#8959: GHCi should honour UnicodeSyntax -------------------------------+------------------------------------------- Reporter: Fuuzetsu | Owner: Type: bug | Status: closed Priority: low | Milestone: 7.10.1 Component: Compiler | Version: 7.6.3 Resolution: fixed | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Easy (less than 1 hour) Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | -------------------------------+------------------------------------------- Comment (by nomeata): Sigh: #3217 is not all there is to fix. Independent of GHCi we seem to want error messages from modules with `UnicodeSyntax` printed with that syntax. So we need to instrument `SDoc` in error messages with the settings from where the setting originated. The `dynflags` passed in `SDocContext` does not work for this, as they are the dynflags in scope when the error is printed, i.e. outside the module scope. There is precedence: The `PrintUnqualified` field of `ErrMsg` and later of `PprUser` transports information about how to pretty print stuff from the location of error to when its `SDoc` is rendered. I added a `Bool` there to indicate whether `UnicodeSyntax` should be used and it seems to work, but I’m not satisfied with this design. Stored the change in the `wip/T8959` branch, see [changeset:4a4e684f4/ghc]. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8959#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
