jedi language server complain python 3.10 syntax

[kasfil]

I have jedi_language_server installed trough pipx and python 3.10
but jedi complaining about new python match syntax

did i miss some configuration?

@kasfil nope, you're not missing anything! Sadly, it looks like pattern matching syntax isn't yet supported by Jedi.

• Suppport for python 3.10 alpha 6 davidhalter/jedi#1756
• Soft Keywords and How to Implement Them davidhalter/parso#138

Until that's resolved upstream, I recommend disabling jedi diagnostics if you're relying on the new pattern matching syntax.

• Relevant setting (if you're using coc-jedi): https://github.com/pappasam/coc-jedi#jedidiagnosticsenable
• Configuration object (if you're not using coc-jedi): https://github.com/pappasam/jedi-language-server#configuration

@pappasam A small update here, since this repo is probably the biggest (and only big) user of the "syntax errors" feature of Jedi.

At the moment it looks like that Python 10 syntax won't be supported for a while. This mostly won't really matter for autocompletion, goto renames, etc. I feel like we should seriously discuss just not having diagnostics in jedi-language-server, because it will likely not receive the amount of maintenance for now.

I already have a solution ready for this problem in my Rust rewrite of Jedi, but that will take a few years until it finalizes.

@davidhalter given jedi-language-server's purpose, you're the boss! If you say syntax checking is not supported by (the Python version of) Jedi, then this project should not support it either.

When I get a moment, I'll remove jedi-language-server support for diagnostics entirely and create a new release. Users can still get diagnostics errors through https://github.com/iamcco/diagnostic-languageserver

@pappasam Thanks a lot! I feel like that's the most reasonable choice for now. You could also put it behind a feature flag or something similar. It kind of makes me a bit sad, given the amount of work that went into this feature, but the amount of work that goes into this is just too big for now...

Thanks!
