I'm not sure if this is the right forum to raise this issue, but: Trying out the Syntastic plugin in Vim, I've found that it displays confusingly over-verbose error messages that contain unnecessary information about the module location of identifiers -- e.g.: Config.hs|13 col 7 error| Couldn't match type `(Config.ConfigElem, GHC.Base.String)' with `[GHC.Types.Char]'Expected type: [GHC.Base.String] -> containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.String Actual type: [(Config.ConfigElem, GHC.Base.String)] -> containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.StringIn the expression: Data.Map.Strict.fromList :: [GHC.Base.String] -> containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.StringIn an equation for `Config.foo': Config.foo = Data.Map.Strict.fromList :: [GHC.Base.String] -> containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.String Syntastic uses the output from "ghc-mod check" to generate this, and in turn I think ghc-mod relies on ghc, since options can be passed to ghc from ghc-mod using the -g option flag. Does anyone know of a way to modify the behaviour of Syntastic/ghc-mod/ghc to produce output that's more readable?
