Auto fmt / vet / build / test Go code

README.md

This is my workflow for automatically building and testing Go code. It uses steeloverseer to watch for changes to the tree and run the standard Go tools (vet, build, test) on the package as well as golint on any changed files.

Install steeloverseer with

cabal install steeloverseer && cp ~/.cabal/bin/sos ~/bin

I keep the two shell scripts in my $HOME/bin directory; they both need to be chmod +x.

#!/bin/sh
# sos: steeloverser / http://hackage.haskell.org/package/steeloverseer
# cabal install steeloverseer && cp ~/bin
#
# Inspired by Levi Cook's `glitch` (https://github.com/levicook/glitch)

# the regex makes sure that the file isn't editor crap.
