Querying a module for a list of functions/types

I am new to haskell and I recently installed emacs with haskell-mode and I am wondering if it is somehow possible to query a namespace to get a list of functions/types?

For example if I do

import qualified Graphics.UI.GLFW as G

and then

G.

It would be nice to see what data is inside of G. Does something like this exist?

I do not program in haskell (but I do use emacs), a bit of googling lead to this page which has some tips for using emacs for haskell, which you may find it useful. Emacs frontend to ghc-mod might provide the feature you are looking for. Scion also looks interesting.

If you're in GHCi, you can use

> :browse Grahics.UI.GLFW

If otherwise, there's several modules out there than can perform this functionality. I don't know of any plugins specific to emacs, but in Sublime Text I use the SublimeHaskell plugin which uses ghc-mod, hdevtools, and a few other packages installable from cabal to provide that sort of functionality.
