B:Lua (pronounced Blua) is an open source project to create a full featured standalone Lua IDE (note: B:Lua is not an Eclipseplugin and has nothing to do with Eclipse except using the same Java API (SWT/JFace)).

B:Lua will also have a whole bunch of game related features, initially for World of Warcraft(that you can turn on/off).

B:Lua will have features such as:

Real-time code parsing and error checking

Code assist

Code completion

Code hovering / Variable info

Global search/replace with regular expressions

Fast code jumping for functions, methods and globals declared in other files

Platform:Cross platform            License:GNU General Public License(GPL)
