Localization (L10N) of Trac

Trac uses  Babel for localization. Trac trunk now contains the i18n framework and L10N files.

The preference panel for language works now (since r6732).

If you're only interested in using a localized version of Trac, then refer to the simpler 0.12/TracInstall instructions. The more complete installation instructions below are aimed at developers and translators.

Note: what developers and translators are respectively supposed to do is still being discussed - the following instructions describe what I've been doing for contributing to the french translations -- cboos.

Installation

Getting the Tool Chain

  1. Install  Babel version  0.9.4
    Read the  detailed installation instructions for Babel if you want to build it from source, but you should also be able to install it with a simple easy_install or by using one of the packages in the Download page linked above.
  2. Likewise, install  Genshi, from the  Genshi:source:branches/experimental/advanced-i18n branch. No easy_install here, as you'll get some trouble running Trac trunk and other versions of Genshi together with Babel (#7834)
  3. Get a svn checkout from the Trac trunk, e.g. svn checkout http://svn.edgewall.org/repos/trac/trunk trac-0.12dev

Translation Workflow

  1. Run python setup.py extract_messages.
    This will generate the catalog template file: trac/locale/messages.pot. You won't need to edit that file manually.
  2. Run python setup.py update_catalog.
    This will regenerate the various string catalogs (trac/locale/*_*/LC_MESSAGES/messages.po), preserving the previously translated strings.
    Usually, you will be interested in just one locale, so you can provide the -l option to specify which catalog should be updated. For example:
    python setup.py update_catalog -l nl_NL.
  3. Now, open your favorite editor and add or modifiy translations for the extracted strings in the catalog for your language. See examples below.
  4. Once you're done, you should test your translations:
    • Run python setup.py update_catalog -l again, for normalizing the manual edits. For example:
      python setup.py update_catalog -l nl_NL.
      This step is also quite useful to spot the possible mistakes, like accidental change of msgid strings. Look for lines beginning with #~, they are indicative of such errors.
    • Run python setup.py compile_catalog -f.
      This will generate one compiled catalog (message.mo file) for each (or each specified) source catalog. You don't need to do anything with those files, they'll get installed automatically.
      You will most probably need to use the force option (-f) in order to compile catalogs marked "fuzzy".
      You can also use the -l option here to specify which specific locale has to be compiled.
    • Run python setup.py install for installing Trac and locale data, or you can use python setup.py develop once for all, if you want to be able to run Trac from your working copy.

Contributing

The various catalog files (messages.po) can be found in the repository under source:trunk/trac/locale. The messages.pot is the template file from which the various locale-specific files get created. If you need to create a catalog for a new locale (e.g. fr_CA), do: 

$ ./setup.py init_catalog -l fr_CA

This is a way by which translators for the same language can coordinate their work.

Terms (Definitions)

Consistent and careful translation of terms like timeline, ticket, report is very important. These terms are used everywhere and must be easy to remember and comfortable to use.

The way to make up good translations of important terms is to discuss them before using everywhere. The easiest way to accomplish it is to set up wiki pages for different languages.

Look also at the various term definition pages:

Open issues

  • i18n infrastructure for Trac plugins (#7497)
  • translation of wiki pages (#1513) and help pages (TracDev/Proposals/NewHelp)
  • translation of text within Javascript source code
  • failure to start Trac (raw NullTranslations instance has no attribute 'add' error) when no .mo file is available
