Distribution.Client.Utils.Parsec

Flag' constructor, with additional phantom argument to constrain the resulting type

Like List for usage with a FieldGrammar, but for Flag. This enables to parse type aliases such as FilePath that do not have Parsec instances by using newtype variants such as FilePathNT. For example, if you need to parse a 'Flag FilePath', you can use alaFlag FilePathNT'.

alaNubList and alaNubList' are simply NubList' constructor, with additional phantom arguments to constrain the resulting type

>>> :t alaNubList VCatalaNubList VCat :: NubList a -> NubList' VCat (Identity a) a

>>> :t alaNubList' FSep TokenalaNubList' FSep Token  :: NubList String -> NubList' FSep Token String

>>> unpack' (alaNubList' FSep Token) <$> eitherParsec "foo bar foo"Right ["foo","bar"]

More general version of alaNubList.
