Go (golang) support for Vim, which comes with pre-defined sensible settings (like auto gofmt on save), with autocomplete, snippet support, improved syntax highlighting, go toolchain commands, and more. If needed vim-go installs all necessary binaries for providing seamless Vim integration with current commands. It's highly customizable and each individual feature can be disabled/enabled easily.



  • Improved Syntax highlighting with items such as Functions, Operators, Methods.
  • Auto completion support via gocode
  • Better gofmt on save, which keeps cursor position and doesn't break your undo history
  • Go to symbol/declaration with :GoDef
  • Look up documentation with :GoDoc inside Vim or open it in browser
  • Automatically import packages via :GoImport or plug it into autosave
  • Compile your package with :GoBuild, install it with :GoInstall or test them with :GoTest (also supports running single tests via :GoTestFunc)
  • Quickly execute your current file/files with :GoRun
  • Automatic GOPATH detection based on the directory structure (i.e. gb projects, godep vendored projects)
  • Change or display GOPATH with :GoPath
  • Create a coverage profile and display annotated source code to see which functions are covered with :GoCoverage
  • Call gometalinter with :GoMetaLinter, which invokes all possible linters (golint, vet, errcheck, deadcode, etc..) and shows the warnings/errors
  • Lint your code with :GoLint
  • Run your code through :GoVet to catch static errors
  • Advanced source analysis tools utilizing guru, such as :GoImplements, :GoCallees, and :GoReferrers
  • Precise type-safe renaming of identifiers with :GoRename
  • List all source files and dependencies
  • Unchecked error checking with :GoErrCheck
  • Integrated and improved snippets, supporting ultisnips or neosnippet
  • Share your current code to with :GoPlay
  • On-the-fly type information about the word under the cursor. Plug it into your custom vim function.
  • Go asm formatting on save
  • Tagbar support to show tags of the source code in a sidebar with gotags
  • Custom vim text objects such as a function or inner function list.
  • Jump to function or type declarations with :GoDecls or :GoDeclsDir
  • A async launcher for the go command is implemented for Neovim, fully async building and testing (beta).
  • Integrated with the Neovim terminal, launch :GoRun and other go commands in their own new terminal. (beta)
  • Alternate between implementation and test code with :GoAlternate


Master branch is supposed to be a development branch. So stuff here can break and change. Please try use always the latest release

Vim-go follows the standard runtime path structure, so I highly recommend to use a common and well known plugin manager to install vim-go. Do not use vim-go with other Go oriented vim plugins. For Pathogen just clone the repo. For other plugin managers add the appropriate lines and execute the plugin's install command.

  • Pathogen
  • git clone ~/.vim/bundle/vim-go
  • vim-plug
  • Plug 'fatih/vim-go'
  • NeoBundle
  • NeoBundle 'fatih/vim-go'
  • Vundle
  • Plugin 'fatih/vim-go'

Please be sure all necessary binaries are installed (such as gocode, godef, goimports, etc.). You can easily install them with the included :GoInstallBinaries command. If invoked, all necessary binaries will be automatically downloaded and installed to your $GOBIN environment (if not set it will use $GOPATH/bin). Note that this command requires git for fetching the individual Go packages. Additionally, use :GoUpdateBinaries to update the installed binaries.

  • Autocompletion is enabled by default via <C-x><C-o>. To get real-time completion (completion by type) install: neocomplete for Vim or deoplete and deoplete-go for NeoVim
  • To display source code tag information on a sidebar install tagbar.
  • For snippet features install: neosnippet or ultisnips.
  • Screenshot color scheme is a slightly modified molokai: fatih/molokai.
  • For a better documentation viewer checkout: go-explorer.


