I'm using TG2.3.9 with Jinja2 templates, and when I run "setup.py extract_messages", it does not extract any strings from jinja files inside {% trans %} block or {{ gettext('') }} etc...

the setup.py was configure as :

message_extractors={'fortress': [
    ('**.py', 'python', None),
    ('templates/**.xhtml', 'kajiki', None),
    ('templates/**.jinja', 'jinja2', None),
    ('public/**', 'ignore', None)
]},

Does anyone has any idea?

Thanks.

This should work. Are you sure your templates have the extension
".jinja" (and not ".jinja2" or ".html") and are living in the templates
directory (as specified in setup.py)? Are you sure there is no syntax
error in the jinja template? In Jinja 2.7 errors are silently ignored by
default, so it's recommended to set silent=false or use Jinja 2.8.

Hi, Chris

Thank you for replying.

1. yes, the extension is "jinja" and they are inside templaes folder;

2. jinja2 version is 2.8

3. I can see the "extract messages from ........jinja" output when running "python setup.py extract_messages"

But it just can extract {% trans %} {% endtrans %} or {{ gettext('') }} from the template files into the pot file.

You meant *can't* extract, not *can* extract, right?

I just tried it with a newly created project, and this simple template:

<html>
{{ gettext('Hello gettext!') }}
{% trans %}Hello trans!{% endtrans %}
</html>

Both texts were copied to the i18n/*.pot file.

I have used Python 2.7, TG 2.3.9, Babel 2.3.4 and Jinja2 2.8.

Are you using any different versions? Also, does it work for you with a
newly created project and the above simple template?

Hi Chris

I have the same version in my vertualenv with python version 2.7.8 and 2.7.12,

I tried both on linux and windows, and they are the same, not text inside the tags was extracted into pot file. very strange....

Problem with virtualenv ?

It should work with virtualenv as well.
Here are the steps you should try:

Create and activate a virtual env, then:

pip install tg.devtools
gearbox quickstart -jnx example
cd example
pip install .

In example/templates/about.jinja,
under {% block contents %} add these lines:

{{ gettext('Hello gettext!') }}
{% trans %}Hello trans!{% endtrans %}

Then run:

python setup.py extract_messages

The output should now contain the line:
"extracting messages from example/templates/about.jinja"

The file example/i18n/example.pot should be created
and should contain these lines taken from about.jinja:

msgid "Hello gettext!"
msgid "Hello trans!"

Hi Chris,

Thank you for your help.

I finally find the problem after I changed silent to false:

jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'with'.

It finally works:

message_extractors={'fortress': [
    ('**.py', 'python', None),

    ('templates/**.jinja', 'jinja2', {'silent': 'false', 'extensions': 'jinja2.ext.autoescape,jinja2.ext.with_'}),

    ('public/**', 'ignore', None)
]},

Thanks.

Glad you found it. I thought that silent=false was the default in 2.8,
but in fact the default didn't change, you need to set it explicitly.

No, the default silent is True:

silent = getbool(options, 'silent', True)
