Go

Lem supports Go.

Start it with Alt-x go-mode.

LSP

Its LSP config is:


(define-language-spec (go-spec lem-go-mode:go-mode)
  :language-id "go"
  :root-uri-patterns '("go.mod")
  :command (lambda (port) `("gopls" "serve" "-port" ,(princ-to-string port)))
  :install-command "go install golang.org/x/tools/gopls@latest"
  :readme-url "https://github.com/golang/tools/tree/master/gopls"
  :connection-mode :tcp)

Please install gopls and refer to Lem’s LSP documentation.
