholders
Scope: translated strings
Check class: weblate.checks.placeholders.PlaceholderCheck
Flag to enable: placeholders
Flag to ignore: ignore-placeholders

Changed in version 4.3: You can use regular expression as placeholder.

Translation is missing some placeholders. These are either extracted from the translation file or defined manually using placeholders flag, more can be separated with colon, strings with space can be quoted:

placeholders:$URL$:$TARGET$:"some long text"

In case you have some syntax for placeholders, you can use a regular expression:

placeholders:r"%[^% ]%"

Punctuation spacing

New in version 3.9.

Summary: Missing non breakable space before double punctuation sign
Scope: translated strings
Check class: weblate.checks.chars.PunctuationSpacingCheck
Flag to ignore: ignore-punctuation-spacing

Checks that there is non breakable space before double punctuation sign (exclamation mark, question mark, semicolon and colon). This rule is used only in a few selected languages like French or Breton, where space before double punctuation sign is a typographic rule.

Regular expression

New in version 3.9.

Summary: Translation does not match regular expression:
Scope: translated strings
Check class: weblate.checks.placeholders.RegexCheck
Flag to enable: regex
Flag to ignore: ignore-regex

Translation does not match regular expression. The expression is either extracted from the translation file or defined manually using regex flag:

regex:^foo|bar$

Summary: Some plural forms are translated in the same way
Scope: translated strings
Check class: weblate.checks.consistency.SamePluralsCheck
Flag to ignore: ignore-same-plurals

Check that fails if some plural forms are duplicated in the translation. In most languages they have to be different.

Starting newline

Summary: Source and translation do not both start with a newline
Scope: translated strings
Check class: weblate.checks.chars.BeginNewlineCheck
Flag to ignore: ignore-begin-newline

Newlines usually appear in source strings for good reason, omissions or additions can lead to formatting problems when the translated text is put to use.

See also

Trailing newline

Starting spaces

Summary: Source and translation do not both start with same number of spaces
Scope: translated strings
Check class: weblate.checks.chars.BeginSpaceCheck
Flag to ignore: ignore-begin-space

A space in the beginning of a string is usually used for indentation in the interface and thus important to keep.

Trailing newline

Summary: Source and translation do not both end with a newline
Scope: translated strings
Check class: weblate.checks.chars.EndNewlineCheck
Flag to ignore: ignore-end-newline

Newlines usually appear in source strings for good reason, omissions or additions can lead to formatting problems when the translated text is put to use.

Starting newline

Trailing space

Summary: Source and translation do not both end with a space
Scope: translated strings
Check class: weblate.checks.chars.EndSpaceCheck
Flag to ignore: ignore-end-space

Checks that trailing spaces are replicated between both source and translation.

Trailing space is usually utilized to space out neighbouring elements, so removing it might break layout.

Unchanged translation

Summary: Source and translation are identical
Scope: translated strings
Check class: weblate.checks.same.SameCheck
Flag to ignore: ignore-same

Happens if the source and corresponding translation strings is identical, down to at least one of the plural forms. Some strings commonly found across all languages are ignored, and various markup is stripped. This reduces the number of false positives.

This check can help find strings mistakenly untranslated.

The default behavior of this check is to exclude words from the built-in blacklist from the checking. These are words which are frequently not being translated. This is useful to avoid false positives on short strings, which consist only of single word which is same in several languages. This blacklist can be disabled by adding strict-same flag to string or component.

Unsafe HTML

New in version 3.9.

Summary: The translation uses unsafe HTML markup
Scope: translated strings
Check class: weblate.checks.markup.SafeHTMLCheck
Flag to enable: safe-html
Flag to ignore: ignore-safe-html

The translation uses unsafe HTML markup. This check has to be enabled using safe-html flag (see Customizing behavior using flags). There is also accompanied autofixer which can automatically sanitize the markup.

Hint

When md-text flag is also used, the Markdown style links are also allowed.

See also

The HTML check is performed by the Bleach library developed by Mozilla.

URL

New in version 3.5.

Summary: The translation does not contain an URL
Scope: translated strings
Check class: weblate.checks.markup.URLCheck
Flag to enable: url
Flag to ignore: ignore-url

The translation does not contain an URL. This is triggered only in case the unit is marked as containing URL. In that case the translation has to be a valid URL.

XML markup

Summary: XML tags in translation do not match source
Scope: translated strings
Check class: weblate.checks.markup.XMLTagsCheck
Flag to ignore: ignore-xml-tags

This usually means the resulting output will look different. In most cases this is not a desired result from changing the translation, but occasionally it is.

Checks that XML tags are replicated between both source and translation.

Note

This check is disabled by the safe-html flag as the HTML cleanup done by it can produce HTML markup which is not valid XML.

XML syntax

New in version 2.8.

Summary: The translation is not valid XML
Scope: translated strings
Check class: weblate.checks.markup.XMLValidityCheck
Flag to ignore: ignore-xml-invalid

The XML markup is not valid.

Note

This check is disabled by the safe-html flag as the HTML cleanup done by it can produce HTML markup which is not valid XML.

Zero-width space

Summary: Translation contains extra zero-width space character
Scope: translated strings
Check class: weblate.checks.chars.ZeroWidthSpaceCheck
Flag to ignore: ignore-zero-width-space

Zero-width space (<U+200B>) characters are used to break messages within words (word wrapping).

As they are usually inserted by mistake, this check is triggered once they are present in translation. Some programs might have problems when this character is used.

See also

Zero width space on Wikipedia

Source checks

Source checks can help developers improve the quality of source strings.

Ellipsis

Summary: The string uses three dots (…) instead of an ellipsis character (…)
Scope: source strings
Check class: weblate.checks.source.EllipsisCheck
Flag to ignore: ignore-ellipsis

This fails when the string uses three dots (...) when it should use an ellipsis character (…).

Using the Unicode character is in most cases the better approach and looks better rendered, and may sound better with text-to-speech.

Ellipsis on Wikipedia

ICU MessageFormat syntax

New in version 4.9.

Summary: Syntax errors in ICU MessageFormat strings.
Scope: source strings
Check class: weblate.checks.icu.ICUSourceCheck
Flag to ignore: ignore-icu-message-format-syntax

See also

ICU MessageFormat

Long untranslated

New in version 4.1.

Summary: The string has not been translated for a long time
Scope: source strings
Check class: weblate.checks.source.LongUntranslatedCheck
Flag to ignore: ignore-long-untranslated

When the string has not been translated for a long time, it can indicate a problem in a source string making it hard to translate.

Multiple failing checks

Summary: The translations in several languages have failing checks
Scope: source strings
Check class: weblate.checks.source.MultipleFailingCheck
Flag to ignore: ignore-multiple-failures

Numerous translations of this string have failing quality checks. This is usually an indication that something could be done to improve the source string.

This check failing can quite often be caused by a missing full stop at the end of a sentence, or similar minor issues which translators tend to fix in translation, while it would be better to fix it in the source string.

Multiple unnamed variables

New in version 4.1.

Summary: There are multiple unnamed variables in the string, making it impossible for translators to reorder them
Scope: source strings
Check class: weblate.checks.format.MultipleUnnamedFormatsCheck
Flag to ignore: ignore-unnamed-format

There are multiple unnamed variables in the string, making it impossible for translators to reorder them.

Consider using named variables instead to allow translators to reorder them.

Unpluralised

Summary: The string is used as plural, but not using plural forms
Scope: source strings
Check class: weblate.checks.source.OptionalPluralCheck
Flag to ignore: ignore-optional-plural

The string is used as a plural, but does not use plural forms. In case your translation system supports this, you should use the plural aware variant of it.

For example with Gettext in Python it could be:

from gettext import ngettext

print ngettext("Selected %d file", "Selected %d files", files) % files

Searching

New in version 3.9.

Advanced queries using boolean operations, parentheses, or field specific lookup can be used to find the strings you want.

When no field is defined, the lookup happens on Source, Translate and Context fields.

Simple search

Any phrase typed into the search box is split into words. Strings containing any of them are shown. To look for an exact phrase, put “the searchphrase” into quotes (both single (’) and double (”) quotes will work): "this is a quoted string" or 'another quoted string'.

Fields

source:TEXT: Source string case-insensitive search.
target:TEXT: Target string case-insensitive search.

explanation:TEXT: Search in explanations.

Boolean operators

You can combine lookups using AND, OR, NOT and parentheses to form complex queries. For example: state:translated AND (source:hello OR source:bar)

Field operators

You can specify operators, ranges or partial lookups for date or numeric searches:

state:>=translated: State is translated or better (approved).
changed:2019: Changed in year 2019.
changed:[2019-03-01 to 2019-04-01]: Changed between two given dates.

Exact operators

You can do an exact match query on different string fields using = operator. For example, to search for all source strings exactly matching hello world, use: source:="hello world". For searching single word expressions, you can skip quotes. For example, to search for all source strings matching hello, you can use: source:=hello.

Searching for changes

New in version 4.4.

Searching for history events can be done using change_action and change_time operators.

For example, searching for strings marked for edit in 2018 can be entered as change_time:2018 AND change_action:marked-for-edit or change_time:2018 AND change_action:"Marked for edit".

Regular expressions

Anywhere text is accepted you can also specify a regular expression as r"regexp".

For example, to search for all source strings which contain any digit between 2 and 5, use source:r"[2-5]".

Predefined queries

You can select out of predefined queries on the search page, this allows you to quickly access the most frequent searches:

Ordering the results

There are many options to order the strings according to your needs:

Translation workflows

Using Weblate is a process that brings your users closer to you, by bringing you closer to your translators. It is up to you to decide how many of its features you want to make use of.

The following is not a complete list of ways to configure Weblate. You can base other workflows on the most usual examples listed here.

Translation access

The access control is not discussed in detail as a whole in the workflows, as most of its options can be applied to any workflow. Please consult the respective documentation on how to manage access to translations.

In the following chapters, any user means a user who has access to the translation. It can be any authenticated user if the project is public, or a user that has a Translate permission for the project.

Translation states

Each translated string can be in one of following states:

Untranslated: Translation is empty, it might or not be stored in the file, depending on the file format.
Needs editing: Translation needs editing, this is usually the result of a source string change, fuzzy matching or translator action. The translation is stored in the file, depending on the file format it might be marked as needing edit (for example as it gets a fuzzy flag in the Gettext file).
Waiting for review: Translation is made, but not reviewed. It is stored in the file as a valid translation.
Approved: Translation has been approved in the review. It can no longer be changed by translators, but only by reviewers. Translators can only add suggestions to it.
Suggestions: Suggestions are stored in Weblate only and not in the translation file.

The states are represented in the translation files when possible.

Hint

In case file format you use does not support storing states, you might want to use Flag unchanged translations as “Needs editing” addon to flag unchanged strings as needing editing.

Direct translation

This is most usual setup for smaller teams, anybody can directly translate. This is also the default setup in Weblate.

Any user can edit translations.
Suggestions are optional ways to suggest changes, when translators are not sure about the change.

Setting	Value	Note
Enable reviews	off	Configured at project level.
Enable suggestions	on	It is useful for users to be able to suggest when they are not sure.
Suggestion voting	off
Autoaccept suggestions	0
Translators group	Users	Or Translate with per-project access control.
Reviewers group	N/A	Not used.

Peer review

With this workflow, anybody can add suggestions, and need approval from additional member(s) before it is accepted as a translation.

Any user can add suggestions.
Any user can vote for suggestions.
Suggestions become translations when given a predetermined number of votes.

Setting	Value	Note
Enable reviews	off	Configured at project level.
Enable suggestions	on
Suggestion voting	off
Autoaccept suggestions	1	You can set higher value to require more peer reviews.
Translators group	Users	Or Translate with per-project access control.
Reviewers group	N/A	Not used, all translators review.

Dedicated reviewers

New in version 2.18: The proper review workflow is supported since Weblate 2.18.

With dedicated reviewers you have two groups of users, one able to submit translations, and one able to review them to ensure translations are consistent and that the quality is good.

Any user can edit unapproved translations.
Reviewer can approve / unapprove strings.
Reviewer can edit all translations (including approved ones).
Suggestions can also be used to suggest changes for approved strings.

Setting	Value	Note
Enable reviews	on	Configured at project level.
Enable suggestions	off	It is useful for users to be able to suggest when they are not sure.
Suggestion voting	off
Autoaccept suggestions	0
Translators group	Users	Or Translate with per-project access control.
Reviewers group	Reviewers	Or Review with per-project access control.

Turning on reviews

Reviews can be turned on in the project configuration, from the Workflow subpage of project settings (to be found in the Manage → Settings menu):

Note

Depending on Weblate configuration, the setting might not be available to you. For example on Hosted Weblate this is not available for projects hosted for free.

Quality gateway for the source strings

In many cases the original source language strings are coming from developers, because they write the code and provide initial strings. However developers are often not a native speakers in the source language and do not provide desired quality of the source strings. The intermediate translation can help you in addressing this - there is additional quality gateway for the strings between developers and translators and users.

By setting Intermediate language file, this file will be used as source for the strings, but it will be edited to source language to polish it. Once the string is ready in the source language, it will be also available for translators to translate into additional languages.

Source strings reviews

With Enable source reviews enabled, the review process can be applied on the source strings. Once enabled, users can report issues in the source strings. The actual process depends on whether you use bilingual or monolingual formats.

For monolingual formats, the source string review behaves similarly as with Dedicated reviewers - once issue is reported on the source string, it is marked as Needs editing.

The bilingual formats do not allow direct editing of the source strings (these are typically extracted directly from the source code). In this case Source needs review label is attached to strings reported by translators. You should review such strings and either edit them in the source or remove the label.

Frequently Asked Questions

Configuration

How to create an automated workflow?

Weblate can handle all the translation things semi-automatically for you. If you give it push access to your repository, the translations can happen without interaction, unless some merge conflict occurs.

Set up your Git repository to tell Weblate when there is any change, see Notification hooks for info on how to do it.
Set a push URL at your Component configuration in Weblate, this allows Weblate to push changes to your repository.
Turn on Push on commit on your Component configuration in Weblate, this will make Weblate push changes to your repository whenever they happen at Weblate.

How to access repositories over SSH?

Please see Accessing repositories for info on setting up SSH keys.

How to fix merge conflicts in translations?

Merge conflicts happen from time to time when the translation file is changed in both Weblate and the upstream repository concurrently. You can usually avoid this by merging Weblate translations prior to making changes in the translation files (e.g. before running msgmerge). Just tell Weblate to commit all pending translations (you can do it in Repository maintenance in the Manage menu) and merge the repository (if automatic push is not on).

If you’ve already encountered a merge conflict, the easiest way to solve all conflicts locally on your machine, is to add Weblate as a remote repository, merge it into upstream and fix any conflicts. Once you push changes back, Weblate will be able to use the merged version without any other special actions.

Note

Depending on your setup, access to the Weblate repository might require authentication. When using the built-in Git exporter in Weblate, you authenticate with your username and the API key.

# Commit all pending changes in Weblate, you can do this in the UI as well:
wlc commit
# Lock the translation in Weblate, again this can be done in the UI as well:
wlc lock
# Add Weblate as remote:
git remote add weblate https://hosted.weblate.org/git/project/component/
# You might need to include credentials in some cases:
git remote add weblate https://username:APIKEY@hosted.weblate.org/git/project/component/

# Update weblate remote:
git remote update weblate

# Merge Weblate changes:
git merge weblate/main

# Resolve conflicts:
edit …
git add …
…
git commit

# Push changes to upstream repository, Weblate will fetch merge from there:
git push

# Open Weblate for translation:
wlc unlock

If you’re using multiple branches in Weblate, you can do the same to all of them:

# Add and update Weblate remotes
git remote add weblate-one https://hosted.weblate.org/git/project/one/
git remote add weblate-second https://hosted.weblate.org/git/project/second/
git remote update weblate-one weblate-second

# Merge QA_4_7 branch:
git checkout QA_4_7
git merge weblate-one/QA_4_7
... # Resolve conflicts
git commit

# Merge main branch:
git checkout main
git merge weblates-second/main
... # Resolve conflicts
git commit

# Push changes to the upstream repository, Weblate will fetch the merge from there:
git push

In case of gettext PO files, there is a way to merge conflicts in a semi-automatic way:

Fetch and keep a local clone of the Weblate Git repository. Also get a second fresh local clone of the upstream Git repository (i. e. you need two copies of the upstream Git repository: An intact and a working copy):

# Add remote:
git remote add weblate /path/to/weblate/snapshot/

# Update Weblate remote:
git remote update weblate

# Merge Weblate changes:
git merge weblate/main

# Resolve conflicts in the PO files:

# Push changes to the upstream repository, Weblate will fetch merge from there:
git push

How do I translate several branches at once?

Weblate supports pushing translation changes within one Project configuration. For every Component configuration which has it turned on (the default behavior), the change made is automatically propagated to others. This way translations are kept synchronized even if the branches themselves have already diverged quite a lot, and it is not possible to simply merge translation changes between them.

Once you merge changes from Weblate, you might have to merge these branches (depending on your development workflow) discarding differences:

git merge -s ours origin/maintenance

How to translate multi-platform projects?

Weblate supports a wide range of file formats (see Supported file formats) and the easiest approach is to use the native format for each platform.

Once you have added all platform translation files as components in one project (see Adding translation projects and components), you can utilize the translation propagation feature (turned on by default, and can be turned off in the Component configuration) to translate strings for all platforms at once.

How to export the Git repository that Weblate uses?

There is nothing special about the repository, it lives under the DATA_DIR directory and is named vcs/<project>/<component>/. If you have SSH access to this machine, you can use the repository directly.

For anonymous access, you might want to run a Git server and let it serve the repository to the outside world.

Alternatively, you can use Git exporter inside Weblate to automate this.

What are the options for pushing changes back upstream?

This heavily depends on your setup, Weblate is quite flexible in this area. Here are examples of some workflows used with Weblate:

Weblate automatically pushes and merges changes (see How to create an automated workflow?).
You manually tell Weblate to push (it needs push access to the upstream repository).
Somebody manually merges changes from the Weblate git repository into the upstream repository.
Somebody rewrites history produced by Weblate (e.g. by eliminating merge commits), merges changes, and tells Weblate to reset the content in the upstream repository.

Of course you are free to mix all of these as you wish.

How can I limit Weblate access to only translations, without exposing source code to it?

You can use git submodule for separating translations from source code while still having them under version control.

Create a repository with your translation files.

Add this as a submodule to your code:

git submodule add git@example.com:project-translations.git path/to/translations

Link Weblate to this repository, it no longer needs access to the repository containing your source code.
You can update the main repository with translations from Weblate by:
```
git submodule update --remote path/to/translations
```

Please consult the git submodule documentation for more details.

How can I check whether my Weblate is set up properly?

Weblate includes a set of configuration checks which you can see in the admin interface, just follow the Performance report link in the admin interface, or open the /manage/performance/ URL directly.

Why are all commits committed by Weblate <noreply@weblate.org>?

This is the default committer name, configured when you create a translation component. You can change it in the administration at any time.

The author of every commit (if the underlying VCS supports it) is still recorded correctly as the user that made the translation.

Component configuration

How to move files in the repository without losing history in Weblate?

To keep the history, comments, or screenshots linked to strings after changing the files location you need to ensure that these strings are never deleted in Weblate. These removals can happen in case the Weblate repository is updated, but the component configuration still points to the old files. This makes Weblate assume that it should delete all the translations.

The solution to this is to perform the operation in sync with Weblate:

Lock the affected component in Weblate.
Commit any pending changes and merge them into the upstream repository.
Disable receiving webhooks the Project configuration; this prevents Weblate from immediately seeing changes in the repository.
Do any needed changes in the repo (for example using git mv), push them to the upstream repository.
Change the Component configuration to match the new setup; upon changing configuration, Weblate will fetch the updated repository and notice the changed locations while keeping existing strings.
Unlock the component and re-enable hooks in the project configuration.

Usage

How do I review the translations of others?

There are several review based workflows available in Weblate, see Translation workflows.
You can subscribe to any changes made in Notifications and then check others contributions as they come in by e-mail.
There is a review tool available at the bottom of the translation view, where you can choose to browse translations made by others since a given date.

Translation workflows

How do I provide feedback on a source string?

On context tabs below translation, you can use the Comments tab to provide feedback on a source string, or discuss it with other translators.

How can I use existing translations while translating?

All translations within Weblate can be used thanks to shared translation memory.
You can import existing translation memory files into Weblate.
Use the import functionality to load compendium as translations, suggestions or translations needing review. This is the best approach for a one-time translation using a compendium or a similar translation database.
You can set up tmserver with all databases you have and let Weblate use it. This is good when you want to use it several times during translation.
Another option is to translate all related projects in a single Weblate instance, which will make it automatically pick up translations from other projects as well.

Does Weblate update translation files besides translations?

Weblate tries to limit changes in translation files to a minimum. For some file formats it might unfortunately lead to reformatting the file. If you want to keep the file formatted your way, please use a pre-commit hook for that.

Updating target language files

Where do language definitions come from and how can I add my own?

The basic set of language definitions is included within Weblate and Translate-toolkit. This covers more than 150 languages and includes info about plural forms or text direction.

You are free to define your own languages in the administrative interface, you just need to provide info about it.

See also

Language definitions

Can Weblate highlight changes in a fuzzy string?

Weblate supports this, however it needs the data to show the difference.

For Gettext PO files, you have to pass the parameter --previous to msgmerge when updating PO files, for example:

msgmerge --previous -U po/cs.po po/phpmyadmin.pot

For monolingual translations, Weblate can find the previous string by ID, so it shows the differences automatically.

Why does Weblate still show old translation strings when I’ve updated the template?

Weblate does not try to manipulate the translation files in any way other than allowing translators to translate. So it also does not update the translatable files when the template or source code have been changed. You simply have to do this manually and push changes to the repository, Weblate will then pick up the changes automatically.

Note

It is usually a good idea to merge changes done in Weblate before updating translation files, as otherwise you will usually end up with some conflicts to merge.

For example with gettext PO files, you can update the translation files using the msgmerge tool:

msgmerge -U locale/cs/LC_MESSAGES/django.mo locale/django.pot

In case you want to do the update automatically, you can install addon Update PO files to match POT (msgmerge).

Troubleshooting

Requests sometimes fail with “too many open files” error

This happens sometimes when your Git repository grows too much and you have many of them. Compressing the Git repositories will improve this situation.

The easiest way to do this is to run:

# Go to DATA_DIR directory
cd data/vcs
# Compress all Git repositories
for d in */* ; do
    pushd $d
    git gc
    popd
done

See also

DATA_DIR

When accessing the site I get a “Bad Request (400)” error

This is most likely caused by an improperly configured ALLOWED_HOSTS. It needs to contain all hostnames you want to access on your Weblate. For example:

ALLOWED_HOSTS = ["weblate.example.com", "weblate", "localhost"]

See also

Allowed hosts setup

What does mean “There are more files for the single language (en)”?

This typically happens when you have translation file for source language. Weblate keeps track of source strings and reserves source language for this. The additional file for same language is not processed.

In case the translation to the source language is desired, please change the Source language in the component settings.
In case the translation file for the source language is not needed, please remove it from the repository.
In case the translation file for the source language is needed, but should be ignored by Weblate, please adjust the Language filter to exclude it.

Hint

You might get similar error message for other languages as well. In that case the most likely reason is that several files map to single language in Weblate.

This can be caused by using obsolete language codes together with new one (ja and jp for Japanese) or including both country specific and generic codes (fr and fr_FR). See Parsing language codes for more details.

Features

Does Weblate support other VCSes than Git and Mercurial?

Weblate currently does not have native support for anything other than Git (with extended support for GitHub, Gerrit and Subversion) and Mercurial, but it is possible to write backends for other VCSes.

You can also use Git remote helpers in Git to access other VCSes.

Weblate also supports VCS-less operation, see Local files.

Note

For native support of other VCSes, Weblate requires using distributed VCS, and could probably be adjusted to work with anything other than Git and Mercurial, but somebody has to implement this support.

See also

Version control integration

How does Weblate credit translators?

Every change made in Weblate is committed into VCS under the translators name. This way every single change has proper authorship, and you can track it down using the standard VCS tools you use for code.

Additionally, when the translation file format supports it, the file headers are updated to include the translator’s name.

Why does Weblate force showing all PO files in a single tree?

Weblate was designed in a way that every PO file is represented as a single component. This is beneficial for translators, so they know what they are actually translating.

Changed in version 4.2: Translators can translate all the components of a project into a specific language as a whole.

Why does Weblate use language codes such sr_Latn or zh_Hant?

These are language codes defined by RFC 5646 to better indicate that they are really different languages instead previously wrongly used modifiers (for @latin variants) or country codes (for Chinese).

Weblate still understands legacy language codes and will map them to current one - for example sr@latin will be handled as sr_Latn or zh@CN as zh_Hans.

Note

Weblate defaults to POSIX style language codes with underscore, see Language definitions for more details.

Supported file formats

Weblate supports most translation format understood by translate-toolkit, however each format being slightly different, some issues with formats that are not well tested can arise.

See also

Translation Related File Formats

Note

When choosing a file format for your application, it’s better to stick some well established format in the toolkit/platform you use. This way your translators can additionally use whatever tools they are used to, and will more likely contribute to your project.

Bilingual and monolingual formats

Both monolingual and bilingual formats are supported. Bilingual formats store two languages in single file—source and translation (typical examples are GNU gettext, XLIFF or Apple iOS strings). On the other side, monolingual formats identify the string by ID, and each language file contains only the mapping of those to any given language (typically Android string resources). Some file formats are used in both variants, see the detailed description below.

For correct use of monolingual files, Weblate requires access to a file containing complete list of strings to translate with their source—this file is called Monolingual base language file within Weblate, though the naming might vary in your paradigm.

Additionally this workflow can be extended by utilizing Intermediate language file to include strings provided by developers, but not to be used as is in the final strings.

Automatic detection

Weblate can automatically detect several widespread file formats, but this detection can harm your performance and will limit features specific to given file format (for example automatic addition of new translations).

1: See Bilingual and monolingual formats
2: Plurals are necessary to properly localize strings with variable count.
3: Source string descriptions can be used to pass additional info about the string to translate.
4: Context is used to differentiate identical strings used in different scopes (for example Sun can be used as an abbreviated name of the day “Sunday” or as the name of our closest star).
5: Location of a string in source code might help proficient translators figure out how the string is used.
6: Additional states supported by the file format in addition to “Not translated” and “Translated”.
7: XML comment placed before the <string> element, parsed as a source string description.
8: See Customizing behavior using flags
9(1,2): The gettext type comments are used as flags.
10(1,2,3,4,5,6): The flags are extracted from the non-standard attribute weblate-flags for all XML based formats. Additionally max-length:N is supported through the maxwidth attribute as defined in the XLIFF standard, see Specifying translation flags.
11: The plurals are supported only for Laravel which uses in string syntax to define them, see Localization in Laravel.
12: Plurals are handled in the syntax of the strings and not exposed as plurals in Weblate.

Read-only strings

New in version 3.10.

Read-only strings from translation files will be included, but can not be edited in Weblate. This feature is natively supported by few formats (XLIFF and Android string resources), but can be emulated in others by adding a read-only flag, see Customizing behavior using flags.

GNU gettext

Most widely used format for translating libre software.

Contextual info stored in the file is supported by adjusting its headers or linking to corresponding source files.

The bilingual gettext PO file typically looks like this:

#: weblate/media/js/bootstrap-datepicker.js:1421
msgid "Monday"
msgstr "Pondělí"

#: weblate/media/js/bootstrap-datepicker.js:1421
msgid "Tuesday"
msgstr "Úterý"

#: weblate/accounts/avatar.py:163
msgctxt "No known user"
msgid "None"
msgstr "Žádný"

Typical Weblate Component configuration
Filemask	`po/*.po`
Monolingual base language file	Empty
Template for new translations	`po/messages.pot`
File format	Gettext PO file

Monolingual gettext

Some projects decide to use gettext as monolingual formats—they code just the IDs in their source code and the string then needs to be translated to all languages, including English. This is supported, though you have to choose this file format explicitly when importing components into Weblate.

The monolingual gettext PO file typically looks like this:

#: weblate/media/js/bootstrap-datepicker.js:1421
msgid "day-monday"
msgstr "Pondělí"

#: weblate/media/js/bootstrap-datepicker.js:1421
msgid "day-tuesday"
msgstr "Úterý"

#: weblate/accounts/avatar.py:163
msgid "none-user"
msgstr "Žádný"

While the base language file will be:

#: weblate/media/js/bootstrap-datepicker.js:1421
msgid "day-monday"
msgstr "Monday"

#: weblate/media/js/bootstrap-datepicker.js:1421
msgid "day-tuesday"
msgstr "Tuesday"

#: weblate/accounts/avatar.py:163
msgid "none-user"
msgstr "None"

Typical Weblate Component configuration
Filemask	`po/*.po`
Monolingual base language file	`po/en.po`
Template for new translations	`po/messages.pot`
File format	Gettext PO file (monolingual)

XLIFF

XML-based format created to standardize translation files, but in the end it is one of many standards, in this area.

XML Localization Interchange File Format (XLIFF) is usually used as bilingual, but Weblate supports it as monolingual as well.

See also

XML Localization Interchange File Format (XLIFF) specification

Translation states

Changed in version 3.3: Weblate ignored the state attribute prior to the 3.3 release.

The state attribute in the file is partially processed and mapped to the “Needs edit” state in Weblate (the following states are used to flag the string as needing edit if there is a target present: new, needs-translation, needs-adaptation, needs-l10n). Should the state attribute be missing, a string is considered translated as soon as a <target> element exists.

If the translation string has approved="yes", it will also be imported into Weblate as “Approved”, anything else will be imported as “Waiting for review” (which matches the XLIFF specification).

While saving, Weblate doesn’t add those attributes unless necessary:

The state attribute is only added in case string is marked as needing edit.
The approved attribute is only added in case string has been reviewed.
In other cases the attributes are not added, but they are updated in case they are present.

That means that when using the XLIFF format, it is strongly recommended to turn on the Weblate review process, in order to see and change the approved state of strings.

Similarly upon importing such files (in the upload form), you should choose Import as translated under Processing of strings needing edit.

See also

Dedicated reviewers

Whitespace and newlines in XLIFF

Generally types or amounts of whitespace is not differentiated between in XML formats. If you want to keep it, you have to add the xml:space="preserve" flag to the string.

For example:

    <trans-unit id="10" approved="yes">
        <source xml:space="preserve">hello</source>
        <target xml:space="preserve">Hello, world!
</target>
    </trans-unit>

Specifying translation flags

You can specify additional translation flags (see Customizing behavior using flags) by using the weblate-flags attribute. Weblate also understands maxwidth and font attributes from the XLIFF specification:

<trans-unit id="10" maxwidth="100" size-unit="pixel" font="ubuntu;22;bold">
   <source>Hello %s</source>
</trans-unit>
<trans-unit id="20" maxwidth="100" size-unit="char" weblate-flags="c-format">
   <source>Hello %s</source>
</trans-unit>

The font attribute is parsed for font family, size and weight, the above example shows all of that, though only font family is required. Any whitespace in the font family is converted to underscore, so Source Sans Pro becomes Source_Sans_Pro, please keep that in mind when naming the font group (see Managing fonts).

String keys

Weblate identifies the units in the XLIFF file by resname attribute in case it is present and falls back to id (together with file tag if present).

The resname attribute is supposed to be human friendly identifier of the unit making it more suitable for Weblate to display instead of id. The resname has to be unique in the whole XLIFF file. This is required by Weblate and is not covered by the XLIFF standard - it does not put any uniqueness restrictions on this attribute.

Typical Weblate Component configuration for bilingual XLIFF

Java properties

Native Java format for translations.

Java properties are usually used as monolingual translations.

Weblate supports ISO-8859-1, UTF-8 and UTF-16 variants of this format. All of them support storing all Unicode characters, it is just differently encoded. In the ISO-8859-1, the Unicode escape sequences are used (for example zkou\u0161ka), all others encode characters directly either in UTF-8 or UTF-16.

Note

Loading escape sequences works in UTF-8 mode as well, so please be careful choosing the correct encoding set to match your application needs.

Typical Weblate Component configuration

INI translations are usually used as monolingual translations.

Typical Weblate Component configuration
Filemask	`language/*.ini`
Monolingual base language file	`language/en.ini`
Template for new translations	Empty
File format	INI File

Note

Weblate only extracts keys from sections within an INI file. In case your INI file lacks sections, you might want to use Joomla translations or Java properties instead.

Inno Setup INI translations

New in version 4.1.

Inno Setup INI file format for translations.

Inno Setup INI translations are usually used as monolingual translations.

Note

The only notable difference to INI translations is in supporting %n and %t placeholders for line break and tab.

Typical Weblate Component configuration
Filemask	`language/*.islu`
Monolingual base language file	`language/en.islu`

Qt Linguist .ts

Translation format used in Qt based applications.

Qt Linguist files are used as both bilingual and monolingual translations.

Typical Weblate Component configuration when using as bilingual
Filemask	`i18n/app.*.ts`
Monolingual base language file	Empty

Template for new translations	`i18n/app.en.ts`
File format	Qt Linguist Translation File

Android string resources

Android specific file format for translating applications.

