Hi there.

I'm using Ruby and the great Processing implementation made for Ruby
(http://github.com/jashkenas/ruby-processing/wikis). The "problem" is
that if you need to run anything of Ruby-Processing, you need to write:

#rp5 run app.rb

Instead of #ruby app.rb

So, what I need is executing the "rp5 run" command from another ruby
application, since I'm generating the Processing document in another
Ruby app which does not use Ruby-Processing.

I'm running Ruby from Mac Os X. Any idea?

or, if you need the output what you ran,
foo=%x{rp5 run foo}
# note, you can use most paired symbols, like () [] <>, or quotes "" '',
#with %x, not just {}
