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.") + (home-page "https://www.piumarta.com/software/peg/") + (license (x11-style "file://LICENSE.txt")))) -- cgit v1.2.3