Android string resources are monolingual, the Monolingual base language file is stored in a different location from the others res/values/strings.xml.

Typical Weblate Component configuration
Filemask	`res/values-*/strings.xml`
Monolingual base language file	`res/values/strings.xml`
Template for new translations	Empty
File format	Android String Resource

Note

Android string-array structures are not currently supported. To work around this, you can break your string arrays apart:

<string-array name="several_strings">
    <item>First string</item>
    <item>Second string</item>
</string-array>

become:

<string-array name="several_strings">
    <item>@string/several_strings_0</item>
    <item>@string/several_strings_1</item>
</string-array>
<string name="several_strings_0">First string</string>
<string name="several_strings_1">Second string</string>

The string-array that points to the string elements should be stored in a different file, and not be made available for translation.

This script may help pre-process your existing strings.xml files and translations: https://gist.github.com/paour/11291062

Apple iOS strings

Apple specific file format for translating applications, used for both iOS and iPhone/iPad application translations.

Apple iOS strings are usually used as bilingual translations.

Typical Weblate Component configuration
Filemask	`Resources/*.lproj/Localizable.strings`
Monolingual base language file	`Resources/en.lproj/Localizable.strings` or `Resources/Base.lproj/Localizable.strings`
Template for new translations	Empty
File format	iOS Strings (UTF-8)

PHP strings

PHP translations are usually monolingual, so it is recommended to specify a base file with (what is most often the) English strings.

Example file:

<?php
$LANG['foo'] = 'bar';
$LANG['foo1'] = 'foo bar';
$LANG['foo2'] = 'foo bar baz';
$LANG['foo3'] = 'foo bar baz bag';

Typical Weblate Component configuration
Filemask	`lang/*/texts.php`
Monolingual base language file	`lang/en/texts.php`

Laravel PHP strings

Changed in version 4.1.

The Laravel PHP localization files are supported as well with plurals:

<?php
return [
    'welcome' => 'Welcome to our application',
    'apples' => 'There is one apple|There are many apples',
];

PHP, Localization in Laravel

JSON files

New in version 2.0.

Changed in version 2.16: Since Weblate 2.16 and with translate-toolkit at-least 2.2.4, nested structure JSON files are supported as well.

Changed in version 4.3: The structure of JSON file is properly preserved even for complex situations which were broken in prior releases.

JSON format is used mostly for translating applications implemented in JavaScript.

Weblate currently supports several variants of JSON translations:

Simple key / value files, used for example by vue-i18n or react-intl.
Files with nested keys.
JSON i18next files
go-i18n JSON files
WebExtension JSON
ARB File

JSON translations are usually monolingual, so it is recommended to specify a base file with (what is most often the) English strings.

Example file:

{
  "Hello, world!\n": "Ahoj světe!\n",
  "Orangutan has %d banana.\n": "",
  "Try Weblate at https://demo.weblate.org/!\n": "",
  "Thank you for using Weblate.": ""
}

Nested files are supported as well (see above for requirements), such a file can look like:

{
  "weblate": {
    "hello": "Ahoj světe!\n",
    "orangutan": "",
    "try": "",
    "thanks": ""
  }
}

Hint

The JSON file and JSON nested structure file can both handle same type of files. Both preserve existing JSON structure when translating.

The only difference between them is when adding new strings using Weblate. The nested structure format parses the newly added key and inserts the new string into the matching structure. For example app.name key is inserted as:

{
   "app": {
      "name": "Weblate"
   }
}

Typical Weblate Component configuration
Filemask	`langs/translation-*.json`
Monolingual base language file	`langs/translation-en.json`

File format	JSON nested structure file

JSON i18next files

Changed in version 2.17: Since Weblate 2.17 and with translate-toolkit at-least 2.2.5, i18next JSON files with plurals are supported as well.

i18next is an internationalization framework written in and for JavaScript. Weblate supports its localization files with features such as plurals.

i18next translations are monolingual, so it is recommended to specify a base file with (what is most often the) English strings.

Note

Weblate supports the i18next JSON v3 format. The v2 and v1 variants are mostly compatible, with exception of how plurals are handled.

The v4 variant uses different approach for storing plurals and is currently not supported.

Example file:

{
  "hello": "Hello",
  "apple": "I have an apple",
  "apple_plural": "I have {{count}} apples",
  "apple_negative": "I have no apples"
}

Typical Weblate Component configuration

File format	i18next JSON file

go-i18n JSON files

New in version 4.1.

go-i18n translations are monolingual, so it is recommended to specify a base file with (what is most often the) English strings.

Note

Weblate supports the go-i18n JSON v1 format, for flat JSON formats please use JSON files. The v2 format with hash is currently not supported.

WebExtension JSON

New in version 2.16: This is supported since Weblate 2.16 and with translate-toolkit at-least 2.2.4.

File format used when translating extensions for Mozilla Firefox or Google Chromium.

Note

While this format is called JSON, its specification allows to include comments, which are not part of JSON specification. Weblate currently does not support file with comments.

Example file:

{
  "hello": {
    "message": "Ahoj světe!\n",
    "description": "Description",
    "placeholders": {
      "url": {
        "content": "$1",
        "example": "https://developer.mozilla.org"
      }
    }
  },
  "orangutan": {
    "message": "",
    "description": "Description"
  },
  "try": {

CSV files

New in version 2.4.

CSV files can contain a simple list of source and translation. Weblate supports the following files:

Files with header defining fields (location, source, target, ID, fuzzy, context, translator_comments, developer_comments). This is the recommended approach, as it is the least error prone. Choose CSV file as a file format.
Files with two fields—source and translation (in this order). Choose Simple CSV file as a file format.
Headerless files with fields in order defined by the translate-toolkit: location, source, target, ID, fuzzy, context, translator_comments, developer_comments. Choose CSV file as a file format.
Remember to define Monolingual base language file when your files are monolingual (see Bilingual and monolingual formats).

Warning

The CSV format currently automatically detects the dialect of the CSV file. In some cases the automatic detection might fail and you will get mixed results. This is especially true for CSV files with newlines in the values. As a workaround it is recommended to omit quoting characters.

Example file:

Thank you for using Weblate.,Děkujeme za použití Weblate.

Excel Open XML

New in version 3.2.

Excel Open XML (.xlsx) files can be imported and exported.

When uploading XLSX files for translation, be aware that only the active worksheet is considered, and there must be at least a column called source (which contains the source string) and a column called target (which contains the translation). Additionally there should be the column called context (which contains the context path of the translation string). If you use the XLSX download for exporting the translations into an Excel workbook, you already get a file with the correct file format.

Supporting other formats

Most formats supported by translate-toolkit which support serializing can be easily supported, but they did not (yet) receive any testing. In most cases some thin layer is needed in Weblate to hide differences in behavior of different translate-toolkit storages.

To add support for a new format, the preferred approach is to first implement support for it in the translate-toolkit.

Translation Related File Formats

Version control integration

Weblate currently supports Git (with extended support for GitHub, Gerrit and Subversion) and Mercurial as version control back-ends.

Accessing repositories

The VCS repository you want to use has to be accessible to Weblate. With a publicly available repository you just need to enter the correct URL (for example https://github.com/WeblateOrg/weblate.git), but for private repositories or for push URLs the setup is more complex and requires authentication.

Accessing repositories from Hosted Weblate

For Hosted Weblate there is a dedicated push user registered on GitHub, Bitbucket, Codeberg and GitLab (with the username weblate, e-mail hosted@weblate.org and, named Weblate push user). You need to add this user as a collaborator and give it appropriate permission to your repository (read-only is okay for cloning, write is required for pushing). Depending on service and your organization settings, this happens immediately, or requires confirmation on the Weblate side.

The weblate user on GitHub accepts invitations automatically within five minutes. Manual processing might be needed on the other services, so please be patient.

Once the weblate user is added, you can configure Source code repository and Repository push URL using the SSH protocol (for example git@github.com:WeblateOrg/weblate.git).

SSH repositories

The most frequently used method to access private repositories is based on SSH. Authorize the public Weblate SSH key (see Weblate SSH key) to access the upstream repository this way.

Warning

On GitHub, each key can only be used once, see GitHub repositories and Accessing repositories from Hosted Weblate.

Weblate also stores the host key fingerprint upon first connection, and fails to connect to the host should it be changed later (see Verifying SSH host keys).

In case adjustment is needed, do so from the Weblate admin interface:

Weblate SSH key

The Weblate public key is visible to all users browsing the About page.

Admins can generate or display the public key currently used by Weblate in the connection (from SSH keys) on the admin interface landing page.

Note

The corresponding private SSH key can not currently have a password, so make sure it is well protected.

Hint

Make a backup of the generated private Weblate SSH key.

Verifying SSH host keys

Weblate automatically stores the SSH host keys on first access and remembers them for further use.

In case you want to verify the key fingerprint before connecting to the repository, add the SSH host keys of the servers you are going to access in Add host key, from the same section of the admin interface. Enter the hostname you are going to access (e.g. gitlab.com), and press Submit. Verify its fingerprint matches the server you added.

The added keys with fingerprints are shown in the confirmation message:

GitHub repositories

Access via SSH is possible (see SSH repositories), but in case you need to access more than one repository, you will hit a GitHub limitation on allowed SSH key usage (since each key can be used only once).

In case the Push branch is not set, the project is forked and changes pushed through a fork. In case it is set, changes are pushed to the upstream repository and chosen branch.

For smaller deployments, use HTTPS authentication with a personal access token and your GitHub account, see Creating an access token for command-line use.

For bigger setups, it is usually better to create a dedicated user for Weblate, assign it the public SSH key generated in Weblate (see Weblate SSH key) and grant it access to all the repositories you want to translate. This approach is also used for Hosted Weblate, there is dedicated weblate user for that.

Weblate internal URLs

Share one repository setup between different components by referring to its placement as weblate://project/component in other(linked) components. This way linked components use the VCS repository configuration of the main(referenced) component.

Warning

Removing main component also removes linked components.

Weblate automatically adjusts the repository URL when creating a component if it finds a component with a matching repository setup. You can override this in the last step of the component configuration.

Reasons to use this:

Saves disk space on the server, the repository is stored just once.
Makes the updates faster, only one repository is updated.
There is just single exported repository with Weblate translations (see Git exporter).
Some addons can operate on multiple components sharing one repository, for example Squash Git commits.

HTTPS repositories

To access protected HTTPS repositories, include the username and password in the URL. Don’t worry, Weblate will strip this info when the URL is shown to users (if even allowed to see the repository URL at all).

For example the GitHub URL with authentication added might look like: https://user:your_access_token@github.com/WeblateOrg/weblate.git.

Note

If your username or password contains special characters, those have to be URL encoded, for example https://user%40example.com:%24password%23@bitbucket.org/….

Using proxy

If you need to access HTTP/HTTPS VCS repositories using a proxy server, configure the VCS to use it.

This can be done using the http_proxy, https_proxy, and all_proxy environment variables, (as described in the cURL documentation) or by enforcing it in the VCS configuration, for example:

git config --global http.proxy http://user:password@proxy.example.com:80

Note

The proxy configuration needs to be done under user running Weblate (see also Filesystem permissions) and with HOME=$DATA_DIR/home (see DATA_DIR), otherwise Git executed by Weblate will not use it.

Git

Hint

Weblate needs Git 2.12 or newer.

See also

See Accessing repositories for info on how to access different kinds of repositories.

Git with force push

This behaves exactly like Git itself, the only difference being that it always force pushes. This is intended only in the case of using a separate repository for translations.

Warning

Use with caution, as this easily leads to lost commits in your upstream repository.

Customizing Git configuration

Weblate invokes all VCS commands with HOME=$DATA_DIR/home (see DATA_DIR), therefore editing the user configuration needs to be done in DATA_DIR/home/.git.

Git remote helpers

You can also use Git remote helpers for additionally supporting other version control systems, but be prepared to debug problems this may lead to.

At this time, helpers for Bazaar and Mercurial are available within separate repositories on GitHub: git-remote-hg and git-remote-bzr. Download them manually and put somewhere in your search path (for example ~/bin). Make sure you have the corresponding version control systems installed.

Once you have these installed, such remotes can be used to specify a repository in Weblate.

To clone the gnuhello project from Launchpad using Bazaar:

bzr::lp:gnuhello

For the hello repository from selenic.com using Mercurial:

hg::http://selenic.com/repo/hello

Warning

The inconvenience of using Git remote helpers is for example with Mercurial, the remote helper sometimes creates a new tip when pushing changes back.

GitHub

New in version 2.3.

This adds a thin layer atop Git using the GitHub API to allow pushing translation changes as pull requests, instead of pushing directly to the repository.

Git pushes changes directly to a repository, while GitHub creates pull requests. The latter is not needed for merely accessing Git repositories.

See also

Pushing changes from Weblate

Pushing changes to GitHub as pull requests

If not wanting to push translations to a GitHub repository, they can be sent as either one or many pull requests instead.

You need to configure API credentials to make this work.

GitLab

New in version 3.9.

This just adds a thin layer atop Git using the GitLab API to allow pushing translation changes as merge requests instead of pushing directly to the repository.

There is no need to use this to access Git repositories, ordinary Git works the same, the only difference is how pushing to a repository is handled. With Git changes are pushed directly to the repository, while GitLab creates merge request.

See also

Pushing changes from Weblate

Pushing changes to GitLab as merge requests

If not wanting to push translations to a GitLab repository, they can be sent as either one or many merge requests instead.

You need to configure API credentials to make this work.

Pagure

New in version 4.3.2.

This just adds a thin layer atop Git using the Pagure API to allow pushing translation changes as merge requests instead of pushing directly to the repository.

See also

Pushing changes from Weblate

Pushing changes to Pagure as merge requests

If not wanting to push translations to a Pagure repository, they can be sent as either one or many merge requests instead.

You need to configure API credentials to make this work.

Gerrit

New in version 2.2.

Adds a thin layer atop Git using the git-review tool to allow pushing translation changes as Gerrit review requests, instead of pushing them directly to the repository.

The Gerrit documentation has the details on the configuration necessary to set up such repositories.

Mercurial

New in version 2.1.

Mercurial is another VCS you can use directly in Weblate.

Note

It should work with any Mercurial version, but there are sometimes incompatible changes to the command-line interface which breaks Weblate integration.

See also

See Accessing repositories for info on how to access different kinds of repositories.

Subversion

New in version 2.8.

Weblate uses git-svn to interact with subversion repositories. It is a Perl script that lets subversion be used by a Git client, enabling users to maintain a full clone of the internal repository and commit locally.

Note

Weblate tries to detect Subversion repository layout automatically - it supports both direct URLs for branch or repositories with standard layout (branches/, tags/ and trunk/). More info about this is to be found in the git-svn documentation. If your repository does not have a standard layout and you encounter errors, try including the branch name in the repository URL and leaving branch empty.

Changed in version 2.19: Before this, only repositories using the standard layout were supported.

Subversion credentials

Weblate expects you to have accepted the certificate up-front (and your credentials if needed). It will look to insert them into the DATA_DIR directory. Accept the certificate by using svn once with the $HOME environment variable set to the DATA_DIR:

# Use DATA_DIR as configured in Weblate settings.py, it is /app/data in the Docker
HOME=${DATA_DIR}/home svn co https://svn.example.com/example

See also

DATA_DIR

Local files

Git

Hint

Underneath, this uses Git. It requires Git installed and allows you to switch to using Git natively with full history of your translations.

New in version 3.8.

Weblate can also operate without a remote VCS. The initial translations are imported by uploading them. Later you can replace individual files by file upload, or add translation strings directly from Weblate (currently available only for monolingual translations).

In the background Weblate creates a Git repository for you and all changes are tracked in. In case you later decide to use a VCS to store the translations, you already have a repository within Weblate can base your integration on.

Weblate’s REST API

New in version 2.6: The REST API is available since Weblate 2.6.

The API is accessible on the /api/ URL and it is based on Django REST framework. You can use it directly or by Weblate Client.

Authentication and generic parameters

The public project API is available without authentication, though unauthenticated requests are heavily throttled (by default to 100 requests per day), so it is recommended to use authentication. The authentication uses a token, which you can get in your profile. Use it in the Authorization header:

ANY /

Generic request behaviour for the API, the headers, status codes and parameters here apply to all endpoints as well.

Query Parameters

format – Response format (overrides Accept). Possible values depends on REST framework setup, by default json and api are supported. The latter provides web browser interface for API.
page – Returns given page of paginated results (use next and previous fields in response to automate the navigation).

Request Headers

Accept – the response content type depends on Accept header
Authorization – optional token to authenticate as Authorization: Token YOUR-TOKEN

Response Headers

Content-Type – this depends on Accept header of request
Allow – list of allowed HTTP methods on object

Response JSON Object

detail (string) – verbose description of the result (for HTTP status codes other than 200 OK)
count (int) – total item count for object lists
next (string) – next page URL for object lists
previous (string) – previous page URL for object lists
results (array) – results for object lists
url (string) – URL to access this resource using API
web_url (string) – URL to access this resource using web browser

201 Created – when a new object was created successfully
204 No Content – when an object was deleted successfully
400 Bad Request – when form parameters are missing
403 Forbidden – when access is denied
429 Too Many Requests – when throttling is in place

Authentication tokens

Changed in version 4.10: Project scoped tokens were introduced in the 4.10 release.

Each user has his personal access token which can be obtained in the user profile. Newly generated user tokens have the wlu_ prefix.

It is possible to create project scoped tokens for API access to given project only. These tokens can be identified by the wlp_ prefix.

Authentication examples

API rate limiting

The API requests are rate limited; the default configuration limits it to 100 requests per day for anonymous users and 5000 requests per hour for authenticated users.

Rate limiting can be adjusted in the settings.py; see Throttling in Django REST framework documentation for more details how to configure it.

The status of rate limiting is reported in following headers:

`X-RateLimit-Limit`	Rate limiting limit of requests to perform
`X-RateLimit-Remaining`	Remaining limit of requests
`X-RateLimit-Reset`	Number of seconds until ratelimit window resets

Changed in version 4.1: Added ratelimiting status headers.

Weblate Client

New in version 2.7: There has been full wlc utility support ever since Weblate 2.7. If you are using an older version some incompatibilities with the API might occur.

Installation

The Weblate Client is shipped separately and includes the Python module. To use the commands below, you need to install wlc:

pip3 install wlc

Docker usage

The Weblate Client is also available as a Docker image.

The image is published on Docker Hub: https://hub.docker.com/r/weblate/wlc

Installing:

docker pull weblate/wlc

The Docker container uses Weblate’s default settings and connects to the API deployed in localhost. The API URL and API_KEY can be configured through the arguments accepted by Weblate.

The command to launch the container uses the following syntax:

docker run --rm weblate/wlc [WLC_ARGS]

Example:

docker run --rm weblate/wlc --url https://hosted.weblate.org/api/ list-projects

You might want to pass your Configuration files to the Docker container, the easiest approach is to add your current directory as /home/weblate volume:

docker run --volume $PWD:/home/weblate --rm weblate/wlc show

Getting started

The wlc configuration is stored in ~/.config/weblate (see Configuration files for other locations), please create it to match your environment:

[weblate]
url = https://hosted.weblate.org/api/

[keys]
https://hosted.weblate.org/api/ = APIKEY

You can then invoke commands on the default server:

wlc ls
wlc commit sandbox/hello-world

C:\Users\NAME\AppData\weblate.ini: New in version 1.6.

User configuration file on Windows.
~/.config/weblate: User configuration file
/etc/xdg/weblate: System wide configuration file

The program follows the XDG specification, so you can adjust placement of config files by environment variables XDG_CONFIG_HOME or XDG_CONFIG_DIRS. On Windows APPDATA directory is preferred location for the configuration file.

Following settings can be configured in the [weblate] section (you can customize this by --config-section):

key: API KEY to access Weblate.

url: API server URL, defaults to http://127.0.0.1:8000/api/.

translation: Path to the default translation - component or project.

The configuration file is an INI file, for example:

[weblate]
url = https://hosted.weblate.org/api/
key = APIKEY
translation = weblate/application

Additionally API keys can be stored in the [keys] section:

[keys]
https://hosted.weblate.org/api/ = APIKEY

This allows you to store keys in your personal settings, while using the .weblate configuration in the VCS repository so that wlc knows which server it should talk to.

Examples

Print current program version:

$ wlc version
version: 0.1

List all projects:

$ wlc list-projects
name: Hello
slug: hello
url: http://example.com/api/projects/hello/

You can also designate what project wlc should work on:

$ cat .weblate
[weblate]
url = https://hosted.weblate.org/api/
translation = weblate/application

$ wlc show
branch: main
file_format: po
source_language: en
filemask: weblate/locale/*/LC_MESSAGES/django.po
git_export: https://hosted.weblate.org/git/weblate/application/

slug: application
template:
url: https://hosted.weblate.org/api/components/weblate/application/
vcs: git
web_url: https://hosted.weblate.org/projects/weblate/application/

With this setup it is easy to commit pending changes in the current project:

$ wlc commit

Installing Weblate

Installing using Docker

With dockerized Weblate deployment you can get your personal Weblate instance up and running in seconds. All of Weblate’s dependencies are already included. PostgreSQL is set up as the default database.

Hardware requirements

Weblate should run on any contemporary hardware without problems, the following is the minimal configuration required to run Weblate on a single host (Weblate, database and webserver):

2 GB of RAM
2 CPU cores
1 GB of storage space

The more memory the better - it is used for caching on all levels (filesystem, database and Weblate).

Many concurrent users increases the amount of needed CPU cores. For hundreds of translation components at least 4 GB of RAM is recommended.

The typical database storage usage is around 300 MB per 1 million hosted words. Storage space needed for cloned repositories varies, but Weblate tries to keep their size minimal by doing shallow clones.

Note

Actual requirements for your installation of Weblate vary heavily based on the size of the translations managed in it.

Installation

The following examples assume you have a working Docker environment, with docker-compose installed. Please check the Docker documentation for instructions.

Clone the weblate-docker repo:

git clone https://github.com/WeblateOrg/docker-compose.git weblate-docker
cd weblate-docker

Create a docker-compose.override.yml file with your settings. See Docker environment variables for full list of environment variables.

version: '3'
services:
  weblate:
    ports:
      - 80:8080
    environment:
      WEBLATE_EMAIL_HOST: smtp.example.com
      WEBLATE_EMAIL_HOST_USER: user
      WEBLATE_EMAIL_HOST_PASSWORD: pass
      WEBLATE_SERVER_EMAIL: weblate@example.com
      WEBLATE_DEFAULT_FROM_EMAIL: weblate@example.com
      WEBLATE_SITE_DOMAIN: weblate.example.com
      WEBLATE_ADMIN_PASSWORD: password for the admin user
      WEBLATE_ADMIN_EMAIL: weblate.admin@example.com

Note

If WEBLATE_ADMIN_PASSWORD is not set, the admin user is created with a random password shown on first startup.

The provided example makes Weblate listen on port 80, edit the port mapping in the docker-compose.override.yml file to change it.

Start Weblate containers:
```
docker-compose up
```

Enjoy your Weblate deployment, it’s accessible on port 80 of the weblate container.

Changed in version 2.15-2: The setup has changed recently, priorly there was separate web server container, since 2.15-2 the web server is embedded in the Weblate container.

Changed in version 3.7.1-6: In July 2019 (starting with the 3.7.1-6 tag), the containers are not running as a root user. This has changed the exposed port from 80 to 8080.

Choosing Docker hub tag

You can use following tags on Docker hub, see https://hub.docker.com/r/weblate/weblate/tags/ for full list of available ones.

Tag name	Description	Use case
`latest`	Weblate stable release, matches latest tagged release	Rolling updates in a production environment
`<VERSION>-<PATCH>`	Weblate stable release	Well defined deploy in a production environment
`edge`	Weblate stable release with development changes in the Docker container (for example updated dependencies)	Rolling updates in a staging environment
`edge-<DATE>-<SHA>`	Weblate stable release with development changes in the Docker container (for example updated dependencies)	Well defined deploy in a staging environment
`bleeding`	Development version Weblate from Git	Rollling updates to test upcoming Weblate features
`bleeding-<DATE>-<SHA>`	Development version Weblate from Git	Well defined deploy to test upcoming Weblate features

Every image is tested by our CI before it gets published, so even the bleeding version should be quite safe to use.

Docker container with HTTPS support

Please see Installation for generic deployment instructions, this section only mentions differences compared to it.

Using own SSL certificates

New in version 3.8-3.

In case you have own SSL certificate you want to use, simply place the files into the Weblate data volume (see Docker container volumes):

ssl/fullchain.pem containing the certificate including any needed CA certificates
ssl/privkey.pem containing the private key

Both of these files must be owned by the same user as the one starting the docker container and have file mask set to 600 (readable and writable only by the owning user).

Additionally, Weblate container will now accept SSL connections on port 4443, you will want to include the port forwarding for HTTPS in docker compose override:

version: '3'
services:
  weblate:
    ports:
      - 80:8080
      - 443:4443

If you already host other sites on the same server, it is likely ports 80 and 443 are used by a reverse proxy, such as NGINX. To pass the HTTPS connection from NGINX to the docker container, you can use the following configuration:

server {
    listen 443;
    listen [::]:443;

    server_name <SITE_URL>;
    ssl_certificate /etc/letsencrypt/live/<SITE>/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/<SITE>/privkey.pem;

    location / {
            proxy_set_header HOST $host;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Host $server_name;
            proxy_pass https://127.0.0.1:<EXPOSED_DOCKER_PORT>;
    }
}

Replace <SITE_URL>, <SITE> and <EXPOSED_DOCKER_PORT> with actual values from your environment.

Automatic SSL certificates using Let’s Encrypt

In case you want to use Let’s Encrypt automatically generated SSL certificates on public installation, you need to add a reverse HTTPS proxy an additional Docker container, https-portal will be used for that. This is made use of in the docker-compose-https.yml file. Then create a docker-compose-https.override.yml file with your settings:

version: '3'
services:
  weblate:
    environment:
      WEBLATE_EMAIL_HOST: smtp.example.com
      WEBLATE_EMAIL_HOST_USER: user
      WEBLATE_EMAIL_HOST_PASSWORD: pass
      WEBLATE_SITE_DOMAIN: weblate.example.com
      WEBLATE_ADMIN_PASSWORD: password for admin user
  https-portal:
    environment:
      DOMAINS: 'weblate.example.com -> http://weblate:8080'

Whenever invoking docker-compose you need to pass both files to it, and then do:

docker-compose -f docker-compose-https.yml -f docker-compose-https.override.yml build
docker-compose -f docker-compose-https.yml -f docker-compose-https.override.yml up

Upgrading the Docker container

Usually it is good idea to only update the Weblate container and keep the PostgreSQL container at the version you have, as upgrading PostgreSQL is quite painful and in most cases does not bring many benefits.

Changed in version 4.10-1: Since Weblate 4.10-1, the Docker container uses Django 4.0 what requires PostgreSQL 10 or newer, please upgrade it prior to upgrading Weblate. See Upgrade from 4.9 to 4.10 for more details.

You can do this by sticking with the existing docker-compose and just pull the latest images and then restart:

# Fetch latest versions of the images
docker-compose pull
# Stop and destroy the containers
docker-compose down
# Spawn new containers in the background
docker-compose up -d
# Follow the logs during upgrade
docker-compose logs -f

The Weblate database should be automatically migrated on first startup, and there should be no need for additional manual actions.

Note

Upgrades across 3.0 are not supported by Weblate. If you are on 2.x series and want to upgrade to 3.x, first upgrade to the latest 3.0.1-x (at time of writing this it is the 3.0.1-7) image, which will do the migration and then continue upgrading to newer versions.

You might also want to update the docker-compose repository, though it’s not needed in most case. Please beware of PostgreSQL version changes in this case as it’s not straightforward to upgrade the database, see GitHub issue for more info.

Admin sign in

After container setup, you can sign in as admin user with password provided in WEBLATE_ADMIN_PASSWORD, or a random password generated on first start if that was not set.

To reset admin password, restart the container with WEBLATE_ADMIN_PASSWORD set to new password.

Number of processes and memory consumption

The number of worker processes for both uWSGI and Celery is determined automatically based on number of CPUs. This works well for most cloud virtual machines as these typically have few CPUs and good amount of memory.

In case you have a lot of CPU cores and hit out of memory issues, try reducing number of workers:

environment:
  WEBLATE_WORKERS: 2

You can also fine-tune individual worker categories:

environment:
  WEB_WORKERS: 4
  CELERY_MAIN_OPTIONS: --concurrency 2
  CELERY_NOTIFY_OPTIONS: --concurrency 1
  CELERY_TRANSLATE_OPTIONS: --concurrency 1

Scaling horizontally

New in version 4.6.

Warning

This feature is a technology preview.

You can run multiple Weblate containers to scale the service horizontally. The /app/data volume has to be shared by all containers, it is recommended to use cluster filesystem such as GlusterFS for this. The /app/cache volume should be separate for each container.

Each Weblate container has defined role using WEBLATE_SERVICE environment variable. Please follow carefully the documentation as some of the services should be running just once in the cluster and the ordering of the services matters as well.

You can find example setup in the docker-compose repo as docker-compose-split.yml.

Docker environment variables

Many of Weblate’s Configuration can be set in the Docker container using environment variables:

Generic settings

WEBLATE_DEBUG

Configures Django debug mode using DEBUG.

Example:

environment:
  WEBLATE_DEBUG: 1

See also

Disable debug mode

WEBLATE_LOGLEVEL: Configures the logging verbosity.

WEBLATE_SITE_TITLE: Changes the site-title shown in the header of all pages.

WEBLATE_SITE_DOMAIN: Configures the site domain. This parameter is required.

See also

Set correct site domain, SITE_DOMAIN

WEBLATE_ADMIN_NAME

WEBLATE_ADMIN_EMAIL

Configures the site-admin’s name and e-mail. It is used for both ADMINS setting and creating admin user (see WEBLATE_ADMIN_PASSWORD for more info on that).

Example:

environment:
  WEBLATE_ADMIN_NAME: Weblate admin
  WEBLATE_ADMIN_EMAIL: noreply@example.com

WEBLATE_ADMIN_PASSWORD

Sets the password for the admin user.

If not set and admin user does not exist, it is created with a random password shown on first container startup.
If not set and admin user exists, no action is performed.
If set the admin user is adjusted on every container startup to match WEBLATE_ADMIN_PASSWORD, WEBLATE_ADMIN_NAME and WEBLATE_ADMIN_EMAIL.

Warning

It might be a security risk to store password in the configuration file. Consider using this variable only for initial setup (or let Weblate generate random password on initial startup) or for password recovery.

WEBLATE_ADMIN_PASSWORD_FILE: Sets the path to a file containing the password for the admin user.

See also

WEBLATE_ADMIN_PASSWORD

WEBLATE_SERVER_EMAIL: The email address that error messages are sent from.

See also

SERVER_EMAIL, Configure e-mail sending

WEBLATE_DEFAULT_FROM_EMAIL: Configures the address for outgoing e-mails.

See also

DEFAULT_FROM_EMAIL, Configure e-mail sending

WEBLATE_CONTACT_FORM: Configures contact form behavior, see CONTACT_FORM.

WEBLATE_ALLOWED_HOSTS

Configures allowed HTTP hostnames using ALLOWED_HOSTS.

Defaults to * which allows all hostnames.

Example:

environment:
  WEBLATE_ALLOWED_HOSTS: weblate.example.com,example.com

WEBLATE_REGISTRATION_OPEN

Configures whether registrations are open by toggling REGISTRATION_OPEN.

Example:

environment:
  WEBLATE_REGISTRATION_OPEN: 0

WEBLATE_REGISTRATION_ALLOW_BACKENDS

Configure which authentication methods can be used to create new account via REGISTRATION_ALLOW_BACKENDS.

Example:

environment:
  WEBLATE_REGISTRATION_OPEN: 0
  WEBLATE_REGISTRATION_ALLOW_BACKENDS: azuread-oauth2,azuread-tenant-oauth2

WEBLATE_TIME_ZONE

Configures the used time zone in Weblate, see TIME_ZONE.

Note

To change the time zone of the Docker container itself, use the TZ environment variable.

Example:

environment:
  WEBLATE_TIME_ZONE: Europe/Prague

WEBLATE_ENABLE_HTTPS

Makes Weblate assume it is operated behind a reverse HTTPS proxy, it makes Weblate use HTTPS in e-mail and API links or set secure flags on cookies.

Hint

Please see ENABLE_HTTPS documentation for possible caveats.

Note

This does not make the Weblate container accept HTTPS connections, you need to configure that as well, see Docker container with HTTPS support for examples.

Example:

environment:
  WEBLATE_ENABLE_HTTPS: 1

WEBLATE_IP_PROXY_HEADER

Lets Weblate fetch the IP address from any given HTTP header. Use this when using a reverse proxy in front of the Weblate container.

Enables IP_BEHIND_REVERSE_PROXY and sets IP_PROXY_HEADER.

Note

The format must conform to Django’s expectations. Django transforms raw HTTP header names as follows:

converts all characters to uppercase
replaces any hyphens with underscores
prepends HTTP_ prefix

So X-Forwarded-For would be mapped to HTTP_X_FORWARDED_FOR.

