#9723: Give Tab warning only once per file -------------------------------------+------------------------------------- Reporter: nomeata | Owner: dalaing Type: feature request | Status: patch Priority: low | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: Phab:D760 -------------------------------------+------------------------------------- Comment (by hvr): I'm a bit dubious about this change. While I understand the intent it seems to the first warning which is not emitted at all occurrences. So tooling can't highlight all offending lines at once, and would need to be made aware that this warning actually affects more lines. So maybe the compromise would be to have a flag to enable warning *all* tab-polluted lines, but have it default to warn only about the first occurence -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9723#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
