RE: No intellisense in Visual Haskell

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?

Matching word boundaries in Text.Regexp
by Bernd Holzmüller 16 Jan '07

16 Jan '07

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

No intellisense in Visual Haskell
by Sittampalam, Ganesh 15 Jan '07

Hi, I've installed Visual Haskell and am having some trouble with the Intellisense functionality. It works fine on a small project I start from scratch, but doesn't work at all for a bigger project (no tooltips, "Go to Definition" doesn't work, etc etc). Is there any way to debug this?

ghc 6.6.1?
by C.M.Brown 15 Jan '07

Hi, I was wondering when ghc-6.6.1 will be released? I am asking because a patch has been made to the ghc repo to allow multple calls to the ghc.newSession within the API and HaRe depends on this. Regards, Chris.

IOExts problem
by jim burton 15 Jan '07

IOExts seems to be unavailable on my system, whereas I'm guessing it should be since the file /usr/lib/ghc-6.4.1/hslibs-imports/lang/IOExts.hi exists...(wrong guess?) Within ghci I get Prelude> :m IOExts Could not find module `IOExts': it is not a module in the current program, or in any known package. Prelude> I am trying to build the latest version of haskore with ghc 6.4.1 and have edited the Makefile to put in references to the location of IOExts.hi: HC_OPTS = -cpp -i/usr/lib/ghc-6.4.1/hslibs-imports/lang/IOExts.hi IOExtensions.o : /usr/lib/ghc-6.4.1/hslibs-imports/lang/IOExts.hi Now make gives the error: jim@unicorn:~/haskore/Src$ make ghc -c IOExtensions.hs -cpp -i/usr/lib/ghc-6.4.1/hslibs-imports/lang/IOExts.hi IOExtensions.hs:20:0: Failed to load interface for `IOExts': Could not find module `IOExts': use -v to see a list of the files searched for make: *** [IOExtensions.o] Error 1 Is IOExts installed as standard with GHC or do I have to tell it the path to the hi file somehow? -- View this message in context: http://www.nabble.com/IOExts-problem-tf2919193.html#a8158283 Sent from the Haskell - Glasgow-haskell-users mailing list archive at Nabble.com.

Have you looked at the chapter on profiling in the GHC manual yet? http://www.haskell.org/ghc/docs/latest/html/users_guide/profiling.html There's also a very sketchy intro to profiling in the GHC Commentary: http://hackage.haskell.org/trac/ghc/wiki/Commentary/Profiling and you're welcome to improve it. If the above documentation doesn't answer your questions, feel free to reply to this mailing list with more specific questions; it might help to explain exactly what you're trying to find out about your program's behavior.

rfc: colorized Haskell on GHC-Trac
by Peter Tanski 12 Jan '07

12 Jan '07

To anyone who has an interest in reading GHC-Trac: In an idle-procrastination moment I started to experiment with html- colour for Haskell code (using hscolour) on a few Trac pages: http://hackage.haskell.org/trac/ghc/wiki/ReplacingGMPNotes (some blocks, note Cyan-colour for literal integrals ("1")) http://hackage.haskell.org/trac/ghc/wiki/ReplacingGMPNotes/ TheCurrentGMPImplementation (one-line snippets) http://hackage.haskell.org/trac/ghc/wiki/Commentary/Compiler/CmmType (large blocks) What do you think? Better? Worse? Would you rather see a silver/grey background as for other code? Personally I tend to prefer the Orange for top-level function definitions but don't quite know about orange- colour functions as they are used. Most of this is close to emacs- colour codes. For those who are interested in playing around, the easy way to do this is: demarcate a code block: {{{ #!html <pre> <font color=Orange>topLevelFunction</font> ... </pre> }}} Thanks, Peter Tanski

This is an error from the internal GMP library's configure file, $ (top_level)/rts/gmp/configure. If you don't have gmp installed already, the GHC build system tries to build it for you. The build system for gmp is very delicate so I would suggest downloading a separate gmp library and installing that in your /usr/lib directory (for MinGW). The gmp library and header file for MinGW, avaliable from http://cs.nyu.edu/exact/core/gmp/ under 'gmp-static- mingw-4.1.tar.gz'. Once you have the library installed properly, the GHC build system will find it and won't attempt to build gmp. I know it sounds like a workaround--we really ought to ensure the gmp build itself works--but in this case it is the gmp build that fails (swox.org's problem, not ours) and the current gmp system should be replaced soon by another library. (I am working on that but for lack of time I am running a bit late.) Cheers, Peter Tanski

HDirect and GHC-6.6
by Fernand Lacas 12 Jan '07

12 Jan '07

Hello, This is my first post on this mailing list and I hope it will not be too off-topic. My point is that I have worked a little on the porting of the last (0.21) version of HDirect (http://www.haskell.org/hdirect/) to ghc 6.6. I succeeded in compiling the ihc.exe (idl compiler) but I'm now stuck on the boot-strapping of the COM library (which is required to have support for Automation). This seems to come from a new feature of the package management system, which includes the package's name in the interface files (.hi). Alas, on the beginning of this new year (happy new year to you all), I lack time to understand the cabal system to solve this. I've written to the people mentioned in the README (and others), which are supposed to support the library, but got no answer. I assume they are no longer supporting it. Thus, I simply wanted to know if someone on this list, more involved with ghc or haskell's community, would be interested to have the sources files so that, may be in the near future, hdirect could be up to date with ghc, and also that other people could benefit from that small contribution without re-inventing the wheel (my changes are not complex, but rather tedious because I had to track all deprecated libraries, correct a GHC-specific bug). I also think that hdirect build process should be translated to Cabal's setup (it currently uses Makefiles, but the build process is not straightforward, so the adaptation requires a knowledge I do not have of Cabal). Sincerely yours, Samuel P.-S. I do not check this mail on a daily basis, so it is possible I won't answer immediately, but within one or two days.
