Hello, I'm writing a program for plotting vectorial functions and maybe something else in the future. My goal is to be able to have the following usage: Prelude> :l Galo.hs Prelude Galo> show3Dvec (\t -> (t, t, 0)) [0.0,0.01 .. 1.0] * shows graph * Prelude Galo> show3Dvec (\t -> (t, t**2, 0)) [0.0,0.01 .. 1.0] * shows new graph * I already done something, the main module can be found here: http://github.com/aflag/galo/blob/0a54a53db0f66384cfc0775f12582931d0fb4205/G... The whole project is found here: http://github.com/aflag/galo/tree/master I think mainLoop is somehow responsible to exit the whole thing. I tried to even call that function through forkIO. But didn't work quite well: my terminal started behaving really weird after I closed the window. Could you explain me what is going on and what should I look into for understanding how to solve the issue? []'s Rafael

I've had issues with ghci and opengl... I usually have to compile my programs before they will run. I'm not sure why that's the case, but I too get strange window behavior (sometimes it freezes, other times it doesn't even show up). If you're on a Mac and would like help compiling to a .app folder, let me know and I can post how I did that.

Duane - yes, please. I've been wondering how to compile to a Mac .app structure. Also, anyone have any hints about distributing Haskell apps for mac, when you know the target will certianly *not* have a GHC environment on it? Thanks --ts On Mar 21, 2009, at 2:18 PM, Duane Johnson wrote:

GHC statically links everything, so you don't need the GHC environment to run the app.

Neat, thanks for that tip Peter. It looks like mkbundl does everything I do manually, and more. But just for the record, in case anyone (Scott?) wants to do it the hard way... :) 1. Download the macosx-app shell script from wxhaskell. Make it executable (i.e. "chmod a+x macosx-app") 2. Run "macosx-app [executable-filename]", e.g. "macosx-app Playground" 3. Run "open [generated app directory]", e.g. "open Playground.app" I also blogged about it here. Duane Johnson http://blog.inquirylabs.com/ On Mar 24, 2009, at 4:48 PM, Peter Verswyvelen wrote:
