* Hideyuki Tanaka tan...@preferred.jp [2011-09-29 04:53:59+0900] Hello, all. I have released 'Peggy' a new parser generator . It is based on Parsing Expression Grammer (PEG) [1], and generates efficient packrat parsers. How does it compare to frisby? http://hackage.haskell.org/package/frisby An obvious advantage of frisby is its combinator interface. -- Roman I.