Example:

environment:
  WEBLATE_IP_PROXY_HEADER: HTTP_X_FORWARDED_FOR

WEBLATE_SECURE_PROXY_SSL_HEADER

A tuple representing a HTTP header/value combination that signifies a request is secure. This is needed when Weblate is running behind a reverse proxy doing SSL termination which does not pass standard HTTPS headers.

Example:

environment:
  WEBLATE_SECURE_PROXY_SSL_HEADER: HTTP_X_FORWARDED_PROTO,https

See also

SECURE_PROXY_SSL_HEADER

WEBLATE_REQUIRE_LOGIN

Enables REQUIRE_LOGIN to enforce authentication on whole Weblate.

Docker container volumes

There are two volumes (data and cache) exported by the Weblate container. The other service containers (PostgreSQL or Redis) have their data volumes as well, but those are not covered by this document.

The data volume is used to store Weblate persistent data such as cloned repositories or to customize Weblate installation.

The placement of the Docker volume on host system depends on your Docker configuration, but usually it is stored in /var/lib/docker/volumes/weblate-docker_weblate-data/_data/ (the path consist of name of your docker-compose directory, container, and volume names). In the container it is mounted as /app/data.

The cache volume is mounted as /app/cache and is used to store static files. Its content is recreated on container startup and the volume can be mounted using ephemeral filesystem such as tmpfs.

When creating the volumes manually, the directories should be owned by UID 1000 as that is user used inside the container.

Docker volumes documentation

Further configuration customization

You can further customize Weblate installation in the data volume, see Docker container volumes.

Custom configuration files

You can additionally override the configuration in /app/data/settings-override.py (see Docker container volumes). This is executed at the end of built-in settings, after all environment settings are loaded, and you can adjust or override them.

Replacing logo and other static files

New in version 3.8-5.

The static files coming with Weblate can be overridden by placing into /app/data/python/customize/static (see Docker container volumes). For example creating /app/data/python/customize/static/favicon.ico will replace the favicon.

Hint

The files are copied to the corresponding location upon container startup, so a restart of Weblate is needed after changing the content of the volume.

Alternatively you can also include own module (see Customizing Weblate) and add it as separate volume to the Docker container, for example:

weblate:
  volumes:
    - weblate-data:/app/data
    - ./weblate_customization/weblate_customization:/app/data/python/weblate_customization
  environment:
    WEBLATE_ADD_APPS: weblate_customization

Adding own Python modules

New in version 3.8-5.

You can place own Python modules in /app/data/python/ (see Docker container volumes) and they can be then loaded by Weblate, most likely by using Custom configuration files.

Customizing Weblate

Installing on Debian and Ubuntu

Hardware requirements

Weblate should run on any contemporary hardware without problems, the following is the minimal configuration required to run Weblate on a single host (Weblate, database and webserver):

2 GB of RAM
2 CPU cores
1 GB of storage space

The more memory the better - it is used for caching on all levels (filesystem, database and Weblate).

Many concurrent users increases the amount of needed CPU cores. For hundreds of translation components at least 4 GB of RAM is recommended.

Note

Actual requirements for your installation of Weblate vary heavily based on the size of the translations managed in it.

Installation

Please check Optional dependencies for fine-tuning of optional dependencies.

Configuring Weblate

Note

Following steps assume virtualenv used by Weblate is active (what can be done by . ~/weblate-env/bin/activate). In case this is not true, you will have to specify full path to weblate command as ~/weblate-env/bin/weblate.

Copy the file ~/weblate-env/lib/python3.7/site-packages/weblate/settings_example.py to ~/weblate-env/lib/python3.7/site-packages/weblate/settings.py.
Adjust the values in the new settings.py file to your liking. You will need to provide at least the database credentials and Django secret key, but you will want more changes for production setup, see Adjusting configuration.
Create the database and its structure for Weblate (the example settings use PostgreSQL, check Database setup for Weblate for production ready setup):
```
weblate migrate
```
Create the administrator user account and copy the password it outputs to the clipboard, and also save it for later use:
```
weblate createadmin
```
Collect static files for web server (see Running server and Serving static files):
```
weblate collectstatic
```
Compress JavaScript and CSS files (optional, see Compressing client assets):
```
weblate compress
```
Start Celery workers. This is not necessary for development purposes, but strongly recommended otherwise. See Background tasks using Celery for more info:
```
~/weblate-env/lib/python3.7/site-packages/weblate/examples/celery start
```
Start the development server (see Running server for production setup):
```
weblate runserver
```

After installation

Congratulations, your Weblate server is now running and you can start using it.

You can now access Weblate on http://localhost:8000/.
Login with admin credentials obtained during installation or register with new users.
You can now run Weblate commands using weblate command when Weblate virtualenv is active, see Management commands.
You can stop the test server with Ctrl+C.
Review potential issues with your installation either on /manage/performance/ URL (see Management interface) or using weblate check --deploy, see Production setup.

Adding translation

Open the admin interface (http://localhost:8000/create/project/) and create the project you want to translate. See Project configuration for more details.

All you need to specify here is the project name and its website.
Create a component which is the real object for translation - it points to the VCS repository, and selects which files to translate. See Component configuration for more details.

The important fields here are: Component name, VCS repository address and mask for finding translatable files. Weblate supports a wide range of formats including gettext PO files, Android resource strings, iOS string properties, Java properties or Qt Linguist files, see Supported file formats for more details.
Once the above is completed (it can be lengthy process depending on the size of your VCS repository, and number of messages to translate), you can start translating.

Installing from sources

Please follow the installation instructions for your system first:
Grab the latest Weblate sources using Git (or download a tarball and unpack that):
```
git clone https://github.com/WeblateOrg/weblate.git weblate-src
```
Alternatively you can use released archives. You can download them from our website <https://weblate.org/>. Those downloads are cryptographically signed, please see Verifying release signatures.

Install current Weblate code into the virtualenv:

. ~/weblate-env/bin/activate
pip install -e weblate-src

Copy weblate/settings_example.py to weblate/settings.py.
Adjust the values in the new settings.py file to your liking. You will need to provide at least the database credentials and Django secret key, but you will want more changes for production setup, see Adjusting configuration.
Create the database used by Weblate, see Database setup for Weblate.
Build Django tables, static files and initial data (see Filling up the database and Serving static files):
```
weblate migrate
weblate collectstatic
weblate compress
weblate compilemessages
```
Note

This step should be repeated whenever you update the repository.

Installing on OpenShift

With the OpenShift Weblate template you can get your personal Weblate instance up and running in seconds. All of Weblate’s dependencies are already included. PostgreSQL is set up as the default database and persistent volume claims are used.

You can find the template at <https://github.com/WeblateOrg/openshift/>.

Installation

The following examples assume you have a working OpenShift v3.x environment, with oc client tool installed. Please check the OpenShift documentation for instructions.

The template.yml is suited for running all components in OpenShift. There is also template-external-postgresql.yml which does not start a PostgreSQL server and allows you to configure external PostgreSQL server.

Web Console

Copy the raw content from template.yml and import them into your project, then use the Create button in the OpenShift web console to create your application. The web console will prompt you for the values for all of the parameters used by the template.

CLI

To upload the Weblate template to your current project’s template library, pass the template.yml file with the following command:

$ oc create -f https://raw.githubusercontent.com/WeblateOrg/openshift/main/template.yml \
   -n <PROJECT>

The template is now available for selection using the web console or the CLI.

Parameters

The parameters that you can override are listed in the parameters section of the template. You can list them with the CLI by using the following command and specifying the file to be used:

$ oc process --parameters -f https://raw.githubusercontent.com/WeblateOrg/openshift/main/template.yml

# If the template is already uploaded
$ oc process --parameters -n <PROJECT> weblate

Provisioning

You can also use the CLI to process templates and use the configuration that is generated to create objects immediately.

$ oc process -f https://raw.githubusercontent.com/WeblateOrg/openshift/main/template.yml \
    -p APPLICATION_NAME=weblate \
    -p WEBLATE_VERSION=4.3.1-1 \
    -p WEBLATE_SITE_DOMAIN=weblate.app-openshift.example.com \
    -p POSTGRESQL_IMAGE=docker-registry.default.svc:5000/openshift/postgresql:9.6 \
    -p REDIS_IMAGE=docker-registry.default.svc:5000/openshift/redis:3.2 \
    | oc create -f

The Weblate instance should be available after successful migration and deployment at the specified WEBLATE_SITE_DOMAIN parameter.

After container setup, you can sign in as admin user with password provided in WEBLATE_ADMIN_PASSWORD, or a random password generated on first start if that was not set.

To reset admin password, restart the container with WEBLATE_ADMIN_PASSWORD set to new password in the respective Secret.

Eliminate

$ oc delete all -l app=<APPLICATION_NAME>
$ oc delete configmap -l app= <APPLICATION_NAME>
$ oc delete secret -l app=<APPLICATION_NAME>
# ATTTENTION! The following command is only optional and will permanently delete all of your data.
$ oc delete pvc -l app=<APPLICATION_NAME>

$ oc delete all -l app=weblate \
    && oc delete secret -l app=weblate \
    && oc delete configmap -l app=weblate \
    && oc delete pvc -l app=weblate

Configuration

By processing the template a respective ConfigMap will be created and which can be used to customize the Weblate image. The ConfigMap is directly mounted as environment variables and triggers a new deployment every time it is changed. For further configuration options, see Docker environment variables for full list of environment variables.

Installing on Kubernetes

Note

This guide is looking for contributors experienced with Kubernetes to cover the setup in more details.

With the Kubernetes Helm chart you can get your personal Weblate instance up and running in seconds. All of Weblate’s dependencies are already included. PostgreSQL is set up as the default database and persistent volume claims are used.

You can find the chart at <https://github.com/WeblateOrg/helm/> and it can be displayed at <https://artifacthub.io/packages/helm/weblate/weblate>.

Installation

helm repo add weblate https://helm.weblate.org
helm install my-release weblate/weblate

Configuration

For further configuration options, see Docker environment variables for full list of environment variables.

Depending on your setup and experience, choose an appropriate installation method for you:

Installing using Docker, recommended for production setups.
Virtualenv installation, recommended for production setups:
Installing from sources, recommended for development.
Installing on OpenShift
Installing on Kubernetes

Software requirements

Operating system

Weblate is known to work on Linux, FreeBSD and macOS. Other Unix like systems will most likely work too.

Weblate is not supported on Windows. But it may still work and patches are happily accepted.

Other services

Weblate is using other services for its operation. You will need at least following services running:

PostgreSQL database server, see Database setup for Weblate.
Redis server for cache and tasks queue, see Background tasks using Celery.
SMTP server for outgoing e-mail, see Configuring outgoing e-mail.

Python dependencies

pip install "Weblate[PHP,Fluent]"

Or you can install Weblate with all optional features:

pip install "Weblate[all]"

Or you can install Weblate without any optional features:

pip install Weblate

Database backend dependencies

Weblate supports PostgreSQL, MySQL and MariaDB, see Database setup for Weblate and backends documentation for more details.

Other system requirements

The following dependencies have to be installed on the system:

Git: https://git-scm.com/
Pango, Cairo and related header files and gir introspection data: https://cairographics.org/, https://pango.gnome.org/, see Pango and Cairo
git-review (optional for Gerrit support): https://pypi.org/project/git-review/
git-svn (optional for Subversion support): https://git-scm.com/docs/git-svn
tesseract and its data (optional for screenshots OCR): https://github.com/tesseract-ocr/tesseract
licensee (optional for detecting license when creating component): https://github.com/licensee/licensee

Build-time dependencies

To build some of the Python dependencies you might need to install their dependencies. This depends on how you install them, so please consult individual packages for documentation. You won’t need those if using prebuilt Wheels while installing using pip or when you use distribution packages.

Pango and Cairo

Changed in version 3.7.

Weblate uses Pango and Cairo for rendering bitmap widgets (see Promoting the translation) and rendering checks (see Managing fonts). To properly install Python bindings for those you need to install system libraries first - you need both Cairo and Pango, which in turn need GLib. All those should be installed with development files and GObject introspection data.

Verifying release signatures

Weblate release are cryptographically signed by the releasing developer. Currently this is Michal Čihař. Fingerprint of his PGP key is:

63CB 1DF1 EF12 CF2A C0EE 5A32 9C27 B313 42B7 511D

and you can get more identification information from <https://keybase.io/nijel>.

You should verify that the signature matches the archive you have downloaded. This way you can be sure that you are using the same code that was released. You should also verify the date of the signature to make sure that you downloaded the latest version.

Each archive is accompanied with .asc files which contain the PGP signature for it. Once you have both of them in the same folder, you can verify the signature:

$ gpg --verify Weblate-3.5.tar.xz.asc
gpg: assuming signed data in 'Weblate-3.5.tar.xz'
gpg: Signature made Ne 3. března 2019, 16:43:15 CET
gpg:                using RSA key 87E673AF83F6C3A0C344C8C3F4AA229D4D58C245
gpg: Can't check signature: public key not found

As you can see GPG complains that it does not know the public key. At this point you should do one of the following steps:

Use wkd to download the key:

The problem here is that anybody could issue the key with this name. You need to ensure that the key is actually owned by the mentioned person. The GNU Privacy Handbook covers this topic in the chapter Validating other keys on your public keyring. The most reliable method is to meet the developer in person and exchange key fingerprints, however you can also rely on the web of trust. This way you can trust the key transitively through signatures of others, who have met the developer in person.

Once the key is trusted, the warning will not occur:

Filesystem permissions

The Weblate process needs to be able to read and write to the directory where it keeps data - DATA_DIR. All files within this directory should be owned and writable by the user running all Weblate processes (typically WSGI and Celery, see Running server and Background tasks using Celery).

The default configuration places them in the same tree as the Weblate sources, however you might prefer to move these to a better location such as: /var/lib/weblate.

Weblate tries to create these directories automatically, but it will fail when it does not have permissions to do so.

You should also take care when running Management commands, as they should be ran under the same user as Weblate itself is running, otherwise permissions on some files might be wrong.

In the Docker container, all files in the /app/data volume have to be owned by weblate user inside the container (UID 1000).

Serving static files

Database setup for Weblate

It is recommended to run Weblate with a PostgreSQL database server.

PostgreSQL

PostgreSQL is usually the best choice for Django-based sites. It’s the reference database used for implementing Django database layer.

Note

Weblate uses trigram extension which has to be installed separately in some cases. Look for postgresql-contrib or a similarly named package.

See also

PostgreSQL notes

Creating a database in PostgreSQL

It is usually a good idea to run Weblate in a separate database, and separate user account:

# If PostgreSQL was not installed before, set the main password
sudo -u postgres psql postgres -c "\password postgres"

# Create a database user called "weblate"
sudo -u postgres createuser --superuser --pwprompt weblate

# Create the database "weblate" owned by "weblate"
sudo -u postgres createdb -E UTF8 -O weblate weblate

Hint

If you don’t want to make the Weblate user a superuser in PostgreSQL, you can omit that. In that case you will have to perform some of the migration steps manually as a PostgreSQL superuser in schema Weblate will use:

CREATE EXTENSION IF NOT EXISTS pg_trgm WITH SCHEMA weblate;

Configuring Weblate to use PostgreSQL

The settings.py snippet for PostgreSQL:

DATABASES = {
    "default": {
        # Database engine
        "ENGINE": "django.db.backends.postgresql",
        # Database name
        "NAME": "weblate",
        # Database user
        "USER": "weblate",
        # Name of role to alter to set parameters in PostgreSQL,
        # use in case role name is different than user used for authentication.
        # "ALTER_ROLE": "weblate",
        # Database password
        "PASSWORD": "password",
        # Set to empty string for localhost
        "HOST": "database.example.com",
        # Set to empty string for default
        "PORT": "",
    }
}

The database migration performs ALTER ROLE on database role used by Weblate. In most cases the name of the role matches username. In more complex setups the role name is different than username and you will get error about non-existing role during the database migration (psycopg2.errors.UndefinedObject: role "weblate@hostname" does not exist). This is known to happen with Azure Database for PostgreSQL, but it’s not limited to this environment. Please set ALTER_ROLE to change name of the role Weblate should alter during the database migration.

MySQL and MariaDB

Hint

Some Weblate features will perform better with PostgreSQL. This includes searching and translation memory, which both utilize full-text features in the database and PostgreSQL implementation is superior.

Weblate can be also used with MySQL or MariaDB, please see MySQL notes and MariaDB notes for caveats using Django with those. Because of the limitations it is recommended to use PostgreSQL for new installations.

Weblate requires MySQL at least 5.7.8 or MariaDB at least 10.2.7.

Following configuration is recommended for Weblate:

Use the utf8mb4 charset to allow representation of higher Unicode planes (for example emojis).
Configure the server with innodb_large_prefix to allow longer indices on text fields.
Set the isolation level to READ COMMITTED.
The SQL mode should be set to STRICT_TRANS_TABLES.

MySQL 8.x, MariaDB 10.5.x or newer have reasonable default configuration so that no server tweaking should be necessary and all what is needed can be configured on the client side.

Below is an example /etc/my.cnf.d/server.cnf for a server with 8 GB of RAM. These settings should be sufficient for most installs. MySQL and MariaDB have tunables that will increase the performance of your server that are considered not necessary unless you are planning on having large numbers of concurrent users accessing the system. See the various vendors documentation on those details.

It is absolutely critical to reduce issues when installing that the setting innodb_file_per_table is set properly and MySQL/MariaDB restarted before you start your Weblate install.

[mysqld]
character-set-server = utf8mb4
character-set-client = utf8mb4
collation-server = utf8mb4_unicode_ci

datadir=/var/lib/mysql

log-error=/var/log/mariadb/mariadb.log

innodb_large_prefix=1
innodb_file_format=Barracuda
innodb_file_per_table=1
innodb_buffer_pool_size=2G
sql_mode=STRICT_TRANS_TABLES

Hint

In case you are getting #1071 - Specified key was too long; max key length is 767 bytes error, please update your configuration to include the innodb settings above and restart your install.

Hint

In case you are getting #2006 - MySQL server has gone away error, configuring CONN_MAX_AGE might help.

Configuring Weblate to use MySQL/MariaDB

The settings.py snippet for MySQL and MariaDB:

DATABASES = {
    "default": {
        # Database engine
        "ENGINE": "django.db.backends.mysql",
        # Database name
        "NAME": "weblate",
        # Database user
        "USER": "weblate",
        # Database password
        "PASSWORD": "password",
        # Set to empty string for localhost
        "HOST": "127.0.0.1",
        # Set to empty string for default
        "PORT": "3306",
        # In case you wish to use additional
        # connection options
        "OPTIONS": {},
    }
}

You should also create the weblate user account in MySQL or MariaDB before you begin the install. Use the commands below to achieve that:

GRANT ALL ON weblate.* to 'weblate'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

Other configurations

Configuring outgoing e-mail

Weblate sends out e-mails on various occasions - for account activation and on various notifications configured by users. For this it needs access to an SMTP server.

The mail server setup is configured using these settings: EMAIL_HOST, EMAIL_HOST_PASSWORD, EMAIL_USE_TLS, EMAIL_USE_SSL, EMAIL_HOST_USER and EMAIL_PORT. Their names are quite self-explanatory, but you can find more info in the Django documentation.

Hint

In case you get error about not supported authentication (for example SMTP AUTH extension not supported by server), it is most likely caused by using insecure connection and server refuses to authenticate this way. Try enabling EMAIL_USE_TLS in such case.

Running behind reverse proxy

Several features in Weblate rely on being able to get client IP address. This includes Rate limiting, Spam protection or Audit log.

In default configuration Weblate parses IP address from REMOTE_ADDR which is set by the WSGI handler.

In case you are running a reverse proxy, this field will most likely contain its address. You need to configure Weblate to trust additional HTTP headers and parse the IP address from these. This can not be enabled by default as it would allow IP address spoofing for installations not using a reverse proxy. Enabling IP_BEHIND_REVERSE_PROXY might be enough for the most usual setups, but you might need to adjust IP_PROXY_HEADER and IP_PROXY_OFFSET as well.

HTTP proxy

Weblate does execute VCS commands and those accept proxy configuration from environment. The recommended approach is to define proxy settings in settings.py:

import os

os.environ["http_proxy"] = "http://proxy.example.com:8080"
os.environ["HTTPS_PROXY"] = "http://proxy.example.com:8080"

See also

Proxy Environment Variables

Adjusting configuration

See also

Sample configuration

Copy weblate/settings_example.py to weblate/settings.py and adjust it to match your setup. You will probably want to adjust the following options:

ADMINS

List of site administrators to receive notifications when something goes wrong, for example notifications on failed merges, or Django errors.

See also

ADMINS, Properly configure admins

ALLOWED_HOSTS

You need to set this to list the hosts your site is supposed to serve. For example:
ALLOWED_HOSTS = ["demo.weblate.org"]
Alternatively you can include wildcard:
ALLOWED_HOSTS = ["*"]
See also

ALLOWED_HOSTS, WEBLATE_ALLOWED_HOSTS, Allowed hosts setup

SESSION_ENGINE

Configure how your sessions will be stored. In case you keep the default database backend engine, you should schedule: weblate clearsessions to remove stale session data from the database.

If you are using Redis as cache (see Enable caching) it is recommended to use it for sessions as well:
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
See also

Configuring the session engine, SESSION_ENGINE

DATABASES

Connectivity to database server, please check Django’s documentation for more details.

See also

Database setup for Weblate, DATABASES, Databases

DEBUG

Disable this for any production server. With debug mode enabled, Django will show backtraces in case of error to users, when you disable it, errors will be sent per e-mail to ADMINS (see above).

Debug mode also slows down Weblate, as Django stores much more info internally in this case.

See also

DEBUG, Disable debug mode

DEFAULT_FROM_EMAIL

E-mail sender address for outgoing e-mail, for example registration e-mails.

See also

DEFAULT_FROM_EMAIL

SECRET_KEY

Key used by Django to sign some info in cookies, see Django secret key for more info.

See also

SECRET_KEY

SERVER_EMAIL

E-mail used as sender address for sending e-mails to the administrator, for example notifications on failed merges.

See also

SERVER_EMAIL

Filling up the database

After your configuration is ready, you can run weblate migrate to create the database structure. Now you should be able to create translation projects using the admin interface.

In case you want to run an installation non interactively, you can use weblate migrate --noinput, and then create an admin user using createadmin command.

Once you are done, you should also check the Performance report in the admin interface, which will give you hints of potential non optimal configuration on your site.

See also

Configuration, List of privileges

Production setup

For a production setup you should carry out adjustments described in the following sections. The most critical settings will trigger a warning, which is indicated by an exclamation mark in the top bar if signed in as a superuser:

It is also recommended to inspect checks triggered by Django (though you might not need to fix all of them):

weblate check --deploy

You can also review the very same checklist from the Management interface.

See also

Deployment checklist

Disable debug mode

Disable Django’s debug mode (DEBUG) by:

DEBUG = False

With debug mode on, Django stores all executed queries and shows users backtraces of errors, which is not desired in a production setup.

See also

Adjusting configuration

Properly configure admins

Set the correct admin addresses to the ADMINS setting to defining who will receive e-mails in case something goes wrong on the server, for example:

ADMINS = (("Your Name", "your_email@example.com"),)

See also

Adjusting configuration

Set correct site domain

Adjust site name and domain in the admin interface, otherwise links in RSS or registration e-mails will not work. This is configured using SITE_DOMAIN which should contain site domain name.

Changed in version 4.2: Prior to the 4.2 release the Django sites framework was used instead, please see The “sites” framework.

Correctly configure HTTPS

It is strongly recommended to run Weblate using the encrypted HTTPS protocol. After enabling it, you should set ENABLE_HTTPS in the settings:

ENABLE_HTTPS = True

Hint

You might want to set up HSTS as well, see SSL/HTTPS for more details.

Set properly SECURE_HSTS_SECONDS

If your site is served over SSL, you have to consider setting a value for SECURE_HSTS_SECONDS in the settings.py to enable HTTP Strict Transport Security. By default it’s set to 0 as shown below.

SECURE_HSTS_SECONDS = 0

If set to a non-zero integer value, the django.middleware.security.SecurityMiddleware sets the HTTP Strict Transport Security header on all responses that do not already have it.

Warning

Setting this incorrectly can irreversibly (for some time) break your site. Read the HTTP Strict Transport Security documentation first.

Use a powerful database engine

Please use PostgreSQL for a production environment, see Database setup for Weblate for more info.
Use adjacent location for running the database server, otherwise the networking performance or reliability might ruin your Weblate experience.
Check the database server performance or tweak its configuration, for example using PGTune.

Enable caching

If possible, use Redis from Django by adjusting the CACHES configuration variable, for example:

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/0",
        # If redis is running on same host as Weblate, you might
        # want to use unix sockets instead:
        # 'LOCATION': 'unix:///var/run/redis/redis.sock?db=0',
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "PARSER_CLASS": "redis.connection.HiredisParser",
        },
    }
}

Hint

In case you change Redis settings for the cache, you might need to adjust them for Celery as well, see Background tasks using Celery.

Avatar caching

In addition to caching of Django, Weblate performs caching of avatars. It is recommended to use a separate, file-backed cache for this purpose:

CACHES = {
    "default": {
        # Default caching backend setup, see above
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "unix:///var/run/redis/redis.sock?db=0",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "PARSER_CLASS": "redis.connection.HiredisParser",
        },
    },
    "avatar": {
        "BACKEND": "django.core.cache.backends.filebased.FileBasedCache",
        "LOCATION": os.path.join(DATA_DIR, "avatar-cache"),
        "TIMEOUT": 604800,
        "OPTIONS": {
            "MAX_ENTRIES": 1000,
        },
    },
}

Configure e-mail sending

Weblate needs to send out e-mails on several occasions, and these e-mails should have a correct sender address, please configure SERVER_EMAIL and DEFAULT_FROM_EMAIL to match your environment, for example:

SERVER_EMAIL = "admin@example.org"
DEFAULT_FROM_EMAIL = "weblate@example.org"

Note

To disable sending e-mails by Weblate set EMAIL_BACKEND to django.core.mail.backends.dummy.EmailBackend.

This will disable all e-mail delivery including registration or password reset e-mails.

Allowed hosts setup

Django requires ALLOWED_HOSTS to hold a list of domain names your site is allowed to serve, leaving it empty will block any requests.

In case this is not configured to match your HTTP server, you will get errors like Invalid HTTP_HOST header: '1.1.1.1'. You may need to add '1.1.1.1' to ALLOWED_HOSTS.

Hint

On Docker container, this is available as WEBLATE_ALLOWED_HOSTS.

Django secret key

The SECRET_KEY setting is used by Django to sign cookies, and you should really generate your own value rather than using the one from the example setup.

You can generate a new key using weblate/examples/generate-secret-key shipped with Weblate.

See also

SECRET_KEY

Home directory

Changed in version 2.1: This is no longer required, Weblate now stores all its data in DATA_DIR.

The home directory for the user running Weblate should exist and be writable by this user. This is especially needed if you want to use SSH to access private repositories, but Git might need to access this directory as well (depending on the Git version you use).

You can change the directory used by Weblate in settings.py, for example to set it to configuration directory under the Weblate tree:

os.environ["HOME"] = os.path.join(BASE_DIR, "configuration")

Note

On Linux, and other UNIX like systems, the path to user’s home directory is defined in /etc/passwd. Many distributions default to a non-writable directory for users used for serving web content (such as apache, www-data or wwwrun), so you either have to run Weblate under a different user, or change this setting.

See also

Accessing repositories

Template loading

It is recommended to use a cached template loader for Django. It caches parsed templates and avoids the need to do parsing with every single request. You can configure it using the following snippet (the loaders setting is important here):

TEMPLATES = [
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [
            os.path.join(BASE_DIR, "templates"),
        ],
        "OPTIONS": {
            "context_processors": [
                "django.contrib.auth.context_processors.auth",
                "django.template.context_processors.debug",
                "django.template.context_processors.i18n",
                "django.template.context_processors.request",
                "django.template.context_processors.csrf",
                "django.contrib.messages.context_processors.messages",
                "weblate.trans.context_processors.weblate_context",
            ],
            "loaders": [
                (
                    "django.template.loaders.cached.Loader",
                    [
                        "django.template.loaders.filesystem.Loader",
                        "django.template.loaders.app_directories.Loader",
                    ],
                ),
            ],
        },
    },
]

See also

django.template.loaders.cached.Loader

Running maintenance tasks

For optimal performance, it is good idea to run some maintenance tasks in the background. This is now automatically done by Background tasks using Celery and covers following tasks:

Configuration health check (hourly).
Committing pending changes (hourly), see Lazy commits and commit_pending.
Updating component alerts (daily).
Update remote branches (nightly), see AUTO_UPDATE.
Translation memory backup to JSON (daily), see dump_memory.
Fulltext and database maintenance tasks (daily and weekly tasks), see cleanuptrans.

Changed in version 3.2: Since version 3.2, the default way of executing these tasks is using Celery and Weblate already comes with proper configuration, see Background tasks using Celery.

System locales and encoding

The system locales should be configured to UTF-8 capable ones. On most Linux distributions this is the default setting. In case it is not the case on your system, please change locales to UTF-8 variant.

For example by editing /etc/default/locale and setting there LANG="C.UTF-8".

In some cases the individual services have separate configuration for locales. This varies between distribution and web servers, so check documentation of your web server packages for that.

Apache on Ubuntu uses /etc/apache2/envvars:

export LANG='en_US.UTF-8'
export LC_ALL='en_US.UTF-8'

Apache on CentOS uses /etc/sysconfig/httpd (or /opt/rh/httpd24/root/etc/sysconfig/httpd):

LANG='en_US.UTF-8'

Using custom certificate authority

Weblate does verify SSL certificates during HTTP requests. In case you are using custom certificate authority which is not trusted in default bundles, you will have to add its certificate as trusted.

The preferred approach is to do this at system level, please check your distro documentation for more details (for example on debian this can be done by placing the CA certificate into /usr/local/share/ca-certificates/ and running update-ca-certificates).

Once this is done, system tools will trust the certificate and this includes Git.

For Python code, you will need to configure requests to use system CA bundle instead of the one shipped with it. This can be achieved by placing following snippet to settings.py (the path is Debian specific):

import os

os.environ["REQUESTS_CA_BUNDLE"] = "/etc/ssl/certs/ca-certificates.crt"

Compressing client assets

Weblate comes with a bunch of JavaScript and CSS files. For performance reasons it is good to compress them before sending to a client. In default configuration this is done on the fly at cost of little overhead. On big installations, it is recommended to enable offline compression mode. This needs to be done in the configuration and the compression has to be triggered on every Weblate upgrade.

The configuration switch is simple by enabling django.conf.settings.COMPRESS_OFFLINE and configuring django.conf.settings.COMPRESS_OFFLINE_CONTEXT (the latter is already included in the example configuration):

COMPRESS_OFFLINE = True

On each deploy you need to compress the files to match current version:

weblate compress

Hint

The official Docker image has this feature already enabled.

Running server

Hint

In case you are not experienced with services described below, you might want to try Installing using Docker.

You will need several services to run Weblate, the recommended setup consists of:

Database server (see Database setup for Weblate)
Cache server (see Enable caching)
Frontend web server for static files and SSL termination (see Serving static files)
WSGI server for dynamic content (see Sample configuration for NGINX and uWSGI)
Celery for executing background tasks (see Background tasks using Celery)

Note

There are some dependencies between the services, for example cache and database should be running when starting up Celery or uwsgi processes.

In most cases, you will run all services on single (virtual) server, but in case your installation is heavy loaded, you can split up the services. The only limitation on this is that Celery and Wsgi servers need access to DATA_DIR.

Note

The WSGI process has to be executed under the same user the Celery process, otherwise files in the DATA_DIR will be stored with mixed ownership, leading to runtime issues.

Running web server

Running Weblate is not different from running any other Django based program. Django is usually executed as uWSGI or fcgi (see examples for different webservers below).

For testing purposes, you can use the built-in web server in Django:

weblate runserver

Warning

DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. See also Django documentation on runserver.

Hint

The Django built-in server serves static files only with DEBUG enabled as it is intended for development only. For production use, please see wsgi setups in Sample configuration for NGINX and uWSGI, Sample configuration for Apache, Sample configuration for Apache and Gunicorn, and Serving static files.

Serving static files

Changed in version 2.4: Prior to version 2.4, Weblate didn’t properly use the Django static files framework and the setup was more complex.

Django needs to collect its static files in a single directory. To do so, execute weblate collectstatic --noinput. This will copy the static files into a directory specified by the STATIC_ROOT setting (this defaults to a static directory inside DATA_DIR).

It is recommended to serve static files directly from your web server, you should use that for the following paths:

/static/: Serves static files for Weblate and the admin interface (from defined by STATIC_ROOT).
/media/: Used for user media uploads (e.g. screenshots).
/favicon.ico: Should be rewritten to rewrite a rule to serve /static/favicon.ico.

Content security policy

The default Weblate configuration enables weblate.middleware.SecurityMiddleware middleware which sets security related HTTP headers like Content-Security-Policy or X-XSS-Protection. These are by default set up to work with Weblate and its configuration, but this might need customization for your environment.

Sample configuration for NGINX and uWSGI

To run production webserver, use the wsgi wrapper installed with Weblate (in virtual env case it is installed as ~/weblate-env/lib/python3.7/site-packages/weblate/wsgi.py). Don’t forget to set the Python search path to your virtualenv as well (for example using virtualenv = /home/user/weblate-env in uWSGI).

