;; starcraft.el -- track user APM (actions per minute) while using Emacs | |
;; | |
;; Copyright 2010 by Michael Steder | |
;; Author: Michael Steder (steder@gmail.com) | |
;; Created: 2010 | |
;; Version: 1.0 | |
;; Keywords: Actions per minute | |
;; | |
;; Inspired by a love of Starcraft and someones offhand comment | |
;; that their APM at work was significantly higher than their | |
;; Starcraft APM I started to wonder how I would determine if that | |
;; were actually true for myself. Being an Emacs user I felt | |
;; that the obvious way to answer this question was to develop | |
;; an Emacs mode that tracks emacs commands/actions. | |
;; | |
;; This is also an exercise in learning how to extend Emacs with | |
;; a new minor mode which may be more useful. | |
;; | |
;; Usage: | |
;; Add this file to a directory in emacs load path and add the following | |
;; to your ~/init.el or ~/.emacs file: | |
;; | |
;; (require 'starcraft) | |
;; (starcraft-mode t) | |
;; | |
;; Defining a minor mode: | |
(defgroup starcraft nil | |

;; idle hooks: | |
"Currently apm is calculated over the full duration of the emacs session. Idle time | |
is included and will cause your APM to drop. This may be consistent with the starcraft | |
meaning of APM and it may not. | |
I'm thinking that when emacs goes idle that I'll report the current APM and stop the stopwatch. | |
This way your APM doesn't drop drastically when you go to lunch and leave emacs running. The bottomline | |
is that while in starcraft it makes sense to calculate APM over the course of the entire game | |
that's because they can assume that you are actively playing the whole time the game is running | |
and is not paused. | |
Obviously the next step is a webservice that allows you to record your emacs apm and compete | |
with other emacs users... ;-) | |

I changed the way you calculate the APM in a way that is (in my opinion) closer to the way it's calculated in Starcraft 2 :
Just change "(/ starcraft-actions xtime) starcraft-actions xtime)"
by ( / ( * starcraft-actions 60 ) xtime ) starcraft-actions xtime)
This way, the displayed APM is always "per minute" ;)
