Henrik Lissner c7254e7bdc Major optimization refactor, across the board + enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster startup; ~5-20% general boost + reduce consing, function calls & garbage collection by preferring cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and various cl-lib filter/map/reduce functions) -- where possible + prefer functions with dedicated opcodes, like assq (see byte-defop's in bytecomp.el for more) + prefer pcase & cond (faster) over cl-case + general refactor for code readability + ensure naming & style conventions are adhered to + appease byte-compiler by marking unused variables with underscore + defer minor mode activation to after-init, emacs-startup or window-setup hooks; a customization opportunity for users + ensures custom functionality won't interfere with startup.		2017-06-09 00:47:45 +02:00

: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. It's a pleasantly straight-forward language with elegant syntax, 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 & 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
