Wojtek, precise wording is important to us. We make no claim that "Haskell is great for GUIs", only that it is probably capable of carrying a great library for expressing GUIs. This distinction is important because it gives advice on how to solve the problem -- is there some inherent defect in the language and its semantics that makes it difficult, or is the problem more on of manpower?
GUIs are hard, in any language. ----------------------------------------------------------- http://www.emarcus.org/papers/gpce2009-marcus.pdf http://www.cs.uic.edu/~hinrichs/papers/hinrichs2011plato.pdf I am looking for solutions on a Haskell list, because I think chances of finding them here are higher than elsewhere. So let me ask again, any ideas on how would you write down rules for: text field lengths or numeric field ranges, in such a library, for a start?
Similar for the term "GUI". Apparently, you are interested in a narrow aspect of GUI programming -- input forms and validation. Which is totally fine, but not nearly as broad as GUI programming in general.
You are totally right here. I should have said I meant Web UIs, mostly interactive forms. -- Wojtek
