Text.Grampa.PEG.Packrat

Description

Packrat parser

Synopsis

Documentation

newtype Parser g s r Source #

Parser type for Parsing Expression Grammars that uses an improved packrat algorithm, with O(1) performance bounds but with worse constants and more memory consumption than the backtracking Parser. The parse function returns an input prefix parse paired with the remaining input suffix.
