i managed to solve what i was attempting.. my goal was rather simple, to be
able to have a python script, call a ruby app, and be able to return a
value from the ruby (child) app to the parent.. blocking/unblocking wasn't
on my radar for now.
ultimately, my goal is to have an app on a master server, with that app
calling the ruby app using the remote functions (rsh/rexec for now).
so, on the master python, i have:
#!/usr/bin/python
#test python script
import re
import os
import sys, string
import os.path
import subprocess
#print "foo"
pp="http://siteanalytics.c ompete.com/xxxx/?metrics=uv"
a = subprocess.Pope n(["/test1/test.rb",pp], stdout=subproce ss.PIPE)
aa=a.communicat e()[0]
qq=aa.split("\n ")
print "qq[8] = ",qq[8]
print "qq[9] = ",qq[9]
print "qq[10] = ",qq[10]
#exit()
and on the child/ruby app:
#! /usr/local/bin/ruby
require 'rubygems'
require '/usr/local/lib/ruby/gems/1.8/gems/firewatir-1.1.1/firewatir'
include FireWatir
a1=ARGV[0]
ff=Firefox.new
ff.goto(a1)
table = ff.table(:id, "dataTable").to _a
#puts table
#puts "blah...."
aa = table[1][1]
puts table[1][1]
#ff.text_field( :name, "q").set("ruby" )
#ff.button(:val ue,"Google Search").click
#puts ff.element_by_x path("//a[@class='l']").text
#ff.close
#puts "hi there"
#return (33)
this pretty much works as it needs to for now...
like i said.. rather simple, as it should be.
so thanks for the help/suggestions from everyone!

hi...a
can someone point me to where/how i would go about calling a ruby app from

from the ruby script.
can be embedded within other applications. Why not implement
something like ruby_exec(), similar to Python's exec, which takes a
string containing Ruby code, and a dict of variables that can be
accessed and updated from the executed Ruby? Then no messing around
with subprocess, XMLRPC, firing up processes, etc. - just create the
string and call it.
(Implementation left as an exercise for the reader.)
