Dependence issue

Hello. I have some trouble with HDBC-mysql package ( http://hackage.haskell.org/package/HDBC-mysql). It depends on base (<4), but in GHC 7 - base 4.3.1. I download a HDBC-mysql package and change dependence in .cabal file to base (<5). It works fine. But I want to build another package that depend on HDBC-mysql and cabal check dependencies from the hackage, where is HDBC-mysql depend on base (<4). What I should do?

Changing the dependency isn't enough. You also want to bump the version number (say, A.B.C.D into A.B.C.D.1) and make your project depend on the bumped version. This way cabal wont find that version anywhere but in installed database and will continue just fine. If the library works fine under base-4 you might also contact the developer so that he can upload the new version which will allow you to drop that hack altogether. Working with such locally-changed versions can be easier if you try cabal-devel tool or similar. But I think might consider another solution: don't use that library. As HDBC docshttp://hackage.haskell.org/packages/archive/HDBC/2.2.6.1/doc/html/Database-H...says: ODBC Available from http://software.complete.org/hdbc-odbc. Or, to partitipace in development, use git clone git://git.complete.org/hdbc-odbc MySQL MySQL users have two choices: the first is the ODBC driver, which works and has been tested against MySQL on both Linux/Unix and Windows platforms. There is also an *alpha-quality* native MySQL driver available for download at http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HDBC-mysql with a homepage at http://www.maubi.net/~waterson/hacks/hdbc-mysql.html. So clearly, HDBC developer(s?) think that HDBC-odbc is the way. Best regards, Krzysztof Skrzętnicki On Sat, Apr 2, 2011 at 00:46, Alexey G wrote:

Thank you! I already rapport about this issue to the mantainer of HDBC-mysql. 2011/4/2 Krzysztof Skrzętnicki

I'd like to add that while category theory is the foundation of a lot of concepts in Haskell, it is not strictly necessary to understand any CT to follow them. I, for example, write many real world applications in Haskell while understanding, just like you, what a category is. It is not necessary to understand on a categorical level what functors or monads are. You just need to be able to make intuitive sense of the definitions and laws. CT gives you some terminology and some connecting lines between those, but it will not make you a better Haskell programmer per se. However, one shortcoming of the current base library is that some of the expressable connections between categorical concepts are not expressed. For example, Monad is not a subclass of Functor, even though every monad is a functor categorically and given a monad instance it is trivial to write a valid functor instance. This is unfortunate, but doesn't change my point.

While there are only few companies hiring Haskell programmers (most of them work in the financial sector), you can very well use Haskell to increase your own productivity. Greets, Ertugrul -- nightmare = unsafePerformIO (getWrongWife >>= sex) http://ertes.de/

Hello Ramy, Yesod is a tightly integrated web framework, while Happstack is more like a set of libraries for web development. The main difference is that Happstack uses normal Haskell approaches to everything and allows you to use individual components easily, while the idea of Yesod is to add more integration and some own language (by Template Haskell and quasi-quoting) to allow you to write less code. You can be very productive with both of them. If you want more freedom, use Happstack. If you want more integration, use Yesod. Personally I found myself to have shorter development cycles with Yesod, but it has a steep learning curve, because you need to understand Haskell and a few of its extensions well to use it. That's just my opinion, by the way. Others may have made different experiences. Greets, Ertugrul Ramy Abdel-Azim wrote:

I did a market evaluation of Haskell and Linq and found the following: - there are page after page of Ling/C# jobs... - I only saw 1 Haskell job... It 'begs the question': is some commercial organization going to implement Haskell as a product [I don't think it will be Microsoft, since they have introduced F#]...

Good morning, Thanks for the advice. I sent an email to Zvon and volunteered to help them with the examples of Haskell functions in their "Haskell Reference Page" The projects that I envisage are: - I tried to get TK installed but was unable to do so, if someone is working this install, I would be willing to test it for them... - If anyone is working on a web front-end to Haskell, I would be willing to participate... Good day

I would pick a project and contribute a patch to it, or start one of your own. -deech
