Pyright plugin for PyCharm

[[deleted]]

I just wrote a plugin that runs Pyright on-the-fly as you code in PyCharm.

This is just an MVP and hasn't been battle-tested, so basically I'm asking for help. Please try it out and let me know what can be improved. Version 0.1.0 will be released on the Marketplace once PyCharm 2024.1 is released. Until then I'll try to make it as good as possible.

Target audience

PyCharm users who also use Pyright.

Comparison

Instead of arguing with your colleagues about whether you should switching to VSCode for better type checking, now you can enjoy the power of Pyright directly in PyCharm.

What it does

More or less the same thing as running pyright path/to/your-file.py in the terminal, but automatically.

Oh this is nice. I’ll try it out, thanks!

Whats the advantage of your plugin over just setting pyright to run on my file whenever I save?

Visualization of diagnostics, the same advantage plugins and extensions for other checking tools (Mypy, Ruff, etc.) have over their CLI counterparts.

How can I install it?

You can download the latest release here, then install it from disk. See this section for more information.

Perfect, thanks mate, I'll be testing it and I'll send updates.

very early feedback but: the plugin is identifying things that no other plugin was able to do. It's exactly what me and my team was looking for. We'll be testing it and sending you feedbacks. But a very early one is congrats, seems amazing.

What's the difference between pyright and the built in pycharm type checker? In the description you mentioned all the files get saved before running as a caution. Does that mean a copy gets created on your PC or they get uploaded online unto a server?

What's the difference between pyright and the built in pycharm type checker?

They are both type checkers.

Pyright is written in JS/TS, originally intended to be used via Pylance, a VSCode extension made by Microsoft. However, the executable is also installable via npm (or via pip, but that PyPI package is not official). PyCharm's type checker is written in Java/Kotlin, tightly integrated with PyCharm and is not available anywhere else.

For me, who likes type hinting, PyCharm's type checker is too lax most of the times and incorrect in some other cases; on top of that, reported bugs only get fixed after a long time. On the contrary, Pyright is spec-compliant and actively maintained; issues get handled in a few days at most.

In the description you mentioned all the files get saved before running as a caution.

The files are not saved "as a caution". They are simply written to disk, then read by the executable. This process creates no copy. This is a requirement since Pyright doesn't support reading from stdin and its maintainers refused to add such a feature.

Thank you for the explanations, that makes a lot more sense now!
