lparse

Parse and scan macro arguments in Lua with LuaTeX using a xparse like argument specification.

The name lparse is derived from xparse. The x has been replaced by l because this package only works with LuaTeX. l stands for Lua. Just as with xparse, it is possible to use a special syntax consisting of single letters to express the arguments of a macro. However, lparse is able to read arguments regardless of the macro systemd used - whether LaTeX or ConTeXt or even plain TeX. Of course, LuaTeX must always be used as the engine.
