I'm starting to teach my 7-year-old programming in Ruby, but unlike Scheme or Python or Logo, there doesn't seem to be a graphical interactive environment, such as DrScheme or Livewires. It should be easy to create one, and I've made a start using Tk and irb. I've come across what looks like an ommission in irb: The IRB::Irb constructor takes optional "input_method" and "output_method" parameters. I've created an InputMethod subclass that reads commands from a GUI window, which works, but the output method is ignored - it's passed to the IRB::Context object, but never used. It looks like something like the following is missing: module IRB class Context def output( str ) @output_method.print( str ) end end class Irb def printf( *args ) @context.output( sprintf( *args ) ) end end end By doing that, I can then direct irb's output to my GUI object. How should this get fixed in irb?
