Scala parser combinator library that transforms sequences

Transfigure Parser Library

Welcome

Transfigure is a yet another parser combinator library. This library is meant was an exploration into building parsers using functional techniques and to extend the functionality with better error handling than the scala-parser-combinators library. It supports the applicative style which yields more concise code than the monadic form.
