Usually when I'm inspecting something, I just go :ghci % and then :i the type I want. If by some chance I don't have a library installed that is needed, I just search for a function or type on hayoo and browse the hackage docs for that library.

There are ides for haskell, but I don't know how good they are. Yi is written in haskell, but I don't know how good it is. Eclipsefp is supposedly okay. I know I've seen some vim integration (haskellmode?) but I don't know how well it works. But I have never felt the absense of these tools in this language, personally.

Greetings,

So I find myself playing around with XMonad source code. I'm a long time Vim user and I've made a tags file to help me navigate the source code. I've got decent syntax highlighting.

What I lack is insight into the libs. I'd like the editor/IDE to tell me the type of a thing, or at least the module it is defined in. Is this a sensible question for haskell? I just don't want to have to hunt for where lib functions are defined (tags take me around the xmonad sources with drama).

So what editors/IDEs to people use for haskell to help with this? Or do you all just keep everything in your massive brains? :-)

Cheers,
Jeff
