Matching word boundaries in Text.Regexp
I would like to match word boundaries in a regular expression but this doesn't seem to work with Text.Regex in GHC 6.4.2. The regular expression looks something like: \\b(send|receive)\\b to match either the keyword send or the keyword receive but not the word sending. Neither works \ and \ for matching the beginning and end of a word. Thanks for any help, Bernd ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
ghci confused by hi files
I have observed the following weird behavior:
When I define an instance of a certain MPTC
in a separate module from the definition of
the class, ghci's ability to recognize the
methods of the class seems to vary depending
on whether or not hi files exist for the modules.
I am using the current Debian build of GHC 6.6.
Below are a set of three files that reproduce the
behavior, and a shell session that demonstrates
it.
Before I compile the program, ghci works fine.
After I compile with ghc - thus generating hi files -
ghci gets confused. Then I delete the hi files
and everything is fine again.
Thanks,
Yitz

Re: No intellisense in Visual Haskell
Visual Haskell is sensitive to the file name - module name mapping. For the case of Main there could be only one module with this name for a given package and I usually name it Main.hs. For the case of Main there could be a special handling in Visual Haskell because the Cabal description keeps its file name but this is not implemented at the moment. Cheers, Krasimir On 1/15/07, Sittampalam, Ganesh [EMAIL PROTECTED] wrote: OK, I found the problem while trying to make a cut-down test case. I had a module called Main, but the file was called FooMain.hs - this was causing all the intellisense for every project in my solution to break. I've worked round it by renaming my module to FooMain and passing -main-is in the GHC options, but I'd be inclined to view this as a bug, as I think this is a fairly standard way of working with modules - what do you think?

Re: HEAD ghci crash on ppc OS X
Argh ... gmail totally mangled that patch. (The line that starts with loadObj(image) needs to be part of the previous line).
