Sublime Gocomplete

This Sublime Text 3 package adds support for code completions and function signatures using gocode and gogetdoc. It cooperates with Sublime Text's autocompletion system.

Dependencies

Before you can use this, you'll need to install gocode and gogetdoc:

go get -u github.com/nsf/gocode
go get -u github.com/zmb3/gogetdoc

This package also uses golangconfig to discover paths and environment variables related to Golang. It is installed automatically for you when you install this package via Package Control.

Settings

This plugin has the following settings:

{
  // Set to false to disable gocode autocompletion.
  "show_completions": true,

  // Set to false to disable signature help when hovering with the mouse.
  "show_signatures_hover": true,

  // Set to false to disable signature help when typing a function call.
  "show_signatures_paren": true
}

Autocomplete on "."

By default, Sublime Text 3 will only autocomplete when you start typing letters. If you want to autocomplete after pressing ., you can open Sublime Text -> Preferences -> Settings - Syntax Specific (while editing a Go file), and add this:

// User/Preferences.sublime-settings or User/Go.sublime-settings
{
  // ...
  "auto_complete_triggers": [
    {"selector": "source.go", "characters": "."}
  ]
}

If you only want completion after dot, you can also add this:

// User/Preferences.sublime-settings or User/Go.sublime-settings
{
  // ...
  "auto_complete_selector": "-"
}
