LuaBucket is a thin layer between Lua and Bukkit API and therefore is a working alternative to Java and Python for lightweight plugin development. You can make some small plugins with help of this tool and apply them without restarting the whole server, testing them on-the-fly.
LuaBucket automatically picks up all .lua files from its configuration directory and processes them as Lua files. LuaBucket gives the scripts (snips in its terminology) a small API to subscribe to events and commands in a simple way.
Installation is quite simple: drop LuaBucket.jar into /plugins. Then run CraftBukkit. plugins/BucketOfLua folder will be created. Put some snips in there: examples are good enough.
/luareload - stops all scripts and then reads the snip directory again and loads everything it could find.
