According to the 2010 download stats, the most popular libs *not* in the Haskell Platform, by category are : Libs binary (rank 5/2200) utf8-string (rank 7/2200) ghc-paths (rank 15/2200) -- needed by haddock! hslogger (rank 16/2200 -- LPGL transformers (rank 18) -- related to mtl uniplate (rank 21) -- conflict with syb? terminfo (rank 25) haskeline (rank 27) -- used internally by ghci? json (rank 28) xml (rank 29) text (rank 31) HaXml (rank 33) -- LGPL HDBC (rank 42) -- LGPL convertible (rank 43) dlist (rank 54) vector (rank 55) pureMD5 (rank 70) cereal (rank 82) Apps: cpphs (rank 26) hscolour (rank 48) pandoc (rank 51) -- GPL Things we might realistically propose to add for 2011.1 New capabilities: * Binary parsing: binary + cereal ? * JSON parsing: json * An xml lib: xml -- prob. needs polish * Unicode: text * Vectors: vector * Hashing: pureMD5 With license changes to avoid static linking problems: * Databases: HDBC * XML: HaXml Questions remain about what GUI lib to bring in, to augment the OpenGL suite. * gtk2hs * wxHaskell Both cabalized, but will hamper the ease of building from source (since they bring in big C lib deps). Personally, I'd like to see binary parsing, vectors and unicode text done. Maybe JSON. -- Don
