Add-ons
=======
Add-ons provide ways to customize and automate the translation workflow.
Admins can add and manage add-ons from the :guilabel:`Operations`:guilabel:`Add-ons` menu of each respective
translation project or component. Add-ons can be also installed site-wide in :ref:`management-interface`.
.. hint::
You can also configure add-ons using :ref:`API <addons-api>`,
:setting:`DEFAULT_ADDONS`, or :wladmin:`install_addon`.

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 :ref:`weblate-cdn` for more details.
.. note::
This add-on requires additional configuration on the Weblate server.
:setting:`LOCALIZE_CDN_PATH` configures where generated files will be
written (on a filesystem), and :setting:`LOCALIZE_CDN_URL` defines where
they will be served (URL). Serving of the files is not done by Weblate and
has to be set up externally (typically using a CDN service).
This add-on is configured on :guilabel:`Hosted Weblate` and serves the files
via ``https://weblate-cdn.com/``.

:Configuration: `This add-on has no configuration.`
:Triggers: :ref:`addon-event-install`, :ref:`addon-event-repository-post-commit`, :ref:`addon-event-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).
.. seealso::
:ref:`faq-cleanup`
.. _addon-weblate.cleanup.generic:
Cleanup translation files
-------------------------
:Add-on ID: ``weblate.cleanup.generic``
:Configuration: `This add-on has no configuration.`
:Triggers: :ref:`addon-event-install`, :ref:`addon-event-repository-post-update`, :ref:`addon-event-repository-pre-commit`
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.
For formats containing additional content besides translation strings (such as
:ref:`html`, :ref:`winrc`, or :ref:`odf`) this also brings the translation file
in sync with the base file.
.. seealso::
:ref:`faq-cleanup`
.. _addon-weblate.consistency.languages:
Add missing languages
---------------------
:Add-on ID: ``weblate.consistency.languages``
:Configuration: `This add-on has no configuration.`
:Triggers: :ref:`addon-event-install`, :ref:`addon-event-daily`, :ref:`addon-event-repository-post-add`
Ensures a consistent set of languages is used for all components within a
project.
.. note::
The components shared from other projects are not considered in this.
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
:ref:`addon-weblate.autotranslate.autotranslate`.

Automatically adds or removes project components based on file changes in the
version control system.
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.
The regular expression to match translation files has to contain two named
groups to match component and language. All named groups in the regular
expression can be used as variables in the template fields.
You can use Django template markup in all filename fields, for example:
``{{ component }}``
Component filename match
``{{ component|title }}``
Component filename with upper case first letter
``{{ path }}: {{ component }}``
Custom match group from the regular expression
Once you hit :guilabel:`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 :ref:`internal-urls`. Its 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 :ref:`component-repo` field (in :guilabel:`Operations`:guilabel:`Settings`
:guilabel:`Version control system`) of each respective component.
This saves time with configuration and system resources too.
.. hint::
Ensure the new component contains the full set of translatable languages with
:ref:`addon-weblate.consistency.languages`.
.. warning::
To be discovered, a new component must contain a file that matches ``base_file_template``
**and** at least one file with a name that matches ``match`` -- i.e., the component must
contain a base language file and at least one existing translation. Otherwise, it will be
ignored.

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.
Using the variable parts makes it possible to look for strings which might not
fit into the user interface after the localization - it extends the text based
on the source string length. The variable texts are repeated by length of the
text multiplied by the multiplier. For example ``Hello world`` with variable
text ``_`` and variable multiplier of 1 becomes ``Hello world___________`` -
the text is repeated once for each character in the source string.
The strings will be generated using following pattern:
:guilabel:`Prepended static text`
:guilabel:`Prepended variable text`
:guilabel:`Source string`
:guilabel:`Appended variable text`
:guilabel:`Appended static text`
.. 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.

