=================================
Guidelines for Use In OpenStack
=================================
The OpenStack I18N team has a limited capacity to translate messages,
so we want to make their work as effective as possible by identifying
the most useful text for them to translate. All text messages *the
user sees* via exceptions or API calls should be marked for
translation. However, some exceptions are used internally to signal
error conditions between modules and are not intended to be presented
to the user. Those do not need to be translated.
.. seealso::
* :doc:`usage`
* :doc:`api`
Gettext Contextual Form and Plural Form
=======================================
Sometimes under different contexts, the same word should be
translated into different phrases using
:py:attr:`TranslatorFactory.contextual_form <oslo_i18n.TranslatorFactory.contextual_form>`.
And recommend the following code to use contextual form::
# The contextual translation function using the name "_C"
_C = _translators.contextual_form
...
msg = _C('context', 'string')
In some languages, sometimes the translated strings are different
with different item counts using
:py:attr:`TranslatorFactory.plural_form <oslo_i18n.TranslatorFactory.plural_form>`
And recommend the following code to use plural form::
# The plural translation function using the name "_P"
_P = _translators.plural_form
...
msg = _P('single', 'plural', count)
The contextual form and plural form are used only when needed.
By default, the translation should use the ``_()``.
.. note::
These two functions were only available in oslo.i18n >= 2.1.0.
Log Translation
===============
OpenStack supports translating some log levels using separate message
catalogs, and so has separate marker functions. These well-known names
are used by the build system jobs that extract the messages from the
source code and pass it to the translation tool.
========== ==========
Level Function
========== ==========
INFO ``_LI()``
WARNING ``_LW()``
ERROR ``_LE()``
CRITICAL ``_LC()``
========== ==========
.. note::
* Debug level log messages are not translated.
* LOG.exception creates an ERROR level log, so when a marker function is
used (see below) ``_LE()`` should be used.
Using a Marker Function
=======================
The marker functions are used to mark the translatable strings in the
code. The strings are extracted into catalogs using a tool that
looks for these specific markers, so the function argument must just
be a string.
For example: **do not do this**::
# WRONG
msg = _(variable_containing_msg)
w_msg = _LW(variable_warning_msg)
Instead, use this style::
# RIGHT
msg = _('My message.')
w_msg = _LW('My warning message')
Choosing a Marker Function
==========================
The purpose of the different marker functions is to separate the
translatable messages into different catalogs, which the translation
teams can prioritize translating. It is important to choose the right
marker function, to ensure that strings the user sees will be
translated and to help the translation team manage their work load.
Everything marked with ``_()`` will be translated. Prioritizing the
catalogs created from strings marked with the log marker functions is
up to the individual translation teams and their users, but it is
expected that they will work on critical and error messages before
warning or info.
``_()`` is preferred for any user facing message, even if it is also
going to a log file. This ensures that the translated version of the
message will be available to the user.
The log marker functions (``_LI()``, ``_LW()``, ``_LE()``, and ``_LC()``)
must only be used when the message is only sent directly to the log.
Anytime that the message will be passed outside of the current context
(for example as part of an exception) the ``_()`` marker function
must be used.
A common pattern is to define a single message object and use it more
than once, for the log call and the exception. In that case, ``_()``
must be used because the message is going to appear in an exception that
may be presented to the user.
For example, **do not do this**::
# WRONG
msg = _LE('There was an error.')
LOG.exception(msg)
raise LocalExceptionClass(msg)
Instead, use this style::
# RIGHT
msg = _('There was an error.')
LOG.exception(msg)
raise LocalExceptionClass(msg)
Except in the case above, ``_()`` should not be used for translating
log messages. This avoids having the same string in two message
catalogs, possibly translated differently by two different
translators. The log message will translate properly because when
the message is not found in the log specific catalog the ``_()``
catalog will be used.
If a common message is not being used, they should each be treated
separately with respect to choosing a marker function.
For example, **do not do this**::
# WRONG
LOG.exception(_('There was an error.'))
raise LocalExceptionClass(_('An error occured.'))
Instead, use this style::
# RIGHT
LOG.exception(_LE('There was an error.'))
raise LocalExceptionClass(_('An error occured.'))
Adding Variables to Translated Messages
=======================================
Translated messages should not be combined with other literal strings
to create partially translated messages. For example, **do not do
this**::
# WRONG
raise ValueError(_('some message') + ': variable=%s' % variable)
Instead, use this style::
# RIGHT
raise ValueError(_('some message: variable=%s') % variable)
Including the variable reference inside the translated message allows
the translator to take into account grammar rules, differences in
left-right vs. right-left rendering, and other factors to make the
translated message more useful to the end user.
Any message with more than one variable should use named interpolation
instead of positional, to allow translators to move the variables
around in the string to account for differences in grammar and writing
direction.
For example, **do not do this**::
# WRONG
raise ValueError(_('some message: v1=%s v2=%s') % (v1, v2))
Instead, use this style::
# RIGHT
raise ValueError(_('some message: v1=%(v1)s v2=%(v2)s') % {'v1': v1, 'v2': v2})
Adding Variables to Log Messages
================================
String interpolation should be delayed to be handled by the logging
code, rather than being done at the point of the logging call. For
example, **do not do this**::
# WRONG
LOG.info(_LI('some message: variable=%s') % variable)
Instead, use this style::
# RIGHT
LOG.info(_LI('some message: variable=%s'), variable)
This allows the logging package to skip creating the formatted log
message if the message is not going to be emitted because of the
current log level.
