Checks and fixups
=================
.. _custom-autofix:
Custom automatic fixups
-----------------------
You can also implement own automatic fixup in addition to standard ones and
include them in :setting:`AUTOFIX_LIST`.
The automatic fixes are powerful, but can also cause damage, be careful when
writing one.
For example following automatic fixup would replace every occurrence of string
``foo`` in translation with ``bar``:
.. literalinclude:: ../../examples/fix_foo.py
:language: python
.. _custom-checks:
Customizing checks
------------------
Fine tuning existing checks
+++++++++++++++++++++++++++
You can fine tune checks for each source string (in source strings review) or
in the :ref:`component` (:guilabel:`Quality checks flags`), here is current
list of flags accepted:
``rst-text``
Treat text as RST document, affects :ref:`check-same`.
``python-format``, ``c-format``, ``php-format``, ``python-brace-format``, ``javascript-format``
Treats all string like format strings, affects :ref:`check-python-format`,
:ref:`check-c-format`, :ref:`check-php-format`,
:ref:`check-python-brace-format`, :ref:`check-javascript-format`, :ref:`check-same`.
``ignore-end-space``
Skip the "Trailing space" quality check.
``ignore-inconsistent``
Skip the "Inconsistent" quality check.
``ignore-begin-newline``
Skip the "Starting newline" quality check.
``ignore-zero-width-space``
Skip the "Zero-width space" quality check.
``ignore-escaped-newline``
Skip the "Mismatched \n" quality check.
``ignore-same``
Skip the "Unchanged translation" quality check.
``ignore-end-question``
Skip the "Trailing question" quality check.
``ignore-end-ellipsis``
Skip the "Trailing ellipsis" quality check.
``ignore-ellipsis``
Skip the "Ellipsis" quality check.
``ignore-python-brace-format``
Skip the "Python brace format" quality check.
``ignore-end-newline``
Skip the "Trailing newline" quality check.
``ignore-c-format``
Skip the "C format" quality check.
``ignore-javascript-format``
Skip the "Javascript format" quality check.
``ignore-optional-plural``
Skip the "Optional plural" quality check.
``ignore-end-exclamation``
Skip the "Trailing exclamation" quality check.
``ignore-end-colon``
Skip the "Trailing colon" quality check.
``ignore-xml-tags``
Skip the "XML tags mismatch" quality check.
``ignore-python-format``
Skip the "Python format" quality check.
``ignore-plurals``
Skip the "Missing plurals" quality check.
``ignore-begin-space``
Skip the "Starting spaces" quality check.
``ignore-bbcode``
Skip the "Mismatched BBcode" quality check.
``ignore-multiple-failures``
Skip the "Multiple failing checks" quality check.
``ignore-php-format``
Skip the "PHP format" quality check.
``ignore-end-stop``
Skip the "Trailing stop" quality check.
.. 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 :ref:`component` settings, per source string
settings and in translation file itself (eg. in GNU Gettext).
Writing own checks
++++++++++++++++++
Weblate comes with wide range of quality checks (see :ref:`checks`), though
they might not 100% cover all you want to check. The list of performed checks
can be adjusted using :setting:`CHECK_LIST` and you can also add custom checks.
All you need to do is to subclass :class:`trans.checks.Check`, set few
attributes and implement either ``check`` or ``check_single`` methods (first
one if you want to deal with plurals in your code, the latter one does this for
you). You will find below some examples.
Checking translation text does not contain "foo"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is pretty simple check which just checks whether translation does not
contain string "foo".
.. literalinclude:: ../../examples/check_foo.py
:language: python
Checking Czech translation text plurals differ
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check using language information to verify that two plural forms in Czech
language are not same.
.. literalinclude:: ../../examples/check_czech.py
:language: python
