Pylsp doesn't have diagnostics out of the box it relies on third party providers for diagnostics see: https://github.com/python-lsp/python-lsp-server#installation if you want to use one that is disabled by default (flake8 instead of pyflakes) you have to manually enable it in your config

Right, okay thanks! And wouldn't it be better to use something like pylance in that case?

[gabydd]

pylance is a proprietary language server and we would be violation of the license if we used it with helix: https://github.com/microsoft/pylance-release/blob/main/FAQ.md#can-i-load-pylance-in-code--oss

[sudokit]

Ah okay! mb

[gabydd]

for some of the type checking of pylance you can try out pyright https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers#python---pyright it does not have all the features of pylance though

Thanks!
