Subject: [ruby-talk:14052] OO

I'm new to Ruby, and am just starting my first app - coming from a C and
Perl background I'm starting to have OO-related questions.  Are there any
books that people would recommend to get an idea at good practices?

For example - I have built an Options class, which when instantiated takes
a filename, which contains x=y lines, and acts a bit like a Hash - I would
have thought this would be a fairly common object that programs have.

My question would be how are parts of a program supposed to talk to this
Options object?

 - I could instantiate an Options object and then pass it to each object
   as one of its initialization parameters
 - I could instantiate an Options object and place it in $OPTIONS so that
   each object could access that object directly
 - I could instantiate an Options object and store it in a Resources class
   using a class method, and then use another class method to read the
   options back, e.g. Resources.options(...)
 - I could make Options not instantiatable at all and just have class methods
   to load and access the options

Or something else...?  Any advice appreciated.


Best wishes, James
