#3452: Show type of most recent expression in GHCi -------------------------------------+------------------------------------ Reporter: ozy | Owner: Type: feature request | Status: new Priority: lowest | Milestone: 7.6.2 Component: GHCi | Version: 6.10.4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by osa1): I'm a new contributor(preparing my first patch) and I'm working on this, currently my patch is this: https://github.com/osa1/ghc/commit/d542b418d913b4aba04e497fb63b70108b058f48 This is probably far from being finished, I'm looking for reviews/comments on this. I'm not very happy with the way it is implemented but for now this is only way I could think. If someone point me a batter way to do I'll happily change my patch. Here's an example output: https://gist.github.com/osa1/6201852 One thing I didn't like about this output is the _it_ part, to me it's not user friendly enough. I think we need to tell user that his value isn't showable so only it's type is shown. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3452#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
