Lua editors/B:Lua

B:Lua (pronounced Blua) is an open source project to create a full featured standalone Lua IDE (note: B:Lua is not an Eclipse plugin 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:

• 1) Real-time code parsing and error checking
• 2) Code assist
• 3) Code completion
• 4) Code hovering / Variable info
• 5) Global search/replace with regular expressions
• 6) Fast code jumping for functions, methods and globals declared in other files
• 7) Much much more
