GoLang in Vim

GoLang is a common programming language. In this article we will focus on making vim support Go and use vim as an ide for it. This guide is based on a guide from octetz.com.

Build, Test, Run, Docs, Debug, Format

To enable most of the basic functions of an IDE you need to install vim-go via vim plug. For this add Plug 'fatih/vim-go' " better support for golang in your plug section in the init.vim file. Then run :PlugInstall and :GoInstallBinaries inside nvim. Finally add let g:go_def_mapping_enabled = 0 to your init.vim to make sure the mapping gd will be used by coc and its language server.

Autocompletion

Coc

To enable autocompletion for coc you need to install ccls. After that you need to add the following lines to your coc config file.

{
   "languageserver": {
        "golang": {
            "command": "gopls",
            "rootPatterns": [
                "go.mod",
                ".vim/",
                ".git/",
                ".hg/"
            ],
            "filetypes": [
                "go"
            ]
        }
   }
}
