Set evniroment for jinja2 engine

[TomFreudenberg]

Hey @derks

I want to change some defaults for rendering:

jinja2_template_handler = app.handler.resolve('template','jinja2')
jinja2_template_handler.env.trim_blocks = True

How ever I try to adjust my settings, even within a post_setup() hook,
it does not reflect the rendering.

While debugging before line:

https://github.com/datafolklabs/cement/blob/main/cement/ext/ext_jinja2.py#L120

the value stays still on False.

When I apply my changes at:

https://github.com/datafolklabs/cement/blob/main/cement/ext/ext_jinja2.py#L96-L98

it works directly.

So what would you suppose where and how to change the env settings?

Btw. is there a reason you haven't allow a config part for this?

Kind regards
Tom

Hey @derks

I created a derived extension for jinja2 and allow to do some config settings.

If you like a PR for your main jinja2 let me know.

Kind regards
Tom
