sphinx-intl is a utility tool that provides several features that make it easy to translate and to apply translation to Sphinx generated document. Optional: support the Transifex service for translation with Sphinx .

This section describe to translate with Sphinx and sphinx-intl command.

1. Create your document by using Sphinx.

2. Add configurations to your conf.py:

   locale_dirs = ['locale/']   #path is example but recommended.
   gettext_compact = False     #optional.
   

   locale_dirs is required and gettext_compact is optional.

3. Extract document's translatable messages into pot files:

   $ make gettext
   

4. Setup/Update your locale_dir:

   $ sphinx-intl update -p _build/locale -l de -l ja
   

   Done. You got these directories that contain po files:

   • ./locale/de/LC_MESSAGES/
   • ./locale/ja/LC_MESSAGES/

5. Translate your po files under ./locale/<lang>/LC_MESSAGES/.

6. Build mo files and make translated document:

   $ sphinx-intl build
   $ make -e SPHINXOPTS="-D language='ja'" html
   

That's all!

• create or update po files from pot files.
• build mo files from po files.

• Python 2.6, 2.7, 3.3, 3.4, 3.5, pypy.
• external library: setuptools, six, babel, click

These features need transifex-client library.

• create .transifexrc file from environment variable, without interactive input.
• create .tx/config file without interactive input.
• update .tx/config file from locale/pot files automatically.
• build mo files from po files in the locale directory.

You need to use tx command for below features:

• tx push -s : push pot (translation catalogs) to transifex.
• tx pull -l ja : pull po (translated catalogs) from transifex.

• Your transifex account if you want to download po files from transifex or you want to translate on transifex.
• external library: transifex-client

Recommend strongly: use virtualenv for this procedure:

$ pip install sphinx-intl

If you want to use Optional Features, you need install additional library:

$ pip install sphinx-intl[transifex]

Type sphinx-intl without arguments, options to show command help.

All command-line options can be set with environment variables using the format SPHINXINTL_<UPPER_LONG_NAME> . Dashes (-) have to replaced with underscores (_).

For example, to set the languages:

export SPHINXINTL_LANGUAGE=de,ja

This is the same as passing the option to sphinx-intl directly:

sphinx-intl <command> --language=de --language=ja

Add below settings to sphinx document's conf.py if not exists:

locale_dirs = ['locale/']   #for example
gettext_compact = False     #optional

make gettext will generate pot files into _build/locale directory, however pot files should be generated in the locale/pot is convenient. You can be done by replacing _build/locale with locale/pot in your Makefile and/or make.bat that was generated by sphinx-quickstart.
