I am currently working on language localization of Khan Academy, I have downloaded the source 8051 from Google Code . After survey information and viewing code online, the project is made using jinja2 as the templating language. I can use babel to accomplish my work.
With the following work, I can finally enable {%trans%} and {%endtrans%} tag parse-able by the template engine with following modification:
in webapp2_extra/jinja2.py:
from django.utils import translation
env.install_gettext_translations(translation)
in config_jinja2.py
-- put following line
"extensions": ['jinja2.ext.i18n']
However, my translated template of *.mo and *.po (from pybabel) does not correctly translate tag within value in to destined language. I am thinking the babel integration should came from webapp2_extra.i18n.py, but I do not know how to enable it.
As few posts in Google mentioned that following code might work:
from webapp2_extras import i18n
env.install_gettext_translations(i18n)
However, it fails because it does not recognize {%trans%} tag.
So does anyone have the experience working on the same problem or has any suggestion to jinja2 i18n problem?
Appreciate any suggestions.
