Hi Waldemar,
The final aim of the aproach is to get a tool in which there will be no syntactic errors during modelling bussiness logic. Recently I've finished very primary version of the tool (0.001:-).
Ah, now that sounds like Haskell might be good for :) Haskell isn't great at writing a GUI and database combination, in my experience. It certainly can, it just tends to be a bit of work. Having said that, Haskell is _great_ for writing domain specific libraries, for plugging together new applications and for modelling business logic. It's likely that your business logic has some standard set of operations, which you combine in some way - this is the thing Haskell excels at - defining small things, and combining them in new ways. The type system will help to ensure that the combinations are good, which again helps reduce errors.
I do not know C#, but what was attracting me to Haskell is - as they say - compact, clean and very functional way of programming.
Yes, a well designed Haskell program will give much better separation of concerns. You can totally separate the logic from the user interface gunk, and it will be more maintainable.
Maybe, but what is still unclear for me: Haskell is wrong for GUI/Database application because of lack of good libraries or because of it's way of programming???
The libraries for GUI programming are not great - they are progressing, and can certainly be used to develop tools, but I don't feel they are "the good stuff" yet. Maybe I'm just setting the bar higher because the rest of Haskell is so nice. The current style of GUI programming in Haskell tends to be in the IO monad, and feel very much like imperative programming. Haskell is perfectly capable of being an imperative programming language where required, but its not as natural as something like C# in this respect. So in answer to your question, I'd say a little of both, but with the optimistic view that one day someone will figure out what a GUI program in Haskell should look like and everyone wlil be happy :) Thanks Neil _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
