0.7 released -- exposes the DBus.Wire module, which contains functions for marshaling and unmarshaling messages. Also supports detecting invalid UTF-8 when parsing (previously, it'd just error out). No other significant changes. https://dl.dropbox.com/u/1947532/dbus-core_0.7/index.html https://dl.dropbox.com/u/1947532/dbus-core_0.7.pdf It's difficult to know in advance how many bytes will be needed from the socket, so unmarshalMessage is written to pull them from a monad. If you're using it within pure code, you'll want to use Data.Binary.Get (or similar) to implement your parser: ------------------------------------------------------------------------------------- import qualified Data.Binary.Get as G import qualified Data.ByteString.Lazy as BL bytes = BL.pack [1, 2, 3, 4, 5...] getBytes = G.getLazyByteString . fromIntegral received = G.runGet (unmarshalMessage getBytes) bytes -------------------------------------------------------------------------------------
