Many other languages have help pages in the command (see help() in python and R). Why haskell doesn't have such a feature?

GHCi has such a command: :doc <function name>

I forgot that this is not the default behavior of GHCi; to get this command, install Hoogle[0][1] and create a file called .ghci in your home directory, with the line: :def doc \x -> return $ ":!hoogle --info \"" ++ x ++ "\"" Regards, Henk-Jan van Tuyl [0] https://hackage.haskell.org/package/hoogle [1] https://wiki.haskell.org/Hoogle -- Folding@home What if you could share your unused computer power to help find a cure?
