The problem is Parsec itself is a type synonym. type Parsec s u = ParsecT s u Identity so that latter definition of GenParser leads to a partial application of Parsec. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

This is an incompatibility between parsec-2 and parsec-3. In parsec-2, 'GenParser' is declared with a 'data' declaration, whereas in parsec-3 it's a type synonym. Since type-synonym declared type-constructors cannot be partially applied this doesn't work. Currently in parsec-3 'GenParser' is declared as: > type GenParser tk st = Parsec [tk] st We should be able to change it to: > type GenParser tk = Parsec [tk] in Text.Parsec.String, unless I'm forgetting something else tricky about type synonyms. Derek, does this sound reasonable? -Antoine ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] There is something wrong with hprotoc-0.3.1 package.
Wow...I have a user. I wrote hprotoc, and I am adding support for protobuf-2.0.2 options in the next version of protocol-buffers and hprotoc. Let me see if I can help I just tested the tarball again and it "Works for me". I bet you are compiling without the necessary ghc flags. Cabal should be including those. I am using ghc-6.8.3 with Cabal-1.4.0.2 and tested with the command: cabal-install --verbose --user hprotoc-0.3.1.tar.gz Of course, I already have protocol-buffer-0.3.1 and protocol-buffers-descriptor-0.3.1 installed. The line 48 in my copy of Parser.hs says type P = GenParser Lexed Changing that to type P a = GenParser Lexed a still compiles and works for me. But I would be surprised if that fixed all your problems.
