peg

recursive-descent parser generators for C

This package provides peg and leg, two utilities that read a Parsing Expression Grammar (PEG) and generate a recursive-descent parser for it. Unlike lex and yacc, peg and leg support unlimited backtracking, provide ordered choice as a means for disambiguation, and can combine scanning (lexical analysis) and parsing (syntactic analysis) into a single activity.
