Better way to execute ruby file using Python and How to get ruby console output when ruby file is run from python?

Question

Hi,

I am building a standalone using python. This standaloone should execute a ruby file.

I have read this article - http://www.decalage.info/python/ruby_bridge I have used os.system() which works well. But I have an issue here. If a ruby file has some error, file simply terminates without error. Can you please let me know how to GET ruby console output so that I can display the same in my standalone.

Answer 1

you can use subprocess module

cmd="ruby myrubyscript.rb"                                                                          
p=subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)                              
output, errors = p.communicate()                        

then use the output variable

Just a note, your Python program will be dependent on whether you have Ruby installed or not. If possible, try to do everything in Python.
