For those who, like me, are not savvy as to what the term LPeg stands for here’s the first paragraph from a PDF file linked from one of the videos linked by the original poster:

“LPeg is a pattern-matching library for Lua, based on Parsing Expression Grammars. LPeg performs all tasks of a typical regex system, but it goes well beyond that. Among other tasks, we can write entire parsers with LPeg, with scanners included.”