Avoid Forcing the Translation of Translatable Variables
=======================================================
Translation can also be delayed for variables that potentially contain
translatable objects such as exceptions.
Whenever possible translation should not be forced by use of :func:`str`,
:func:`unicode`, or :func:`six.text_type` on a message being used with
a format string.
For example, **do not do this**::
# WRONG
LOG.info(_LI('some message: exception=%s'), six.text_type(exc))
Instead, use this style::
# RIGHT
LOG.info(_LI('some message: exception=%s'), exc)
This allows the translation of the translatable replacement text to be
delayed until the message is translated.

How to Use oslo.i18n in Your Application or Library
=====================================================
Installing
==========
At the command line::
$ pip install oslo.i18n
.. _integration-module:
Creating an Integration Module
==============================
To use oslo.i18n in a project (e.g. myapp), you will need to create a
small integration module to hold an instance of
:class:`~oslo_i18n.TranslatorFactory` and references to
the marker functions the factory creates.
.. note::
Libraries probably do not want to expose the new integration module
as part of their public API, so rather than naming it
``myapp.i18n`` it should be called ``myapp._i18n`` to indicate that
it is a private implementation detail, and not meant to be used
outside of the library's own code.
.. code-block:: python
# myapp/_i18n.py
import oslo_i18n
DOMAIN = "myapp"
_translators = oslo_i18n.TranslatorFactory(domain=DOMAIN)
# The primary translation function using the well-known name "_"
_ = _translators.primary
# The contextual translation function using the name "_C"
# requires oslo.i18n >=2.1.0
_C = _translators.contextual_form
# The plural translation function using the name "_P"
# requires oslo.i18n >=2.1.0
_P = _translators.plural_form
# Translators for log levels.
#
# The abbreviated names are meant to reflect the usual use of a short
# name like '_'. The "L" is for "log" and the other letter comes from
# the level.
_LI = _translators.log_info
_LW = _translators.log_warning
_LE = _translators.log_error
_LC = _translators.log_critical
def get_available_languages():
return oslo_i18n.get_available_languages(DOMAIN)
Then, in the rest of your code, use the appropriate marker function
for each message:
.. code-block:: python
from myapp._i18n import _, _LW, _LE
# ...
variable = "openstack"
LOG.warning(_LW('warning message: %s'), variable)
# ...
try:
# ...
except AnException1:
# Log only
LOG.exception(_LE('exception message'))
except AnException2:
# Raise only
raise RuntimeError(_('exception message'))
else:
# Log and Raise
msg = _('Unexpected error message')
LOG.exception(msg)
raise RuntimeError(msg)
.. note::
The import of multiple modules from _i18n on a single line is
a valid exception to
`OpenStack Style Guidelines <http://docs.openstack.org/developer/hacking/#imports>`_
for import statements.
It is important to use the marker functions (e.g. _LI), rather than
the longer form of the name, because the tool that scans the source
code for translatable strings looks for the marker function names.
.. warning::
The old method of installing a version of ``_()`` in the builtins
namespace is deprecated. Modifying the global namespace affects
libraries as well as the application, so it may interfere with
proper message catalog lookups. Calls to
:func:`gettextutils.install` should be replaced with the
application or library integration module described here.
Handling hacking Objections to Imports
======================================
The `OpenStack Style Guidelines <http://docs.openstack.org/developer/hacking/#imports>`_
prefer importing modules and accessing names from those modules after
import, rather than importing the names directly. For example:
::
# WRONG
from foo import bar
bar()
# RIGHT
import foo
foo.bar()
The linting tool hacking_ will typically complain about importing
names from within modules. It is acceptable to bypass this for the
translation marker functions, because they must have specific names
and their use pattern is dictated by the message catalog extraction
tools rather than our style guidelines. To bypass the hacking check
for imports from this integration module, add an import exception to
``tox.ini``.
For example::
# tox.ini
[hacking]
import_exceptions = myapp._i18n
.. _hacking: https://pypi.python.org/pypi/hacking
.. _lazy-translation:
Lazy Translation
================
Lazy translation delays converting a message string to the translated
form as long as possible, including possibly never if the message is
not logged or delivered to the user in some other way. It also
supports logging translated messages in multiple languages, by
configuring separate log handlers.
Lazy translation is implemented by returning a special object from the
translation function, instead of a unicode string. That special
message object supports some, but not all, string manipulation
APIs. For example, concatenation with addition is not supported, but
interpolation of variables is supported. Depending on how translated
strings are used in an application, these restrictions may mean that
lazy translation cannot be used, and so it is not enabled by default.
To enable lazy translation, call :func:`enable_lazy`.
::
import oslo_i18n
oslo_i18n.enable_lazy()
Translating Messages
====================
Use :func:`~oslo_i18n.translate` to translate strings to
a specific locale. :func:`translate` handles delayed translation and
strings that have already been translated immediately. It should be
used at the point where the locale to be used is known, which is often
just prior to the message being returned or a log message being
emitted.
::
import oslo_i18n
trans_msg = oslo_i18n.translate(msg, my_locale)
If a locale is not specified the default locale is used.
Available Languages
===================
Only the languages that have translations provided are available for
translation. To determine which languages are available the
:func:`~oslo_i18n.get_available_languages` is provided. The integration
module provides a domain defined specific function.
.. code-block:: python
import myapp._i18n
languages = myapp._i18n.get_available_languages()
