Hi.

Ok. When can we expect a patch? Will it be incorporated into the next =
stable release? The reason for asking is that we're migrating from Hugs =
to using GHC(i) in our basic Functional Programming course. And since =
all our lab machines are Windows based it is imperative that this works =
correctly.

Thanks, Calle

  Allright, thanks - this a bug in the GHCi UI frontend. When
  given a filename via a :load command or the cmd-line it
  processes the filename(s) using Prelude.words, which isn't
  the right thing to do.

    Hi

    Thanks for the answer. It appears as if XP calls ghci via

    "p::\ath\to\ghci" "c:\Documents and Settings\foo\...."

    i.e. with quotes.=20

    Trying to start ghci via cygwin using any of=20

    $ ghci Test\ with\ spaces/Test.lhs=20
    $ ghci Test\ with\ spaces\\Test.lhs=20
    $ ghci "Test with space/Test.lhs"

    $ ghci "Test with space\\Test.lhs"

    will give the error: can't find module `Test' (while processing =
"Test")

    Testing=20

    $ ghci Test\ with\ spaces/Test.lhs=20
    $ ghci "Test with space/Test.lhs"


    under Linux gives the same error.=20

    Hence there seem to be something strange about pathnames containing =
spaces under GHCi.

    However trying the same thing under GHC works like a charm under =
both cygwin and Linux.

    Any ideas?

    /Calle

      Hi thee,

      this is most likely due to the XP shell invoking 'ghci' as =
follows:

        p:\ath\to\ghci c:\Documents and Settings\foo\....

      which makes it look as if multiple arguments are given on the
      command-line (indeed, that's what the argv vector will contain.)

      The registered file assocations for .hs and .lhs takes care of =
quoting
      the filename argument, so I'm not sure this is worth fixing.

      --sigbjorn

      Enterprising souls may want to have a look at the Registry key

        HKEY_CLASSES_ROOT\Unknown\shell\openas\command

      and look at how the %1 arg is quoted (or not)....

        Hello.

        I am having a problem using the Open with ... on haskell-files =
under WinXP. The problem is this: create a file on my desktop and then =
right-click and try to open it using Open with -> ghci. I get the =
following error message:

        can't find module `C:\Documents' (while processing =
"C:\\Documents")

        Obviously GHCi incorrectly handles white space in the path. If I =
run under Cygwin I can use a script like:

        c:\\ghc\\ghc-5.04.2\\bin\\ghci `cygpath -d $1`;

        But how do I solve this if I'm not using cygwin?=20

        Thanks, Calle
