An autocompletion daemon for the Go programming language

Gocode is a helper tool which is intended to be integrated with your source code editor, like vim, neovim and emacs. It provides several advanced capabilities, which currently includes:

  • Context-sensitive autocompletion

It is called daemon, because it uses client/server architecture for caching purposes. In particular, it makes autocompletions very fast. Typical autocompletion time with warm cache is 30ms, which is barely noticeable.

Also watch the demo screencast.

Gocode in vim

Gocode in emacs


  1. You should have a correctly installed Go compiler environment and your personal workspace ($GOPATH). If you have no idea what $GOPATH is, take a look here. Please make sure that your $GOPATH/bin is available in your $PATH. This is important, because most editors assume that gocode binary is available in one of the directories, specified by your $PATH environment variable. Otherwise manually copy the gocode binary from $GOPATH/bin to a location which is part of your $PATH after getting it in step 2.

    Do these steps only if you understand why you need to do them:

    export GOPATH=$HOME/goprojects

    export PATH=$PATH:$GOPATH/bin

  2. Then you need to get the appropriate version of the gocode, for 6g/8g/5g compiler you can do this:

    go get -u (-u flag for "update")

    Windows users should consider doing this instead:

    go get -u -ldflags -H=windowsgui

    That way on the Windows OS gocode will be built as a GUI application and doing so solves hanging window issues with some of the editors.

  3. Next steps are editor specific. See below.

Vim setup

Vim manual installation

In order to install vim scripts, you need to fulfill the following steps:

  1. Install official Go vim scripts from $GOROOT/misc/vim. If you did that already, proceed to the step 2.

  2. Install gocode vim scripts. Usually it's enough to do the following:

    2.1. vim/ script does the following:

    mkdir -p "$HOME/.vim/autoload"
    mkdir -p "$HOME/.vim/ftplugin/go"
    cp "${0%/*}/autoload/gocomplete.vim" "$HOME/.vim/autoload"
    cp "${0%/*}/ftplugin/go/gocomplete.vim" "$HOME/.vim/ftplugin/go"

    2.2. Alternatively, you can create symlinks using script in order to avoid running after every gocode update. script does the following:

    cd "${0%/*}"
    mkdir -p "$HOME/.vim/autoload"
    mkdir -p "$HOME/.vim/ftplugin/go"
    ln -s "$ROOTDIR/autoload/gocomplete.vim" "$HOME/.vim/autoload/"
    ln -s "$ROOTDIR/ftplugin/go/gocomplete.vim" "$HOME/.vim/ftplugin/go/"
  3. Make sure vim has filetype plugin enabled. Simply add that to your .vimrc:

    filetype plugin on

  4. Autocompletion should work now. Use <C-x><C-o> for autocompletion (omnifunc autocompletion).

Using Vundle in Vim

Add the following line to your .vimrc:

Plugin 'nsf/gocode', {'rtp': 'vim/'}

And then update your packages by running :PluginInstall.

Using vim-plug in Vim

Add the following line to your .vimrc:

Plug 'nsf/gocode', { 'rtp': 'vim', 'do': '~/.vim/plugged/gocode/vim/' }

And then update your packages by running :PlugInstall.


Alternatively take a look at the vundle/pathogen friendly repo:

Neovim setup

Neovim manual installation

Neovim users should also follow Vim manual installation, except that you should goto gocode/nvim in step 2, and remember that, the Neovim configuration file is ~/.config/nvim/init.vim.

Using Vundle in Neovim

Add the following line to your init.vim:

Plugin 'nsf/gocode', {'rtp': 'nvim/'}

And then update your packages by running :PluginInstall.

Using vim-plug in Neovim

Add the following line to your init.vim:

Plug 'nsf/gocode', { 'rtp': 'nvim', 'do': '~/.config/nvim/plugged/gocode/nvim/' }

And then update your packages by running :PlugInstall.

Emacs setup

In order to install emacs script, you need to fulfill the following steps:

  1. Install auto-complete-mode

  2. Copy emacs/go-autocomplete.el file from the gocode source distribution to a directory which is in your 'load-path' in emacs.

  3. Add these lines to your .emacs:

    (require 'go-autocomplete)
    (require 'auto-complete-config)

Also, there is an alternative plugin for emacs using company-mode. See emacs-company/README for installation instructions.

If you're a MacOSX user, you may find that script useful: It helps you with setting up the right environment variables as Go and gocode require it. By default it pulls the PATH, but don't forget to add the GOPATH as well, e.g.:

(when (memq window-system '(mac ns))
  (exec-path-from-shell-copy-env "GOPATH"))


You can change all available options using gocode set command. The config file uses json format and is usually stored somewhere in ~/.config/gocode directory. On windows it's stored in the appropriate AppData folder. It's suggested to avoid modifying config file manually, do that using the gocode set command.

gocode set lists all options and their values.

gocode set <option> shows the value of that option.

gocode set <option> <value> sets the new value for that option.

  • propose-builtins

    A boolean option. If true, gocode will add built-in types, functions and constants to an autocompletion proposals. Default: false.

  • lib-path

    A string option. Allows you to add search paths for packages. By default, gocode only searches $GOPATH/pkg/$GOOS_$GOARCH and $GOROOT/pkg/$GOOS_$GOARCH in terms of previously existed environment variables. Also you can specify multiple paths using ':' (colon) as a separator (on Windows use semicolon ';'). The paths specified by lib-path are prepended to the default ones.

  • autobuild

    A boolean option. If true, gocode will try to automatically build out-of-date packages when their source files are modified, in order to obtain the freshest autocomplete results for them. This feature is experimental. Default: false.

  • force-debug-output

    A string option. If is not empty, gocode will forcefully redirect the logging into that file. Also forces enabling of the debug mode on the server side. Default: "" (empty).

  • package-lookup-mode

    A string option. If go, use standard Go package lookup rules. If gb, use gb-specific lookup rules. See for details. Default: go.


If something went wrong, the first thing you may want to do is manually start the gocode daemon with a debug mode enabled and in a separate terminal window. It will show you all the stack traces, panics if any and additional info about autocompletion requests. Shutdown the daemon if it was already started and run a new one explicitly with a debug mode enabled:

gocode close

gocode -s -debug

Please, report bugs, feature suggestions and other rants to the github issue tracker of this project.

  • It's a good idea to use the latest git version always. I'm trying to keep it in a working state.
  • Use go install (not go build) for building a local source tree. The objects in pkg/ are needed for Gocode to work.
Something went wrong with that request. Please try again.
