Minimal Python language server, based on Jedi and pygls.

Still in development but works on my machine. ✨

textDocument/hover Show documentation
textDocument/references Show references
textDocument/rename Renaming symbols and files





General-purpose servers (e.g. pyls, py-lsp) try to do too much and break stuff too often for me. Locking Neovim when I press tab, crashes of all kind, LspRestart failing. Also I like my linting and formatting done by dedicated tools such as nvim-lint and formatter.

Other Jedi-based servers (e.g. jedi-language-server) seem to focus on coc-nvim and frequently fail on Neovim's native LSP client for me. I tried to fix jedi-language-server several times when it failed me but I thought it could be fun to try pygls to redo it as small and simple as I can. And running a Node server to get Python completions? No way. That said, jedi-language-server is a good project and if you're fine with coc-nvim you should definitely check it out. Lots of the code here is stolen inspired from this project.

Why the name?

Take the string “Is this a Star Wars reference?” Language Server, compress it to ITASWRLS and expand it back to Italian Swirls. Italian dishes are made of few elements that work well together. Enough questions!
