Comment (by guest):
i've got a minor patch that extends ghci's :info to handle module names as
well, so
{{{
Prelude> :i Prelude Data.Maybe Distribution.System Data.Array
Data.Sequence
module Prelude is in package base
module Data.Maybe is in package base
module Distribution.System is in package Cabal-1.3
module Data.Array is in package array-0.1
module Data.Sequence is in package containers-0.1
}}}
that seemed to be the most obvious place to put it, because both i and
haskell modes tend to use ghci a lot, and i often wondered why :info
<module> didn't work. and with 'ghc -e', any ghci command is as good as a
ghc option. it only gives information on modules in exposed packages, so
{{{
Prelude> :i GHC
Top level: Not in scope: type constructor or class `GHC'
Prelude> :set -package ghc
package flags have changed, ressetting and loading new packages...

}}}
would this help with your request?
