How can you make the latest Attoparsec match strings in a case-insensitive way?
attoparsec, haskell
Solution
Use `stringCI` from `Data.Attoparsec.ByteString.Char8`. Consider switching to `Text` if you want the comparison to be Unicode-aware (e.g. so that "ß" is treated as equal to "ss").
Problem
attoparsec 0.72 had this function but it seems to have disappeared in later versions: ``` stringTransform :: (ByteString -> ByteString) -> ByteString -> Parser ByteString ``` "Match a literal string, after applying a transformation to both it and the matching text. Useful for e.g. case insensitive string comparison." http://hackage.haskell.org/package/attoparsec-0.7.2/docs/Data-Attoparsec.html