The following configuration runs Weblate as uWSGI under the NGINX webserver.

Configuration for NGINX (also available as weblate/examples/weblate.nginx.conf):

# This example assumes Weblate is installed in virtualenv in /home/weblate/weblate-env
# and DATA_DIR is set to /home/weblate/data, please adjust paths to match your setup.
server {
    listen 80;
    server_name weblate;
    # Not used
    root /var/www/html;

    location ~ ^/favicon.ico$ {
        # DATA_DIR/static/favicon.ico
        alias /home/weblate/data/static/favicon.ico;
        expires 30d;
    }

    location /static/ {
        # DATA_DIR/static/

Sample configuration for Apache

It is recommended to use prefork MPM when using WSGI with Weblate.

The following configuration runs Weblate as WSGI, you need to have enabled mod_wsgi (available as weblate/examples/apache.conf):

#
# VirtualHost for Weblate
#
# This example assumes Weblate is installed in virtualenv in /home/weblate/weblate-env
# and DATA_DIR is set to /home/weblate/data, please adjust paths to match your setup.
#
<VirtualHost *:80>
    ServerAdmin admin@weblate.example.org
    ServerName weblate.example.org

    # DATA_DIR/static/favicon.ico
    Alias /favicon.ico /home/weblate/data/static/favicon.ico

    # DATA_DIR/static/
    Alias /static/ /home/weblate/data/static/
    <Directory /home/weblate/data/static/>
        Require all granted
    </Directory>

    # DATA_DIR/media/
    Alias /media/ /home/weblate/data/media/
    <Directory /home/weblate/data/media/>
        Require all granted
    </Directory>

    # Path to your Weblate virtualenv
    WSGIDaemonProcess weblate python-home=/home/weblate/weblate-env user=weblate
    WSGIProcessGroup weblate
    WSGIApplicationGroup %{GLOBAL}

    WSGIScriptAlias / /home/weblate/weblate-env/lib/python3.7/site-packages/weblate/wsgi.py process-group=weblate request-timeout=600
    WSGIPassAuthorization On

    <Directory /home/weblate/weblate-env/lib/python3.7/site-packages/weblate/>
        <Files wsgi.py>
        Require all granted
        </Files>
    </Directory>

</VirtualHost>

Note

Weblate requires Python 3, so please make sure you are running Python 3 variant of the modwsgi. Usually it is available as a separate package, for example libapache2-mod-wsgi-py3.

Sample configuration for Apache and Gunicorn

The following configuration runs Weblate in Gunicorn and Apache 2.4 (available as weblate/examples/apache.gunicorn.conf):

#
# VirtualHost for Weblate using gunicorn on localhost:8000
#
# This example assumes Weblate is installed in virtualenv in /home/weblate/weblate-env
# and DATA_DIR is set to /home/weblate/data, please adjust paths to match your setup.
#
<VirtualHost *:443>
    ServerAdmin admin@weblate.example.org

Running Weblate under path

New in version 1.3.

It is recommended to use prefork MPM when using WSGI with Weblate.

A sample Apache configuration to serve Weblate under /weblate. Again using mod_wsgi (also available as weblate/examples/apache-path.conf):

#
# VirtualHost for Weblate, running under /weblate path
#
# This example assumes Weblate is installed in virtualenv in /home/weblate/weblate-env
# and DATA_DIR is set to /home/weblate/data, please adjust paths to match your setup.
#
<VirtualHost *:80>
    ServerAdmin admin@weblate.example.org
    ServerName weblate.example.org

    # DATA_DIR/static/favicon.ico
    Alias /weblate/favicon.ico /home/weblate/data/static/favicon.ico

    # DATA_DIR/static/
    Alias /weblate/static/ /home/weblate/data/static/
    <Directory /home/weblate/data/static/>
        Require all granted
    </Directory>

    # DATA_DIR/media/
    Alias /weblate/media/ /home/weblate/data/media/
    <Directory /home/weblate/data/media/>
        Require all granted
    </Directory>

    # Path to your Weblate virtualenv
    WSGIDaemonProcess weblate python-home=/home/weblate/weblate-env user=weblate
    WSGIProcessGroup weblate
    WSGIApplicationGroup %{GLOBAL}

    WSGIScriptAlias /weblate /home/weblate/weblate-env/lib/python3.7/site-packages/weblate/wsgi.py process-group=weblate request-timeout=600
    WSGIPassAuthorization On

    <Directory /home/weblate/weblate-env/lib/python3.7/site-packages/weblate/>
        <Files wsgi.py>
        Require all granted
        </Files>
    </Directory>

</VirtualHost>

Additionally, you will have to adjust weblate/settings.py:

URL_PREFIX = "/weblate"

Background tasks using Celery

New in version 3.2.

Weblate uses Celery to execute regular and background tasks. You are supposed to run a Celery service that will execute these. For example, it is responsible for handling following operations (this list is not complete):

Receiving webhooks from external services (see Notification hooks).
Running regular maintenance tasks such as backups, cleanups, daily add-ons, or updates (see Backing up and moving Weblate, BACKGROUND_TASKS, Add-ons).
Running Automatic translation.
Sending digest notifications.
Offloading expensive operations from the wsgi process.
Committing pending changes (see Lazy commits).

A typical setup using Redis as a backend looks like this:

CELERY_TASK_ALWAYS_EAGER = False
CELERY_BROKER_URL = "redis://localhost:6379"
CELERY_RESULT_BACKEND = CELERY_BROKER_URL

See also

Redis broker configuration in Celery

You should also start the Celery worker to process the tasks and start scheduled tasks, this can be done directly on the command-line (which is mostly useful when debugging or developing):

./weblate/examples/celery start
./weblate/examples/celery stop

Note

The Celery process has to be executed under the same user as the WSGI process, otherwise files in the DATA_DIR will be stored with mixed ownership, leading to runtime issues.

Executing Celery tasks in the wsgi using eager mode

Note

This will have severe performance impact on the web interface, and will break features depending on regular trigger (for example committing pending changes, digest notifications, or backups).

For development, you might want to use eager configuration, which does process all tasks in place:

CELERY_TASK_ALWAYS_EAGER = True
CELERY_BROKER_URL = "memory://"
CELERY_TASK_EAGER_PROPAGATES = True

Running Celery as system service

Most likely you will want to run Celery as a daemon and that is covered by Daemonization. For the most common Linux setup using systemd, you can use the example files shipped in the examples folder listed below.

Systemd unit to be placed as /etc/systemd/system/celery-weblate.service:

[Unit]
Description=Celery Service (Weblate)
After=network.target

[Service]
Type=forking
User=weblate
Group=weblate
EnvironmentFile=/etc/default/celery-weblate
WorkingDirectory=/home/weblate
RuntimeDirectory=celery
RuntimeDirectoryPreserve=restart
LogsDirectory=celery
ExecStart=/bin/sh -c '${CELERY_BIN} multi start ${CELERYD_NODES} \
  -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE} \
  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'
ExecStop=/bin/sh -c '${CELERY_BIN} multi stopwait ${CELERYD_NODES} \
  --pidfile=${CELERYD_PID_FILE}'
ExecReload=/bin/sh -c '${CELERY_BIN} multi restart ${CELERYD_NODES} \
  -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE} \
  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'

[Install]
WantedBy=multi-user.target

Environment configuration to be placed as /etc/default/celery-weblate:

# Name of nodes to start
CELERYD_NODES="celery notify memory backup translate"

# Absolute or relative path to the 'celery' command:
CELERY_BIN="/home/weblate/weblate-env/bin/celery"

# App instance to use
# comment out this line if you don't use an app
CELERY_APP="weblate.utils"

# Extra command-line arguments to the worker,
# increase concurency if you get weblate.E019
CELERYD_OPTS="--beat:celery --queues:celery=celery --prefetch-multiplier:celery=4 \
    --queues:notify=notify --prefetch-multiplier:notify=10 \
    --queues:memory=memory --prefetch-multiplier:memory=10 \
    --queues:translate=translate --prefetch-multiplier:translate=4 \
    --concurrency:backup=1 --queues:backup=backup  --prefetch-multiplier:backup=2"

# Logging configuration
# - %n will be replaced with the first part of the nodename.
# - %I will be replaced with the current child process index
#   and is important when using the prefork pool to avoid race conditions.
CELERYD_PID_FILE="/run/celery/weblate-%n.pid"
CELERYD_LOG_FILE="/var/log/celery/weblate-%n%I.log"
CELERYD_LOG_LEVEL="INFO"

Additional configuration to rotate Celery logs using logrotate to be placed as /etc/logrotate.d/celery:

/var/log/celery/*.log {
        weekly
        missingok
        rotate 12
        compress
        notifempty
}

Periodic tasks using Celery beat

Weblate comes with built-in setup for scheduled tasks. You can however define additional tasks in settings.py, for example see Lazy commits.

The tasks are supposed to be executed by Celery beats daemon. In case it is not working properly, it might not be running or its database was corrupted. Check the Celery startup logs in such case to figure out root cause.

Monitoring Celery status

You can find current length of the Celery task queues in the Management interface or you can use celery_queues on the command-line. In case the queue will get too long, you will also get configuration error in the admin interface.

Warning

The Celery errors are by default only logged into Celery log and are not visible to user. In case you want to have overview on such failures, it is recommended to configure Collecting error reports.

Monitoring Weblate

Weblate provides the /healthz/ URL to be used in simple health checks, for example using Kubernetes. The Docker container has built-in health check using this URL.

For monitoring metrics of Weblate you can use GET /api/metrics/ API endpoint.

Weblate plugin for Munin

Collecting error reports

Weblate, as any other software, can fail. In order to collect useful failure states we recommend to use third party services to collect such information. This is especially useful in case of failing Celery tasks, which would otherwise only report error to the logs and you won’t get notified on them. Weblate has support for the following services:

Sentry

Weblate has built-in support for Sentry. To use it, it’s enough to set SENTRY_DSN in the settings.py:

SENTRY_DSN = "https://id@your.sentry.example.com/"

Rollbar

Weblate has built-in support for Rollbar. To use it, it’s enough to follow instructions for Rollbar notifier for Python.

In short, you need to adjust settings.py:

# Add rollbar as last middleware:
MIDDLEWARE = [
    # … other middleware classes …
    "rollbar.contrib.django.middleware.RollbarNotifierMiddleware",
]

# Configure client access
ROLLBAR = {
    "access_token": "POST_SERVER_ITEM_ACCESS_TOKEN",
    "client_token": "POST_CLIENT_ITEM_ACCESS_TOKEN",
    "environment": "development" if DEBUG else "production",
    "branch": "main",
    "root": "/absolute/path/to/code/root",
}

Everything else is integrated automatically, you will now collect both server and client side errors.

Migrating Weblate to another server

Migrating Weblate to another server should be pretty easy, however it stores data in few locations which you should migrate carefully. The best approach is to stop Weblate for the migration.

Migrating database

Depending on your database backend, you might have several options to migrate the database. The most straightforward one is to dump the database on one server and import it on the new one. Alternatively you can use replication in case your database supports it.

The best approach is to use database native tools, as they are usually the most effective (e.g. mysqldump or pg_dump). If you want to migrate between different databases, the only option might be to use Django management to dump and import the database:

# Export current data
weblate dumpdata > /tmp/weblate.dump
# Import dump
weblate loaddata /tmp/weblate.dump

Migrating VCS repositories

The VCS repositories stored under DATA_DIR need to be migrated as well. You can simply copy them or use rsync to do the migration more effectively.

Other notes

Don’t forget to move other services Weblate might have been using like Redis, Cron jobs or custom authentication backends.

Weblate deployments

Weblate can be easily installed in your cloud. Please find detailed guide for your platform:

Third-party deployments for Weblate

Note

Following deployments are not developed or supported by Weblate team. Parts of the setup might vary from what is described in this documentation.

Bitnami Weblate stack

Bitnami provides a Weblate stack for many platforms at <https://bitnami.com/stack/weblate>. The setup will be adjusted during installation, see <https://bitnami.com/stack/weblate/README.txt> for more documentation.

Weblate Cloudron Package

Cloudron is a platform for self-hosting web applications. Weblate installed with Cloudron will be automatically kept up-to-date. The package is maintained by the Cloudron team at their Weblate package repo.

Weblate in YunoHost

The self-hosting project YunoHost provides a package for Weblate. Once you have your YunoHost installation, you may install Weblate as any other application. It will provide you with a fully working stack with backup and restoration, but you may still have to edit your settings file for specific usages.

You may use your administration interface, or this button (it will bring you to your server):

It also is possible to use the command-line interface:

yunohost app install https://github.com/YunoHost-Apps/weblate_ynh

Upgrading Weblate

Docker image upgrades

The official Docker image (see Installing using Docker) has all Weblate upgrade steps integrated. There are typically no manual steps needed besides pulling latest version.

See also

Upgrading the Docker container

Generic upgrade instructions

Before upgrading, please check the current Software requirements as they might have changed. Once all requirements are installed or updated, please adjust your settings.py to match changes in the configuration (consult settings_example.py for correct values).

Always check Version specific instructions before upgrade. In case you are skipping some versions, please follow instructions for all versions you are skipping in the upgrade. Sometimes it’s better to upgrade to some intermediate version to ensure a smooth migration. Upgrading across multiple releases should work, but is not as well tested as single version upgrades.

Note

It is recommended to perform a full database backup prior to upgrade so that you can roll back the database in case upgrade fails, see Backing up and moving Weblate.

Stop wsgi and Celery processes. The upgrade can perform incompatible changes in the database, so it is always safer to avoid old processes running while upgrading.

Upgrade Weblate code.

For pip installs it can be achieved by:

pip install -U "Weblate[all]"

If you don’t want to install all of the optional dependencies do:

pip install -U Weblate

With Git checkout you need to fetch new source code and update your installation:

cd weblate-src
git pull
# Update Weblate inside your virtualenv
. ~/weblate-env/bin/pip install -e .
# Install dependencies directly when not using virtualenv
pip install --upgrade -r requirements.txt
# Install optional dependencies directly when not using virtualenv
pip install --upgrade -r requirements-optional.txt

New Weblate release might have new Optional dependencies, please check if they cover features you want.
Upgrade configuration file, refer to settings_example.py or Version specific instructions for needed steps.
Upgrade database structure:
```
weblate migrate --noinput
```
Collect updated static files (see Running server and Serving static files):
```
weblate collectstatic --noinput --clear
```
Compress JavaScript and CSS files (optional, see Compressing client assets):
```
weblate compress
```
If you are running version from Git, you should also regenerate locale files every time you are upgrading. You can do this by invoking:
```
weblate compilemessages
```
Verify that your setup is sane (see also Production setup):
```
weblate check --deploy
```
Restart Celery worker (see Background tasks using Celery).

Upgrading from Python 2 to Python 3

Weblate no longer supports Python older than 3.6. In case you are still running on older version, please perform migration to Python 3 first on existing version and upgrade later. See Upgrading from Python 2 to Python 3 in the Weblate 3.11.1 documentation.

Migrating from other databases to PostgreSQL

If you are running Weblate on other dabatase than PostgreSQL, you should consider migrating to PostgreSQL as Weblate performs best with it. The following steps will guide you in migrating your data between the databases. Please remember to stop both web and Celery servers prior to the migration, otherwise you might end up with inconsistent data.

Creating a database in PostgreSQL

It is usually a good idea to run Weblate in a separate database, and separate user account:

# If PostgreSQL was not installed before, set the main password
sudo -u postgres psql postgres -c "\password postgres"

# Create a database user called "weblate"
sudo -u postgres createuser -D -P weblate

# Create the database "weblate" owned by "weblate"
sudo -u postgres createdb -E UTF8 -O weblate weblate

Migrating using Django JSON dumps

The simplest approach for migration is to utilize Django JSON dumps. This works well for smaller installations. On bigger sites you might want to use pgloader instead, see Migrating to PostgreSQL using pgloader.

Add PostgreSQL as additional database connection to the settings.py:

DATABASES = {
    "default": {
        # Database engine
        "ENGINE": "django.db.backends.mysql",
        # Database name
        "NAME": "weblate",
        # Database user
        "USER": "weblate",
        # Database password
        "PASSWORD": "password",
        # Set to empty string for localhost
        "HOST": "database.example.com",
        # Set to empty string for default
        "PORT": "",
        # Additional database options
        "OPTIONS": {

            "charset": "utf8mb4",
            # Change connection timeout in case you get MySQL gone away error:

        # Set to empty string for localhost
        "HOST": "database.example.com",
        # Set to empty string for default
        "PORT": "",
    },
}

Run migrations and drop any data inserted into the tables:

weblate migrate --database=postgresql
weblate sqlflush --database=postgresql | weblate dbshell --database=postgresql

Dump legacy database and import to PostgreSQL

weblate dumpdata --all --output weblate.json
weblate loaddata weblate.json --database=postgresql

Adjust DATABASES to use just PostgreSQL database as default, remove legacy connection.

Weblate should be now ready to run from the PostgreSQL database.

Migrating to PostgreSQL using pgloader

The pgloader is a generic migration tool to migrate data to PostgreSQL. You can use it to migrate Weblate database.

Adjust your settings.py to use PostgreSQL as a database.

Migrate the schema in the PostgreSQL database:

weblate migrate
weblate sqlflush | weblate dbshell

Run the pgloader to transfer the data. The following script can be used to migrate the database, but you might want to learn more about pgloader to understand what it does and tweak it to match your setup:

LOAD DATABASE
     FROM      mysql://weblate:password@localhost/weblate
     INTO postgresql://weblate:password@localhost/weblate

WITH include no drop, truncate, create no tables, create no indexes, no foreign keys, disable triggers, reset sequences, data only

ALTER SCHEMA 'weblate' RENAME TO 'public'
;

Migrating from Pootle

As Weblate was originally written as replacement from Pootle, it is supported to migrate user accounts from Pootle. You can dump the users from Pootle and import them using importusers.

Backing up and moving Weblate

Automated backup using BorgBackup

New in version 3.9.

Weblate has built-in support for creating service backups using BorgBackup. Borg creates space-effective encrypted backups which can be safely stored in the cloud. The backups can be controlled in the management interface from the Backups tab.

Changed in version 4.4.1: Both PostgreSQL and MySQL/MariaDB databases are included in the automated backups.

The backups using Borg are incremental and Weblate is configured to keep following backups:

Daily backups for 14 days back
Weekly backups for 8 weeks back
Monthly backups for 6 months back

Borg encryption key

BorgBackup creates encrypted backups and you wouldn’t be able to restore them without the passphrase. The passphrase is generated when adding a new backup service and you should copy it and keep it in a secure place.

If you are using Weblate provisioned backup storage, please backup your private SSH key too, as it’s used to access your backups.

See also

borg init

Customizing backup

The database backup can be configured via DATABASE_BACKUP.
The backup creation can be customized using BORG_EXTRA_ARGS.

Weblate provisioned backup storage

The easiest way of backing up your Weblate instance is purchasing the backup service at weblate.org. This is how you get it running:

Purchase the Backup service on https://weblate.org/support/#backup.
Enter the obtained key in the management interface, see Integrating support.
Weblate connects to the cloud service and obtains access info for the backups.
Turn on the new backup configuration from the Backups tab.
Backup your Borg credentials to be able to restore the backups, see Borg encryption key.

Hint

The manual step of turning everything on is there for your safety. Without your consent no data is sent to the backup repository obtained through the registration process.

Using custom backup storage

You can also use your own storage for the backups. SSH can be used to store backups in the remote destination, the target server needs to have BorgBackup installed.

See also

General in the Borg documentation

Local filesystem

It is recommended to specify the absolute path for the local backup, for example /path/to/backup. The directory has to be writable by the user running Weblate (see Filesystem permissions). If it doesn’t exist, Weblate attempts to create it but needs the appropriate permissions to do so.

Hint

When running Weblate in Docker, please ensure the backup location is exposed as a volume from the Weblate container. Otherwise the backups will be discarded by Docker upon restarting the container it is in.

One option is to place backups into an existing volume, for example /app/data/borgbackup. This is an existing volume in the container.

You can also add a new container for the backups in the Docker Compose file for example by using /borgbackup:

services:
  weblate:
    volumes:
      - /home/weblate/data:/app/data
      - /home/weblate/borgbackup:/borgbackup

The directory where backups will be stored have to be owned by UID 1000, otherwise Weblate won’t be able to write the backups there.

Remote backups

For creating remote backups, you will have to install BorgBackup onto another server that’s accessible for your Weblate deployment via SSH using the Weblate SSH key:

Prepare a server where your backups will be stored.
Install the SSH server on it (you will get it by default with most Linux distributions).
Install BorgBackup on that server; most Linux distributions have packages available (see Installation).
Choose an existing user or create a new user that will be used for backing up.
Add Weblate SSH key to the user so that Weblate can SSH to the server without a password (see Weblate SSH key).
Configure the backup location in Weblate as user@host:/path/to/backups or ssh://user@host:port/path/to/backups.

Hint

Weblate provisioned backup storage provides you automated remote backups without any effort.

See also

Weblate SSH key, General

Restoring from BorgBackup

Restore access to your backup repository and prepare your backup passphrase.
List all the backups on the server using borg list REPOSITORY.
Restore the desired backup to the current directory using borg extract REPOSITORY::ARCHIVE.
Restore the database from the SQL dump placed in the backup directory in the Weblate data dir (see Dumped data for backups).
Copy the Weblate configuration (backups/settings.py, see Dumped data for backups) to the correct location, see Adjusting configuration.

When using Docker container, the settings file is already included in the container and you should restore the original environment variables. The environment.yml file might help you with this (see Dumped data for backups).
Copy the whole restored data dir to the location configured by DATA_DIR.

When using Docker container place the data into the data volume, see Docker container volumes.

Please make sure the files have correct ownership and permissions, see Filesystem permissions.

The Borg session might look like this:

$ borg list /tmp/xxx
Enter passphrase for key /tmp/xxx:
2019-09-26T14:56:08                  Thu, 2019-09-26 14:56:08 [de0e0f13643635d5090e9896bdaceb92a023050749ad3f3350e788f1a65576a5]
$ borg extract /tmp/xxx::2019-09-26T14:56:08
Enter passphrase for key /tmp/xxx:

See also

borg list, borg extract

Manual backup

Depending on what you want to save, back up the type of data Weblate stores in each respective place.

Hint

If you are doing the manual backups, you might want to silence Weblate’s warning about a lack of backups by adding weblate.I028 to SILENCED_SYSTEM_CHECKS in settings.py or WEBLATE_SILENCED_SYSTEM_CHECKS for Docker.

SILENCED_SYSTEM_CHECKS.append("weblate.I028")

Database

The actual storage location depends on your database setup.

Hint

The database is the most important storage. Set up regular backups of your database. Without the database, all the translations are gone.

Native database backup

The recommended approach is to save a dump of the database using database-native tools such as pg_dump or mysqldump. It usually performs better than Django backup, and it restores complete tables with all their data.

You can restore this backup in a newer Weblate release, it will perform all the necessary migrations when running in migrate. Please consult Upgrading Weblate on more detailed info on how to upgrade between versions.

Django database backup

Alternatively, you can back up your database using Django’s dumpdata command. That way the backup is database agnostic and can be used in case you want to change the database backend.

Prior to restoring the database you need to be running exactly the same Weblate version the backup was made on. This is necessary as the database structure does change between releases and you would end up corrupting the data in some way. After installing the same version, run all database migrations using migrate.

Afterwards some entries will already be created in the database and you will have them in the database backup as well. The recommended approach is to delete such entries manually using the management shell (see Invoking management commands):

weblate shell
>>> from weblate.auth.models import User
>>> User.objects.get(username='anonymous').delete()

Files

If you have enough backup space, simply back up the whole DATA_DIR. This is a safe bet even if it includes some files you don’t want. The following sections describe what you should back up and what you can skip in detail.

Dumped data for backups

Changed in version 4.7: The environment dump was added as environment.yml to help in restoring in the Docker environments.

Stored in DATA_DIR /backups.

Weblate dumps various data here, and you can include these files for more complete backups. The files are updated daily (requires a running Celery beats server, see Background tasks using Celery). Currently, this includes:

Weblate settings as settings.py (there is also expanded version in settings-expanded.py).
PostgreSQL database backup as database.sql.
Environment dump as environment.yml.

The database backups are saved as plain text by default, but they can also be compressed or entirely skipped using DATABASE_BACKUP.

To restore the database backup load it using dabase tools, for example:

psql --file=database.sql weblate

Version control repositories

Stored in DATA_DIR /vcs.

The version control repositories contain a copy of your upstream repositories with Weblate changes. If you have Push on commit enabled for all your translation components, all Weblate changes are included upstream. No need to back up the repositories on the Weblate side as they can be cloned again from the upstream location(s) with no data loss.

SSH and GPG keys

Stored in DATA_DIR /ssh and DATA_DIR /home.

If you are using SSH or GPG keys generated by Weblate, you should back up these locations. Otherwise you will lose the private keys and you will have to regenerate new ones.

User uploaded files

Stored in DATA_DIR /media.

You should back up all user uploaded files (e.g. Visual context for strings).

Celery tasks

The Celery task queue might contain some info, but is usually not needed for a backup. At most you will lose updates not yet been processed to translation memory. It is recommended to perform the fulltext or repository update upon restoration anyhow, so there is no problem in losing these.

See also

Background tasks using Celery

Command-line for manual backup

Using a cron job, you can set up a Bash command to be executed on a daily basis, for example:

$ XZ_OPT="-9" tar -Jcf ~/backup/weblate-backup-$(date -u +%Y-%m-%d_%H%M%S).xz backups vcs ssh home media fonts secret

The string between the quotes after XZ_OPT allows you to choose your xz options, for instance the amount of memory used for compression; see https://linux.die.net/man/1/xz

You can adjust the list of folders and files to your needs. To avoid saving the translation memory (in backups folder), you can use:

$ XZ_OPT="-9" tar -Jcf ~/backup/weblate-backup-$(date -u +%Y-%m-%d_%H%M%S).xz backups/database.sql backups/settings.py vcs ssh home media fonts secret

Restoring manual backup

Restore all data you have backed up.
Update all repositories using updategit.
```
weblate updategit --all
```

Moving a Weblate installation

Relocate your installation to a different system by following the backing up and restoration instructions above.

Authentication

User registration

The default setup for Weblate is to use python-social-auth, a form on the website to handle registration of new users. After confirming their e-mail a new user can contribute or authenticate by using one of the third party services.

You can also turn off registration of new users using REGISTRATION_OPEN.

The authentication attempts are subject to Rate limiting.

Authentication backends

The built-in solution of Django is used for authentication, including various social options to do so. Using it means you can import the user database of other Django-based projects (see Migrating from Pootle).

Django can additionally be set up to authenticate against other means too.

See also

Authentication settings describes how to configure authentication in the official Docker image.

Password authentication

The default settings.py comes with a reasonable set of AUTH_PASSWORD_VALIDATORS:

Passwords can’t be too similar to your other personal info.
Passwords must contain at least 10 characters.
Passwords can’t be a commonly used password.
Passwords can’t be entirely numeric.
Passwords can’t consist of a single character or only whitespace.
Passwords can’t match a password you have used in the past.

You can customize this setting to match your password policy.

Additionally you can also install django-zxcvbn-password which gives quite realistic estimates of password difficulty and allows rejecting passwords below a certain threshold.

SAML authentication

New in version 4.1.1.

Please follow the Python Social Auth instructions for configuration. Notable differences:

Weblate supports single IDP which has to be called weblate in SOCIAL_AUTH_SAML_ENABLED_IDPS.
The SAML XML metadata URL is /accounts/metadata/saml/.
Following settings are automatically filled in: SOCIAL_AUTH_SAML_SP_ENTITY_ID, SOCIAL_AUTH_SAML_TECHNICAL_CONTACT, SOCIAL_AUTH_SAML_SUPPORT_CONTACT

Example configuration:

# Authentication configuration
AUTHENTICATION_BACKENDS = (
    "social_core.backends.email.EmailAuth",
    "social_core.backends.saml.SAMLAuth",
    "weblate.accounts.auth.WeblateUserBackend",
)

# Social auth backends setup
SOCIAL_AUTH_SAML_SP_ENTITY_ID = f"https://{SITE_DOMAIN}/accounts/metadata/saml/"
SOCIAL_AUTH_SAML_SP_PUBLIC_CERT = "-----BEGIN CERTIFICATE-----"
SOCIAL_AUTH_SAML_SP_PRIVATE_KEY = "-----BEGIN PRIVATE KEY-----"
SOCIAL_AUTH_SAML_ENABLED_IDPS = {
    "weblate": {
        "entity_id": "https://idp.testshib.org/idp/shibboleth",
        "url": "https://idp.testshib.org/idp/profile/SAML2/Redirect/SSO",
        "x509cert": "MIIEDjCCAvagAwIBAgIBADA ... 8Bbnl+ev0peYzxFyF5sQA==",
        "attr_name": "full_name",
        "attr_username": "username",
        "attr_email": "email",
    }
}
SOCIAL_AUTH_SAML_ORG_INFO = {
    "en-US": {
        "name": "example",
        "displayname": "Example Inc.",
        "url": "http://example.com"
    }
}
SOCIAL_AUTH_SAML_TECHNICAL_CONTACT = {
    "givenName": "Tech Gal",
    "emailAddress": "technical@example.com"
}
SOCIAL_AUTH_SAML_SUPPORT_CONTACT = {
    "givenName": "Support Guy",
    "emailAddress": "support@example.com"
}

The default configuration extracts user details from following attributes, configure your IDP to provide them:

Attribute	SAML URI reference
Full name	`urn:oid:2.5.4.3`
First name	`urn:oid:2.5.4.42`
Last name	`urn:oid:2.5.4.4`
E-mail	`urn:oid:0.9.2342.19200300.100.1.3`
Username	`urn:oid:0.9.2342.19200300.100.1.1`

Hint

The example above and the Docker image define an IDP labelled weblate. You might need to configure this string as Relay in your IDP.

Configuring SAML in Docker, SAML

LDAP authentication

LDAP authentication can be best achieved using the django-auth-ldap package. You can install it via usual means:

# Using PyPI
pip install django-auth-ldap>=1.3.0

# Using apt-get
apt-get install python-django-auth-ldap

Hint

This package is included in the Docker container, see Installing using Docker.

Note

There are some incompatibilities in the Python LDAP 3.1.0 module, which might prevent you from using that version. If you get error AttributeError: ‘module’ object has no attribute ‘_trace_level’, downgrading python-ldap to 3.0.0 might help.

Once you have the package installed, you can hook it into the Django authentication:

# Add LDAP backed, keep Django one if you want to be able to sign in
# even without LDAP for admin account
AUTHENTICATION_BACKENDS = (
    "django_auth_ldap.backend.LDAPBackend",
    "weblate.accounts.auth.WeblateUserBackend",
)

# LDAP server address
AUTH_LDAP_SERVER_URI = "ldaps://ldap.example.net"

# DN to use for authentication
AUTH_LDAP_USER_DN_TEMPLATE = "cn=%(user)s,o=Example"
# Depending on your LDAP server, you might use a different DN
# like:
# AUTH_LDAP_USER_DN_TEMPLATE = 'ou=users,dc=example,dc=com'

# List of attributes to import from LDAP upon sign in
# Weblate stores full name of the user in the full_name attribute
AUTH_LDAP_USER_ATTR_MAP = {
    "full_name": "name",
    # Use the following if your LDAP server does not have full name
    # Weblate will merge them later
    # 'first_name': 'givenName',
    # 'last_name': 'sn',
    # Email is required for Weblate (used in VCS commits)
    "email": "mail",
}

# Hide the registration form
REGISTRATION_OPEN = False

Note

You should remove 'social_core.backends.email.EmailAuth' from the AUTHENTICATION_BACKENDS setting, otherwise users will be able to set their password in Weblate, and authenticate using that. Keeping 'weblate.accounts.auth.WeblateUserBackend' is still needed in order to make permissions and facilitate anonymous users. It will also allow you to sign in using a local admin account, if you have created it (e.g. by using createadmin).

Using bind password

If you can not use direct bind for authentication, you will need to use search, and provide a user to bind for the search. For example:

import ldap
from django_auth_ldap.config import LDAPSearch

AUTH_LDAP_BIND_DN = ""
AUTH_LDAP_BIND_PASSWORD = ""
AUTH_LDAP_USER_SEARCH = LDAPSearch(
    "ou=users,dc=example,dc=com", ldap.SCOPE_SUBTREE, "(uid=%(user)s)"
)

Active Directory integration

import ldap
from django_auth_ldap.config import LDAPSearch, NestedActiveDirectoryGroupType

AUTH_LDAP_BIND_DN = "CN=ldap,CN=Users,DC=example,DC=com"
AUTH_LDAP_BIND_PASSWORD = "password"

# User and group search objects and types
AUTH_LDAP_USER_SEARCH = LDAPSearch(
    "CN=Users,DC=example,DC=com", ldap.SCOPE_SUBTREE, "(sAMAccountName=%(user)s)"
)

# Make selected group a superuser in Weblate
AUTH_LDAP_USER_FLAGS_BY_GROUP = {
    # is_superuser means user has all permissions
    "is_superuser": "CN=weblate_AdminUsers,OU=Groups,DC=example,DC=com",
}

# Map groups from AD to Weblate
AUTH_LDAP_GROUP_SEARCH = LDAPSearch(
    "OU=Groups,DC=example,DC=com", ldap.SCOPE_SUBTREE, "(objectClass=group)"
)
AUTH_LDAP_GROUP_TYPE = NestedActiveDirectoryGroupType()
AUTH_LDAP_FIND_GROUP_PERMS = True

# Optionally enable group mirroring from LDAP to Weblate
# AUTH_LDAP_MIRROR_GROUPS = True

CAS authentication

CAS authentication can be achieved using a package such as django-cas-ng.

