Add semantic syntax higlighting similar to pylance

[geetmankar]

Hi,

This is an enhancement proposal. Just wanted to know if it will be at all possible to color imported modules, classes (when they're used in type annotations), generics, and functions like VSCode PyLance does, or if it is out of the scope of this project.

Without PyLance:

With PyLance:

I feel like this can be very helpful to distinguish between what's being imported object is a class or a generic/type alias at a glance.

Do you know if what you're referring to is Pylance's semantic highlighting feature?

That seems to be exactly what I was referring to.

Pinging this to get some more attention - this is a needed feature for me!

Red knot is still in progress. See Charlie's recent announcement.

Hi where I can see the announcement?

Red knot is still in progress. See Charlie's recent announcement.

What does that mean? I can see that #438 and #11664 (ruff repo) are closed..

I'm not sure why #438 is closed as completed when Micha said that it's planned. As for astral-sh/ruff#11664, that is only one of many things related to red knot. It's meant to be a full type checker for python, so it is, understandably, a very large undertaking. You can see related issues/PRs by searching for the "red-knot" label.

Note also that this repo is for the now less-used python server. It has been replaced by the native server that is built-in to ruff, which you should probably be using instead (see the documentation).

Thank you for taking the time to explain all that. I'll keep an eye on red knot!
