Hello, I am pleased to announce an incremental update to the ListLike package, version 3.1.0. This version adds newtype wrappers for strict and lazy ByteStrings, CharString and CharStringLazy, as well as instances of the form: instance ListLike CharString Char where ... These instances allow access to Data.ByteString.Char8 functions via the ListLike interface. Most importantly, you can now use uu-parsinglib to parse ASCII-based bytestrings via the newtype wrapper, as in: parseByteString bytestring charParser = parse charParser $ createStr (LineColPos 0 0 0) (CS bs) Thanks to S Doaitse Swierstra for making this possible via the excellent uu-parsinglib library.
