Homebrew Formula for a Go app

These are quick notes from making my own Formula and Tap.

Add go build script to your Git repo

gobuild.sh

#!/bin/bash

echo "$(git tag --sort=committerdate | grep -o 'v[0-9]*\.[0-9]*\.[0-9]*' | tail -n1)"

If you have only just popped it and the terminal is still open, you will still have the hash value printed by git stash pop on screen (thanks, Dolda).

git fsck --no-reflog | awk '/dangling commit/ {print $3}'
and for Windows:
