This bundle is super simple: press CMD + CTRL + B (for build), and whatever textmate project you currently have open (and has focus) will be put through Jekyll! This bundle does not install Jekyll, just invokes it and displays the terminal output as a dialogue.
It should be visible in the GetBundles bundle, or in the textmate ruby gem, as it’s on GitHub.
This is the first Textmate bundle I’ve developed. Yay!
