django-template-repl 0.3.0

django-template-repl is a readline shell for the Django template language.
It is similar to a CPython shell but it interprets template code instead of
Python. It can be invoked either as a management command or with a templatetag.

To install, add 'template_repl' to your settings.INSTALLED_APPS.

The management command gives you quick access to the shell:
python manage.py templateshell

You can pass a url to the management command to assume the context of a specific location:
python manage.py templateshell -u /admin/foo/bar/

You can also provide context directly with a command line option. Here is
an example of an interactive session:
$ python manage.py templateshell -c "{'foo': 'FOO', 'bar': True}"
>>> {% if bar %}
... {{ foo }}
... {% endif %}
FOO
>>>

The templateshell management command also has a --pdb option to allow you to load
the context into a namespace and start a PDB debugger shell. This works in conjunction
with the -u (--url) and -c (--context) commands. It also provides a "vars" list that
shows the names of the context variables:
$ python manage.py templateshell -u /admin/ --pdb
...
ipdb> vars
Out[0]:
['app_path',
'error_message',
'root_path',
'title',
'MEDIA_URL',
'LANGUAGES',
'LANGUAGE_BIDI',
'LANGUAGE_CODE',
'perms',
'messages',
'user']
ipdb> print user
AnonymousUser

In addition, you can use the repl templatetag which creates a REPL that assumes the
context of the caller template. This is basically "PDB for templates":
{% load repl %}{% repl %}

You can also start a real PDB shell using the same tag by giving it a second argument
of "pdb". This loads the contex into the PDB namespace:
{% load repl %}{% repl pdb %}
