:lang go

This module adds Go support.

  • Code completion (gocode)
  • Documentation lookup (godoc)
  • Eldoc support (go-eldoc)
  • REPL (gore)
  • Syntax-checking (flycheck)
  • Auto-formatting on save (gofmt)
  • Code navigation & refactoring (go-guru)
  • File templates
  • Snippets

I have mixed feelings about Go. It's a decent compromise between C and higher-level languages, is pleasantly straight-forward and elegant, but lacks native support for luxuries I miss from other languages, like generics, optional arguments, and function overloading. You've got to learn to love interface{}.

Still, Go is a remarkably useful (and fast!) companion for a variety of small-to-medium backend web and CLI projects.

Dependencies

This module requires a valid GOPATH, and the following Go packages:

  • gocode (for code completion & eldoc support)
  • godoc (for documentation lookup)
  • goimports (for auto-formatting code on save and fixing imports)
  • gorename (for extra refactoring commands)
  • gore (for the REPL)
  • guru (for code navigation & refactoring commands)
export GOPATH=~/work/go
