#14188: On windows, trace prints out lines without proper line endings -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Try this on Windows {{{ module Foo where f x = x }}} and now {{{ ghc -c -dverbose-core2core Foo.hs 2> foo }}} Now edit `foo`. You'll see that * Some lines, produced by monadic IO, I think, have CRLF endings (`^M^J`). * But others, produced by `pprTrace` (actually `Simplify.hs` line 220, only have a LF ending (`^J`). The inconsistent line endings confuses emacs, which displays `^M` at the end of all the CRLF lines (ie most of them). This is Jolly Annoying. John Wiegley has made me a special SPJ-only emacs mimor mode that suppresses the annoying `^M` stuff, but that seems like extreme measures. Question: why doesn't `pprTrace` properly terminate its lines? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14188 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
