#4879: Deprecate exports -------------------------------------+------------------------------------ Reporter: basvandijk | Owner: Type: feature request | Status: new Priority: high | Milestone: 7.8.1 Component: Compiler | Version: 7.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by igloo): I've added the beginnings of a patch for this. It needs some polishing, but basically works. In essence, warnings are parsed in export lists, and kept in `AvailInfo` and then `Provenance`. When giving deprecation warnings, we check to see whether any provenance is warning-free, and if not then we print all the warnings. I think we probably want to parameterise `AvailInfo`; in particular, rather than {{{ addAvailInfoWarnings :: Map Name WarningTxt -> [AvailInfo] -> [AvailInfo] }}} we should have {{{ addAvailInfoWarnings :: Map Name WarningTxt -> [AvailInfo Name] -> [AvailInfo NameWarn] }}} `bestImport` in `extendImportMap` should probably be trying to find an import without a warning, too. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4879#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
