libtmux VS pyright

I am moving all my open source projects to `mypy --strict`. Here's the diff of adding basic / --strict mypy types:

libvcs: https://github.com/vcs-python/libvcs/pull/362/files, https://github.com/vcs-python/libvcs/pull/390/files

libtmux: https://github.com/tmux-python/libtmux/pull/382/files, https://github.com/tmux-python/libtmux/pull/383/files

unihan-etl: https://github.com/cihai/unihan-etl/pull/255/files, https://github.com/cihai/unihan-etl/pull/257/files

As for return on investment - not sure yet. What I like about it is:

- completions (through annotating)

- typings can be used downstream (since the above are all now typed python libraries)

- maintainability and bug finding. Easy to wire into CI and run locally.

There's a thread on mypy, "--strict is too strict to be useful", https://github.com/python/mypy/issues/7767. I'm not sure if I walked away with that impression. If I have a function that could potentially return `None` (`Optional[str]` or `str | None`) - it makes sense for the user to handle such a case. They could:

    assert response is not None

libtmux – Python API / wrapper for tmux

libtmux v0.12.0, GitHub, Release notes, Docs

Script-out the creation of new windows from the current window… so with the desired panes create a new window with the desired layout using the panes from the current/old window (then another script to rebuild the previous window). https://github.com/tmux-python/libtmux could make this scripting easier; I don't think tmuxinator would give you the versatile zooming effect you're looking for.

Pyright is a fast type checker meant for large Python source bases. It can run in a “watch” mode and performs fast incremental updates when files are modified.

However, I made it faster for my use-case by changing some settings. Neovim allows to have these settings in the setup function for LSP. I was trying to figure out how do I change these settings with doom emacs. Pyright docs suggest to have these settings in pyrightconfig.json.

Not exactly what you are looking for but maybe useful to others.

You can use pyright instead[0]. It is the FOSS version of pyright, but having some features missing.

Unfortunately, pyright explicitly stated that they are not interested in inlay hints or other language server features, that those will only be added to pylance. That's why I added it myself instead of submitting a pull request to pyright. See https://github.com/microsoft/pyright/issues/4325

I don't use astro, but you can configure pyright by using a pyrightconfig.json or directly in the LSP configuration.

I prefer jedi over pyright as pyright has crippled documentation support outside of VSCode. I also found jedi is make correct suggestions based on inferred type in some situations where pyright would need type annotation to provide completions, pyright is significantly faster though. Jedi with mypy and flake8 is comparable to pyright I think, but unfortunately mypy wasn't working over tramp. Also isort wasn't working over tramp, but jedi, black, importmagic and flake8 all worked.
