emacs lsp-mode client for Microsoft's python language server

lsp-mode client leveraging microsoft’s python-language-server

Installation

1. Install dotnet-sdk
2. Clone and install python-language-server:

   git clone https://github.com/Microsoft/python-language-server.git
   cd python-language-server/src/LanguageServer/Impl
   dotnet build -c Release
       

   If you choose, compile the language server to a single executable with:

   dotnet publish -c Release -r osx-x64   # mac
       

   change the value of the -r flag depending on your architecture and operating system. See Microsoft’s Runtime ID Catalog for the right value for your system.

   Then, link the executable to somewhere on your path, e.g.

   ln -sf $(git rev-parse --show-toplevel)/output/bin/Release/osx-x64/publish/Microsoft.Python.LanguageServer ~/.local/bin/
       

   note that, on some systems (for example, Fedora), the executable comes out as Microsoft.Python.LanguageServer.LanguageServer.

3. Include lsp-python-ms in your config in your preferred manner. A minimal use-package initialization might be:

   (use-package lsp-python-ms
     :ensure nil
     :hook (python-mode . lsp)
     :config
   
     ;; for dev build of language server
     (setq lsp-python-ms-dir
           (expand-file-name "~/python-language-server/output/bin/Release/"))
     ;; for executable of language server, if it's not symlinked on your PATH
     (setq lsp-python-ms-executable
           "~/python-language-server/output/bin/Release/osx-x64/publish/Microsoft.Python.LanguageServer"))
       

For developement, you might find it useful to run cask install.
