ruff-lsp VS basedpyright

Here's another example: ruff-lsp, a language server for python. It describes itself as a linter and code formatter. As far as I can tell ruff-lsp does not provide code completions or semantic highlights.

I don't know if you are aware of ruff-lsp. It was created to provide the code actions. This could make your pyright + ruff combo work just fine with code actions without pylsp.

One of the things that comes to mind here is the fact that the default Python extension for VS Code is, perhaps surprisingly to many, not open source. https://github.com/microsoft/pylance-release

While it's possible to fork VS Code, it is not possible to fork VS Code and provide a seamless onramp towards a Python editing experience that is fully open source, because users are used to the nuances of the closed-source Pylance experience in VS Code proper. You could use the minified/compiled Pylance plugin in your fork, but you'd have no way to expand its capabilities to new hooks your fork provides. Microsoft's development process would always be able to move faster than a fork, because it could coordinate VS Code internal API development with its internal Pylance team, and could become incompatible with forks at any time.

It's worth re-reading the quote from J Allard in https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguis... with this modern example in mind.

(Also worth mentioning https://github.com/detachhead/basedpyright?tab=readme-ov-fil... which is a heroic effort to derisk this, but it's an uphill battle for sure!)

In the interim, check out basedpyright [1]. It's an up-to-date fork of pyright with less arbitrary limitations or the annoyance of requiring npm.
