I am trying to write an extension for Jinja2 so that I can run
arbitrary python code in my templates (I have a sandbox to run this
code safely). I know I can use something like Mako which allows
embedding python code but I prefer using Jinja2 as I like it's syntax
in general.
An example of what I intend to do in the template:
{{ x }}
{% code %}
x = x + 1
{% endcode %}
{{ x }}
If I render above template with x = 1, I expect the output to be,
1
2
I wrote an extension based on the example on the docs. I am able to
access the context by using the contextfunction decorator but it is
immutable.
Inside my callback in the extension, I would like to do something like
this
exec body in context
Can some Jinja2 guru help me out here?
