Gopls is the official “language server protocol” (lsp) implementation
provided by the Go team. It is intended to replace the existing third party
tools for code formatting (gofmt), automatic imports (goimports), code
navigation (godef/guru), type and function descriptions (godoc/godef),
error checking, auto completion (gocode), variable and type renaming
(rename), and more. Once gopls is stable the older tools will no longer be
supported.
Gopls is a supported backend for lsp-mode. It will be used automatically by
lsp-mode if gopls is found in your ‘PATH’. You can install gopls via:
go get golang.org/x/tools/gopls@latest
To enable lsp-mode for go buffers:
