@hackage parsec-permutation0.1.2.0

Text.Parsec.Permutation is a permutation parser for parsec intended as a generalized replacement for Text.Parsec.Perm in parsec.

Example usage:

import Text.Parsec.Permutation

fooParser :: ParsecT s u m a -> ParsecT s u m [a] fooParser = runPermParser $ (,,) <$> oncePerm (char 'A') <> manyPerm (char 'B') <> optionMaybePerm (char 'C' >> char 'D')

This parser will return ('A', "BBB", Just 'D') when parsing for example the strings "BCDABB", "CDBBAB", etc.
