I don't know much about JSON but the basic idea seems good.
This is just for error messages, right, not for (say `-ddump-simpl`)?
All compiler output will be formatted as structured JSON. The consumer can filter out logging messages from -ddump-simpl output from warnings as they desire. This information is tracked in the `Severity` argument.
Perhaps `-ddump-X` isn't the right connotation. Maybe `-djson-errors`?
That much is up for discussion. It is named this way as it hooks into the same machinery which controls `-ddump-to-file` and related flags. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13190#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