If a translation is removed, its PO file will be deleted from the
repository, but the MO file generated by this add-on will not. The MO file
must be removed from the upstream manually.
.. _addon-weblate.gettext.msgmerge:
Update PO files to match POT (msgmerge)
---------------------------------------
.. versionchanged:: 5.13
:guilabel:`Settings` configuration has been moved to :ref:`file_format_params`.
:Add-on ID: ``weblate.gettext.msgmerge``
:Configuration: `This add-on has no configuration.`
:Triggers: :ref:`addon-event-install`, :ref:`addon-event-repository-post-update`
Updates all PO files (as configured by :ref:`component-filemask`) to match the
POT file (as configured by :ref:`component-new_base`) using :program:`msgmerge`.
This add-on is essential when working with gettext PO files where the POT
(template) file is updated with new strings or changes to existing strings.
When the POT file is updated in the repository, this add-on automatically
merges those changes into all language PO files, ensuring that:
* New translatable strings appear in all languages
* Removed strings are marked as obsolete
* Modified strings are marked as needing review (fuzzy)
Most msgmerge command-line options can be set up through file format parameters
configuration.

:Triggers: :ref:`addon-event-install`, :ref:`addon-event-repository-post-commit`
Squash Git commits prior to pushing changes.
.. hint::
To avoid unnecessary conflicts, it is recommended to configure automatic
receiving of upstream changes by webhooks or API, see :ref:`update-vcs`.
Git commits can be squashed prior to pushing changes
in one of the following modes:
* All commits into one
* Per language
* Per file
* Per author
Original commit messages are kept, but authorship is lost unless :guilabel:`Per author` is selected, or
the commit message is customized to include it.
The original commit messages can optionally be overridden with a custom commit message.
Trailers (commit lines like ``Co-authored-by: …``) can optionally be removed
from the original commit messages and appended to the end of the squashed
commit message. This also generates proper ``Co-authored-by:`` credit for every
translator.
.. _addon-weblate.json.customize:
Customize JSON output
---------------------
.. versionchanged:: 5.12
:guilabel:`Avoid spaces after separators` option added.
.. versionremoved:: 5.13 Replaced by :ref:`file_format_params`.

:Triggers: :ref:`addon-event-repository-pre-commit`
Formats and sorts the Java properties file.
* Consolidates newlines to Unix ones.
* Uppercase formatting of Unicode escape sequences (in case they are present).
* Strips blank lines and comments.
* Sorts the strings by the keys.
* Drops duplicate strings.
.. _addon-weblate.removal.comments:
Stale comment removal
---------------------
:Add-on ID: ``weblate.removal.comments``
:Configuration: +---------+--------------+--+
| ``age`` | Days to keep | |
+---------+--------------+--+
:Triggers: :ref:`addon-event-install`, :ref:`addon-event-daily`
Set a timeframe for removal of comments.
This can be useful to remove old
comments which might have become outdated. Use with care as comments
getting old does not mean they have lost their importance.
.. _addon-weblate.removal.suggestions:
Stale suggestion removal
------------------------
:Add-on ID: ``weblate.removal.suggestions``
:Configuration: +-----------+------------------+-------------------------------------------------------------------------+

+-----------+------------------+-------------------------------------------------------------------------+
:Triggers: :ref:`addon-event-install`, :ref:`addon-event-daily`
Set a timeframe for removal of suggestions.
Can be very useful in connection with suggestion voting
(see :ref:`peer-review`) to remove suggestions which
don't receive enough positive votes in a given timeframe.
.. _addon-weblate.resx.update:
Update RESX files
-----------------
:Add-on ID: ``weblate.resx.update``
:Configuration: `This add-on has no configuration.`

