RE: [Haskell-cafe] Re: Idea for a very simple GUI llibrary
I dream of mostly generated bindings for Haskell to the native windowing toolkit. Eclipse's SWT proves, this is a viable path.

[Haskell-cafe] Re: Idea for a very simple GUI llibrary
Nice idea. I will try it if you write runGUI :-) Sure, just let me know :) If this is to be done, I think it's better that the person writing the Haskell code do not write runGUI, so the implementation details wouln't discourage ideas that make life easier for users. This is an imperative style library. For more Haskellian GUI library ideas, see Fruit (http://www.haskell.org/fruit/) and TVs (http://www.haskell.org/haskellwiki/TV). They may not pass the builds constraint :-P I do remember looking at TVs and also Fudgets as sugested by Keith. But there's a unfilled hole for a library that's conceptually simple. I believe that with the library I described users (begginers in Haskell?) could even use QuickCheck and HUnit with their GUI code.

Minor aside. - Could be the first GUI to build on hackage :) If you have wxWidgets installed, the new fully Cabalised wxHaskell builds just fine. It's quite handy/refreshing for 'cabal install wx' to finally just work :-) Unless you mean build on the Hackage server which should also be possible in principle, although the wxHaskell folks may want to have a quick look at http://hackage.haskell.org/packages/archive/wxcore/0.12.1.2/logs/failure/ghc-6.10 -- Eric Kow http://www.nltg.brighton.ac.uk/home/Eric.Kow PGP Key ID: 08AC04F9 signature.asc Description: Digital signature ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Re: Idea for a very simple GUI llibrary
Hi folks, my name is Juan Maiz and i'm starting to study Haskell (again). Is anyone from Brazil in the list?i I'm currently reading The Haskell Road to Logic, Maths and Programming and having a lot of (geek) fun. By the way, i found this: http://www.mail-archive.com/haskell-cafe@haskell.org/msg45406.html . It was sent by Mattias Bengtsson. I made something similar using Ruby's Treetop, with the difference that my concern was to validate and generate truth tables for formulas using Unicode. So... my first noob question to the list: What is the difference of Unicode support in HUGS and GHCI ? In GHCI I can do something like: (∧) = () Prelude True ∧ False *False* (The carachter is the unicode for conjunction U+2227) But in HUGS i can't. It says: ERROR conjunction.hs:1 - Unrecognised character `\8743' Somebody?

Yeah, I found many pages about it (some making fun of a interpreter that follows all H98 spec). But i'm still crawling to understand who is who and what are the pages to get help in Haskell community :D And well, tha's bad, i've really enjoyed Hugs, but i'll have to use GHC instead :D Thanks.

I believe the plan I sugested in the begining of the thread could be easily made into what you want. It could not be, however, as powerfull as the mainstream libraries.
