ReadP -package:cabal-install

This is a module of parser combinators, originally written by Koen Claessen. It parses all alternatives in parallel, so it never keeps hold of the beginning of the input string, a common source of space leaks with other parsers. The (+++) choice combinator is genuinely commutative; it makes no difference which branch is "shorter".

Parse JSON values using the ReadP combinators.

A read-based parser for the parser modifier.

This module defines parser combinators for precedence parsing.

Parsing the SVG path command, see http://www.w3.org/TR/SVG/paths.html#PathData :

readParen True p parses what p parses, but surrounded with parentheses. readParen False p parses what p parses, but optionally surrounded with parentheses.

Lift the standard readPrec and readListPrec functions through the type constructor.

Lift the standard readPrec function through the type constructor.

Converts a parser into a Haskell ReadS-style function. This is the main way in which you can "run" a ReadP parser: the expanded type is readP_to_S :: ReadP a -> String -> [(a,String)]
