FAQ

How does `coc-go` compare to `vim-go`?

With coc-go I do not aim to recreate the features of vim-go. For now, the main goal is to provide a convenient way to install gopls and use it with coc.nvim.

If you need more than the features provided by gopls, you are probably better of with vim-go or govim.

How to use `coc-go` with wasm?

Add this to you (local) coc-settings.json (run :CocLocalConfig).

{
  "go.goplsEnv": {
    "GOOS": "js",
    "GOARCH": "wasm",
  }
}

Running `gopls` as a daemon

coc-go runs gopls as shared daemon by passing -remote=auto to gopls. To disable this behavior set go.goplsUseDaemon to false.

See Running gopls as a daemon for more information.

Action: config coc-setting.json for coc-go, nothing to do with vim-go
