I dream of mostly generated bindings for Haskell to the native windowing
toolkit.
Eclipse's SWT proves, this is a viable path.

See my proposal here:

RE: [Haskell-cafe] Re: Idea for a very simple GUI llibrary

2009-11-23 Thread Sam Martin 

Thinking of a parallel with Java for a second, is there a GUI library out there 
that's structured like Java Swing? Meaning, there is a GUI library that has a 
small platform-specific GUI foundation (e.g. a per platform implementation of 
the core AWT functionality) and the rest of the functionality is pure haskell?

Supporting cross platform guis is often a bit ... complicated. Java attempted 
to resolve their debug-everywhere nightmare with AWT by making the per-platform 
bit as small as possible, and building everything else in Java.

I guess in theory gtk and wxWidgets take on this support burden, but you do get 
some fairly hefty imperative apis as a result. Perhaps it would make sense to 
focus efforts on stabilising a small 'core gui' library that can act as the 
foundation stone for all manner of pure haskell gui libraries?*

Or perhaps this already exists?

Just a thought.

Cheers,
Sam

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?
