How does Haskell deal with documentation?

Question

How do I get online documentation in Haskell?

Are there anything as elegant/handy as what Python does below?

>>> help([].count)
Help on bu         


        

Answer 1

Currently, there is no way to view the Haddock documentation within ghci, but there is a ticket for it.

You can however get a small bit of info using the :info command, e.g.

ghci> :i nub
nub :: (Eq a) => [a] -> [a]     -- Defined in Data.List  

so that you at least know where to look for the documentation for a particular function.
