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?

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
