#8809: Prettier error messages? -------------------------------------+------------------------------------- Reporter: joelteon | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by diatchki): It would be nice if we could refactor GHC so that error messages are kept in some sort of structured format with all information that might be relevant. Then, when printed we could have flags to specify how to render the errors (e.g., "machine form", which would be good for external tools, such as IDEs; or "human form", which could have the nice formatting in the example). I just saw a post about error messages in Elm, which looked pretty, and might give us ideas about formatting: http://elm-lang.org/blog/compiler- errors-for-humans -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8809#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
