I'm sorry, I'm quite confused. GHC already has a `-fwarn-tabs` flag, doesn't it? There are two patches offered above, but I'm not clear what
#9230: Make -fwarn-tabs the default -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: mlen Type: feature | Status: new request | Milestone: 7.10.1 Priority: normal | Version: 7.8.2 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Easy (less than 1 Unknown/Multiple | hour) Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by dfeuer): Replying to [comment:16 simonpj]: the purpose of either is. Maybe I have not ready through this ticket carefully enough. I don't understand that either. The essential ''problem'' we have is that we want `-fwarn-tabs` to be the default, but we have to find some way to get validation to pass when there are currently a lot of libraries in the GHC tree that have tabs but don't invoke `-fno-warn-tabs`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9230#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