Step one is disclosing the e-mail field of the user via CAS. This has to be configured on the CAS server itself, and requires you run at least CAS v2 since CAS v1 doesn’t support attributes at all.

Step two is updating Weblate to use your CAS server and attributes.

To install django-cas-ng:

pip install django-cas-ng

Once you have the package installed you can hook it up to the Django authentication system by modifying the settings.py file:

# Add CAS backed, keep the Django one if you want to be able to sign in
# even without LDAP for the admin account
AUTHENTICATION_BACKENDS = (
    "django_cas_ng.backends.CASBackend",
    "weblate.accounts.auth.WeblateUserBackend",
)

# CAS server address
CAS_SERVER_URL = "https://cas.example.net/cas/"

# Add django_cas_ng somewhere in the list of INSTALLED_APPS
INSTALLED_APPS = (..., "django_cas_ng")

Finally, a signal can be used to map the e-mail field to the user object. For this to work you have to import the signal from the django-cas-ng package and connect your code with this signal. Doing this in settings file can cause problems, therefore it’s suggested to put it:

In your app config’s django.apps.AppConfig.ready() method
In the project’s urls.py file (when no models exist)

from django_cas_ng.signals import cas_user_authenticated
from django.dispatch import receiver


@receiver(cas_user_authenticated)
def update_user_email_address(sender, user=None, attributes=None, **kwargs):
    # If your CAS server does not always include the email attribute
    # you can wrap the next two lines of code in a try/catch block.
    user.email = attributes["email"]
    user.save()

See also

Django CAS NG

Configuring third party Django authentication

Generally any Django authentication plugin should work with Weblate. Just follow the instructions for the plugin, just remember to keep the Weblate user backend installed.

See also

LDAP authentication, CAS authentication

Typically the installation will consist of adding an authentication backend to AUTHENTICATION_BACKENDS and installing an authentication app (if there is any) into INSTALLED_APPS:

AUTHENTICATION_BACKENDS = (
    # Add authentication backend here
    "weblate.accounts.auth.WeblateUserBackend",
)

INSTALLED_APPS += (
    # Install authentication app here
)

Access control

Weblate comes with a fine-grained privilege system to assign user permissions for the whole instance, or in a limited scope.

Changed in version 3.0: Before Weblate 3.0, the privilege system was based on Django privilege system only, but is specifically built for Weblate now. If using anything older, please consult the documentation for the specific version you are using.

Simple access control

If you are not administrating the whole Weblate installation and just have access to manage certain projects (like on Hosted Weblate), your access control management options are limited to following settings. If you don’t need any complex setup, those are sufficient for you.

Project access control

Note

This feature is unavailable for projects running the Libre plan on Hosted Weblate.

You can limit user’s access to individual projects by selecting a different Access control setting. Available options are:

Public: Publicly visible, translatable for all logged-in users.
Protected: Publicly visible, but translatable only for selected users.
Private: Visible and translatable only for selected users.
Custom: User management features will be disabled; by default all users are forbidden to performed any actions on the project. You will have to set up all the permissions using Custom access control.

Access control can be changed in the Access tab of the configuration (Manage ↓ Settings) of each respective project.

The default value can be changed by DEFAULT_ACCESS_CONTROL.

Note

Even for Private projects, some info about your project will be exposed: statistics and language summary for the whole instance will include counts for all projects despite the access control setting. Your project name and other information can’t be revealed through this.

Note

The actual set of permissions available for users by default in Public, Protected, and Private projects can be redefined by Weblate instance administrator using custom settings.

Warning

By turning on Custom access control, Weblate will remove all special groups it has created for a selected project. If you are doing this without admin permission for the whole Weblate instance, you will instantly lose your access to manage the project.

See also

Access control

Managing per-project access control

Users with the Manage project access privilege (see List of privileges) can manage users in projects with non-Custom access control. They can assign users to one of the following groups.

For Public, Protected and Private projects:

Administration: Includes all permissions available for the project.
Review (only if review workflow is turned on): Can approve translations during review.

For Protected and Private projects only:

Translate: Can translate the project and upload translations made offline.
Sources: Can edit source strings (if allowed in the project settings) and source string info.
Languages: Can manage translated languages (add or remove translations).
Glossary: Can manage glossary (add or remove entries, also upload).
Memory: Can manage translation memory.
Screenshots: Can manage screenshots (add or remove them, and associate them to source strings).
VCS: Can manage VCS and access the exported repository.
Billing: Can access billing info and settings (see Billing).

Unfortunately, it’s not possible to change this predefined set of groups for now. Also this way it’s not possible to give just some additional permissions to all users.

Note

For non-Custom access control an instance of each group described above is actually defined for each project. The actual name of those groups will be Project@Group, also displayed in the Django admin interface this way. Although they can’t be edited from Weblate user-interface.

These features are available on the Access control page, which can be accessed from the project’s menu Manage ↓ Users.

New user invitation

Also, besides adding an existing user to the project, it is possible to invite new ones. Any new user will be created immediately, but the account will remain inactive until signing in with a link in the invitation sent via an e-mail. It is not required to have any site-wide privileges in order to do so, access management permission on the project’s scope (e.g. a membership in the Administration group) would be sufficient.

Hint

If the invited user missed the validity of the invitation, they can set their password using invited e-mail address in the password reset form as the account is created already.

New in version 3.11: It is possible to resend the e-mail for user invitations (invalidating any previously sent invitation).

The same kind of invitations are available site-wide from the management interface on the Users tab.

Blocking users

New in version 4.7.

In case some users behave badly in your project, you have an option to block them from contributing. The blocked user still will be able to see the project if he has permissions for that, but he won’t be able to contribute.

Per-project permission management

You can set your projects to Protected or Private, and manage users per-project in the Weblate user interface.

By default this prevents Weblate from granting access provided by Users and Viewers default groups due to these groups’ own configuration. This doesn’t prevent you from granting permissions to those projects site-wide by altering default groups, creating a new one, or creating additional custom settings for individual component as described in Custom access control below.

One of the main benefits of managing permissions through the Weblate user interface is that you can delegate it to other users without giving them the superuser privilege. In order to do so, add them to the Administration group of the project.

Custom access control

Note

This feature is unavailable for projects running the Libre plan on Hosted Weblate.

The permission system is based on groups and roles, where roles define a set of permissions, and groups link them to users and translations, see Users, roles, groups, and permissions for more details.

The most powerful features of the Weblate’s access control system for now are available only through the Django admin interface. You can use it to manage permissions of any project. You don’t necessarily have to switch it to Custom access control to utilize it. However you must have superuser privileges in order to use it.

If you are not interested in details of implementation, and just want to create a simple-enough configuration based on the defaults, or don’t have a site-wide access to the whole Weblate installation (like on Hosted Weblate), please refer to the Simple access control section.

Common setups

This section contains an overview of some common configurations you may be interested in.

Site-wide permission management

To manage permissions for a whole instance at once, add users to appropriate default groups:

Users (this is done by default by the automatic group assignment).
Reviewers (if you are using review workflow with dedicated reviewers).
Managers (if you want to delegate most of the management operations to somebody else).

You should keep all projects configured as Public (see Project access control), otherwise the site-wide permissions provided by membership in the Users and Reviewers groups won’t have any effect.

You may also grant some additional permissions of your choice to the default groups. For example, you may want to give a permission to manage screenshots to all the Users.

You can define some new custom groups as well. If you want to keep managing your permissions site-wide for these groups, choose an appropriate value for the Project selection (e.g. All projects or All public projects).

Custom permissions for languages, components or projects

You can create your own dedicated groups to manage permissions for distinct objects such as languages, components, and projects. Although these groups can only grant additional privileges, you can’t revoke any permission granted by site-wide or per-project groups by adding another custom group.

Example:

If you want (for whatever reason) to allow translation to a specific language (lets say Czech) only to a closed set of reliable translators while keeping translations to other languages public, you will have to:

Remove the permission to translate Czech from all the users. In the default configuration this can be done by altering the Users default group.

Add users you wish to give the permissions to into this group.

As you can see, permissions management this way is powerful, but can be quite a tedious job. You can’t delegate it to another user, unless granting superuser permissions.

Users, roles, groups, and permissions

The authentication models consist of several objects:

Permission: Individual permission defined by Weblate. Permissions cannot be assigned to users. This can only be done through assignment of roles.
Role: A role defines a set of permissions. This allows reuse of these sets in several places, making the administration easier.
User: User can belong to several groups.
Group: Group connect roles, users, and authentication objects (projects, languages, and component lists).

Note

A group can have no roles assigned to it, in that case access to browse the project by anyone is assumed (see below).

Access for browse to a project

A user has to be a member of a group linked to the project, or any component inside that project. Having membership is enough, no specific permissions are needed to browse the project (this is used in the default Viewers group, see List of groups).

Access for browse to a component

A user can access unrestricted components once able to access the components’ project (and will have all the permissions the user was granted for the project). With Restricted access turned on, access to the component requires explicit permissions for the component (or a component list the component is in).

Scope of groups

The scope of the permission assigned by the roles in the groups are applied by the following rules:

If the group specifies any Component list, all the permissions given to members of that group are granted for all the components in the component lists attached to the group, and an access with no additional permissions is granted for all the projects these components are in. Components and Projects are ignored.
If the group specifies any Components, all the permissions given to the members of that group are granted for all the components attached to the group, and an access with no additional permissions is granted for all the projects these components are in. Projects are ignored.
Otherwise, if the group specifies any Projects, either by directly listing them or by having Projects selection set to a value like All public projects, all those permissions are applied to all the projects, which effectively grants the same permissions to access all projects unrestricted components.
The restrictions imposed by a group’s Languages are applied separately, when it’s verified if a user has an access to perform certain actions. Namely, it’s applied only to actions directly related to the translation process itself like reviewing, saving translations, adding suggestions, etc.

Hint

Use Language selection or Project selection to automate inclusion of all languages or projects.

Example:

Let’s say there is a project foo with the components: foo/bar and foo/baz and the following group:

Group Spanish Admin-Reviewers

Roles

Review Strings, Manage repository

Components

foo/bar

Languages

Spanish

Group Spanish Admin-Reviewers
Roles	Review Strings, Manage repository
Components	foo/bar
Languages	Spanish

Members of that group will have following permissions (assuming the default role settings):

General (browsing) access to the whole project foo including both components in it: foo/bar and foo/baz.

Review strings in foo/bar Spanish translation (not elsewhere).

Manage VCS for the whole foo/bar repository e.g. commit pending changes made by translators for all languages.

Automatic group assignments

On the bottom of the Group editing page in the Django admin interface, you can specify Automatic group assignments, which is a list of regular expressions used to automatically assign newly created users to a group based on their e-mail addresses. This assignment only happens upon account creation.

The most common use-case for the feature is to assign all new users to some default group. In order to do so, you will probably want to keep the default value (^.*$) in the regular expression field. Another use-case for this option might be to give some additional privileges to employees of your company by default. Assuming all of them use corporate e-mail addresses on your domain, this can be accomplished with an expression like ^.*@mycompany.com.

Note

Automatic group assignment to Users and Viewers is always recreated when upgrading from one Weblate version to another. If you want to turn it off, set the regular expression to ^$ (which won’t match anything).

Note

As for now, there is no way to bulk-add already existing users to some group via the user interface. For that, you may resort to using the REST API.

Default groups and roles

After installation, a default set of groups is created (see List of groups).

These roles and groups are created upon installation. The built-in roles are always kept up to date by the database migration when upgrading. You can’t actually change them, please define a new role if you want to define your own set of permissions.

Note

Site-wide privileges are not granted to any default role. These are powerful and quite close to superuser status. Most of them affect all projects in your Weblate installation.

List of groups

The following groups are created upon installation (or after executing setupgroups) and you are free to modify them. The migration will, however, re-create them if you delete or rename them.

Guests

Defines permissions for non-authenticated users.

This group only contains anonymous users (see ANONYMOUS_USER_NAME).

You can remove roles from this group to limit permissions for non-authenticated users.

Default roles: Add suggestion, Access repository

Viewers

This role ensures visibility of public projects for all users. By default, all users are members of this group.

By default, automatic group assignment makes all new accounts members of this group when they join.

Default roles: none

Users

Default group for all users.

By default, automatic group assignment makes all new accounts members of this group when they join.

Default roles: Power user

Reviewers

Default roles: Review strings

Managers

Group for administrators.

Default roles: Administration

Warning

Never remove the predefined Weblate groups and users as this can lead to unexpected problems! If you have no use for them, you can removing all their privileges instead.

Additional access restrictions

If you want to use your Weblate installation in a less public manner, i.e. allow new users on an invitational basis only, it can be done by configuring Weblate in such a way that only known users have an access to it. In order to do so, you can set REGISTRATION_OPEN to False to prevent registrations of any new users, and set REQUIRE_LOGIN to /.* to require logging-in to access all the site pages. This is basically the way to lock your Weblate installation.

Hint

You can use built-in invitations to add new users.

Translation projects

Translation organization

Weblate organizes translatable VCS content of project/components into a tree-like structure.

The bottom level object is Project configuration, which should hold all translations belonging together (for example translation of an application in several versions and/or accompanying documentation).
On the level above, Component configuration, which is actually the component to translate, you define the VCS repository to use, and the mask of files to translate.
Above Component configuration there are individual translations, handled automatically by Weblate as translation files (which match File mask defined in Component configuration) appear in the VCS repository.

Weblate supports a wide range of translation formats (both bilingual and monolingual ones) supported by Translate Toolkit, see Supported file formats.

Note

You can share cloned VCS repositories using Weblate internal URLs. Using this feature is highly recommended when you have many components sharing the same VCS. It improves performance and decreases required disk space.

Adding translation projects and components

Changed in version 3.2: An interface for adding projects and components is included, and you no longer have to use The Django admin interface.

Changed in version 3.4: The process of adding components is now multi staged, with automated discovery of most parameters.

Based on your permissions, new translation projects and components can be created. It is always permitted for users with the Add new projects permission, and if your instance uses billing (e.g. like https://hosted.weblate.org/ see Billing), you can also create those based on your plans allowance from the user account that manages billing.

You can view your current billing plan on a separate page:

The project creation can be initiated from there, or using the menu in the navigation bar, filling in basic info about the translation project to complete addition of it:

After creating the project, you are taken directly to the project page:

Creating a new translation component can be initiated via a single click there. The process of creating a component is multi-staged and automatically detects most translation parameters. There are several approaches to creating component:

From version control: Creates component from remote version control repository.
From existing component: Creates additional component to existing one by choosing different files.
Additional branch: Creates additional component to existing one, just for different branch.
Upload translations files: Upload translation files to Weblate in case you do not have version control or do not want to integrate it with Weblate. You can later update the content using the web interface or Weblate’s REST API.
Translate document: Upload single document or translation file and translate that.
Start from scratch: Create blank translation project and add strings manually.

Once you have existing translation components, you can also easily add new ones for additional files or branches using same repository.

First you need to fill in name and repository location:

On the next page, you are presented with a list of discovered translatable resources:

_images/user-add-component-discovery.png

As a last step, you review the translation component info and fill in optional details:

Project configuration

Create a translation project and then add a new component for translation in it. The project is like a shelf, in which real translations are stacked. All components in the same project share suggestions and their dictionary; the translations are also automatically propagated through all components in a single project (unless turned off in the component configuration), see Translation Memory.

See also

Integrating with Weblate

These basic attributes set up and inform translators of a project:

Project name

Verbose project name, used to display the project name.

URL slug

Project name suitable for URLs.

Project website

URL where translators can find more info about the project.

This is a required parameter unless turned off by WEBSITE_REQUIRED.

Translation instructions

Text describing localization process in the project, and any other information useful for translators. Markdown can be used for text formatting or inserting links.

Set “Language-Team” header

Whether Weblate should manage the Language-Team header (this is a GNU gettext only feature right now).

Use shared translation memory

Whether to use shared translation memory, see Shared translation memory for more details.

Default value is determined by DEFAULT_SHARED_TM.

Contribute to shared translation memory

Whether to contribute to shared translation memory, see Shared translation memory for more details.

Default value is determined by DEFAULT_SHARED_TM.

Access control

Configure per project access control, see Project access control for more details.

Default value can be changed by DEFAULT_ACCESS_CONTROL.

Enable reviews

Enable review workflow for translations, see Dedicated reviewers.

Enable source reviews

Enable review workflow for source strings, see Source strings reviews.

Enable hooks

Whether unauthenticated Notification hooks are to be used for this repository.

Language aliases

Define language codes mapping when importing translations into Weblate. Use this when language codes are inconsistent in your repositories and you want to get a consistent view in Weblate or in case you want to use non-standard naming of your translation files.

The typical use case might be mapping American English to English: en_US:en

Multiple mappings to be separated by comma: en_GB:en,en_US:en

Using non standard code: ia_FOO:ia

Hint

The language codes are mapped when matching the translation files and the matches are case sensitive, so make sure you use the source language codes in same form as used in the filenames.

See also

Parsing language codes

Component configuration

A component is a grouping of something for translation. You enter a VCS repository location and file mask for which files you want translated, and Weblate automatically fetches from this VCS, and finds all matching translatable files.

See also

Integrating with Weblate

You can find some examples of typical configurations in the Supported file formats.

Note

It is recommended to keep translation components to a reasonable size - split the translation by anything that makes sense in your case (individual apps or addons, book chapters or websites).

Weblate easily handles translations with 10000s of strings, but it is harder to split work and coordinate among translators with such large translation components.

Should the language definition for a translation be missing, an empty definition is created and named as “cs_CZ (generated)”. You should adjust the definition and report this back to the Weblate authors, so that the missing languages can be included in next release.

The component contains all important parameters for working with the VCS, and for getting translations out of it:

Component name

Verbose component name, used to display the component name.

Component slug

Component name suitable for URLs.

Component project

Project configuration where the component belongs.

Version control system

VCS to use, see Version control integration for details.

See also

Pushing changes from Weblate

Source code repository

VCS repository used to pull changes.

See also

See Accessing repositories for more details on specifying URLs.

Hint

This can either be a real VCS URL or weblate://project/component indicating that the repository should be shared with another component. See Weblate internal URLs for more details.

Repository push URL

Repository URL used for pushing. This setting is used only for Git and Mercurial and push support is turned off for these when this is empty.

For linked repositories, this is not used and setting from linked component applies.

See also

See Accessing repositories for more details on how to specify a repository URL and Pushing changes from Weblate for more details on pushing changes from Weblate.

Repository browser

URL of repository browser used to display source files (location of used messages). When empty, no such links will be generated. You can use Template markup.

For example on GitHub, use something like: https://github.com/WeblateOrg/hello/blob/{{branch}}/{{filename}}#L{{line}}

In case your paths are relative to different folder (path contains ..), you might want to strip leading directory by parentdir filter (see Template markup): https://github.com/WeblateOrg/hello/blob/{{branch}}/{{filename|parentdir}}#L{{line}}

Exported repository URL

URL where changes made by Weblate are exported. This is important when Continuous localization is not used, or when there is a need to manually merge changes. You can use Git exporter to automate this for Git repositories.

Repository branch

Which branch to checkout from the VCS, and where to look for translations.

For linked repositories, this is not used and setting from linked component applies.

Push branch

Branch for pushing changes, leave empty to use Repository branch.

For linked repositories, this is not used and setting from linked component applies.

Note

This is currently only supported for Git, GitLab and GitHub, it is ignored for other VCS integrations.

See also

Pushing changes from Weblate

File mask

Mask of files to translate, including path. It should include one “*” replacing language code (see Language definitions for info on how this is processed). In case your repository contains more than one translation file (e.g. more gettext domains), you need to create a component for each of them.

For example po/*.po or locale/*/LC_MESSAGES/django.po.

In case your filename contains special characters such as [, ], these need to be escaped as [[] or []].

Monolingual base language file

Base file containing string definitions for Monolingual components.

Edit base file

Whether to allow editing the base file for Monolingual components.

Intermediate language file

Intermediate language file for Monolingual components. In most cases this is a translation file provided by developers and is used when creating actual source strings.

When set, the source strings are based on this file, but all other languages are based on Monolingual base language file. In case the string is not translated into the source language, translating to other languages is prohibited. This provides Quality gateway for the source strings.

Template for new translations

Base file used to generate new translations, e.g. .pot file with gettext.

Hint

In many monolingual formats Weblate starts with blank file by default. Use this in case you want to have all strings present with empty value when creating new translation.

File format

Translation file format, see also Supported file formats.

Source string bug reporting address

Email address used for reporting upstream bugs. This address will also receive notification about any source string comments made in Weblate.

Allow translation propagation

You can turn off propagation of translations to this component from other components within same project. This really depends on what you are translating, sometimes it’s desirable to have make use of a translation more than once.

It’s usually a good idea to turn this off for monolingual translations, unless you are using the same IDs across the whole project.

Default value can be changed by DEFAULT_TRANSLATION_PROPAGATION.

Enable suggestions

Whether translation suggestions are accepted for this component.

Suggestion voting

Turns on vote casting for suggestions, see Suggestion voting.

Autoaccept suggestions

Automatically accept voted suggestions, see Suggestion voting.

Translation flags

Customization of quality checks and other Weblate behavior, see Customizing behavior using flags.

Enforced checks

List of checks which can not be ignored, see Enforcing checks.

Note

Enforcing the check does not automatically enable it, you still should enabled it using Customizing behavior using flags in Translation flags or Additional info on source strings.

Translation license

License of the translation (does not need to be the same as the source code license).

Contributor agreement

User agreement which needs to be approved before a user can translate this component.

Adding new translation

How to handle requests for creation of new languages. Available options:

Contact maintainers: User can select desired language and the project maintainers will receive a notification about this. It is up to them to add (or not) the language to the repository.
Point to translation instructions URL: User is presented a link to page which describes process of starting new translations. Use this in case more formal process is desired (for example forming a team of people before starting actual translation).
Create new language file: User can select language and Weblate automatically creates the file for it and translation can begin.
Disable adding new translations: There will be no option for user to start new translation.

Hint

The project admins can add new translations even if it is disabled here when it is possible (either Template for new translations or the file format supports starting from an empty file).

Manage strings

New in version 4.5.

Configures whether users in Weblate will be allowed to add new strings and remove existing ones. Adjust this to match your localization workflow - how the new strings are supposed to be introduced.

For bilingual formats, the strings are typically extracted from the source code (for example by using xgettext) and adding new strings in Weblate should be disabled (they would be discarded next time you update the translation files). In Weblate you can manage strings for every translation and it does not enforce the strings in all translations to be consistent.

For monolingual formats, the strings are managed only on source language and are automatically added or removed in the translations. The strings appear in the translation files once they are translated.

Language code style

Customize language code used to generate the filename for translations created by Weblate.

Merge style

You can configure how updates from the upstream repository are handled. The actual implementation depends on VCS, see Version control integration.

Rebase

Rebases Weblate commits on top of upstream repository on update. This provides clean history without extra merge commits.

Rebasing can cause you trouble in case of complicated merges, so carefully consider whether or not you want to enable them.

You might need to enable force pushing by choosing Git with force push as Version control system, especially when pushing to a different branch.

Merge

Upstream repository changed are merged into Weblate one. This is the safest way, but might produce a lot of merge commits.

Default value can be changed by DEFAULT_MERGE_STYLE.

Commit, add, delete, merge and addon messages

Message used when committing a translation, see Template markup.

Default value can be changed by DEFAULT_ADD_MESSAGE, DEFAULT_ADDON_MESSAGE, DEFAULT_COMMIT_MESSAGE, DEFAULT_DELETE_MESSAGE, DEFAULT_MERGE_MESSAGE.

Push on commit

Whether committed changes should be automatically pushed to the upstream repository. When enabled, the push is initiated once Weblate commits changes to its underlying repository (see Lazy commits). To actually enable pushing Repository push URL has to be configured as well.

Age of changes to commit

Sets how old (in hours) changes have to be before they are committed by background task or the commit_pending management command. All changes in a component are committed once there is at least one change older than this period.

Default value can be changed by COMMIT_PENDING_HOURS.

Hint

There are other situations where pending changes might be committed, see Lazy commits.

Lock on error

Locks the component (and linked components, see Weblate internal URLs) upon the first failed push or merge into its upstream repository, or pull from it. This avoids adding another conflicts, which would have to be resolved manually.

The component will be automatically unlocked once there are no repository errors left.

Source language

Language used for source strings. Change this if you are translating from something else than English.

Hint

In case you are translating bilingual files from English, but want to be able to do fixes in the English translation as well, choose English (Developer) as a source language to avoid conflict between the name of the source language and the existing translation.

For monolingual translations, you can use intermediate translation in this case, see Intermediate language file.

Language filter

Regular expression used to filter the translation when scanning for filemask. It can be used to limit the list of languages managed by Weblate.

Note

You need to list language codes as they appear in the filename.

Some examples of filtering:

Filter description	Regular expression
Selected languages only	`^(cs\|de\|es)$`
Exclude languages	`^(?!(it\|fr)$).+$`
Filter two letter codes only	`^..$`
Exclude non language files	`^(?!(blank)$).+$`
Include all files (default)	`^[^.]+$`

Variants regular expression

Regular expression used to determine the variants of a string, see String variants.

Note

Most of the fields can be edited by project owners or managers, in the Weblate interface.

Priority

Components with higher priority are offered first to translators.

Restricted access

By default the component is visible to anybody who has access to the project, even if the person can not perform any changes in the component. This makes it easier to keep translation consistency within the project.

Restricting access at a component, or component-list level takes over access permission to a component, regardless of project-level permissions. You will have to grant access to it explicitly. This can be done through granting access to a new user group and putting users in it, or using the default custom or private access control groups.

The default value can be changed in DEFAULT_RESTRICTED_COMPONENT.

Hint

This applies to project admins as well — please make sure you will not loose access to the component after toggling the status.

Use as a glossary

New in version 4.5.

Allows using this component as a glossary. You can configure how it will be listed using Glossary color.

The glossary will be accessible in all projects defined by Share in projects.

It is recommended to enable Manage strings on glossaries in order to allow adding new words to them.

See also

Glossary

Glossary color

Display color for a glossary used when showing word matches.

Template markup

Weblate uses simple markup language in several places where text rendering is needed. It is based on The Django template language, so it can be quite powerful.

Currently it is used in:

Commit message formatting, see Component configuration
Several addons

There following variables are available in the component templates:

{{ language_code }}: Language code
{{ language_name }}: Language name
{{ component_name }}: Component name
{{ component_slug }}: Component slug
{{ project_name }}: Project name
{{ project_slug }}: Project slug
{{ url }}: Translation URL
{{ filename }}: Translation filename
{{ stats }}: Translation stats, this has further attributes, examples below.
{{ stats.all }}: Total strings count
{{ stats.fuzzy }}: Count of strings needing review
{{ stats.fuzzy_percent }}: Percent of strings needing review
{{ stats.translated }}: Translated strings count
{{ stats.translated_percent }}: Translated strings percent
{{ stats.allchecks }}: Number of strings with failing checks
{{ stats.allchecks_percent }}: Percent of strings with failing checks
{{ author }}: Author of current commit, available only in the commit scope.
{{ addon_name }}: Name of currently executed addon, available only in the addon commit message.

The following variables are available in the repository browser or editor templates:

{{branch}}: current branch
{{line}}: line in file
{{filename}}: filename, you can also strip leading parts using the parentdir filter, for example {{filename|parentdir}}

You can combine them with filters:

{{ component|title }}

You can use conditions:

{% if stats.translated_percent > 80 %}Well translated!{% endif %}

There is additional tag available for replacing characters:

{% replace component "-" " " %}

You can combine it with filters:

{% replace component|capfirst "-" " " %}

There are also additional filter to manipulate with filenames:

Directory of a file: {{ filename|dirname }}
File without extension: {{ filename|stripext }}
File in parent dir: {{ filename|parentdir }}
It can be used multiple times:  {{ filename|parentdir|parentdir }}

…and other Django template features.

Importing speed

Fetching VCS repository and importing translations to Weblate can be a lengthy process, depending on size of your translations. Here are some tips:

Optimize configuration

The default configuration is useful for testing and debugging Weblate, while for a production setup, you should do some adjustments. Many of them have quite a big impact on performance. Please check Production setup for more details, especially:

Configure Celery for executing background tasks (see Background tasks using Celery)
Enable caching
Use a powerful database engine
Disable debug mode

Check resource limits

If you are importing huge translations or repositories, you might be hit by resource limitations of your server.

Check the amount of free memory, having translation files cached by the operating system will greatly improve performance.
Disk operations might be bottleneck if there is a lot of strings to process—the disk is pushed by both Weblate and the database.
Additional CPU cores might help improve performance of background tasks (see Background tasks using Celery).

Disable unneeded checks

Some quality checks can be quite expensive, and if not needed, can save you some time during import if omitted. See CHECK_LIST for info on configuration.

Automatic creation of components

In case your project has dozen of translation files (e.g. for different gettext domains, or parts of Android apps), you might want to import them automatically. This can either be achieved from the command-line by using import_project or import_json, or by installing the Component discovery addon.

To use the addon, you first need to create a component for one translation file (choose the one that is the least likely to be renamed or removed in future), and install the addon on this component.

For the management commands, you need to create a project which will contain all components and then run import_project or import_json.

Language definitions

To present different translations properly, info about language name, text direction, plural definitions and language code is needed.

Parsing language codes

While parsing translations, Weblate attempts to map language code (usually the ISO 639-1 one) to any existing language object.

You can further adjust this mapping at project level by Language aliases.

If no exact match can be found, an attempt will be made to best fit it into an existing language. Following steps are tried:

Case insensitive lookups.
Normalizing underscores and dashes.
Looking up built-in language aliases.
Looking up by language name.
Ignoring the default country code for a given language—choosing cs instead of cs_CZ.

Should that also fail, a new language definition will be created using the defaults (left to right text direction, one plural). The automatically created language with code xx_XX will be named as xx_XX (generated). You might want to change this in the admin interface later, (see Changing language definitions) and report it to the issue tracker (see Contributing to Weblate), so that the proper definition can be added to the upcoming Weblate release.

Hint

In case you see something unwanted as a language, you might want to adjust Language filter to ignore such file when parsing translations.

See also

Language code, Adding new translations

Changing language definitions

You can change language definitions in the languages interface (/languages/ URL).

While editing, make sure all fields are correct (especially plurals and text direction), otherwise translators will be unable to properly edit those translations.

Built-in language definitions

Definitions for about 600 languages are included in Weblate and the list is extended in every release. Whenever Weblate is upgraded (more specifically whenever weblate migrate is executed, see Generic upgrade instructions) the database of languages is updated to include all language definitions shipped in Weblate.

This feature can be disable using UPDATE_LANGUAGES. You can also enforce updating the database to match Weblate built-in data using setuplang.

See also

Extending built-in language definitions

Ambiguous language codes and macrolanguages

In many cases it is not a good idea to use macro language code for a translation. The typical problematic case might be Kurdish language, which might be written in Arabic or Latin script, depending on actual variant. To get correct behavior in Weblate, it is recommended to use individual language codes only and avoid macro languages.

Language definitions

Each language consists of following fields:

Language code

Code identifying the language. Weblate prefers two letter codes as defined by ISO 639-1, but uses ISO 639-2 or ISO 639-3 codes for languages that do not have two letter code. It can also support extended codes as defined by BCP 47.

Language name

Visible name of the language. The language names included in Weblate are also being localized depending on user interface language.

Text direction

Determines whether language is written right to left or left to right. This property is autodetected correctly for most of the languages.

Plural number

Number of plurals used in the language.

Plural formula

Gettext compatible plural formula used to determine which plural form is used for given count.

Adding new translations

Changed in version 2.18: In versions prior to 2.18 the behaviour of adding new translations was file format specific.

Weblate can automatically start new translation for all of the file formats.

Some formats expect to start with an empty file and only translated strings to be included (for example Android string resources), while others expect to have all keys present (for example GNU gettext). The document-based formats (for example OpenDocument Format) start with a copy of the source document and all strings marked as needing editing. In some situations this really doesn’t depend on the format, but rather on the framework you use to handle the translation (for example with JSON files).

When you specify Template for new translations in Component configuration, Weblate will use this file to start new translations. Any exiting translations will be removed from the file when doing so.

When Template for new translations is empty and the file format supports it, an empty file is created where new strings will be added once they are translated.

The Language code style allows you to customize language code used in generated filenames:

Default based on the file format: Dependent on file format, for most of them POSIX is used.
POSIX style using underscore as a separator: Typically used by gettext and related tools, produces language codes like pt_BR.
POSIX style using underscore as a separator, including country code: POSIX style language code including the country code even when not necessary (for example cs_CZ).
BCP style using hyphen as a separator: Typically used on web platforms, produces language codes like pt-BR.
BCP style using hyphen as a separator, including country code: BCP style language code including the country code even when not necessary (for example cs-CZ).
Android style: Only used in Android apps, produces language codes like pt-rBR.
Java style: Used by Java—mostly BCP with legacy codes for Chinese.

