#12927: Colorized error messages result in hard-to-read .dump-* files -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: #8809 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Rufflewind): Another workaround would be to pass `-fdiagnostics-color=never` to ghc. I think the right fix would be to not output ANSI color codes except when the destination is stderr. It's a bit tricky though because I'm not sure how to detect this from within `mkLocMessageAnn`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12927#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
