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 also fix some common errors in translated strings automatically. Use it with caution to not have it add errors.

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.

BB コード マークアップ

BBcode in translation does not match source

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.

注釈

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

連続した重複重複単語

Text contains the same word twice in a row:

バージョン 4.1 で追加.

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

ヒント

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.

スペースが連続

Translation contains 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.

ヒント

In case specific format check is not available in Weblate, you can use generic プレースホルダー.

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

翻訳済み

This string has been translated in the past

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

不一致

This string has more than one translation in this project or is not translated in some components.

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.

注釈

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 occurences tab.

You can use 自動翻訳 addon to automate translating of newly added strings which are already translated in another component.

Kashida 文字の使用

The decorative kashida letters should not be used

バージョン 3.5 で追加.

The decorative Kashida letters should not be used in translation. These are also known as Tatweel.

マークダウンの参照

Markdown link references do not match source

バージョン 3.5 で追加.

Markdown link references do not match source.

マークダウンのシンタックス

Markdown syntax does not match source

バージョン 3.5 で追加.

原文とマークダウンのシンタックスが合致していないもの

翻訳の最大長

Translation should not exceed given 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.

ヒント

This checks looks at number of chars, what might not be the best metric when using proportional fonts to render the text. The 翻訳の最大長 check does check actual rendering of the text.

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

翻訳の最大長

Translation rendered text should not exceed given size

バージョン 3.7 で追加.

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), 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

ヒント

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.

n が合っていないもの

Number of n in translation does not match source

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

コロンが一致していません

Source and translation do not both end with a 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).

省略記号が一致していません

Source and translation do not both end with an 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.

感嘆符が一致していません

Source and translation do not both end with an exclamation mark

Checks that exclamations are replicated between both source and translation. The presence of exclamation marks is also checked for various languages where they do not belong (Chinese, Japanese, Korean, Armenian, Limbu, Myanmar or Nko).

終止符が一致していません

Source and translation do not both end with a full 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).

疑問符が一致していません

Source and translation do not both end with a question mark

Checks that question marks are replicated between both source and translation. The presence of question marks is also checked for various languages where they do not belong (Armenian, Arabic, Chinese, Korean, Japanese, Ethiopic, Vai or Coptic).

セミコロンが一致していません

Source and translation do not both end with a semicolon

Checks that semicolons at the end of sentences are replicated between both source and translation. This can be useful to keep formatting of entries such as desktop files.

改行数の不一致

Number of new lines in translation does not match source

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

複数形の欠如

Some plural forms are not translated

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.

プレースホルダー

Translation is missing some placeholders:

バージョン 3.9 で追加.

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"

句読点の間隔

Missing non breakable space before double punctuation sign

バージョン 3.9 で追加.

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.

正規表現

Translation does not match regular expression:

バージョン 3.9 で追加.

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

regex:^foo|bar$

同じ複数形

Some plural forms are translated in the same way

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

文頭の改行

Source and translation do not both start with a 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.

先頭の空白

Source and translation do not both start with same number of spaces

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

文末の改行

Source and translation do not both end with a 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.

文末の空白

Source and translation do not both end with a 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.

未変更の翻訳

Source and translation are identical

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.

安全でない HTML

The translation uses unsafe HTML markup

バージョン 3.9 で追加.

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

参考

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

URL

The translation does not contain an URL

バージョン 3.5 で追加.

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 マークアップ

XML tags in translation do not match source

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.

XML 構文

The translation is not valid XML

バージョン 2.8 で追加.

The XML markup is not valid.

ゼロ幅スペース

Translation contains extra zero-width space character

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.

Source checks

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

省略

The string uses three dots (...) instead of an ellipsis character (…)

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.

長期間未翻訳

The string has not been translated for a long time

バージョン 4.1 で追加.

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

複数の整合性に問題

The translations in several languages have failing checks

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.

複数の無名変数

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

バージョン 4.1 で追加.

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.

複数形でない

The string is used as plural, but not using plural forms

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
