Hi all, I've come across some code I just can't figure out how to write appropriately. Below is a silly example that demonstrates what I'm trying to do. I don't really have the appropriate vocabulary to describe the issue, so I'll let the code speak for itself. In particular, I'm trying to

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

Hi, Here is a sketch for a library with these properties: - Easy to test. All Haskell code can be tested in a text terminal. Also, testing code that uses the library can also be done without using a GUI. - Extremely easy to document and use. - Not even close to Gtk2hs power, but enough for

Nice idea. I will try it if you write runGUI :-) 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 Luke 2009/11/22 Maurí­cio CA

You should also check out Fudgets and Tangible Functional Programming. Fudgets is a really old Haskell UI library concept; Tangible FP is a recent Google talk about a UI library inspired by Haskell types. 2009/11/22 Luke Palmer lrpal...@gmail.com: Nice idea.  I will try it if you write runGUI
