starlark integration

[hhoeflin]

Hi,

I was wondering if you ever considered making starlark (https://github.com/facebook/starlark-rust) part of jinja? With its roots in python, i thought that would potentially be a great fit to make minijinja a bit more accessible also to people who come from jinja2 and need some custom filters they have in python.

Thanks for your work

I’m not even sure what this would look like or what needs that would solve. Could you be more specific in what you have in mind?

Sorry was on vacation and couldn't reply in time.

The basic idea here would be to provide a jinja-tag that allows to define starlark functions in the template itself or to provide separate starlark modules that are read. These would then provide any functionality for which the standard filters are not enough or for light processing where some logic is needed.

An advantage compared to the current custom functions or filters would be that

• the are in python, not rust, so could be used for jinja2 as well as minijinja
• as no compilation is needed, a default CLI could be used

As starlark is safe to execute for untrusted code (outside of denial of service attack scenarios), this would help in the scenario where you would have to trust and run someone elses code.

Given jinja's roots in python, I thought starlark fills the gap where currently custom functionality needs to be provided in rust (minijinja) or a custom python environment needs to be build (jinja2) and get jinja to a place where it could be run in a CLI-only fashion in many more scenarios.

Of course I am not a power-user so I don't know if this is a really useful suggestion. I mostly wanted to make the suggestion as I was quite surprised in my search that really no-one had brought this up before.

I think stuff like this could be explored independently of minijinja/jinja2 to see if there is appetite.
