How enable i18n support for a Sphinx theme custom?

[Leonardo Caballero]

Hi guys

How enable i18n support for a Sphinx theme custom, for example
sphinx_rtd_theme package?

https://github.com/macagua/sphinx_rtd_theme

This package is "basic" theme based built-in inside Sphinx package.

If I understand:
- Babel package is used for managment gettext format files.
- Jinja2 package is used for the HTML templates and with his i18n extension
called "jinja2.ext.i18n" is needed for load the locales files created by
Babel package.

Then exists any helper classes for to instances in my "sphinx_rtd_theme"
package and loading my locales files translated?.

I am checking the Sphinx source code, I found that "jinja2.ext.i18n" is
setting on some files:

https://github.com/sphinx-doc/sphinx/blob/9efaf18852fb076893e5a25aa624c0cba0316fa8/sphinx/util/template.py

https://github.com/sphinx-doc/sphinx/blob/1a0fe2b1ef4c1d4e4ee2302dd46eed8f8585b1c8/sphinx/jinja2glue.py

When the "jinja2.ext.i18n" is setting you can use the
"install_gettext_translations" for installs a translation globally for that
environment,
for example this
https://github.com/macagua/python_i18n_babel_jinja2/blob/master/jj2.py#L18

Then the "template.py" and "jinja2glue.py" modules are using the
implementation for "install_gettext_translations" but I don't what is the
correct way for load my "locale" files.

Any idea how extends the locale files loader mechanise for
"sphinx_rtd_theme" package?

In this moment, just it is loaded the locales inherit from sphinx theme
called "basic" built-in the Sphinx package, then I believe the problem is
Jinja2 engine don't load the my "locale" directory from my
"sphinx_rtd_theme" repository forked.

P.D.: I create an example simple for how using the Babel and Jinja2
packages into Python programs are available, check out the following

Hi,

I think `add_message_catalog` API will serve your purpose.
However the API is provided since sphinx-1.8 (in development).
http://www.sphinx-doc.org/en/master/extdev/appapi.html#sphinx.application.Sphinx.add_message_catalog

With using sphinx-1.8(repository master), please write the setup function
of sphinx_rtd_theme as bellow::

def setup(app):
app.add_html_theme('sphinx_rtd_theme',
path.abspath(path.dirname(__file__)))

rtd_locale_path = path.join(path.abspath(path.dirname(__file__)),
'locale')

# for sphinx-1.8 or later
app.add_message_catalog('sphinx', rtd_locale_path)

and `conf.py` of documentation must have::

extensions = [
'sphinx_rtd_theme',
]
language = 'es'
html_theme = 'sphinx_rtd_theme'