Additionally, any mappings defined in Language aliases are applied in reverse.

Note

Weblate recognizes any of these when parsing translation files, the above settings only influences how new files are created.

Continuous localization

There is infrastructure in place so that your translation closely follows development. This way translators can work on translations the entire time, instead of working through huge amount of new text just prior to release.

See also

Integrating with Weblate describes basic ways to integrate your development with Weblate.

This is the process:

Developers make changes and push them to the VCS repository.
Optionally the translation files are updated (this depends on the file format, see Why does Weblate still show old translation strings when I’ve updated the template?).
Weblate pulls changes from the VCS repository, see Updating repositories.
Once Weblate detects changes in translations, translators are notified based on their subscription settings.
Translators submit translations using the Weblate web interface, or upload offline changes.
Once the translators are finished, Weblate commits the changes to the local repository (see Lazy commits) and pushes them back if it has permissions to do so (see Pushing changes from Weblate).

Updating repositories

You should set up some way of updating backend repositories from their source.

Use Notification hooks to integrate with most of common code hosting services:
Manually trigger update either in the repository management or using Weblate’s REST API or Weblate Client
Enable AUTO_UPDATE to automatically update all components on your Weblate instance
Execute updategit (with selection of project or --all to update all)

Whenever Weblate updates the repository, the post-update addons will be triggered, see Add-ons.

Avoiding merge conflicts

The merge conflicts from Weblate arise when same file was changed both in Weblate and outside it. There are two approaches to deal with that - avoid edits outside Weblate or integrate Weblate into your updating process, so that it flushes changes prior to updating the files outside Weblate.

The first approach is easy with monolingual files - you can add new strings within Weblate and leave whole editing of the files there. For bilingual files, there is usually some kind of message extraction process to generate translatable files from the source code. In some cases this can be split into two parts - one for the extraction generates template (for example gettext POT is generated using xgettext) and then further process merges it into actual translations (the gettext PO files are updated using msgmerge). You can perform the second step within Weblate and it will make sure that all pending changes are included prior to this operation.

The second approach can be achieved by using Weblate’s REST API to force Weblate to push all pending changes and lock the translation while you are doing changes on your side.

The script for doing updates can look like this:

# Lock Weblate translation
wlc lock
# Push changes from Weblate to upstream repository
wlc push
# Pull changes from upstream repository to your local copy
git pull
# Update translation files, this example is for Django
./manage.py makemessages --keep-pot -a
git commit -m 'Locale updates' -- locale
# Push changes to upstream repository
git push
# Tell Weblate to pull changes (not needed if Weblate follows your repo
# automatically)
wlc pull
# Unlock translations
wlc unlock

If you have multiple components sharing same repository, you need to lock them all separately:

wlc lock foo/bar
wlc lock foo/baz
wlc lock foo/baj

Note

The example uses Weblate Client, which needs configuration (API keys) to be able to control Weblate remotely. You can also achieve this using any HTTP client instead of wlc, e.g. curl, see Weblate’s REST API.

Weblate Client

Automatically receiving changes from GitHub

Weblate comes with native support for GitHub.

If you are using Hosted Weblate, the recommended approach is to install the Weblate app, that way you will get the correct setup without having to set much up. It can also be used for pushing changes back.

To receive notifications on every push to a GitHub repository, add the Weblate Webhook in the repository settings (Webhooks) as shown on the image below:

For the payload URL, append /hooks/github/ to your Weblate URL, for example for the Hosted Weblate service, this is https://hosted.weblate.org/hooks/github/.

You can leave other values at default settings (Weblate can handle both content types and consumes just the push event).

Automatically receiving changes from Bitbucket

Weblate has support for Bitbucket webhooks, add a webhook which triggers upon repository push, with destination to /hooks/bitbucket/ URL on your Weblate installation (for example https://hosted.weblate.org/hooks/bitbucket/).

Automatically receiving changes from GitLab

Weblate has support for GitLab hooks, add a project webhook with destination to /hooks/gitlab/ URL on your Weblate installation (for example https://hosted.weblate.org/hooks/gitlab/).

Automatically receiving changes from Pagure

New in version 3.3.

Weblate has support for Pagure hooks, add a webhook with destination to /hooks/pagure/ URL on your Weblate installation (for example https://hosted.weblate.org/hooks/pagure/). This can be done in Activate Web-hooks under Project options:

Automatically receiving changes from Azure Repos

New in version 3.8.

Weblate has support for Azure Repos web hooks, add a webhook for Code pushed event with destination to /hooks/azure/ URL on your Weblate installation (for example https://hosted.weblate.org/hooks/azure/). This can be done in Service hooks under Project settings.

Automatically receiving changes from Gitea Repos

New in version 3.9.

Weblate has support for Gitea webhooks, add a Gitea Webhook for Push events event with destination to /hooks/gitea/ URL on your Weblate installation (for example https://hosted.weblate.org/hooks/gitea/). This can be done in Webhooks under repository Settings.

Automatically receiving changes from Gitee Repos

New in version 3.9.

Weblate has support for Gitee webhooks, add a WebHook for Push event with destination to /hooks/gitee/ URL on your Weblate installation (for example https://hosted.weblate.org/hooks/gitee/). This can be done in WebHooks under repository Management.

Automatically updating repositories nightly

Weblate automatically fetches remote repositories nightly to improve performance when merging changes later. You can optionally turn this into doing nightly merges as well, by enabling AUTO_UPDATE.

Pushing changes from Weblate

Each translation component can have a push URL set up (see Repository push URL), and in that case Weblate will be able to push change to the remote repository. Weblate can be also be configured to automatically push changes on every commit (this is default, see Push on commit). If you do not want changes to be pushed automatically, you can do that manually under Repository maintenance or using API via wlc push.

The push options differ based on the Version control integration used, more details are found in that chapter.

In case you do not want direct pushes by Weblate, there is support for GitHub, GitLab, Pagure pull requests or Gerrit reviews, you can activate these by choosing GitHub, GitLab, Gerrit or Pagure as Version control system in Component configuration.

Overall, following options are available with Git, GitHub and GitLab:

Desired setup	Version control system	Repository push URL	Push branch
No push	Git	empty	empty
Push directly	Git	SSH URL	empty
Push to separate branch	Git	SSH URL	Branch name
GitHub pull request from fork	GitHub	empty	empty
GitHub pull request from branch	GitHub	SSH URL 1	Branch name
GitLab merge request from fork	GitLab	empty	empty
GitLab merge request from branch	GitLab	SSH URL 1	Branch name
Pagure merge request from fork	Pagure	empty	empty
Pagure merge request from branch	Pagure	SSH URL 1	Branch name

1(1,2,3): Can be empty in case Source code repository supports pushing.

Note

You can also enable automatic pushing of changes after Weblate commits, this can be done in Push on commit.

See also

See Accessing repositories for setting up SSH keys, and Lazy commits for info about when Weblate decides to commit changes.

Protected branches

If you are using Weblate on protected branch, you can configure it to use pull requests and perform actual review on the translations (what might be problematic for languages you do not know). An alternative approach is to waive this limitation for the Weblate push user.

For example on GitHub this can be done in the repository configuration:

Interacting with others

Weblate makes it easy to interact with others using its API.

See also

Weblate’s REST API

Lazy commits

The behaviour of Weblate is to group commits from the same author into one commit if possible. This greatly reduces the number of commits, however you might need to explicitly tell it to do the commits in case you want to get the VCS repository in sync, e.g. for merge (this is by default allowed for the Managers group, see List of privileges).

The changes in this mode are committed once any of the following conditions are fulfilled:

Somebody else changes an already changed string.
A merge from upstream occurs.
An explicit commit is requested.
Change is older than period defined as Age of changes to commit on Component configuration.

Hint

Commits are created for every component. So in case you have many components you will still see lot of commits. You might utilize Squash Git commits addon in that case.

If you want to commit changes more frequently and without checking of age, you can schedule a regular task to perform a commit:

CELERY_BEAT_SCHEDULE = {
    # Unconditionally commit all changes every 2 minutes
    "commit": {
        "task": "weblate.trans.tasks.commit_pending",
        # Ommiting hours will honor per component settings,
        # otherwise components with no changes older than this
        # won't be committed
        "kwargs": {"hours": 0},
        # How frequently to execute the job in seconds
        "schedule": 120,
    }
}

Processing repository with scripts

The way to customize how Weblate interacts with the repository is Add-ons. Consult Executing scripts from add-on for info on how to execute external scripts through addons.

Keeping translations same across components

Once you have multiple translation components, you might want to ensure that the same strings have same translation. This can be achieved at several levels.

Translation propagation

With Allow translation propagation enabled (what is the default, see Component configuration), all new translations are automatically done in all components with matching strings. Such translations are properly credited to currently translating user in all components.

Note

The translation propagation requires the key to be match for monolingual translation formats, so keep that in mind when creating translation keys.

Consistency check

The Inconsistent check fires whenever the strings are different. You can utilize this to review such differences manually and choose the right translation.

Automatic translation

Automatic translation based on different components can be way to synchronize the translations across components. You can either trigger it manually (see Automatic translation) or make it run automatically on repository update using addon (see Automatic translation).

Licensing translations

You can specify which license translations are contributed under. This is especially important to do if translations are open to the public, to stipulate what they can be used for.

You should specify Component configuration license info. You should avoid requiring a contributor license agreement, though it is possible.

License info

Upon specifying license info (license name and URL), this info is shown in the translation info section of the respective Component configuration.

Usually this is best place to post licensing info if no explicit consent is required. If your project or translation is not libre you most probably need prior consent.

Contributor agreement

If you specify a contributor license agreement, only users who have agreed to it will be able to contribute. This is a clearly visible step when accessing the translation:

The entered text is formatted into paragraphs and external links can be included. HTML markup can not be used.

User licenses

Any user can review all translation licenses of all public projects on the instance from their profile:

Translation process

Suggestion voting

Everyone can add suggestions by default, to be accepted by signed in users. Suggestion voting can be used to make use of a string when more than one signed-in user agrees, by setting up the Component configuration with Suggestion voting to turn on voting, and Autoaccept suggestions to set a threshold for accepted suggestions (this includes a vote from the user making the suggestion if it is cast).

Note

Once automatic acceptance is set up, normal users lose the privilege to directly save translations or accept suggestions. This can be overridden with the Edit string when suggestions are enforced permission.

You can combine these with access control into one of the following setups:

Users suggest and vote for suggestions and a limited group controls what is accepted. - Turn on voting. - Turn off automatic acceptance. - Don’t let users save translations.
Users suggest and vote for suggestions with automatic acceptance once the defined number of them agree. - Turn on voting. - Set the desired number of votes for automatic acceptance.
Optional voting for suggestions. (Can optionally be used by users when they are unsure about a translation by making multiple suggestions.) - Only turn on voting.

Additional info on source strings

Enhance the translation process by adding additional info to the strings including explanations, string priorities, check flags and visual context. Some of that info may be extracted from the translation files and some may be added by editing the additional string info:

Access this directly from the translation interface by clicking the “Edit” icon next to Screenshot context or Flags.

Strings prioritization

New in version 2.0.

String priority can be changed to offer higher priority strings for translation earlier by using the priority flag.

Hint

This can be used to order the flow of translation in a logical manner.

See also

Quality checks

Translation flags

New in version 2.4.

Changed in version 3.3: Previously called Quality checks flags, it no longer configures only checks.

The default set of translation flags is determined by the translation Component configuration and the translation file. However, you might want to use it to customize this per source string.

Explanation

Changed in version 4.1: In previous versions this has been called Extra context.

Use the explanation to clarify scope or usage of the translation. You can use Markdown to include links and other markup.

Visual context for strings

New in version 2.9.

You can upload a screenshot showing a given source string in use within your program. This helps translators understand where it is used, and how it should be translated.

The uploaded screenshot is shown in the translation context sidebar:

In addition to Additional info on source strings, screenshots have a separate management interface under the Tools menu. Upload screenshots, assign them to source strings manually, or use optical character recognition to do so.

Once a screenshot is uploaded, this interface handles management and source string association:

Checks and fixups

Custom automatic fixups

You can also implement your own automatic fixup in addition to the standard ones and include them in AUTOFIX_LIST.

The automatic fixes are powerful, but can also cause damage; be careful when writing one.

For example, the following automatic fixup would replace every occurrence of the string foo in a translation with bar:

To install custom checks, provide a fully-qualified path to the Python class in the AUTOFIX_LIST, see Custom quality checks, addons and auto-fixes.

Customizing behavior using flags

You can fine-tune the behavior of Weblate (mostly checks) for each source string (in source strings review, see Additional info on source strings) or in the Component configuration (Translation flags). Some file formats also allow to specify flags directly in the format (see Supported file formats).

The flags are comma-separated, the parameters are separated with colon. You can use quotes to include whitespace or special chars in the string. For example:

placeholders:"special:value":"other value", regex:.*

Here is a list of flags currently accepted:

rst-text: Treat a text as an reStructuredText document, affects Unchanged translation.
dos-eol: Uses DOS end-of-line markers instead of Unix ones (\r\n instead of \n).
read-only: The string is read-only and should not be edited in Weblate, see Read-only strings.
priority:N: Priority of the string. Higher priority strings are presented first for translation. The default priority is 100, the higher priority a string has, the earlier it is offered for translation.
max-length:N: Limit the maximal length for a string to N characters, see Maximum length of translation.
xml-text: Treat text as XML document, affects XML syntax and XML markup.
font-family:NAME: Define font-family for rendering checks, see Managing fonts.
font-weight:WEIGHT: Define font-weight for rendering checks, see Managing fonts.
font-size:SIZE: Define font-size for rendering checks, see Managing fonts.

icu-flags:FLAGS: Define flags for customizing the behavior of the ICU MessageFormat quality check.
icu-tag-prefix:PREFIX: Set a required prefix for XML tags for the ICU MessageFormat quality check.
placeholders:NAME:NAME2:...: Placeholder strings expected in translation, see Placeholders.
replacements:FROM:TO:FROM2:TO2...: Replacements to perform when checking resulting text parameters (for example in Maximum size of translation or Maximum length of translation). The typical use case for this is to expand placeables to ensure that the text fits even with long values, for example: replacements:%s:"John Doe".
variants:SOURCE: Mark this string as a variant of string with matching source. See String variants.
regex:REGEX: Regular expression to match translation, see Regular expression.

Note

Generally the rule is named ignore-* for any check, using its identifier, so you can use this even for your custom checks.

These flags are understood both in Component configuration settings, per source string settings and in the translation file itself (for example in GNU gettext).

Enforcing checks

New in version 3.11.

You can configure a list of checks which can not be ignored by setting Enforced checks in Component configuration. Each listed check can not be ignored in the user interface and any string failing this check is marked as Needs editing (see Translation states).

Managing fonts

New in version 3.7.

Hint

Fonts uploaded into Weblate are used purely for purposes of the Maximum size of translation check, they do not have an effect in Weblate user interface.

The Maximum size of translation check used to calculate dimensions of the rendered text needs font to be loaded into Weblate and selected using a translation flag (see Customizing behavior using flags).

Weblate font management tool in Fonts under the Manage menu of your translation project provides interface to upload and manage fonts. TrueType or OpenType fonts can be uploaded, set up font-groups and use those in the check.

The font-groups allow you to define different fonts for different languages, which is typically needed for non-latin languages:

The font-groups are identified by name, which can not contain whitespace or special characters, so that it can be easily used in the check definition:

Font-family and style is automatically recognized after uploading them:

You can have a number of fonts loaded into Weblate:

To use the fonts for checking the string length, pass it the appropriate flags (see Customizing behavior using flags). You will probably need the following ones:

max-size:500: Defines maximal width in pixels.
font-family:ubuntu: Defines font group to use by specifying its identifier.
font-size:22: Defines font size in pixels.

Writing own checks

A wide range of quality checks are built-in, (see Quality checks), though they might not cover everything you want to check. The list of performed checks can be adjusted using CHECK_LIST, and you can also add custom checks.

Subclass the weblate.checks.Check
Set a few attributes.
Implement either the check (if you want to deal with plurals in your code) or the check_single method (which does it for you).

Some examples:

To install custom checks, provide a fully-qualified path to the Python class in the CHECK_LIST, see Custom quality checks, addons and auto-fixes.

Checking translation text does not contain “foo”

This is a pretty simple check which just checks whether the translation is missing the string “foo”.

Machine translation

Built-in support for several machine translation services and can be turned on by the administrator using MT_SERVICES for each one. They come subject to their terms of use, so ensure you are allowed to use them how you want.

The source language can be configured at Project configuration.

amaGama

Special installation of tmserver run by the authors of Virtaal.

Turn on this service by adding weblate.machinery.tmserver.AmagamaTranslation to MT_SERVICES.

Apertium

A libre software machine translation platform providing translations to a limited set of languages.

You can list your own class in MT_SERVICES and Weblate will start using that.

Add-ons

New in version 2.19.

Add-ons provide ways to customize and automate the translation workflow. Admins can add and manage add-ons from the Manage ↓ Add-ons menu of each respective translation component.

Hint

You can also configure add-ons using API, DEFAULT_ADDONS, or install_addon.

Built-in add-ons

Automatic translation

New in version 3.9.

Add-on ID

weblate.autotranslate.autotranslate

Configuration

`mode`	Automatic translation mode	Available choices: `suggest` – Add as suggestion `translate` – Add as translation `fuzzy` – Add as needing edit
`filter_type`	Search filter	Available choices: `all` – All strings `nottranslated` – Not translated strings `todo` – Strings needing action `fuzzy` – Strings marked for edit `check:inconsistent` – Failed check: Inconsistent
`auto_source`	Automatic translation source	Available choices: `others` – Other translation components `mt` – Machine translation
`component`	Components	Enter component to use as source, keep blank to use all components in current project.
`engines`	Machine translation engines
`threshold`	Score threshold

Triggers

component update, daily

Automatically translates strings using machine translation or other components.

It is triggered:

When new strings appear in a component.
Once in a month for every component, this can be configured using BACKGROUND_TASKS.

JavaScript localization CDN

New in version 4.2.

Add-on ID

weblate.cdn.cdnjs

Configuration

`threshold`	Translation threshold	Threshold for inclusion of translations.
`css_selector`	CSS selector	CSS selector to detect localizable elements.
`cookie_name`	Language cookie name	Name of cookie which stores language preference.
`files`	Extract strings from HTML files	List of filenames in current repository or remote URLs to parse for translatable strings.

Triggers

daily, repository post-commit, repository post-update

Publishes translations into content delivery network for use in JavaScript or HTML localization.

Can be used to localize static HTML pages, or to load localization in the JavaScript code.

Generates a unique URL for your component you can include in HTML pages to localize them. See Translating HTML and JavaScript using Weblate CDN for more details.

Remove blank strings

New in version 4.4.

Add-on ID: weblate.cleanup.blank
Configuration: This add-on has no configuration.
Triggers: repository post-commit, repository post-update

Removes strings without a translation from translation files.

Use this to not have any empty strings in translation files (for example if your localization library displays them as missing instead of falling back to the source string).

Cleanup translation files

Add-on ID: weblate.cleanup.generic
Configuration: This add-on has no configuration.
Triggers: repository pre-commit, repository post-update

Update all translation files to match the monolingual base file. For most file formats, this means removing stale translation keys no longer present in the base file.

Add missing languages

Add-on ID: weblate.consistency.languages
Configuration: This add-on has no configuration.
Triggers: daily, repository post-add

Ensures a consistent set of languages is used for all components within a project.

Missing languages are checked once every 24 hours, and when new languages are added in Weblate.

Unlike most others, this add-on affects the whole project.

Hint

Auto-translate the newly added strings with Automatic translation.

Component discovery

Add-on ID

weblate.discovery.discovery

Configuration

`match`	Regular expression to match translation files against
`file_format`	File format
`name_template`	Customize the component name
`base_file_template`	Define the monolingual base filename	Leave empty for bilingual translation files.
`new_base_template`	Define the base file for new translations	Filename of file used for creating new translations. For gettext choose .pot file.
`language_regex`	Language filter	Regular expression to filter translation files against when scanning for filemask.
`copy_addons`	Clone addons from the main component to the newly created ones
`remove`	Remove components for inexistant files
`confirm`	I confirm the above matches look correct

Triggers

repository post-update

Automatically adds or removes project components based on file changes in the version control system.

Triggered each time the VCS is updated, and otherwise similar to the import_project management command. This way you can track multiple translation components within one VCS.

The matching is done using regular expressions enabling complex configuration, but some knowledge is required to do so. Some examples for common use cases can be found in the add-on help section.

Once you hit Save, a preview of matching components will be presented, from where you can check whether the configuration actually matches your needs:

Hint

Component discovery add-on uses Weblate internal URLs. It’s a convenient way to share VCS setup between multiple components. Linked components use the local repository of the main component set up by filling weblate://project/main-component into the Source code repository field (in Manage ↓ Settings ↓ Version control system) of each respective component. This saves time with configuration and system resources too.

Search query	`NOT has:label`
Labels to add	recent

Marking all App store metadata files changelog entries read-only
Search query	`language:en AND key:changelogs/`
Translation flags to add	`read-only`

Flag unchanged translations as “Needs editing”

New in version 3.1.

Add-on ID: weblate.flags.same_edit
Configuration: This add-on has no configuration.
Triggers: unit post-create

Whenever a new translatable string is imported from the VCS and it matches a source string, it is flagged as needing editing in Weblate. Especially useful for file formats that include source strings for untranslated strings.

Hint

You might also want to tighthen the Unchanged translation check by adding strict-same flag to Translation flags.

Translation states

Flag new source strings as “Needs editing”

Add-on ID: weblate.flags.source_edit
Configuration: This add-on has no configuration.
Triggers: unit post-create

Translation states

Statistics generator

Add-on ID

weblate.generate.generate

Configuration

`filename`	Name of generated file
`template`	Content of generated file

Triggers

repository pre-commit

Generates a file containing detailed info about the translation status.

You can use a Django template in both filename and content, see Template markup for a detailed markup description.

For example generating a summary file for each translation:

Name of generated file

locale/{{ language_code }}.json

Content

{
   "language": "{{ language_code }}",
   "strings": "{{ stats.all }}",
   "translated": "{{ stats.translated }}",
   "last_changed": "{{ stats.last_changed }}",
   "last_author": "{{ stats.last_author }}",
}

Template markup

Pseudolocale generation

Add-on ID

weblate.generate.pseudolocale

Configuration

`source`	Source strings
`target`	Target translation
`prefix`	String prefix
`suffix`	String suffix

Triggers

component update, daily

Generates a translation by adding prefix and suffix to source strings automatically.

Pseudolocales are useful to find strings that are not prepared for localization. This is done by altering all translatable source strings to make it easy to spot unaltered strings when running the application in the pseudolocale language.

Finding strings whose localized counterparts might not fit the layout is also possible.

Hint

You can use real languages for testing, but there are dedicated pseudolocales available in Weblate - en_XA and ar_XB.

Hint

You can use this add-on to start translation to a new locale of an existing language or similar language. Once you add the translation to the component, follow to the add-on. Example: If you have fr and want to start fr_CA translation, simply set fr as the source, fr_CA as the target, and leave the prefix and suffix blank.

Uninstall the add-on once you have the new translation filled to prevent Weblate from changing the translations made after the copying.

Contributors in comment

Add-on ID: weblate.gettext.authors
Configuration: This add-on has no configuration.
Triggers: repository pre-commit

Updates the comment part of the PO file header to include contributor names and years of contributions.

Component configuration

Post-update repository processing

Can be used to update translation files when the VCS upstream source changes. To achieve this, please remember Weblate only sees files committed to the VCS, so you need to commit changes as a part of the script.

For example with Gulp you can do it using following code:

#! /bin/sh
gulp --gulpfile gulp-i18n-extract.js
git commit -m 'Update source strings' src/languages/en.lang.json

Pre-commit processing of translations

Use the commit script to automatically change a translation before it is committed to the repository.

It is passed as a single parameter consisting of the filename of a current translation.

Translation Memory

New in version 2.20.

Weblate comes with a built-in translation memory consisting of the following:

Manually imported translation memory (see User interface).
Automatically stored translations performed in Weblate (depending on Translation memory scopes).
Automatically imported past translations.

Content in the translation memory can be applied one of two ways:

Manually, Automatic suggestions view while translating.
Automatically, by translating strings using Automatic translation, or Automatic translation addon.

For installation tips, see Weblate Translation Memory, which is turned on by default.

Translation memory scopes

New in version 3.2: In earlier versions translation memory could be only loaded from a file corresponding to the current imported translation memory scope.

The translation memory scopes are there to allow both privacy and sharing of translations, to suit the desired behavior.

Imported translation memory

Importing arbitrary translation memory data using the import_memory command makes memory content available to all users and projects.

Per user translation memory

Stores all user translations automatically in the personal translation memory of each respective user.

Per project translation memory

All translations within a project are automatically stored in a project translation memory only available for this project.

Shared translation memory

All translation within projects with shared translation memory turned on are stored in a shared translation memory available to all projects.

Please consider carefully whether to turn this feature on for shared Weblate installations, as it can have severe implications:

The translations can be used by anybody else.
This might lead to disclosing secret information.

Managing translation memory

User interface

New in version 3.2.

In the basic user interface you can manage per user and per project translation memories. It can be used to download, wipe or import translation memory.

Hint

Translation memory in JSON can be imported into Weblate, TMX is provided for interoperability with other tools.

See also

Weblate Translation Memory Schema

Management interface

Note

This is turned on by default.

HIDE_VERSION

New in version 4.3.1.

Hides version information from unauthenticated users. This also makes all documentation links point to latest version instead of the documentation matching currently installed version.

Hiding version is recommended security practice in some corporations, but it doesn’t prevent attacker to figure out version by probing the behavior.

Note

This is turned off by default.

IP_BEHIND_REVERSE_PROXY

New in version 2.14.

Indicates whether Weblate is running behind a reverse proxy.

If set to True, Weblate gets IP address from a header defined by IP_PROXY_HEADER.

Warning

Ensure you are actually using a reverse proxy and that it sets this header, otherwise users will be able to fake the IP address.

Note

This is not on by default.

IP_PROXY_HEADER

New in version 2.14.

Indicates which header Weblate should obtain the IP address from when IP_BEHIND_REVERSE_PROXY is turned on.

Defaults to HTTP_X_FORWARDED_FOR.

IP_PROXY_OFFSET

New in version 2.14.

Indicates which part of IP_PROXY_HEADER is used as client IP address.

Depending on your setup, this header might consist of several IP addresses, (for example X-Forwarded-For: a, b, client-ip) and you can configure which address from the header is used as client IP address here.

MT_DEEPL_API_URL

Changed in version 4.7: The full API URL is now configured to allow using the free plan. Before, it was only possible to configure the API version using MT_DEEPL_API_VERSION.

API URL to use with the DeepL service. At the time of writing, there is the v1 API as well as a free and a paid version of the v2 API.

https://api.deepl.com/v2/ (default in Weblate): Is meant for API usage on the paid plan, and the subscription is usage-based.
https://api-free.deepl.com/v2/: Is meant for API usage on the free plan, and the subscription is usage-based.
https://api.deepl.com/v1/: Is meant for CAT tools and is usable with a per-user subscription.

Previously Weblate was classified as a CAT tool by DeepL, so it was supposed to use the v1 API, but now is supposed to use the v2 API. Therefore it defaults to v2, and you can change it to v1 in case you have an existing CAT subscription and want Weblate to use that.

The easiest way to find out which one to use is to open an URL like the following in your browser:

https://api.deepl.com/v2/translate?text=Hello&target_lang=FR&auth_key=XXX

Replace the XXX with your auth_key. If you receive a JSON object which contains “Bonjour”, you have the correct URL; if not, try the other three.

This setting affects built-in authentication by e-mail address or through the Python Social Auth (you can whitelist certain back-ends using REGISTRATION_ALLOW_BACKENDS).

Note

If using third-party authentication methods such as LDAP authentication, it just hides the registration form, but new users might still be able to sign in and create accounts.

REPOSITORY_ALERT_THRESHOLD

New in version 4.0.2.

Threshold for triggering an alert for outdated repositories, or ones that contain too many changes. Defaults to 25.

See also

Translation component alerts

SENTRY_DSN

New in version 3.9.

Sentry DSN to use for Collecting error reports.

See also

Django integration for Sentry

SIMPLIFY_LANGUAGES

Use simple language codes for default language/country combinations. For example an fr_FR translation will use the fr language code. This is usually the desired behavior, as it simplifies listing languages for these default combinations.

Turn this off if you want to different translations for each variant.

SITE_DOMAIN

Configures site domain. This is necessary to produce correct absolute links in many scopes (for example activation e-mails, notifications or RSS feeds).

In case Weblate is running on non-standard port, include it here as well.

Examples:

# Production site with domain name
SITE_DOMAIN = "weblate.example.com"

# Local development with IP address and port
SITE_DOMAIN = "127.0.0.1:8000"

Note

This setting should only contain the domain name. For configuring protocol, (enabling and enforcing HTTPS) use ENABLE_HTTPS and for changing URL, use URL_PREFIX.

Hint

On a Docker container, the site domain is configured through WEBLATE_ALLOWED_HOSTS.

SITE_TITLE

Site title to be used for the website and sent e-mails.

SPECIAL_CHARS

Additional characters to include in the visual keyboard, Visual keyboard.

The default value is:

SPECIAL_CHARS = ("\t", "\n", "\u00a0", "…")

SINGLE_PROJECT

New in version 3.8.

Redirects users directly to a project or component instead of showing the dashboard. You can either set it to True and in this case it only works in case there is actually only single project in Weblate. Alternatively set the project slug, and it will redirect unconditionally to this project.

Changed in version 3.11: The setting now also accepts a project slug, to force displaying that single project.

Example:

SINGLE_PROJECT = "test"

SSH_EXTRA_ARGS

New in version 4.9.

Allows to add custom parameters when Weblate is invoking SSH. This is useful when connecting to servers using legacy encryption or other non-standard features.

For example when SSH connection in Weblate fails with Unable to negotiate with legacyhost: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1, you can enable that using:

SSH_EXTRA_ARGS = "-oKexAlgorithms=+diffie-hellman-group1-sha1"

Hint

The string is evaluated by shell, so make sure to quote any whitespace and special characters.

See also

OpenSSH Legacy Options

STATUS_URL

The URL where your Weblate instance reports its status.

SUGGESTION_CLEANUP_DAYS

New in version 3.2.1.

Automatically deletes suggestions after a given number of days. Defaults to None, meaning no deletions.

UPDATE_LANGUAGES

New in version 4.3.2.

Controls whether languages database should be updated when running database migration and is enabled by default. This setting has no effect on invocation of setuplang.

See also

Built-in language definitions

URL_PREFIX

This setting allows you to run Weblate under some path (otherwise it relies on being run from the webserver root).

Note

To use this setting, you also need to configure your server to strip this prefix. For example with WSGI, this can be achieved by setting WSGIScriptAlias.

Hint

The prefix should start with a /.

Example:

URL_PREFIX = "/translations"

Note

This setting does not work with Django’s built-in server, you would have to adjust urls.py to contain this prefix.

VCS_BACKENDS

Configuration of available VCS backends.

Note

Weblate tries to use all supported back-ends you have the tools for.

Hint

You can limit choices or add custom VCS back-ends by using this.

VCS_BACKENDS = ("weblate.vcs.git.GitRepository",)

See also

Version control integration

VCS_CLONE_DEPTH

New in version 3.10.2.

Configures how deep cloning of repositories Weblate should do.

Note

Currently this is only supported in Git. By default Weblate does shallow clones of the repositories to make cloning faster and save disk space. Depending on your usage (for example when using custom Add-ons), you might want to increase the depth or turn off shallow clones completely by setting this to 0.

Hint

In case you get fatal: protocol error: expected old/new/ref, got 'shallow <commit hash>' error when pushing from Weblate, turn off shallow clones completely by setting:

VCS_CLONE_DEPTH = 0

WEBLATE_ADDONS

List of addons available for use. To use them, they have to be enabled for a given translation component. By default this includes all built-in addons, when extending the list you will probably want to keep existing ones enabled, for example:

WEBLATE_ADDONS = (
    # Built-in addons
    "weblate.addons.gettext.GenerateMoAddon",
    "weblate.addons.gettext.UpdateLinguasAddon",
    "weblate.addons.gettext.UpdateConfigureAddon",
    "weblate.addons.gettext.MsgmergeAddon",
    "weblate.addons.gettext.GettextCustomizeAddon",
    "weblate.addons.gettext.GettextAuthorComments",
    "weblate.addons.cleanup.CleanupAddon",
    "weblate.addons.consistency.LangaugeConsistencyAddon",
    "weblate.addons.discovery.DiscoveryAddon",
    "weblate.addons.flags.SourceEditAddon",
    "weblate.addons.flags.TargetEditAddon",
    "weblate.addons.flags.SameEditAddon",
    "weblate.addons.flags.BulkEditAddon",
    "weblate.addons.generate.GenerateFileAddon",
    "weblate.addons.json.JSONCustomizeAddon",
    "weblate.addons.properties.PropertiesSortAddon",
    "weblate.addons.git.GitSquashAddon",
    "weblate.addons.removal.RemoveComments",
    "weblate.addons.removal.RemoveSuggestions",
    "weblate.addons.resx.ResxUpdateAddon",
    "weblate.addons.autotranslate.AutoTranslateAddon",
    "weblate.addons.yaml.YAMLCustomizeAddon",
    "weblate.addons.cdn.CDNJSAddon",
    # Add-on you want to include
    "weblate.addons.example.ExampleAddon",
)

Note

Removing the addon from the list does not uninstall it from the components. Weblate will crash in that case. Please uninstall addon from all components prior to removing it from this list.

