#10540: Showing type synonym isn't exported by Hoopl -------------------------------------+------------------------------------- Reporter: nimnul | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: | Version: 7.10.1 libraries/hoopl | Operating System: Unknown/Multiple Keywords: | Type of failure: Incorrect Architecture: | warning at compile-time Unknown/Multiple | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Hoopl exports {{{#!hs showGraph :: Showing n -> Graph n e x -> String }}} But it doesn't export `Showing`. This doesn't make sense, as it's a user- supplied function. So to know what I should pass to `showGraph` I can only look at the source. `:i Showing` doesn't work. Below is a patch to export the innocent type synonym: {{{#!patch diff --git a/src/Compiler/Hoopl/Show.hs b/src/Compiler/Hoopl/Show.hs index 8a8b35f..66172b0 100644 --- a/src/Compiler/Hoopl/Show.hs +++ b/src/Compiler/Hoopl/Show.hs @@ -4,7 +4,7 @@ #endif module Compiler.Hoopl.Show - ( showGraph, showFactBase + ( showGraph, showFactBase, Showing ) where }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10540 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
