Missing type annotation for FILTERS

[Gabgobie]

When using Jinja2 with filters, Pylance is screaming at me because Environment.filters is partially unknown.

Environment.filters is copied from here:

jinja/src/jinja2/filters.py

Line 1812 in 5ef7011

FILTERS = {

FILTERS does not have a type annotation.

You already defined a TypeVar for the expected signature here:

jinja/src/jinja2/filters.py

Line 44 in 5ef7011

F = t.TypeVar("F", bound=t.Callable[..., t.Any])

Is there a specific reason to leave out the annotation? I'd be happy to submit a PR.

# Suggested code
FILTERS: dict[str, F] = {

Best,
Gab

Environment:

• Python version: 3.12
• Jinja version: 3.1.6
• I searched for other issues with the keywords type and filter
• I tested the suggested changes locally by modifying jinja in my venv

@nightcityblade did you work on this, or did you ask an LLM to "work" on this?

Just got pinged via email..

So now we have two attempts at writing a PR, neither of which used the tested way I suggested?

My offer still stands. I just didn't want to spam anyone with an unwanted PR or a misinterpretation of the library.

# Suggested code
FILTERS: dict[str, F] = {

The appropriate annotation is already defined in Line 44

jinja/src/jinja2/filters.py

Line 44 in 5ef7011

F = t.TypeVar("F", bound=t.Callable[..., t.Any])

What you suggest sounds reasonable to me (but i'm not super familiar w/ typing). I think opening a PR makes sense.
