So, you're using HabitRPG to gamify your life, right? You should be; what could be better than collecting XP and gold for fixing bugs and doing chores and flossing your teeth, and developing a totally kick-arse character you'd want to show off to all your friends?
Oh yeah, doing all that from the command-line. ;)
So, I present to you hrpg, a command-line tool to integrate with HabitRPG. It's still new, but it's very full featured.
