Idle Hacking

If you have a need to execute Python within Ruby this might be interesting to you.

Executing python commands:

  #!/usr/bin/env ruby
  require 'rpy'
  Py.start # starts the python interperter

  output = "hello world"

  Py.run %Q(print "#{output}")

  Py.stop # stops the interperter

Retrieving a result set from python:

  require 'yaml'
  require 'rpy'
  Py.start

  result = YAML.load( Py.run( %Q(_rpython_result = {'hello':1,'world':2}), :serialize => 'yaml') )

  puts result['hello']
  puts result['world']

  Py.stop
