Stupid Emacs trick for writing Go code

Lately, I have been writing more code outside of full-fleged IDEs and found myself tweaking Emacs into a lightweight IDE for Go. Having gofmt automagically formatting the code and refreshing it in the buffer is simply lovely. My current go-mode cusomization looks like this:

First, get the excellent go-playground package.

(package-install 'go-playround)

Then, configure Emacs

;; Automatically format your code on save
(add-hook 'before-save-hook 'gofmt-before-save)

;; Automatically display gofmt processed code in buffers
(custom-set-variables
 '(global-auto-revert-mode t)
 '(auto-revert-interval 1))

;; Verbose output when running tests via go-test-current-*
(setq go-test-args "-v")