:Triggers: :ref:`addon-event-event-change`
Sends notifications to external services based on selected events, following
the Standard Webhooks specification.
The request payload complies with the :ref:`schema-messaging` schema.
The OpenAPI description can also be found at ``/api/docs/``.
Sample request body:
.. code-block:: json
{
"change_id": 99,
"action": "Translation changed",
"timestamp": "2019-08-24T14:15:22Z",
"target": "Nazdar svete!",
"old": "Nazdar!",
"source": "Hello, world",
"url": "/translate/project-slug/component-slug/cs/?checksum=46add148a53cab6f",
"author": "author-username",
"user": "user-username",
"project": "project-slug",
"component": "component-slug",
"translation": "cs"
}
Sample request body with categories:
.. code-block:: json
{
"change_id": 8910,
"action": "Component renamed",
"timestamp": "2025-06-11T07:15:09Z",
"target": ["new-name"],
"old": ["component-slug"],
"url": "/projects/project-slug/parent-category/child-category/sub-category/component-slug/",
"user": "testuser",
"project": "project-slug",
"component": "component-slug",
"category": [
"sub-category",
"child-category",
"parent-category"
]
}
Sample request headers:
.. code-block:: json
{
"webhook-id": "7f1c5477f6275a69af7b83236c20cb1a",
"webhook-timestamp": "1748505623.044281",
"webhook-signature": "v1,Ceo5qEr07ixe2NLpvHk3FH9bwy/WavXrAFQ/9tdO6mc="
}
The ``webhook-signature`` is a space separated list of HMAC signatures generated using the ``secret`` string,
the request payload, the ``webhook-timestamp``, and the ``webhook-id``. This ensures the authenticity
and integrity of the webhook request.
To verify a request, you can use the ``Webhook.verify`` method from the ``standardwebhooks`` library
or an implementation of the "Standard Webhooks Specification".

Customizing list of add-ons
+++++++++++++++++++++++++++
The list of add-ons is configured by :setting:`WEBLATE_ADDONS`.
To add another add-on, simply include the absolute class name in this setting.
.. _own-addon:
Writing add-on
++++++++++++++
You can write your own add-ons too, create a subclass of
:class:`weblate.addons.base.BaseAddon` to define the add-on metadata, and
then implement a callback to do the processing.
.. seealso::
:doc:`../contributing/addons`
.. _addon-script:
Executing scripts from add-on
+++++++++++++++++++++++++++++
Add-ons can also be used to execute external scripts. This used to be
integrated in Weblate, but now you have to write some code to wrap your
script with an add-on.
.. literalinclude:: ../../weblate/addons/example_pre.py
:language: python
For installation instructions see :ref:`custom-addon-modules`.
The script is executed with the current directory set to the root of the VCS repository
for any given component.
Additionally, the following environment variables are available:
.. envvar:: WL_VCS
Version control system used.
.. envvar:: WL_REPO
Upstream repository URL.
.. envvar:: WL_PATH
Absolute path to VCS repository.
.. envvar:: WL_BRANCH
Repository branch configured in the current component.
.. envvar:: WL_FILEMASK
File mask for current component.
.. envvar:: WL_TEMPLATE
Filename of template for monolingual translations (can be empty).
.. envvar:: WL_NEW_BASE
Filename of the file used for creating new translations (can be
empty).
.. envvar:: WL_FILE_FORMAT
File format used in current component.
.. envvar:: WL_LANGUAGE
Language of currently processed translation (not available for
component-level hooks).
.. envvar:: WL_PREVIOUS_HEAD
Previous HEAD after update (only available after running the post-update hook).
.. envvar:: WL_COMPONENT_SLUG
Component slug used to construct URL.
.. envvar:: WL_PROJECT_SLUG
Project slug used to construct URL.
.. envvar:: WL_COMPONENT_NAME
Component name.
.. envvar:: WL_PROJECT_NAME
Project name.
.. envvar:: WL_COMPONENT_URL
Component URL.
.. envvar:: WL_ENGAGE_URL
Project engage URL.
.. seealso::
:ref:`component`
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:
.. code-block:: sh
#! /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.
Add-on activity logging
-----------------------
Add-on activity log keeps track of the add-on execution and can be used to
keep track of add-on activity.
The logs can be pruned after a certain time interval by configuring the :setting:`ADDON_ACTIVITY_LOG_EXPIRY`.
