GitHub Play

RePlay a set of commits as they happened

Overview

GitHub Play is a scriptlet, which allows you to replay commits as they happened. Usage:

  1. Go to commits history
  2. Run the play.js script (e.g. in WebInspector/FireBug or as bookmarklet)
  3. Select two commits
  4. Hit Play on the right - it'll start Play mode and show you history between those two selected commits
  5. Hit Next after you've read the commit, you'll see the next one

Example

Open https://github.com/nette/nette/commits and run

javascript:$('head').append('<script src="https://raw.github.com/gist/1665386/play.js" />')

Ještě by to mohlo ukládat nějakou sušenku... :) A jako plugin do browseru ještě lepší :) Takový Chrome nativně podporuje userscripty.
