Leg is a Lua library which offers a complete Lua 5.1 grammar, along with some functions to use and modify it. Some examples of projects which could benefit from Leg are a syntax highlighter, a Luadoc-style document generator, and a macro preprocessor.
Leg uses LPeg
for pattern matching, and returns LPeg
patterns for user manipulation.
Leg is available under the same license
as Lua 5.1.
Leg can be downloaded from its LuaForge page
