[OSX] Smalltalk to Cocoa (ObjectiveC) bridge

Hi list.

Pavel,

that's a good idea. I've written a transparent Cocoa interface that uses Smalltalk syntax for NSObject and subclasses. I use it for the native Mac menu bar, native dialogs, native printing, making screenshots and more. Here are a few code examples copied from the package comment:

    NSLocale currentLocale localeIdentifier.

    NSHost currentHost name.

    NSApplication sharedApplication mainWindow
        setHasShadow: false.

    (NSSpeechSynthesizer alloc
        initWithVoice: NSSpeechSynthesizer defaultVoice)
            startSpeakingString: 'Hello, here I am.';
            release.

    NSApplication sharedApplication keyWindow asSurface nsImage TIFFRepresentation
        writeToFile: '/Users/Andre/Documents/screenshot.tiff'
        atomically: false.

I'm using the interface extensively in our music applications. We have plans to contribute the packages in the future (along other MacOS X related stuff), but there are currently more urgent things to do than cleaning up docs and packaging "spin off" releases. I just wanted you to know what's going on. In the meanwhile the above examples may serve as an inspiration.

IIRC, the guys at Heeg have also done a package "ObjC Connect" (?), which I assume is quite similar. Though I don't know whether it is publicly available.

So in any case, starting off from scratch should not ne necessary.

Did anyone play with the idea of providing VisualWorks-to-Cocoa bridge? There're bridges for Python, Ruby, Java and i believe even Squeak. I think having access to Cocoa from within VisualWorks will greatly extend the possibilities for using VW on Mac OSX platform and let one develop much nicer apps.

This surely can be done as community effort. I'm not an experienced OSX developer but have vast knowledge of VisualWorks and have some spare time. Moreover i like Mac OSX very much. Is anyone interested in such project? 

Yours, Pavel

Actually, this has been done at least 3 times that I'm aware of.

* There was/is an ObjCConnect that Heeg did when they did for the  
original port of VW to OSX. I'm not honestly sure where this resides  
at. It may be in the Open Repository or the preview, or not, I don't  
know.
* I wrote a very small/simple variant that I use with Cairo. It's the  
barest bones rudimentary interface that can fetch classes by name,  
and send messages to objects. It is in the Open repository, as  
'ObjectiveCInterface'.
* Andre Schnoor did a more evolved version for his OSX work. It (or  
at least an early version) may be in the Open Repository.

Hi
Where can I find out about bridges for Python? I assume this is about calling
Python from VisualWorks.

Regards,
Ernst
