Hi,

I am pondering using \pdfmatch for some application that might eventually be migrated to LuaTeX. My scraps of half-knowledge right of the top of my head indicate that LPEG is compiled into LuaTeX,

This is 100% true.

and that LPEG contains a module that is able to parse regular expression syntax into LPEG.

A specific form of regular expression syntax, yes. http://www.inf.puc-rio.br/~roberto/lpeg/re.html But I do not know whether that matches up with libc's regex routines. Best wishes, Taco
