An autocompletion daemon for the Go programming language

Gocode is a helper tool which is intended to be integraded with your source code editor, like vim 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. At this step, please make sure that your $GOBIN is available in your $PATH. By default $GOBIN points to $GOROOT/bin. This is important, because editors assume that gocode executable is available in one of the directories, specified by your $PATH environment variable. Usually you've done that already while installing the Go compiler suite.

    Do these steps only if you know why do you need them:

    export GOBIN=$HOME/bin

    export PATH=$PATH:$HOME/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")

  3. Next steps are editor specific. See below.

Vim setup

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:

    cd vim && ./update.bash

    update.bash script does the following:

    #!/usr/bin/env bash
    mkdir -p ~/.vim/{autoload,ftplugin}
    cp autoload/gocomplete.vim ~/.vim/autoload
    cp ftplugin/go.vim ~/.vim/ftplugin
  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).

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.


You can change all available options using gocode set command. The config file uses .ini-like format and usually stored somewhere in ~/.config/gocode directory.

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 ';').


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

gocode close

gocode -s

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


If you want to integrate gocode in your editor, please, contact me and I will tell you exactly what do you need. You can send me a message via github or simply contact me via email.


  • It's a good idea to use the latest git version always. I'm trying to keep it in a working state.
