pylance-release VS emacs-jedi

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!)

Anyone know how can we fix this issue if we build the vscode locally

Do any of these issue tickets explain the behaviour you're seeing? https://github.com/microsoft/pylance-release/issues/4341, https://github.com/microsoft/pylance-release/issues/4071

Maybe they "are the same thing" in terms of behavior (I don't know), but "A uses B" doesn't mean that "A is B".

One important difference in this case is that while "Pylance leverages Microsoft's open-source static type checking tool, Pyright" [1], Pylance itself is not open source. In fact, the license [2] restricts you to "use [...] the software only with [...] Microsoft products and services", which means that you are not allowed to use it with a non-Microsoft open source fork of VS Code, for example.

The license terms also say that by accepting the license, you agree that "The software may collect information about you and your use of the software, and send that to Microsoft" and that "You may opt-out of many of these scenarios, but not all".

There's this one: https://github.com/microsoft/pylance-release/issues/4174 (rules don't apply properly, and ovverrides don't work even after being set, this is especially for the more generic ones like )

The example is not .NET in general, but that specific event when Microsoft reneged on open development tooling[1]. For some people, that was the moment they stopped trusting "new Microsoft" to keep their word (though for me, it was when the Python language server was replaced with a DRM-locked, LSP-noncompliant one[2] a bit before that; unlike .NET hot reload, they didn't backtrack there). I can think the company makes great open .NET tools and at the same time not trust them to close it down on a whim.

Does anyone know where the open xlang reimplementation of MIDL went[3], by the way? (Unlike 1990s MIDL, you can't reimplement this one from the language grammar in the docs, because there is no language grammar in the docs.)

I posted my question in stack-overflow here, but I thought I might get a quicker response if I post it here as well. There was a question before on just auto-complete for python, but I am also looking for something that does syntax-filling automatically as well. I thought emacs-jedi (for python) was something close, but not fully what I was looking for. Any suggestions for just python or just tcl or both (preferably) is highly appreciated.

For python I'm using it with company-jedi, which is orphaned but only has a hundred lines of code and leaves all the work to jedi-core from emacs-jedi. It also does display call signatures in the echo area or signatures and docstrings next to completion candidates with company-box or company-quickhelp.
