haskell - Is there a way to see the list of functions in a module, in GHCI?

Question

I find it handy in Python or Common Lisp that you can list a library's contents at runtime. Does Haskell have the same thing, in particular from a GHCI prompt?

Answer 1

GHCi has a :browse command to list the contents of modules:

Prelude> :browse Data.List
(\) :: (Eq a) => [a] -> [a] -> [a]
delete :: (Eq a) => a -> [a] -> [a]
deleteBy :: (a -> a -> Bool) -> a -> [a] -> [a]
deleteFirstsBy :: (a -> a -> Bool) -> [a] -> [a] -> [a]
elemIndex :: (Eq a) => a -> [a] -> Maybe Int
...
Prelude> :help                    
...
   :browse[!] [[*]<mod>]       display the names defined by module <mod>
                               (!: more details; *: all top-level names)
...
