#10874: Implement `:type-at`, `:all-types`, `:loc-at` in GHCi -------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: feature | Status: new request | Priority: normal | Milestone: 8.0.1 Component: GHCi | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- We missed the opportunity to merge this for GHC 7.10 but I hope this can make it for GHC 8.0 See https://github.com/chrisdone/ghci-ng/blob/master/README.md for a description of the new GHCi commands I've started rebasing the changes from Chris' ghci-ng repo against GHC HEAD and pushed the work-in-progress state as branch `wip/T10874`. One blocker right now is the use of SYB to traverse the AST which I don't want to drag into GHC as a dependency. So one thing that needs to be done is rewrite those 20 lines of code without relying on SYB. Other than that some minor polishing needs to be done. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10874 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
