Lua Plug-In
This Plug-In uses Lua as scripting language and is inspired from gluas, a Gimp Plug-In by Øyvind Kolås. It is compatible as possible with gluas and provides a similar syntax for basic pixel manipulation.
The Lua Plug-In is only a minimal implementation of Lua and so only a subset of Artweaver and gluas functions are implemented.

You can check many others in the "gluas examples" gallery and on the DogLua site. Most of them can be run in the Artweaver Plug-In now with no modifications. Also, be sure to have a look at the very good "Image Processing with gluas - introduction to pixel molding" tutorial at the gluas site.
For a quick start on Lua, instead, you may refer to the Lua Tutorial section of the lua-users wiki, in addition to the official Lua home.
