Re: [Haskell-cafe] Haskell type declaration summary

Hi Kevin, yes - I can do that, but it is tedious to issue each command, and I may not remember what all the types are called (I know that :browse will tell me what things exist in the current module with a capital letter) Also I want to be able to do this for a file different to the one currently loaded in GHCi. Something along the lines of (assuming a unix shell): $> showtypes MyBigMonsterHaskellFile.hs data X = A | B type Name = String newtype Y = Z Name .... $> (maybe with a blank line for each one..) Has no-one rustled up something like this - or do I need to look into Haskell parsing...? Cheers, Andrew

You can use ghci's browse:

$ ghci Prelude> import Data.Maybe Prelude Data.Maybe> :browse Data.Maybe ... Prelude Data.Maybe> :l MyFile.hs MyFile Data.Maybe> :browse MyFile ...

Dear Haskellers, any quick and easy way to extract all the type declarations from a Haskell source file? (for easy reference)
