[Haskell-cafe] Trouble with Debug.Trace when using a library
My project is split in two packages, A and B, where B uses A. All together, there are about 100 haskell modules. Currently, there seems to be a loop somewere, that only seems to occur when working with rather large datastructures. I use trace (from Debug.Trace) to see what exactly is going on. As long as I trace functions from B, trace works as expected. However, at some point I need to trace into functions supplied by package A. In package A I have a function like this: (I have simplified the function) fA :: SomeInput - SomeResult fA a = let x = f a in trace (Entering fA) x (The function f is defined in package A) In package B, I have a function like this: fB :: SomeInput - SomeResult fB a = let x = fA a in trace ( Entering fB) x At runtime, I get the message Entering fB and then nothing more. a lot of cpu is used, but no more output. I have made some wrappers like the ones above. As long as they are in the same package, trace works fine. However, when entering a function from the other package, there is no more debug output. This is very anoying. Anyone some suggestions? Is this a bug? I use the haskell platform 12.4.0.0 on a windows 7 machine. -- View this message in context: http://haskell.1045720.n5.nabble.com/Trouble-with-Debug-Trace-when-using-a-library-tp5730157.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hi, Hackage seems to be down. Is there anyone out here who knows how to get it online again?

[Haskell-cafe] proxy settings with simpleHttp
Hi, I am fiddling around with the package http-enumerator to download web pages. I was used to `simpleHttp` do do that. However, I would like to infuence the proxy settings, because sometimes I am behind a firewall. Is there a simple way to do this? Thanks!

Re: [Haskell-cafe] What library package fulfills these requirements?
Thanks for the link. I enjoyed it. It is quite a different approach as Simon had in the presentation I mentioned. Gives me food for thought, which is good. -- View this message in context: http://haskell.1045720.n5.nabble.com/What-library-package-fulfills-these-requirements-tp4945125p4948604.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] What library package fulfills these requirements?
This is great stuff. I specifically like the interaction part. Hands on experience, whilst skipping the wow-stuff (well, I will mention the possibilities, supplying some links, but no more than a couple of minutes.). And as side effect I now have to get acquainted to github. Like it.

[Haskell-cafe] skin info of haskellwiki
Hi, I would like to use a copy of the hawiki skin for http://ampersand.sf.org my projects mediawiki . I like the way the front page of www.haskell.org works. It uses a mediawiki skin, that is customized for the haskellwiki. However, it used to be http://www.haskell.org/haskellwiki/HaskellWiki:Site_software published , but I find broken links. Is there anyone that could help me out? thanks! -- View this message in context: http://haskell.1045720.n5.nabble.com/skin-info-of-haskellwiki-tp3392503p3392503.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Problem with linking HDBC-ODBC
Hi Yesterday I upgraded to the new version of hdbc-odbc (2.2.3.1.). Then I rebuilt my own project, but the linker gives an error: . . .
