This is my take on a GitHub theme for TextMate.
This theme was created from scratch by copying colours from the GitHub pygments stylesheet. This way should highlight the differences between TextMate’s and pygments’ parser, but still have a “GitHubby” feel to it.
You should also check out Scott Becker’s take, as he used actual highlighted examples to create it and thus probably mirrors the GitHub highlighting more closely.
Just double-click or
open the GitHub.tmTheme file and TextMate will take care of installing it for you.
