#9995: :info enhancements -------------------------------------+------------------------------------- Reporter: shachaf | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.4 Component: GHCi | Operating System: Unknown/Multiple Keywords: | Type of failure: None/Unknown Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- `:info` is a very useful ghci command, but there are several improvements that could be made: * It would be useful if `:i` showed not only which module a name is defined in, but which module(s) it was imported from in the current session. * A variant of `:i` that just prints a definition, rather than a definition and all instances, would be useful in many cases. E.g. `:i Show` prints the definition of `Show`, but then it prints so many instances that the definition is scrolled way off the screen. * `:i ->` is a parse error; it should behave like `:i (->)`, the way it works for other type-level operators. * hvr had some more suggestions: "finding out which package a module belongs to", "and what module an 'as'-alias is associated with". (Currently I think modules are out of `:info`'s scope, but perhaps it would be a useful addition.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9995 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
