#10614: Show constraints in ``Found hole...'' -------------------------------------+------------------------------------- Reporter: bjmprice | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): This would not be hard. * Error messages generation is highly localised, in `TcErrors` * All the info about in-scope constraints is right there in the constraint tree, and is accessible in just the same way that we extract the "relevant bindings". More easily, actually! The only hard bit is deciding exactly what to print, and with what flags to control it. I'm happy to offer guidance.
