Grease Goblin is an Addon that makes writing and distributing small Scripts quick and painless. You know the Firefox Add-On Greasemonkey? Yes. It's basically just like that.

Grease Goblin uses a similar markup as Greasemonkey at the beginning of every script to define when it gets run. This markup is very simple, but cASe-sensitive. Any databases, markup and API are kept as static as possible, so that if you write a script, it will not just stop working when you update the addon.

The following example demonstrates the whole currently available markup:

-- OnLoad: true
-- OnEvent: ADDON_LOADED
-- OnEvent: SOME_OTHER_EVENT
print("Hello World!", ...);

By the way: There is a chat-command /ggb or /ggoblin to open a (resizeable) configuration window only with the Grease Goblin dialog.

To-Do

Better UI / editor (It is the WoW text editors that are buggy, so I would have to write a custom text field... Possible, but really annoying)
Document add-on API using Curse packager
Option to run a Goblin in secure environment (needs out-of-combat check for compiling)
