  1. parseGenericPackageDescriptionMaybe :: ByteString -> Maybe GenericPackageDescription

    Cabal-syntax Distribution.PackageDescription.Parsec

    Maybe variant of parseGenericPackageDescription

  2. parsecMaybeQuoted :: CabalParsing m => m a -> m a

    Cabal-syntax Distribution.Parsec

    parsecMaybeQuoted p = parsecQuoted p | p.

  3. breakMaybe :: (a -> Maybe b) -> [a] -> ([a], Maybe (b, [a]))

    Cabal-syntax Distribution.Utils.Generic

    Like break, but with Maybe predicate 

    >>> breakMaybe (readMaybe :: String -> Maybe Int) ["foo", "bar", "1", "2", "quu"]
(["foo","bar"],Just (1,["2","quu"]))

    >>> breakMaybe (readMaybe :: String -> Maybe Int) ["foo", "bar"]
(["foo","bar"],Nothing)

  4. spanMaybe :: (a -> Maybe b) -> [a] -> ([b], [a])

    Cabal-syntax Distribution.Utils.Generic

    Like span but with Maybe predicate 

    >>> spanMaybe listToMaybe [[1,2],[3],[],[4,5],[6,7]]
([1,3],[[],[4,5],[6,7]])

    >>> spanMaybe (readMaybe :: String -> Maybe Int) ["1", "2", "foo"]
([1,2],["foo"])
