Creating a Cocoa GUI window with NodObjC

cocoa-hello-world.js

var $ = require('./')
$.import('Foundation')
$.import('Cocoa')

var pool = $.NSAutoreleasePool('alloc')('init')

var app = $.NSApplication('sharedApplication')
var style = $.NSClosableWindowMask | $.NSResizableWindowMask
          | $.NSTexturedBackgroundWindowMask | $.NSTitledWindowMask
          | $.NSMiniaturizableWindowMask

var rect = $.NSMakeRect(50, 50, 600, 400)
var win = $.NSWindow('alloc')('initWithContentRect', rect
                            , 'styleMask', style
                            , 'backing', $.NSBackingStoreBuffered
                            , 'defer', 0)
win('makeKeyAndOrderFront', win)
app('run')

pool('release')

Results in:

I get an error myself

output from command: node cocoa-gui

Segmentation fault
bash-3.2$

I would love to get this cocoa working with node - but can't seem to get any of it to work. Any idea what a Segmentation fault is, what causes it?

@billymoon Which node version? I seem to have the most luck on v0.5.5. Also does even the hello world example in the README work?

I am using node version 0.4.11 which is the latest stable branch. I was not able to install NodObjC with 0.5.6, so switched to the stable one. I will try out the hello world now... And the results... bash-3.2$ node hello-world

{ [Function: id] pointer: { allocated: 0, address: 4928189904 } } bash-3.2$

so no, and I have no idea what this error message means either... I am not 100% sure my node is installed correctly, but seems to work for other things. I have a doubt, because I am not experienced with node, and it's configuration etc... I cloned the node git repo, then switched to branch v0.4.11, and built node. After that, I simply copied the built `node` file to my ~/local/node/bin/ and that seems to work, I get the right version number out of it when I use the node command from anywhere on my system, and it runs other servers. I am not sure about this step though, I was guessing, because I cant seem to find how to correctly install node.

Oh I see what's going on. You're on NodObjC@0.0.3. That version doesn't have a lot of the good stuff. I just published v0.0.7 which gives support back for node 0.4.x. So re-run npm install NodObjC and let me know how it goes.

Seemed to install ok after using "sudo npm install NodObjC" bash-3.2$ npm install NodObjC

@billymoon Come to IRC room #nodobjc on Freenode and I can help walk you through it.

I just got it working - was a problem with my node installation ( http://stackoverflow.com/questions/7437447/how-to-build-and-install-node-js-on-osx-from-git-clone/7438098#7438098) which I solved by completely removing it, the re-installing everything. After that - I had to install NodObjC twice (once before all the other modules like express etc...) - both times with success message, then it all works fine. Hello world and cocoa. Happy days. Thanks a bunch for your help. This is a very exciting project. Javascript is appearing everywhere now - I really like it. Cheers Billy
