Разработка надстроек

Дополнения — это способ настройки рабочего процесса локализации в Weblate.

class weblate.addons.base.BaseAddon(storage)

Base class for Weblate add-ons.

classmethod can_install(*, component=None, category=None, project=None) bool

Check whether add-on is compatible with given component.

change_event(change, activity_log_id: int | None = None) dict | None

Event handler for change event.

check_change_action(change) bool

Early filtering of Change actions before triggering change_event callback.

component_update(component, activity_log_id: int | None = None) dict | None

Event handler for component update.

configure(configuration) None

Save configuration.

daily(component=None, category=None, project=None, activity_log_id: int | None = None) dict | None

Scope-aware daily entry point.

Override this for project-level logic, or override daily_component() for per-component logic.

daily_component(component, activity_log_id: int | None = None) dict | None

Per-component daily processing. Override this for component-level logic.

classmethod get_add_form(user, *, component=None, category=None, project=None, **kwargs)

Return configuration form for adding new add-on.

get_settings_form(user, **kwargs)

Return configuration form for this add-on.

manual(component=None, category=None, project=None, activity_log_id: int | None = None) dict | None

Scope-aware manual entry point.

By default this mirrors the daily handler and lets add-ons opt in explicitly by subscribing to the manual event.

manual_component(component, activity_log_id: int | None = None) dict | None

Per-component manual processing.

post_add(translation, activity_log_id: int | None = None) dict | None

Event handler after new translation is added.

post_commit(component, store_hash: bool, activity_log_id: int | None = None) dict | None

Event handler after changes are committed to the repository.

post_install(component, store_hash: bool, activity_log_id: int | None = None) dict | None

Event handler after add-on is installed.

post_push(component, activity_log_id: int | None = None) dict | None

Event handler after repository is pushed upstream.

post_remove(translation, activity_log_id: int | None = None) dict | None

Event handler after a translation is removed.

post_update(component, previous_head: str, skip_push: bool, activity_log_id: int | None = None) dict | None

Event handler after repository is updated from upstream.

Параметры:
  • previous_head (str) – HEAD of the repository prior to update, can be blank on initial clone.

  • skip_push (bool) – Whether the add-on operation should skip pushing changes upstream. Usually you can pass this to underlying methods as commit_and_push or commit_pending.

pre_commit(translation, author: str, store_hash: bool, activity_log_id: int | None = None) dict | None

Event handler before changes are committed to the repository.

pre_push(component, activity_log_id: int | None = None) dict | None

Event handler before repository is pushed upstream.

pre_update(component, activity_log_id: int | None = None) dict | None

Event handler before repository is updated from upstream.

resolve_components(*, component=None, category=None, project=None)

Resolve scope to components iterator.

save_state() None

Save add-on state information.

unit_pre_create(unit, activity_log_id: int | None = None) dict | None

Event handler before new unit is created.

update_component_state(component, updater: Callable[[dict[str, object]], None]) None

Atomically merge component-scoped add-on state into the shared JSON field.

user()

Weblate user used to track changes by this add-on.

Обработчики надстроек получают объекты ORM из модулей weblate.*.models, включая Addon, Component, Translation, Category, Project, Unit, Change и User. Формы настройки надстроек должны быть подклассом weblate.addons.forms.BaseAddonForm.

Вот пример надстройки:

Ввод конфигурации дополнения

Конфигурация надстройки хранится в JSON-поле Addon.configuration, так что модель хранит сохранённые данные как необработанный JSON. Реализации надстроек могут типизировать свою собственную конфигурацию, параметризуя BaseAddon и BaseAddonForm.

Используйте два класса TypedDict, когда хранимый JSON может отличаться от формы времени выполнения: разрешающий, как правило, total=False, сохранённую конфигурацию для устаревших или отсутствующих значений и полную конфигурацию времени выполнения, возвращаемую normalize_configuration(). Код надстройки во время выполнения должен читать self.configuration или self.get_configuration(), чтобы видеть нормализованные значения по умолчанию вместо необработанного сохранённого JSON.

Для простых надстроек, где сохраняемая и выполняемая формы идентичны, определите один TypedDict и используйте его для обоих параметров типа BaseAddon. Сохраняйте тип возврата serialize_form() формы согласованным с типом сохранённой конфигурации.
