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.

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?
