:lang go

This module adds Go support.

• Code completion (gocode)
• 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. I like its simplicity and syntax (mostly), but it lacks native support for certain luxuries I miss from other languages, like generics, optional arguments, and function overloading. You've got to learn to love interface{}.

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

Install

To get started with Go, you need the go tool:

MacOS

brew install go

Arch Linux

sudo pacman --needed --noconfirm -S go

Dependencies

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

• gocode (for code completion)
• gore (for the REPL)
• guru (for code navigation & refactoring commands)
• gorename (for extra refactoring commands)

export GOPATH=~/work/go

go get -u github.com/nsf/gocode
go get -u github.com/motemen/gore
go get -u golang.org/x/tools/cmd/guru
go get -u golang.org/x/tools/cmd/gorename