See also

Add-ons, DEFAULT_ADDONS

WEBLATE_EXPORTERS

New in version 4.2.

List of a available exporters offering downloading translations or glossaries in various file formats.

See also

Supported file formats

WEBLATE_FORMATS

New in version 3.0.

List of file formats available for use.

Note

The default list already has the common formats.

See also

Supported file formats

WEBLATE_GPG_IDENTITY

New in version 3.1.

Identity used by Weblate to sign Git commits, for example:

WEBLATE_GPG_IDENTITY = "Weblate <weblate@example.com>"

The Weblate GPG keyring is searched for a matching key (home/.gnupg under DATA_DIR). If not found, a key is generated, please check Signing Git commits with GnuPG for more details.

See also

Signing Git commits with GnuPG

WEBSITE_REQUIRED

Defines whether Project website has to be specified when creating a project. Turned on by default as that suits public server setups.

Management commands

Note

Running management commands under a different user than the one running your webserver can result in files getting wrong permissions, please check Filesystem permissions for more details.

You will find basic management commands (available as ./manage.py in the Django sources, or as an extended set in a script called weblate installable atop Weblate).

Invoking management commands

As mentioned before, invocation depends on how you installed Weblate.

If using virtualenv for Weblate, you can either specify the full path to weblate, or activate the virtualenv prior to invoking it:

# Direct invocation
~/weblate-env/bin/weblate

# Activating virtualenv adds it to search path
. ~/weblate-env/bin/activate
weblate

If you are using source code directly (either from a tarball or Git checkout), the management script is ./manage.py available in the Weblate sources. To run it:

python ./manage.py list_versions

If you’ve installed Weblate using the pip or pip3 installer, or by using the ./setup.py script, the weblate is installed to your path (or virtualenv path), from where you can use it to control Weblate:

weblate list_versions

For the Docker image, the script is installed like above, and you can run it using docker exec:

docker exec --user weblate <container> weblate list_versions

For docker-compose the process is similar, you just have to use docker-compose exec:

docker-compose exec --user weblate weblate weblate list_versions

In case you need to pass it a file, you can temporary add a volume:

docker-compose exec --user weblate /tmp:/tmp weblate weblate importusers /tmp/users.json

add_suggestions

weblate add_suggestions <project> <component> <language> <file>

New in version 2.5.

Imports a translation from the file to use as a suggestion for the given translation. It skips duplicated translations; only different ones are added.

--author USER@EXAMPLE.COM: E-mail of author for the suggestions. This user has to exist prior to importing (you can create one in the admin interface if needed).

Example:

weblate --author michal@cihar.com add_suggestions weblate application cs /tmp/suggestions-cs.po

auto_translate

weblate auto_translate <project> <component> <language>

New in version 2.5.

Changed in version 4.6: Added parameter for translation mode.

Performs automatic translation based on other component translations.

--source PROJECT/COMPONENT: Specifies the component to use as source available for translation. If not specified all components in the project are used.

--user USERNAME: Specify username listed as author of the translations. “Anonymous user” is used if not specified.

--overwrite: Whether to overwrite existing translations.

--inconsistent: Whether to overwrite existing translations that are inconsistent (see Inconsistent).

--add: Automatically add language if a given translation does not exist.

--mt MT: Use machine translation instead of other components as machine translations.

--threshold THRESHOLD: Similarity threshold for machine translation, defaults to 80.

--mode MODE: Specify translation mode, default is translate but fuzzy or suggest can be used.

Example:

weblate auto_translate --user nijel --inconsistent --source weblate/application weblate website cs

Automatic translation

celery_queues

weblate celery_queues

New in version 3.7.

Displays length of Celery task queues.

checkgit

weblate checkgit <project|project/component>

Prints current state of the back-end Git repository.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

commitgit

weblate commitgit <project|project/component>

Commits any possible pending changes to the back-end Git repository.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

commit_pending

weblate commit_pending <project|project/component>

Commits pending changes older than a given age.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

--age HOURS: Age in hours for committing. If not specified the value configured in Component configuration is used.

Note

This is automatically performed in the background by Weblate, so there no real need to invoke this manually, besides forcing an earlier commit than specified by Component configuration.

cleanuptrans

weblate cleanuptrans

Cleans up orphaned checks and translation suggestions. There is normally no need to run this manually, as the cleanups happen automatically in the background.

See also

Running maintenance tasks

cleanup_ssh_keys

weblate cleanup_ssh_keys

New in version 4.9.1.

Performs cleanup of stored SSH host keys:

Removes deprecated RSA keys for GitHub which might cause issues connecting to GitHub.
Removes duplicate entries in host keys.

See also

:ref`ssh-repos`

createadmin

weblate createadmin

Creates an admin account with a random password, unless it is specified.

--password PASSWORD: Provides a password on the command-line, to not generate a random one.

--no-password: Do not set password, this can be useful with –update.

--username USERNAME: Use the given name instead of admin.

--email USER@EXAMPLE.COM: Specify the admin e-mail address.

--name: Specify the admin name (visible).

--update: Update the existing user (you can use this to change passwords).

Changed in version 2.9: Added parameters --username, --email, --name and --update.

dump_memory

weblate dump_memory

New in version 2.20.

Export a JSON file containing Weblate Translation Memory content.

dumpuserdata

weblate dumpuserdata <file.json>

Dumps userdata to a file for later use by importuserdata

Hint

This comes in handy when migrating or merging Weblate instances.

import_demo

weblate import_demo

New in version 4.1.

Creates a demo project with components based on <https://github.com/WeblateOrg/demo>.

This can be useful when developing Weblate.

import_json

weblate import_json <json-file>

New in version 2.7.

Batch import of components based on JSON data.

The imported JSON file structure pretty much corresponds to the component object (see GET /api/components/(string:project)/(string:component)/). You have to include the name and filemask fields.

--project PROJECT: Specifies where the components will be imported from.

--main-component COMPONENT: Use the given VCS repository from this component for all of them.

--ignore: Skip (already) imported components.

--update: Update (already) imported components.

Changed in version 2.9: The parameters --ignore and --update are there to deal with already imported components.

Example of JSON file:

[
  {
    "slug": "po",
    "name": "Gettext PO",
    "file_format": "po",
    "filemask": "po/*.po",
    "new_lang": "none"
  },
  {
    "name": "Android",
    "filemask": "android/values-*/strings.xml",
    "template": "android/values/strings.xml",
    "repo": "weblate://test/test",
    "file_format": "aresource"
  }
]

import_memory

import_memory

weblate import_memory <file>

New in version 2.20.

Imports a TMX or JSON file into the Weblate translation memory.

--language-map LANGMAP

Allows mapping languages in the TMX to the Weblate translation memory. The language codes are mapped after normalization usually done by Weblate.

--language-map en_US:en will for example import all en_US strings as en ones.

This can be useful in case your TMX file locales happen not to match what you use in Weblate.

import_project

weblate import_project <project> <gitrepo> <branch> <filemask>

Changed in version 3.0: The import_project command is now based on the Component discovery add-on, leading to some changes in behavior and what parameters are accepted.

Batch imports components into project based on filemask.

<project> names an existing project, into which the components are to be imported.

The <gitrepo> defines the Git repository URL to use, and <branch> signifies the Git branch. To import additional translation components from an existing Weblate component, use a weblate://<project>/<component> URL for the <gitrepo>.

The <filemask> defines file discovery for the repository. It can be either be made simple using wildcards, or it can use the full power of regular expressions.

The simple matching uses ** for component name and * for language, for example: **/*.po

The regular expression has to contain groups named component and language. For example: (?P<language>[^/]*)/(?P<component>[^-/]*)\.po

The import matches existing components based on files and adds the ones that do not exist. It does not change already existing ones.

--name-template TEMPLATE

Customize the name of a component using Django template syntax.

For example: Documentation: {{ component }}

--base-file-template TEMPLATE

Customize the base file for monolingual translations.

For example: {{ component }}/res/values/string.xml

--new-base-template TEMPLATE

Customize the base file for addition of new translations.

For example: {{ component }}/ts/en.ts

--file-format FORMAT: You can also specify the file format to use (see Supported file formats), the default is auto-detection.

--language-regex REGEX: You can specify language filtering (see Component configuration) with this parameter. It has to be a valid regular expression.

--main-component: You can specify which component will be chosen as the main one—the one actually containing the VCS repository.

--license NAME: Specify the overall, project or component translation license.

--license-url URL: Specify the URL where the translation license is to be found.

--vcs NAME: In case you need to specify which version control system to use, you can do it here. The default version control is Git.

To give you some examples, let’s try importing two projects.

First The Debian Handbook translations, where each language has separate a folder with the translations of each chapter:

weblate import_project \
    debian-handbook \
    git://anonscm.debian.org/debian-handbook/debian-handbook.git \
    squeeze/master \
    '*/**.po'

Then the Tanaguru tool, where the file format needs be specified, along with the base file template, and how all components and translations are located in single folder:

weblate import_project \
    --file-format=properties \
    --base-file-template=web-app/tgol-web-app/src/main/resources/i18n/%s-I18N.properties \
    tanaguru \
    https://github.com/Tanaguru/Tanaguru \
    master \
    web-app/tgol-web-app/src/main/resources/i18n/**-I18N_*.properties

More complex example of parsing of filenames to get the correct component and language out of a filename like src/security/Numerous_security_holes_in_0.10.1.de.po:

weblate import_project \
    tails \
    git://git.tails.boum.org/tails master \
    'wiki/src/security/(?P<component>.*)\.(?P<language>[^.]*)\.po$'

Filtering only translations in a chosen language:

./manage import_project \
    --language-regex '^(cs|sk)$' \
    weblate \
    https://github.com/WeblateOrg/weblate.git \
    'weblate/locale/*/LC_MESSAGES/**.po'

Importing Sphinx documentation split to multiple files:

$ weblate import_project --name-template 'Documentation: %s' \
    --file-format po \
    project https://github.com/project/docs.git master \
    'docs/locale/*/LC_MESSAGES/**.po'

Importing Sphinx documentation split to multiple files and directories:

$ weblate import_project --name-template 'Directory 1: %s' \
    --file-format po \
    project https://github.com/project/docs.git master \
    'docs/locale/*/LC_MESSAGES/dir1/**.po'
$ weblate import_project --name-template 'Directory 2: %s' \
    --file-format po \
    project https://github.com/project/docs.git master \
    'docs/locale/*/LC_MESSAGES/dir2/**.po'

More detailed examples can be found in the Starting with internationalization chapter, alternatively you might want to use import_json.

importuserdata

weblate importuserdata <file.json>

Imports user data from a file created by dumpuserdata

importusers

weblate importusers --check <file.json>

Imports users from JSON dump of the Django auth_users database.

--check: With this option it will just check whether a given file can be imported and report possible conflicts arising from usernames or e-mails.

You can dump users from the existing Django installation using:

weblate dumpdata auth.User > users.json

install_addon

New in version 3.2.

weblate install_addon --addon ADDON <project|project/component>

Installs an add-on to a set of components.

--addon ADDON: Name of the add-on to install. For example weblate.gettext.customize.

--configuration CONFIG: JSON encoded configuration of an add-on.

--update: Update the existing add-on configuration.

You can either define which project or component to install the add-on in (for example weblate/application), or use --all to include all existing components.

To install Customize gettext output for all components:

weblate install_addon --addon weblate.gettext.customize --config '{"width": -1}' --update --all

list_translators

weblate list_translators <project|project/component>

Lists translators by contributed language for the given project:

[French]
Jean Dupont <jean.dupont@example.com>
[English]
John Doe <jd@example.com>

--language-code: List names by language code instead of language name.

You can either define which project or component to use (for example weblate/application), or use --all to list translators from all existing components.

list_versions

weblate list_versions

Lists all Weblate dependencies and their versions.

loadpo

weblate loadpo <project|project/component>

Reloads translations from disk (for example in case you have done some updates in the VCS repository).

--force: Force update, even if the files should be up-to-date.

--lang LANGUAGE: Limit processing to a single language.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

Note

You seldom need to invoke this, Weblate will automatically load changed files for every VCS update. This is needed in case you manually changed an underlying Weblate VCS repository or in some special cases following an upgrade.

lock_translation

weblate lock_translation <project|project/component>

Prevents further translation of a component.

Hint

Useful in case you want to do some maintenance on the underlying repository.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

See also

unlock_translation

move_language

weblate move_language source target

New in version 3.0.

Allows you to merge language content. This is useful when updating to a new version which contains aliases for previously unknown languages that have been created with the (generated) suffix. It moves all content from the source language to the target one.

Example:

weblate move_language cze cs

After moving the content, you should check whether there is anything left (this is subject to race conditions when somebody updates the repository meanwhile) and remove the (generated) language.

pushgit

weblate pushgit <project|project/component>

Pushes committed changes to the upstream VCS repository.

--force-commit: Force commits any pending changes, prior to pushing.

Note

Weblate pushes changes automatically if Push on commit in Component configuration is turned on, which is the default.

unlock_translation

weblate unlock_translation <project|project/component>

Unlocks a given component, making it available for translation.

Hint

Useful in case you want to do some maintenance on the underlying repository.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

See also

lock_translation

setupgroups

weblate setupgroups

Configures default groups and optionally assigns all users to that default group.

--no-privs-update: Turns off automatic updating of existing groups (only adds new ones).

--no-projects-update: Prevents automatic updates of groups for existing projects. This allows adding newly added groups to existing projects, see Project access control.

See also

List of privileges

updategit

weblate updategit <project|project/component>

Fetches remote VCS repositories and updates the internal cache.

You can either define which project or component to update (for example weblate/application), or use --all to update all existing components.

Note

Usually it is better to configure hooks in the repository to trigger Notification hooks, instead of regular polling by updategit.

Announcements

Changed in version 4.0: In prior releases this feature was called whiteboard messages.

Provide info to your translators by posting announcements, site-wide, per project, component, or language.

Announce the purpose, deadlines, status, or specify targets for translation.

The users will receive notification on the announcements for watched projects (unless they opt out).

This can be useful for various things from announcing the purpose of the website to specifying targets for translations.

The announcements can posted on each level in the Manage menu, using Post announcement:

Image showing a message that reads: "Translations will be used only if they reach 60%" atop the dashboard view.

It can be also added using the admin interface:

The announcements are then shown based on their specified context:

No context specified

Shown on dashboard (landing page).

Project specified

Shown within the project, including all its components and translations.

Component specified

Shown for a given component and all its translations.

Language specified

Shown on the language overview and all translations in that language.

This is how it looks on the language overview page:

Image showing a message that reads: "Czech translators rock!" atop the Czech language overview.

Component Lists

Specify multiple lists of components to appear as options on the user dashboard, from which users can pick one as their default view. See Dashboard to learn more.

Changed in version 2.20: A status will be presented for each component list presented on the dashboard.

The names and content of component lists can be specified in the admin interface, in Component lists section. Each component list must have a name that is displayed to the user, and a slug representing it in the URL.

Changed in version 2.13: Change dashboard settings for anonymous users from the admin interface, altering what dashboard is presented to unauthenticated users.

Automatic component lists

New in version 2.13.

Add components to the list automatically based on their slug by creating Automatic component list assignment rules.

Useful for maintaining component lists for large installations, or in case you want to have one component list with all components on your Weblate installation.

Hint

Make a component list containing all the components of your Weblate installation.

1. Define Automatic component list assignment with ^.*$ as regular expression in both the project and the component fields, as shown on this image:

Image showing the Weblate administration panel with the above configuration filled in.

Optional Weblate modules

Several optional modules are available for your setup.

Git exporter

New in version 2.10.

Provides you read-only access to the underlying Git repository using HTTP(S).

Installation

Add weblate.gitexport to installed apps in settings.py:

INSTALLED_APPS += ("weblate.gitexport",)

Export existing repositories by migrating your database after installation:

weblate migrate

Usage

The module automatically hooks into Weblate and sets the exported repository URL in the Component configuration. The repositories are accessible under the /git/ part of the Weblate URL, for example https://example.org/git/weblate/main/.

Repositories for publicly available projects can be cloned without authentication:

git clone 'https://example.org/git/weblate/main/'

Access to browse the repositories with restricted access (with Private access control or when REQUIRE_LOGIN is enabled) requires an API token which can be obtained in your user profile:

git clone 'https://user:KEY@example.org/git/weblate/main/'

Hint

By default members or Users group and anonymous user have access to the repositories for public projects via Access repository and Power user roles.

Billing

New in version 2.4.

This is used on Hosted Weblate to define billing plans, track invoices and usage limits.

Installation

1. Add weblate.billing to installed apps in settings.py:

INSTALLED_APPS += ("weblate.billing",)

Run the database migration to optionally install additional database structures for the module:

weblate migrate

Usage

After installation you can control billing in the admin interface. Users with billing enabled will get new Billing tab in their User profile.

The billing module additionally allows project admins to create new projects and components without being superusers (see Adding translation projects and components). This is possible when following conditions are met:

The billing is in its configured limits (any overusage results in blocking of project/component creation) and paid (if its price is non zero)
The user is admin of existing project with billing or user is owner of billing (the latter is necessary when creating new billing for users to be able to import new projects).

Upon project creation user is able to choose which billing should be charged for the project in case he has access to more of them.

Legal

New in version 2.15.

This is used on Hosted Weblate to provide required legal documents. It comes provided with blank documents, and you are expected to fill out the following templates in the documents:

legal/documents/tos.html: Terms of service document
legal/documents/privacy.html: Privacy policy document
legal/documents/summary.html: Short overview of the terms of service and privacy policy

Note

Legal documents for the Hosted Weblate service are available in this Git repository <https://github.com/WeblateOrg/wllegal/tree/main/wllegal/templates/legal/documents>.

Most likely these will not be directly usable to you, but might come in handy as a starting point if adjusted to meet your needs.

Installation

1. Add weblate.legal to installed apps in settings.py:

INSTALLED_APPS += ("weblate.legal",)

# Optional:

# Social auth pipeline to confirm TOS upon registration/subsequent sign in
SOCIAL_AUTH_PIPELINE += ("weblate.legal.pipeline.tos_confirm",)

# Middleware to enforce TOS confirmation of signed in users
MIDDLEWARE += [
    "weblate.legal.middleware.RequireTOSMiddleware",
]

Run the database migration to optionally install additional database structures for the module:

weblate migrate

Edit the legal documents in the weblate/legal/templates/legal/ folder to match your service.

Usage

After installation and editing, the legal documents are shown in the Weblate UI.

Avatars

Avatars are downloaded and cached server-side to reduce information leaks to the sites serving them by default. The built-in support for fetching avatars from e-mails addresses configured for it can be turned off using ENABLE_AVATARS.

Weblate currently supports:

Spam protection

You can protect against spamming by users by using the Akismet service.

Install the akismet Python module (this is already included in the official Docker image).
Obtain the Akismet API key.
Store it as AKISMET_API_KEY or WEBLATE_AKISMET_API_KEY in Docker.

Following content is sent to Akismet for checking:

Suggestions from unauthenticated users
Project and component descriptions and links

Note

This (among other things) relies on IP address of the client, please see Running behind reverse proxy for properly configuring that.

Signing Git commits with GnuPG

New in version 3.1.

All commits can be signed by the GnuPG key of the Weblate instance.

1. Turn on WEBLATE_GPG_IDENTITY. (Weblate will generate a GnuPG key when needed and will use it to sign all translation commits.)

This feature needs GnuPG 2.1 or newer installed.

You can find the key in the DATA_DIR and the public key is shown on the “About” page:

2. Alternatively you can also import existing keys into Weblate, just set HOME=$DATA_DIR/home when invoking gpg.

See also

WEBLATE_GPG_IDENTITY

Rate limiting

Changed in version 3.2: The rate limiting now accepts more fine-grained configuration.

Changed in version 4.6: The rate limiting no longer applies to superusers.

Several operations in Weblate are rate limited. At most RATELIMIT_ATTEMPTS attempts are allowed within RATELIMIT_WINDOW seconds. The user is then blocked for RATELIMIT_LOCKOUT. There are also settings specific to scopes, for example RATELIMIT_CONTACT_ATTEMPTS or RATELIMIT_TRANSLATE_ATTEMPTS. The table below is a full list of available scopes.

The following operations are subject to rate limiting:

Name	Scope	Allowed attempts	Ratelimit window	Lockout period
Registration	`REGISTRATION`	5	300	600
Sending message to admins	`MESSAGE`	5	300	600
Password authentication on sign in	`LOGIN`	5	300	600
Sitewide search	`SEARCH`	6	60	60
Translating	`TRANSLATE`	30	60	600
Adding to glossary	`GLOSSARY`	30	60	600
Starting translation into a new language	`LANGUAGE`	2	300	600
Creating new project	`PROJECT`	5	600	600

If a user fails to log in AUTH_LOCK_ATTEMPTS times, password authentication will be turned off on the account until having gone through the process of having its password reset.

The settings can be also applied in the Docker container by adding WEBLATE_ prefix to the setting name, for example RATELIMIT_ATTEMPTS becomes WEBLATE_RATELIMIT_ATTEMPTS.

The API has separate rate limiting settings, see API rate limiting.

Fedora Messaging integration

Fedora Messaging is AMQP-based publisher for all changes happening in Weblate. You can hook additional services on changes happening in Weblate using this.

The Fedora Messaging integration is available as a separate Python module weblate-fedora-messaging. Please see <https://github.com/WeblateOrg/fedora_messaging/> for setup instructions.

Customizing Weblate

Extend and customize using Django and Python. Contribute your changes upstream so that everybody can benefit. This reduces your maintenance costs; code in Weblate is taken care of when changing internal interfaces or refactoring the code.

Warning

Neither internal interfaces nor templates are considered a stable API. Please review your own customizations for every upgrade, the interfaces or their semantics might change without notice.

Creating a Python module

If you are not familiar with Python, you might want to look into Python For Beginners, explaining the basics and pointing to further tutorials.

To write some custom Python code (called a module), a place to store it is needed, either in the system path (usually something like /usr/lib/python3.7/site-packages/) or in the Weblate directory, which is also added to the interpreter search path.

Better yet, turn your customization into a proper Python package:

Create a folder for your package (we will use weblate_customization).

Within it, create a setup.py file to describe the package:

from setuptools import setup

setup(
    name="weblate_customization",
    version="0.0.1",
    author="Your name",
    author_email="yourname@example.com",
    description="Sample Custom check for Weblate.",
    license="GPLv3+",
    keywords="Weblate check example",
    packages=["weblate_customization"],
)

Create a folder for the Python module (also called weblate_customization) for the customization code.
Within it, create a __init__.py file to make sure Python can import the module.
This package can now be installed using pip install -e. More info to be found in “Editable” Installs.
Once installed, the module can be used in the Weblate configuration (for example weblate_customization.checks.FooCheck).

Your module structure should look like this:

weblate_customization
├── setup.py
└── weblate_customization
    ├── __init__.py
    ├── addons.py
    └── checks.py

You can find an example of customizing Weblate at <https://github.com/WeblateOrg/customize-example>, it covers all the topics described below.

Changing the logo

Create a simple Django app containing the static files you want to overwrite (see Creating a Python module).

Branding appears in the following files:

icons/weblate.svg
Logo shown in the navigation bar.

logo-*.png
Web icons depending on screen resolution and web-browser.

favicon.ico
Web icon used by legacy browsers.

weblate-*.png
Avatars for bots or anonymous users. Some web-browsers use these as shortcut icons.

email-logo.png
Used in notifications e-mails.

Add it to INSTALLED_APPS:

INSTALLED_APPS = (
    # Add your customization as first
    "weblate_customization",
    # Weblate apps are here…
)

Run weblate collectstatic --noinput, to collect static files served to clients.

Custom quality checks, addons and auto-fixes

To install your code for Custom automatic fixups, Writing own checks or Writing add-on in Weblate:

Place the files into your Python module containing the Weblate customization (see Creating a Python module).
Add its fully-qualified path to the Python class in the dedicated settings (WEBLATE_ADDONS, CHECK_LIST or AUTOFIX_LIST):

# Checks
CHECK_LIST += ("weblate_customization.checks.FooCheck",)

# Autofixes
AUTOFIX_LIST += ("weblate_customization.autofix.FooFixer",)

# Add-ons
WEBLATE_ADDONS += ("weblate_customization.addons.ExamplePreAddon",)

Management interface

The management interface offer administration settings under the /manage/ URL. It is available for users signed in with admin privileges, accessible by using the wrench icon top right:

It includes basic overview of your Weblate:

Support status, see Getting support for Weblate
Backups, see Backing up and moving Weblate
Shared translation memory, see Translation Memory
Performance report to review Weblate health and length of Celery queues
SSH keys management, see SSH repositories
Alerts overview for all components, see Translation component alerts

The Django admin interface

Warning

Will be removed in the future, as its use is discouraged—most features can be managed directly in Weblate.

Here you can manage objects stored in the database, such as users, translations and other settings:

In the Reports section, you can check the status of your site, tweak it for Production setup, or manage SSH keys used to access Accessing repositories.

Manage database objects under any of the sections. The most interesting one is probably Weblate translations, where you can manage translatable projects, see Project configuration and Component configuration.

Weblate languages holds language definitions, explained further in Language definitions.

Adding a project

Adding a project serves as container for all components. Usually you create one project for one piece of software, or book (See Project configuration for info on individual parameters):

See also

Project configuration

Bilingual components

Once you have added a project, translation components can be added to it. (See Component configuration for info regarding individual parameters):

Monolingual components

For easier translation of these, provide a template file containing the mapping of message IDs to its respective source language (usually English). (See Component configuration for info regarding individual parameters):

Getting support for Weblate

Weblate is copylefted libre software with community support. Subscribers receive priority support at no extra charge. Prepaid help packages are available for everyone. You can find more info about current support offerings at <https://weblate.org/support/>.

Integrating support

New in version 3.8.

Purchased support packages can optionally be integrated into your Weblate subscription management interface, from where you will find a link to it. Basic instance details about your installation are also reported back to Weblate this way.

Data submitted to the Weblate

URL where your Weblate instance is configured
Your site title
The Weblate version you are running
Tallies of some objects in your Weblate database (projects, components, languages, source strings and users)
The public SSH key of your instance

Additionally, when Discover Weblate is turned on:

List of public projects (name, URL and website)

No other data is submitted.

Integration services

See if your support package is still valid
Weblate provisioned backup storage
Discover Weblate

Hint

Purchased support packages are already activated upon purchase, and can be used without integrating them.

Discover Weblate

New in version 4.5.2.

Note

This feature is currently in early beta.

Discover Weblate is an opt-in service that makes it easier for users to find Weblate servers and communities. Users can browse registered services on <https://weblate.org/discover/>, and find there projects to contribute.

Getting listed

Hint

Participating in Discover Weblate makes Weblate submit some information about your server, please see Data submitted to the Weblate.

To list your server with an active support subscription (see Integrating support) in Discover Weblate all you need to do is turn this on in the management panel:

Listing your server without a support subscription in Discover Weblate:

Register yourself at <https://weblate.org/user/>
Register your Weblate server in the discovery database at <https://weblate.org/subscription/discovery/>
Confirm the service activation in your Weblate and turn on the discovery listing in your Weblate management page using Enable discovery button:

Customizing listing

You can customize the listing by providing a text and image (570 x 260 pixels) at <https://weblate.org/user/>.

Legal documents

Note

Herein you will find various legal information you might need to operate Weblate in certain legal jurisdictions. It is provided as a means of guidance, without any warranty of accuracy or correctness. It is ultimately your responsibility to ensure that your use of Weblate complies with all applicable laws and regulations.

ITAR and other export controls

Weblate can be run within your own datacenter or virtual private cloud. As such, it can be used to store ITAR or other export-controlled information, however, end users are responsible for ensuring such compliance.

The Hosted Weblate service has not been audited for compliance with ITAR or other export controls, and does not currently offer the ability to restrict translations access by country.

US encryption controls

Weblate does not contain any cryptographic code, but might be subject export controls as it uses third party components utilizing cryptography for authentication, data-integrity and -confidentiality.

Most likely Weblate would be classified as ECCN 5D002 or 5D992 and, as publicly available libre software, it should not be subject to EAR (see Encryption items NOT Subject to the EAR).

Software components used by Weblate (listing only components related to cryptographic function):

Python: See https://wiki.python.org/moin/PythonSoftwareFoundationLicenseFaq#Is_Python_subject_to_export_laws.3F
GnuPG: Optionally used by Weblate
Git: Optionally used by Weblate
curl: Used by Git
OpenSSL: Used by Python and cURL

The strength of encryption keys depends on the configuration of Weblate and the third party components it interacts with, but in any decent setup it will include all export restricted cryptographic functions:

In excess of 56 bits for a symmetric algorithm
Factorisation of integers in excess of 512 bits for an asymmetric algorithm
Computation of discrete logarithms in a multiplicative group of a finite field of size greater than 512 bits for an asymmetric algorithm
Discrete logarithms in a group different than above in excess of 112 bits for an asymmetric algorithm

Weblate doesn’t have any cryptographic activation feature, but it can be configured in a way where no cryptography code would be involved. The cryptographic features include:

Accessing remote servers using secure protocols (HTTPS)
Generating signatures for code commits (PGP)

Starting with internationalization

Have a project and want to translate it into several languages? This guide will help you do so. Several typical situations are showcased, but most of the examples are generic and can be applied to other scenarios as well.

Before translating any software, you should realize that languages around the world are really different and you should not make any assumption based on your experience. For most of languages it will look weird if you try to concatenate a sentence out of translated segments. You also should properly handle plural forms because many languages have complex rules for that and the internationalization framework you end up using should support this.

Last but not least, sometimes it might be necessary to add some context to the translated string. Imagine a translator would get string Sun to translate. Without context most people would translate that as our closest star, but it might be actually used as an abbreviation for Sunday.

Choosing internationalization framework

Choose whatever is standard on your platform, try to avoid reinventing the wheel by creating your own framework to handle localizations. Weblate supports most of the widely used frameworks, see Supported file formats for more information (especially Translation types capabilities).

Our personal recommendation for some platforms is in the following table. This is based on our experience, but that can not cover all use cases, so always consider your environment when doing the choice.

Platform	Recommended format
Android	Android string resources
iOS	Apple iOS strings
Qt	Qt Linguist .ts
Python	GNU gettext
PHP	GNU gettext 1
C/C++	GNU gettext
C#	.XML resource files
Perl	GNU gettext
Ruby	Ruby YAML files
Web extensions	WebExtension JSON
Java	XLIFF 2
JavaScript	JSON i18next files 3

1: The native Gettext support in PHP is buggy and often missing on Windows builds, it is recommended to use third party library motranslator instead.
2: You can also use Java properties if plurals are not needed.
3: You can also use plain JSON files if plurals are not needed.

The more detailed workflow for some formats is described in following chapters:

Integrating with Weblate

Weblate basics

Project and component structure

Importing localization project into Weblate

Weblate has been developed with VCS integration in mind as it’s core feature, so the easiest way is to grant Weblate the access to your repository. The import process will guide you through configuring your translations into components.

Alternatively, you can use Weblate to set up a local repository containing all the translations without integration.

Fetching updated translations from Weblate

To fetch updated strings from Weblate, you can simply fetch the underlying Git repository (either from filesystem, or it can be made available through Git exporter). Prior to this, you might want to commit any pending changes (see Lazy commits). You can do so in the user interface (in the Repository maintenance) or from the command-line using Weblate Client.

This can be automated if you grant Weblate push access to your repository and configure Repository push URL in the Component configuration, see Pushing changes from Weblate.

Alternatively, you can use Weblate’s REST API to update translations to match their latest version.

Fetching remote changes into Weblate

To fetch the strings newly updated in your repository into Weblate, just let it pull from the upstream repository. This can be achieved in the user interface (in the Repository maintenance), or from the command-line using Weblate Client.

This can be automated by setting a webhook in your repository to trigger Weblate whenever there is a new commit, see Updating repositories for more details.

If you’re not using a VCS integration, you can use UI or Weblate’s REST API to update translations to match your code base.

Adding new strings

In case your translation files are stored in a VCS together with the code, you most likely have an existing workflow for developers to introduce new strings. Any way of adding strings will be picked up, but consider using Quality gateway for the source strings to avoid introducing errors.

When the translation files are separate from the code, there are following ways to introduce new strings into Weblate.

Manually, using Add new translation string from Tools menu in the source language.
Programatically, using API POST /api/translations/(string:project)/(string:component)/(string:language)/units/.
By uploading source file as Replace existing translation file (this overwrites existing strings, so please make sure the file includes both old and new strings) or Add new strings, see Import methods.

