Language Server Protocol support

Warning

LSP integration is still in development.

For more information https://github.com/lem-project/lem/issues/602 and https://github.com/lem-project/lem/issues/578

For information on each supported programming language, see the Modes menu.

Working with a language’s Language Server Protocol (LSP)

For some languages it should work without doing anything (for example Go, if you have gopls). Otherwise, a configuration step is required.

This is an example JS config for LSP. Place it in your ~/.lem/init.lisp (or ~/.config/lem/init.lisp since Lem 2.2) (or evaluate it with M-:).
