On windows, trace prints out lines without proper line endings
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
(actuallySimplify.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?
