Re: [Haskell-cafe] Re: is there any reason why Language.C.Syntax.AST.CTranslUnit doesn't derive show?

Hello Anatoly, Bear in mind that gshow behaves a bit differently from the regular show (namely regarding parenthesis and efficiency). You can also use standalone deriving [1] to derive Show for those datatypes. Cheers, Pedro [1] http://www.haskell.org/ghc/docs/latest/html/users_guide/deriving.html#stand-...

ah, i am guessing its because you can use Data.Generics.gshow to do the same thing. Seems like that library will come in handy when manipulating the AST, pretty cool stuff.

is there any reason why Language.C.Syntax.AST.CTranslUnit doesn't derive show? I would like to look at the data structure it generates. It's a lot easier to experiment it when i can write a template C file, print out the AST and then modify that data structure directly, instead of trying to grok the library.

Thanks for your great work btw, the parser is pretty sweet. Anatoly