Note

Availability of adding strings in Weblate depends on Manage strings.

Updating target language files

For monolingual files (see Supported file formats) Weblate might add new translation strings not present in the Monolingual base language file, and not in actual translations. It does not however perform any automatic cleanup of stale strings as that might have unexpected outcomes. If you want to do this, please install Cleanup translation files addon which will handle the cleanup according to your requirements.

Weblate also will not try to update bilingual files in any way, so if you need po files being updated from pot, you need to do it yourself using Update source strings Import methods or using Update PO files to match POT (msgmerge) addon.

Managing version control repository

Weblate stores all translation the version control repository. It can be either connected to upstream one, or it can be only internal. The Repository maintenance lets you manipulate with the repository.

Hint

With Continuous localization the repository is automatically pushed whenever there are changes and there is usually no need to manually manipulate with it.

Following operations are available:

Commit

Commits any pending changes present in Weblate database and not in the repository, see Lazy commits.

Push

Pushes changes to the upstream repository, if configured by Repository push URL.

Update, Pull, Rebase

Updates Weblate repository with upstream changes. It uses Merge style when choosing Update or you can choose different one from the dropdown menu.

Lock

Locking prevents translators from doing changes

Reset from Maintenance

Resets any changes done in Weblate to match upstream repository. This will discard all translations done in Weblate and not present in the upstream repository.

Cleanup from Maintenance

Removes untracked files from the repository. These could be result of misbehaving add-ons or bugs.

Force synchronization from Maintenance

Forces writing all strings to the translation files. Use this when repository files became out of sync with Weblate for some reason.

Translating software using GNU gettext

GNU gettext is one of the most widely used tool for internationalization of free software. It provides a simple yet flexible way to localize the software. It has great support for plurals, it can add further context to the translated string and there are quite a lot of tools built around it. Of course it has great support in Weblate (see GNU gettext file format description).

Note

If you are about to use it in proprietary software, please consult licensing first, it might not be suitable for you.

GNU gettext can be used from a variety of languages (C, Python, PHP, Ruby, JavaScript and many more) and usually the UI frameworks already come with some support for it. The standard usage is through the gettext() function call, which is often aliased to _() to make the code simpler and easier to read.

Additionally it provides pgettext() call to provide additional context to translators and ngettext() which can handle plural types as defined for target language.

As a widely spread tool, it has many wrappers which make its usage really simple, instead of manual invoking of gettext described below, you might want to try one of them, for example intltool.

Workflow overview

The GNU gettext uses several files to manage the localization:

PACKAGE.pot contains strings extracted from your source code, typically using xgettext or some high level wrappers such as intltool.
LANGUAGE.po contains strings with a translation to single language. It has to be updated by msgmerge once the PACKAGE.pot is updated. You can create new language files using msginit or within Weblate.
LANGUAGE.mo contains binary representation of LANGUAGE.po and is used at application runtime. Typically it is not kept under version control, but generated at compilation time using msgfmt. In case you want to have it in the version control, you can generate it in Weblate using Generate MO files addon.

Overall the GNU gettext workflow looks like this:

Overview of GNU gettext

Sample program

The simple program in C using gettext might look like following:

#include <libintl.h>
#include <locale.h>
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    int count = 1;
    setlocale(LC_ALL, "");
    bindtextdomain("hello", "/usr/share/locale");
    textdomain("hello");
    printf(
        ngettext(
            "Orangutan has %d banana.\n",
            "Orangutan has %d bananas.\n",
            count
        ),
        count
    );
    printf("%s\n", gettext("Thank you for using Weblate."));
    exit(0);
}

Extracting translatable strings

Once you have code using the gettext calls, you can use xgettext to extract messages from it and store them into a .pot:

$ xgettext main.c -o po/hello.pot

Note

There are alternative programs to extract strings from the code, for example pybabel.

This creates a template file, which you can use for starting new translations (using msginit) or updating existing ones after code change (you would use msgmerge for that). The resulting file is simply a structured text file:

# SOME DESCRIPTIVE TITLE.
# Copyright (C) YEAR THE PACKAGE'S COPYRIGHT HOLDER
# This file is distributed under the same license as the PACKAGE package.
# FIRST AUTHOR <EMAIL@ADDRESS>, YEAR.
#
#, fuzzy
msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"POT-Creation-Date: 2015-10-23 11:02+0200\n"
"PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Language-Team: LANGUAGE <LL@li.org>\n"
"Language: \n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=CHARSET\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=INTEGER; plural=EXPRESSION;\n"

#: main.c:14
#, c-format
msgid "Orangutan has %d banana.\n"
msgid_plural "Orangutan has %d bananas.\n"
msgstr[0] ""
msgstr[1] ""

#: main.c:20
msgid "Thank you for using Weblate."
msgstr ""

Each msgid line defines a string to translate, the special empty string in the beginning is the file header containing metadata about the translation.

Starting new translation

With the template in place, we can start our first translation:

$ msginit -i po/hello.pot -l cs --no-translator -o po/cs.po
Created cs.po.

The just created cs.po already has some information filled in. Most importantly it got the proper plural forms definition for chosen language and you can see number of plurals have changed according to that:

# Czech translations for PACKAGE package.
# Copyright (C) 2015 THE PACKAGE'S COPYRIGHT HOLDER
# This file is distributed under the same license as the PACKAGE package.
# Automatically generated, 2015.

msgid_plural "Orangutan has %d bananas.\n"
msgstr[0] ""
msgstr[1] ""
msgstr[2] ""

#: main.c:20
msgid "Thank you for using Weblate."
msgstr ""

This file is compiled into an optimized binary form, the .mo file used by the GNU gettext functions at runtime.

Updating strings

Once you add more strings or change some strings in your program, you execute again xgettext which regenerates the template file:

$ xgettext main.c -o po/hello.pot

Then you can update individual translation files to match newly created templates (this includes reordering the strings to match new template):

$ msgmerge --previous --update po/cs.po po/hello.pot

Importing to Weblate

To import such translation into Weblate, all you need to define are the following fields when creating component (see Component configuration for detailed description of the fields):

Field	Value
Source code repository	URL of the VCS repository with your project
File mask	`po/*.po`
Template for new translations	`po/hello.pot`
File format	Choose gettext PO file
New language	Choose Create new language file

And that’s it, you’re now ready to start translating your software!

You can find a gettext example with many languages in the Weblate Hello project on GitHub: <https://github.com/WeblateOrg/hello>.

Translating documentation using Sphinx

Sphinx is a tool for creating beautiful documentation. It uses simple reStructuredText syntax and can generate output in many formats. If you’re looking for an example, this documentation is also built using it. The very useful companion for using Sphinx is the Read the Docs service, which will build and publish your documentation for free.

I will not focus on writing documentation itself, if you need guidance with that, just follow instructions on the Sphinx website. Once you have documentation ready, translating it is quite easy as Sphinx comes with support for this and it is quite nicely covered in their Internationalization. It’s matter of few configuration directives and invoking of the sphinx-intl tool.

If you are using Read the Docs service, you can start building translated documentation on the Read the Docs. Their Localization of Documentation covers pretty much everything you need - creating another project, set its language and link it from main project as a translation.

Now all you need is translating the documentation content. Sphinx generates PO file for each directory or top level file, what can lead to quite a lot of files to translate (depending on gettext_compact settings). You can import the index.po into Weblate as an initial component and then configure Component discovery addon to automatically discover all others.

Component configuration
Component name	`Documentation`
File mask	`docs/locales/*/LC_MESSAGES/index.po`
Template for new translations	`docs/locales/index.pot`
File format	gettext PO file
Translation flags	`rst-text`

Component discovery configuration
Regular expression to match translation files against	`docs/locales/(?P<language>[^/.])/LC_MESSAGES/(?P<component>[^/])\.po`
Customize the component name	`Documentation: {{ component\|title }}`
Define the base file for new translations	`docs/locales/{{ component }}.pot`

Hint

Would you prefer Sphinx to generate just single PO file? Since Sphinx 3.3.0 you can achieve this using:

gettext_compact = "docs"

You can find several documentation projects being translated using this approach:

Weblate documentation (you are reading that now)
Godot engine documentation
Gallette documentation
phpMyAdmin documentation

Translating HTML and JavaScript using Weblate CDN

Starting with Weblate 4.2 it is possible to export localization to a CDN using JavaScript localization CDN addon.

Note

This feature is configured on Hosted Weblate. It requires additional configuration on your installation, see LOCALIZE_CDN_URL and LOCALIZE_CDN_PATH.

Upon installation into your component it will push committed translations (see Lazy commits) to the CDN and these can be used in your web pages to localize them.

Creating component

First, you need to create a monolingual component which will hold your strings, see Adding translation projects and components for generic instructions on that.

In case you have existing repository to start with (for example the one containing HTML files), create an empty JSON file in the repository for the source language (see Source language), for example locales/en.json. The content should be {} to indicate an empty object. Once you have that, the repository can be imported into Weblate and you can start with an addon configuration.

Hint

In case you have existing translations, you can place them into the language JSON files and those will be used in Weblate.

For those who do not want to use existing repository (or do not have one), choose Start from scratch when creating component and choose JSON file as a file format (it is okay to choose any monolingual format at this point).

Configuring Weblate CDN addon

The JavaScript localization CDN addon provides few configuration options.

Translation threshold: Translations translated above this threshold will be included in the CDN.
CSS selector: Configures which strings from the HTML documents are translatable, see String extraction for Weblate CDN and HTML localization using Weblate CDN.
Language cookie name: Name of cookie which contains user selected language. Used in the JavaScript snippet for HTML localization using Weblate CDN.
Extract strings from HTML files: List of files in the repository or URLs where Weblate will look for translatable strings and offer them for a translation, see String extraction for Weblate CDN.

String extraction for Weblate CDN

The translation strings have to be present in Weblate. You can either manage these manually, use API to create them or list files or URLs using Extract strings from HTML files and Weblate will extract them automatically. The files have to present in the repository or contain remote URLs which will be download and parsed regularly by Weblate.

The default configuration for CSS selector extracts elements with CSS class l10n, for example it would extract two strings from following snippets:

<section class="content">
    <div class="row">
        <div class="wrap">
            <h1 class="section-title min-m l10n">Maintenance in progress</h1>
            <div class="page-desc">
                <p class="l10n">We're sorry, but this site is currently down for maintenance.</p>
            </div>
        </div>
    </div>
</section>

In case you don’t want to modify existing code, you can also use * as a selector to process all elements.

Note

Right now, only text of the elements is extracted. This addon doesn’t support localization of element attributes or elements with childs.

HTML localization using Weblate CDN

To localize a HTML document, you need to load the weblate.js script:

<script src="https://weblate-cdn.com/a5ba5dc29f39498aa734528a54b50d0a/weblate.js" async></script>

Upon loading, this will automatically find all matching translatable elements (based on CSS selector configuration) and replace their text with a translation.

The user language is detected from the configured cookie and falls back to user preferred languages configured in the browser.

The Language cookie name can be useful for integration with other applications (for example choose django_language when using Django).

JavaScript localization

The individual translations are exposed as bilingual JSON files under the CDN. To fetch one you can use following code:

fetch(("https://weblate-cdn.com/a5ba5dc29f39498aa734528a54b50d0a/cs.json")
  .then(response => response.json())
  .then(data => console.log(data));

The actual localization logic needs to be implemented in this case.

Translation component alerts

Shows errors in the Weblate configuration or the translation project for any given translation component. Guidance on how to address found issues is also offered.

Currently the following is covered:

Duplicated source strings in translation files
Duplicated languages within translations
Merge, update, or push failures in the repository
Parse errors in the translation files
Billing limits (see Billing)
Repository containing too many outgoing or missing commits
Missing licenses
Errors when running add-on (see Add-ons)
Misconfigured monolingual translation.
Broken Component configuration
Broken URLs
Unused screenshots
Ambiguous language code
Unused new base in component settings
Duplicate filemask used for linked components

The alerts are updated daily, or on related change (for example when Component configuration is changed or when repository is updated).

Alerts are listed on each respective component page as Alerts. If it is missing, the component clears all current checks. Alerts can not be ignored, but will disappear once the underlying problem has been fixed.

A component with both duplicated strings and languages looks like this:

Building translators community

Community localization checklist

New in version 3.9.

The Community localization checklist which can be found in the menu of each component can give you guidance to make your localization process easy for community translators.

Managing translations

Adding new translations

New strings can be made available for translation when they appear in the base file, called Template for new translations (see Component configuration). If your file format doesn’t require such a file, as is the case with most monolingual translation flows, you can start with blank files).

New languages can be added right away when requested by a user in Weblate, or a notification will be sent to project admins for approval and manual addition. This can be done using Adding new translation in Component configuration.

Note

If you add a language file in connected remote repository, respective translation will be added to the component when Weblate updates local repository.

More info on the repository update settings can be found on the Updating repositories.

Removing existing translations

Languages, components, or the projects they are in, can be removed (deleted from Weblate and remote repository if used) from the menu Manage ↓ Removal of each project, component, or language.

Initiating the Removal action shows the list of components to be removed. You have to enter the object’s slug to confirm the removal. The slug is the project’s, language’s, or component’s pathname as it can be seen in the URL.

If you want to remove just some specific strings, there are following ways:

Manually in the source file. They will be removed from the translation project as well upon Weblate’s repository update.

New in version 4.5.

In Weblate’s UI via button Tools ↓ Remove while editing the string. This has differences between file formats, see: Manage strings

Note

If you delete a language file in connected remote repository, respective translation will be removed from the component when Weblate updates local repository.

More info on the repository update settings can be found on the Updating repositories.

String variants

Variants are useful to group several strings together so that translators can see all variants of the string at one place.

Hint

Abbreviations (shortened forms, contractions) are a good example of variants.

Automated key based variants

New in version 3.11.

You can define regular expression to group the strings based on the key of monolingual translations in the Component configuration:

In case the Key matches the expression, the matching part is removed to generate root key of the variant. Then all the strings with the same root key become part of a single variant group, also including the string with the key exactly matching the root key.

The following table lists some usage examples:

Use case	Regular expression variant	Matched translation keys
Suffix identification	`(Short\|Min)$`	`monthShort`, `monthMin`, `month`
Inline identification	`#[SML]`	`dial#S.key`, `dial#M.key`, `dial.key`

Manual variants

New in version 4.5.

You can manually link specific strings using variant:SOURCE flag. This can be useful for bilingual translations which do not have keys to group strings automatically, or to group strings which keys are not matching, but should be considered together when translating.

The additional variant for a string can also be added using the Tools while translating (when Manage strings is turned on):

Note

There the variant source string has to at most 768 characters long. This is technical limitation due to compatibility with MySQL database.

Variants while translating

The variant is later grouped when translating:

String labels

Split component translation strings into categories by text and colour in the project configuration.

Hint

Labels can be assigned to units in Additional info on source strings by bulk editing, or using the Bulk edit addon.

Reviewing strings

Activity reports

Activity reports check changes of translations, for projects, components or individual users.

The activity reports for a project or component is accessible from its dashboard, on the Info tab.

More reports are accessible on the Insights tab, selecting Translation reports.

The activity of the currently signed in user can be seen by clicking on Profile from the user menu on the top right.

Source strings checks

There are many Quality checks, some of them focus on improving the quality of source strings. Many failing checks suggest a hint to make source strings easier to translate. All types of failing source checks are displayed on the Source tab of every component.

Translation string checks

Erroneous failing translation string checks indicate the problem is with the source string. Translators sometimes fix mistakes in the translation instead of reporting it - a typical example is a missing full stop at the end of a sentence.

Reviewing all failing checks can provide valuable feedback to improve its source strings. To make source strings review easier, Weblate automatically creates a translation for the source language and shows you source level checks there:

One of the most interesting checks here is the Multiple failing checks - it is triggered whenever there is failure on multiple translations of a given string. Usually this is something to look for, as this is a string which translators have problems translating properly.

The detailed listing is a per language overview:

Receiving source string feedback

Translators can comment on both translation and source strings. Each Component configuration can be configured to receive such comments to an e-mail address (see Source string bug reporting address), and using the developers mailing list is usually the best approach. This way you can keep an eye on when problems arise in translation, take care of them, and fix them quickly.

Comments

Promoting the translation

Weblate provides you widgets to share on your website or other sources to promote the translation project. It also has a nice welcome page for new contributors to give them basic information about the translation. Additionally you can share information about translation using Facebook or Twitter. All these possibilities can be found on the Share tab:

All these badges are provided with the link to simple page which explains users how to translate using Weblate:

Translation progress reporting

Reporting features give insight into how a translation progresses over a given period. A summary of contributions to any given component over time is provided. The reporting tool is found in the Insights menu of any translation component, project or on the dashboard:

Several reporting tools are available on this page and all can produce output in HTML, reStructuredText or JSON. The first two formats are suitable for embedding statistics into existing documentation, while JSON is useful for further processing of the data.

Translator credits

Generates a document usable for crediting translators - sorted by language and lists all contributors to a given language:

* Czech

    * John Doe <john@example.com> (5)
    * Jane Doe <jane@example.com> (1)

* Dutch

    * Jane Doe <jane@example.com> (42)

Hint

The number in parenthesis indicates number of contributions in given period.

Contributor stats

Generates the number of translated words and strings by translator name:

It can be useful if you pay your translators based on amount of work, it gives you various stats on translators work.

All stats are available in three variants:

Total: Overall number of edited strings.
New: Newly translated strings which didn’t have translation before.
Approved: Count for string approvals in review workflow (see Dedicated reviewers).
Edited: Edited strings which had translation before.

The following metrics are available for each:

Count: Number of strings.
Edits: Number of edits in the string, measured in Damerau–Levenshtein distance.
Source words: Number of words in the source string.
Source characters: Number of characters in the source string.
Target words: Number of words in the translated string.
Target characters: Number of characters in the translated string.

Contributing to Weblate

There are dozens of ways to improve Weblate. You can choose the one you feel comfortable with, be it coding, graphics design, documentation, sponsorship, or an idea:

Reporting issues in Weblate
Starting contributing code to Weblate
Translating Weblate
Contribute to Weblate documentation
Weblate discussions
Funding Weblate development

Translating Weblate

Weblate is continually being translated using Weblate itself. Feel free to take your part in the effort of making Weblate available in as many human languages as possible. It brings Weblate closer to its users!

If you find a possible mistake in the source string, you can mark it with a comment in the Weblate editor. This way, it can be discussed and corrected. If you’re certain, you can also click on the link in the Source string location section and submit a PR with your correction.

Contribute to Weblate documentation

You are welcome to improve the documentation page of your choice. Do it easily by clicking the Edit on GitHub button in the top-right corner of the page.

Please respect these guidelines while writing:

Don’t remove part of the documentation if it’s valid.

Use clear and easily-understandable language. You are writing tech docs, not a poem. Not all docs readers are native speakers, be thoughtful.

Don’t be affraid to ask if you are not certain. If you have to ask about some feature while editing, don’t change its docs before you have the answer. This means: You change or ask. Don’t do both at the same time.

Verify your changes by performing described actions while following the docs.

Send PR with changes in small chunks to make it easier and quicker to review and merge.

If you want to rewrite and change the structure of a big article, do it in two steps:

Rewrite

Once the rewrite is reviewed, polished, and merged, change the structure of the paragraphs in another PR.

Hint

You can translate the docs.

Extending built-in language definitions

The language definitions are in the weblate-language-data repository.

You are welcome to add missing language definitions to languages.csv, other files are generated from that file.

Weblate discussions

If you have an idea and not sure if it’s suitable for an issue, don’t worry. You can join the community in GitHub discussions.

Funding Weblate development

Starting contributing code to Weblate

Understand the Weblate source code by going through Weblate source code, Weblate frontend and Weblate internals.

Starting with the codebase

Familiarize yourself with the Weblate codebase, by having a go at the bugs labelled good first issue.

Running Weblate locally

The most comfortable approach to get started with Weblate development is to follow Installing from sources. It will get you a virtualenv with editable Weblate sources.

Clone the Weblate source code:

git clone https://github.com/WeblateOrg/weblate.git
cd weblate

Create a virtualenv:
```
virtualenv .venv
.venv/bin/activate
```
Install Weblate (for this you need some system dependencies, see Installing from sources):
```
pip install -e .
```

Install all dependencies useful for development:
```
pip install -r requirements-dev.txt
```
Start a development server:
```
weblate runserver
```
Depending on your configuration, you might also want to start Celery workers:
```
./weblate/examples/celery start
```
To run a test (see Local testing for more details):
```
. scripts/test-database
./manage.py test
```

Installing from sources

Running Weblate locally in Docker

If you have Docker and docker-compose installed, you can spin up the development environment by simply running:

./rundev.sh

It will create a development Docker image and start it. Weblate is running on <http://127.0.0.1:8080/> and you can sign in as the user admin using admin as the password. The new installation is empty, so you might want to continue with Adding translation projects and components.

The Dockerfile and docker-compose.yml for this are located in the dev-docker directory.

The script also accepts some parameters, to execute tests, run it with the test parameter and then specify any test parameters, for example running only tests in the weblate.machine module:

./rundev.sh test --failfast weblate.machine

Note

Be careful that your Docker containers are up and running before running the tests. You can check that by running the docker ps command.

To display the logs:

./rundev.sh logs

To stop the background containers, run:

./rundev.sh stop

Running the script without arguments will re-create the Docker container and restart it.

Note

This is not a suitable setup for production, as it includes several hacks which are insecure, but they make development easier.

Coding Weblate with PyCharm

PyCharm is a known IDE for Python, here are some guidelines to help you set up your Weblate project in it.

Considering you have just cloned the GitHub repository to a folder, just open it with PyCharm. Once the IDE is open, the first step is to specify the interpreter you want to use:

You can either choose to let PyCharm create the virtualenv for you, or select an already existing one:

Don’t forget to install the dependencies once the interpreter is set: Either through the console (the console from the IDE will directly use your virtualenv by default), or through the interface when you get a warning about missing dependencies.

The second step is to set the right info to use Django natively inside PyCharm: The idea is to be able to immediately trigger the unit tests in the IDE. For that you need to specify the root path of the Django project and the path to its settings:

Be careful, the Django project root is the actual root of the repository, not the Weblate sub-directory. About the settings, you could use the weblate/settings_test.py from the repository, but you could create your own setting and set it there.

The last step is to run the server and to put breakpoints in the code to be able to debug it. This is done by creating a new Django Server configuration:

Hint

Be careful with the property called No reload: It prevents the server from being reloaded live if you modify files. This allows the existing debugger breakpoints to persist, when they normally would be discarded upon reloading the server.

Bootstrapping your devel instance

You might want to use import_demo to create demo translations and createadmin to make an admin user.

Weblate source code

Weblate is developed on GitHub. You are welcome to fork the code and open pull requests. Patches in any other form are welcome too.

See also

Check out Weblate internals to see how Weblate looks from inside.

Security by Design Principles

Any code for Weblate should be written with Security by Design Principles in mind.

Coding standard

The code should follow PEP-8 coding guidelines and should be formatted using black code formatter.

To check the code quality, you can use flake8, the recommended plugins are listed in .pre-commit-config.yaml and its configuration is placed in setup.cfg.

The easiest approach to enforce all this is to install pre-commit. Weblate repository contains configuration for it to verify the committed files are sane. After installing it (it is already included in the requirements-lint.txt) turn it on by running pre-commit install in Weblate checkout. This way all your changes will be automatically checked.

You can also trigger check manually, to check all files run:

pre-commit run --all

Debugging Weblate

Bugs can behave as application crashes or as various misbehavior. You are welcome to collect info on any such issue and submit it to the issue tracker.

Debug mode

Turning on debug mode will make the exceptions show in the web browser. This is useful to debug issues in the web interface, but not suitable for a production environment because it has performance consequences and might leak private data.

In a production environment, use ADMINS to receive e-mails containing error reports, or configure error collection using a third-party service.

Weblate logs

Weblate can produce detailed logs of what is going on in the background. In the default configuration it uses syslog and that makes the log appear either in /var/log/messages or /var/log/syslog (depending on your syslog daemon configuration).

The Celery process (see Background tasks using Celery) usually produces its own logs as well. The example system-wide setups logs to several files under /var/log/celery/.

Docker containers log to their output (as per usual in the Docker world), so you can look at the logs using docker-compose logs.

See also

Sample configuration contains LOGGING configuration.

Not processing background tasks

A lot of things are done in the background by Celery workers. If things like sending out e-mails or component removal does not work, there might a related issue.

Things to check in that case:

Check that the Celery process is running, see Background tasks using Celery
Check the Celery queue status, either in Management interface, or using celery_queues
Look in the Celery logs for errors (see Weblate logs)

Not receiving e-mails from Weblate

You can verify whether outgoing e-mail is working correctly by using the sendtestemail management command (see Invoking management commands for instructions on how to invoke it in different environments) or by using Management interface under the Tools tab.

These send e-mails directly, so this verifies that your SMTP configuration is correct (see Configuring outgoing e-mail). Most of the e-mails from Weblate are however sent in the background and there might be some issues with Celery involved as well, please see Not processing background tasks for debugging that.

Analyzing application crashes

In case the application crashes, it is useful to collect as much info about the crash as possible. This can be achieved by using third-party services which can collect such info automatically. You can find info on how to set this up in Collecting error reports.

Silent failures

Lots of tasks are offloaded to Celery for background processing. Failures are not shown in the user interface, but appear in the Celery logs. Configuring Collecting error reports helps you to notice such failures easier.

Performance issues

In case Weblate performs badly in some scenario, please collect the relevant logs showing the issue, and anything that might help figuring out where the code might be improved.

In case some requests take too long without any indication, you might want to install dogslow along with Collecting error reports and get pinpointed and detailed tracebacks in the error collection tool.

Weblate internals

Note

This chapter will give you basic overview of Weblate internals.

Weblate derives most of its code structure from, and is based on Django.

Weblate frontend

The frontend is currently built using Bootstrap, jQuery and few third party libraries.

Supported browsers

Weblate supports the latest, stable releases of all major browsers and platforms.

Alternative browsers which use the latest version of WebKit, Blink, or Gecko, whether directly or via the platform’s web view API, are not explicitly supported. However, Weblate should (in most cases) display and function correctly in these browsers as well.

Older browsers might work, but some features might be limited.

Dependency management

The yarn package manager is used to update third party libraries. The configuration lives in scripts/yarn and there is a wrapper script scripts/yarn-update to upgrade the libraries, build them and copy to correct locations in weblate/static/vendor, where all third partly frontend code is located. The Weblate specific code should be placed directly in weblate/static or feature specific subdirectories (for example weblate/static/editor).

Adding new third-party library typically consists of:

# Add a yarn package
yarn --cwd scripts/yarn add PACKAGE
# Edit the script to copy package to the static folder
edit scripts/yarn-update
# Run the update script
./scripts/yarn-update
# Add files to git
git add .

Coding style

Weblate relies on Prettier for the code formatting for both JavaScript and CSS files.

We also use ESLint to check the JavaScript code.

Localization

Should you need any user visible text in the frontend code, it should be localizable. In most cases all you need is to wrap your text inside gettext function, but there are more complex features available:

document.write(gettext('this is to be translated'));

var object_count = 1 // or 0, or 2, or 3, ...
s = ngettext('literal for the singular case',
        'literal for the plural case', object_count);

fmts = ngettext('There is %s object. Remaining: %s',
        'There are %s objects. Remaining: %s', 11);
s = interpolate(fmts, [11, 20]);
// s is 'There are 11 objects. Remaining: 20'

Icons

Weblate currently uses material design icons. In case you are looking for new symbol, check Material Design Icons or Material Design Resources.

Additionally, there is scripts/optimize-svg to reduce size of the SVG as most of the icons are embedded inside the HTML to allow styling of the paths.

Reporting issues in Weblate

Weblate issue tracker is hosted at GitHub.

Feel welcome to report any issues you have, or suggest improvement for Weblate there. There are various templates prepared to comfortably guide you through the issue report.

If what you have found is a security issue in Weblate, please consult the Security issues section below.

If you are not sure about your bug report or feature request, you can try Weblate discussions.

Security issues

In order to give the community time to respond and upgrade, you are strongly urged to report all security issues privately. HackerOne is used to handle security issues, and can be reported directly at HackerOne. Once you submit it there, community has limited but enough time to solve the incident.

Alternatively, report to security@weblate.org, which ends up on HackerOne as well.

If you don’t want to use HackerOne, for whatever reason, you can send the report by e-mail to michal@cihar.com. You can choose to encrypt it using this PGP key 3CB 1DF1 EF12 CF2A C0EE 5A32 9C27 B313 42B7 511D. You can also get the PGP key from Keybase.

Note

Weblate depends on third-party components for many things. In case you find a vulnerability affecting one of those components in general, please report it directly to the respective project.

Some of these are:

Weblate testsuite and continuous integration

Testsuites exist for most of the current code, increase coverage by adding testcases for any new functionality, and verify that it works.

Continuous integration

Current test results can be found on GitHub Actions and coverage is reported on Codecov.

There are several jobs to verify different aspects:

Unit tests
Documentation build and external links
Migration testing from all supported releases
Code linting
Setup verification (ensures that generated dist files do not miss anything and can be tested)

The configuration for the CI is in .github/workflows directory. It heavily uses helper scripts stored in ci directory. The scripts can be also executed manually, but they require several environment variables, mostly defining Django settings file to use and database connection. The example definition of that is in scripts/test-database:

# Simple way to configure test database from environment

# Database backend to use postgresql / mysql / mariadb
export CI_DATABASE=${1:-postgresql}

# Database server configuration
export CI_DB_USER=weblate
export CI_DB_PASSWORD=weblate
export CI_DB_HOST=127.0.0.1

# Django settings module to use
export DJANGO_SETTINGS_MODULE=weblate.settings_test

The simple execution can look like:

. scripts/test-database
./ci/run-migrate
./ci/run-test
./ci/run-docs

Local testing

To run a testsuite locally, use:

DJANGO_SETTINGS_MODULE=weblate.settings_test ./manage.py test

Hint

You will need a database (PostgreSQL) server to be used for tests. By default Django creates separate database to run tests with test_ prefix, so in case your settings is configured to use weblate, the tests will use test_weblate database. See Database setup for Weblate for setup instructions.

The weblate/settings_test.py is used in CI environment as well (see Continuous integration) and can be tuned using environment variables:

# Simple way to configure test database from environment

# Database backend to use postgresql / mysql / mariadb
export CI_DATABASE=${1:-postgresql}

# Database server configuration
export CI_DB_USER=weblate
export CI_DB_PASSWORD=weblate
export CI_DB_HOST=127.0.0.1

# Django settings module to use
export DJANGO_SETTINGS_MODULE=weblate.settings_test

Prior to running tests you should collect static files as some tests rely on them being present:

DJANGO_SETTINGS_MODULE=weblate.settings_test ./manage.py collectstatic

You can also specify individual tests to run:

DJANGO_SETTINGS_MODULE=weblate.settings_test ./manage.py test weblate.gitexport

Hint

The tests can also be executed inside developer docker container, see Running Weblate locally in Docker.

See also

See Testing in Django for more info on running and writing tests for Django.

Releasing Weblate

Releasing schedule

Weblate has two month release cycle for releases (x.y). These are usually followed by a bunch of bugfix releases to fix issues which slip into them (x.y.z).

The change in the major version indicates that the upgrade process can not skip this version - you always have to upgrade to x.0 before upgrading to higher x.y releases.

Upgrading Weblate

Release planning

The features for upcoming releases are collected using GitHub milestones, you can see our roadmap at <https://github.com/WeblateOrg/weblate/milestones>.

Release process

Things to check prior to release:

Check newly translated languages by ./scripts/list-translated-languages.
Set final version by ./scripts/prepare-release.
Make sure screenshots are up to date make -C docs update-screenshots.
Merge any possibly pending translations wlc push; git remote update; git merge origin/weblate

Perform the release:

Create a release ./scripts/create-release --tag (see below for requirements).

Post release manual steps:

Update Docker image.
Close GitHub milestone.
Once the Docker image is tested, add a tag and push it.
Update Helm chart to new version.
Include new version in .github/workflows/migrations.yml to cover it in migration testing.
Increase version in the website download links.
Increase version in the repository by ./scripts/set-version.

To create tags using the ./scripts/create-release script you will need following:

GnuPG with private key used to sign the release
Push access to Weblate git repositories (it pushes tags)
Configured hub tool and access to create releases on the Weblate repo
SSH access to Weblate download server (the Website downloads are copied there)

Security and privacy

Tip

At Weblate, security maintains an environment that values the privacy of our users.

Development of Weblate adheres to the Best Practices of the Linux Foundation’s Core Infrastructure Initiative.

Security issues

Tracking dependencies for vulnerabilities

Security issues in our dependencies are monitored using Dependabot. This covers the Python and JavaScript libraries, and the latest stable release has its dependencies updated to avoid vulnerabilities.

Hint

There might be vulnerabilities in third-party libraries which do not affect Weblate, so those are not addressed by releasing bugfix versions of Weblate.

Docker container security

The Docker containers are regularly scanned using Anchore and Trivy security scanners.

This allows us to detect vulnerabilities early and release improvements quickly.

You can get the results of these scans at GitHub — they are stored as artifacts on our CI in the SARIF format (Static Analysis Results Interchange Format).