Many of the plugin's features are enabled by default. There are no additional settings needed. All usages and commands are listed in doc/vim-go.txt. Note that help tags needs to be populated. Check your plugin manager settings to generate the documentation (some do it automatically). After that just open the help page to see all commands:

:help vim-go

Example Mappings

vim-go has several <Plug> mappings which can be used to create custom mappings. Unless otherwise specified, none of these mappings are enabled by default. Here some examples you might find useful:

Run commands such as go run for the current file with <leader>r or go build and go test for the current package with <leader>b and <leader>t respectively. Display beautifully annotated source code to see which functions are covered with <leader>c.

au FileType go nmap <leader>r <Plug>(go-run)
au FileType go nmap <leader>b <Plug>(go-build)
au FileType go nmap <leader>t <Plug>(go-test)
au FileType go nmap <leader>c <Plug>(go-coverage)

By default the mapping gd is enabled, which opens the target identifier in current buffer. You can also open the definition/declaration, in a new vertical, horizontal, or tab, for the word under your cursor:

au FileType go nmap <Leader>ds <Plug>(go-def-split)
au FileType go nmap <Leader>dv <Plug>(go-def-vertical)
au FileType go nmap <Leader>dt <Plug>(go-def-tab)

Open the relevant Godoc for the word under the cursor with <leader>gd or open it vertically with <leader>gv

au FileType go nmap <Leader>gd <Plug>(go-doc)
au FileType go nmap <Leader>gv <Plug>(go-doc-vertical)

Or open the Godoc in browser

au FileType go nmap <Leader>gb <Plug>(go-doc-browser)

Show a list of interfaces which is implemented by the type under your cursor with <leader>s

au FileType go nmap <Leader>s <Plug>(go-implements)

Show type info for the word under your cursor with <leader>i (useful if you have disabled auto showing type info via g:go_auto_type_info)

au FileType go nmap <Leader>i <Plug>(go-info)

Rename the identifier under the cursor to a new name

au FileType go nmap <Leader>e <Plug>(go-rename)

More <Plug> mappings can be seen with :he go-mappings. Also these are just recommendations, you are free to create more advanced mappings or functions based on :he go-commands.


Below are some settings you might find useful. For the full list see :he go-settings.

By default syntax-highlighting for Functions, Methods and Structs is disabled. To change it:

let g:go_highlight_functions = 1
let g:go_highlight_methods = 1
let g:go_highlight_fields = 1
let g:go_highlight_structs = 1
let g:go_highlight_interfaces = 1
let g:go_highlight_operators = 1
let g:go_highlight_build_constraints = 1

Enable goimports to automatically insert import paths instead of gofmt:

let g:go_fmt_command = "goimports"

By default vim-go shows errors for the fmt command, to disable it:

let g:go_fmt_fail_silently = 1

Disable auto fmt on save:

let g:go_fmt_autosave = 0

Disable opening browser after posting your snippet to

let g:go_play_open_browser = 0

By default when :GoInstallBinaries is called, the binaries are installed to $GOBIN or $GOPATH/bin. To change it:

let g:go_bin_path = expand("~/.gotools")
let g:go_bin_path = "/home/fatih/.mypath"      "or give absolute path

Disable updating dependencies when installing/updating binaries:

let g:go_get_update = 0
Using with Neovim (beta)

Note: Neovim currently is not a first class citizen for vim-go. You are free to open bugs but I'm not going to look at them. Even though I'm using Neovim myself, Neovim itself is still alpha. So vim-go might not work well as good as in Vim. I'm happy to accept pull requests or very detailed bug reports.

Run :GoRun in a new tab, horizontal split or vertical split terminal

au FileType go nmap <leader>rt <Plug>(go-run-tab)
au FileType go nmap <Leader>rs <Plug>(go-run-split)
au FileType go nmap <Leader>rv <Plug>(go-run-vertical)

By default new terminals are opened in a vertical split. To change it

let g:go_term_mode = "split"

By default the testing commands run asynchronously in the background and display results with go#jobcontrol#Statusline(). To make them run in a new terminal

let g:go_term_enabled = 1
Using with Syntastic

Sometimes when using both vim-go and syntastic Vim will start lagging while saving and opening files. The following fixes this:

let g:syntastic_go_checkers = ['golint', 'govet', 'errcheck']
let g:syntastic_mode_map = { 'mode': 'active', 'passive_filetypes': ['go'] }

Another issue with vim-go and syntastic is that the location list window that contains the output of commands such as :GoBuild and :GoTest might not appear. To resolve this:

let g:go_list_type = "quickfix"

People have asked for this for a long time, now you can be a fully supporter by being a patron! This is fully optional and is just a way to support vim-go's ongoing development directly. Thanks!
