I just started playing around with Mars which is a bridge from Squeak to Cocoa, which allows Squeak Programms to have a Cocoa GUI.

Pretty nice - however not quite as easy to get installed if you are a SmallTalk newbie like me.

There are installation instructions on the Mars homepage however I couldn't quite follow them, so I enhanced them a little and give you the rundown here:

Instructions

• I downloaded the basic Image from http://ftp.squeak.org/3.10/Squeak3.10.2-7179-basic.zip
• Got the Virtual Machine from ftp://ftp.smalltalkconsulting.com/experimental//Squeak%203.8.21beta1U.app.zip
• Installed basic developer tools by executing <HTTPSocket httpFileIn: 'installer.pbwiki.com/f/LPF.st'.> in a workspace window (select it and hit command-d)
• Then I ran

  Installer universe 
   addPackage: 'OmniBrowser';
   addPackage: 'OmniBrowser-Morphic';
   addPackage: 'OmniBrowser-Standard';
       addPackage: 'OmniBrowser-Refactory';
   install.
  

  to get the basics and
• installed Mars by executing ``` Installer wiresong project: 'ob'; install: 'OB-Monticello'. Installer lukas project: 'omnibrowser'; install: 'OB-Tools'.

Installer ss project: 'Mars'; install: 'Mars'; install: 'OB-Mars'.

After that `OBMarsWorld execute.` replaces the menubar of Squeak with the Cocoa stuff.

:) Have fun!

Oh, and by the way, I just tried this with the dev image available from Damien Cassou at http://damiencassou.seasidehosting.st/Smalltalk/squeak-dev

This image already has most stuff preloaded, so you can just run

Installer wiresong project: 'ob'; install: 'OB-Monticello'. Installer lukas project: 'omnibrowser'; install: 'OB-Tools'.

Installer ss project: 'Mars'; install: 'Mars'; install: 'OB-Mars'. ```

to get Mars installed and then start it by running: OBMarsWorld execute.
