#14097: -ddump-json doesn't interact as expected with -ddump-to-file -------------------------------------+------------------------------------- Reporter: mpickering | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: JSON 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 mpickering): Well, the real problem here is that the way things are currently engineered, `-ddump-json` collects error messages for the entire compilation and then dumps them in one go. `dumpSDoc` is set up to dump things on a per-module basis, as such the log files are given the name of the current module they are dumping. Perhaps a better design for `-ddump- json` would be to output a JSON log on a module-by-module basis rather than collecting all the output. This would complicate the implementation a little as the messages would need to be sorted by module. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14097#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
