Let's try scripts and applications of samples.
First, try to execute a RubyCocoa application which has already been built. In Finder, open '/Developer/Examples/RubyCocoa' folder and double-click SimpleApp. Or type following on command line:
% cd /Developer/Examples/RubyCocoa % open SimpleApp.app
on command line (Terminal)
You can write a script for command line with RubyCocoa. Now, let's try to execute a simple script in sample directory.
% cd /Developer/Examples/RubyCocoa % ruby fontnames.rb # fontname print to stdout. % ruby sndplay.rb # system sounds play in order. % ruby sndplay2.rb # system sounds play in order with short interval.
For Mac OS X 10.2 or later users, furthermore:
% echo Hello World | ruby speak.rb % head -5 speak_me.txt | ruby speak.rb
This will be interesting. When you execute speak.rb without arguments, the Mac will read all the text you type until 'control-D' is input. This script uses the AppleScript (and AppleEvent) interface which has been implemented since Mac OS X 10.2.
Next, try scripts with windowing.
$ ruby HelloWorld.rb # window and buttons $ ruby TransparentHello.rb # transparency! $ (cd Hakoiri-Musume && ruby rb_main.rb ) # puzzle game
Build a Makefile-based RubyCocoa application
The next example is Makefile-based. Type this to build:
% cd /Developer/Examples/RubyCocoa/Hakoiri-Musume % make
Now launch the application:
% open CocoHako.app
or double-click 'CocoHako' in the Finder.
Build a Xcode-based RubyCocoa application
The next example is Xcode-based. Type this to build it:
% cd /Developer/Examples/RubyCocoa/simpleapp % xcodebuild % open build/SimpleApp.app
You can build and run the application in Xcode, too. Launch the application:
There are various other samples. Please read and try them. Have fun!
HelloWorld.rb is a sample script for PyObjc that was translated from Python into Ruby.
TransparentHello.rb appears in the article of 'Dr. Dobbs Journal, May 2002' written by Chris Thomas.
RubyRaiseMan and RubyTypingTutor is a tutorial application in 'Mac OS X Cocoa Programming' that was translated from Objective-C into Ruby.
MyViewer is a sample in Japanese book 'Guide of Mac OS X Programming - Objective-C' that was translated from Objective-C into Ruby.
