Hi,
I'm new to RoR and to begin I decided to do a graphic calculator as my
second project.
I plan to use octave to evaluate the expressions, I can't get to
install the octave-ruby gem and for the sake of development speed I'll
be fetching the ouput of "octave --eval" instead.
I found that ruby uses the same command as php to run external
commands, system(), but whether i use system("octave","/usr/bin") or
system("octave"), it will return "true", telling me that the
application was successfully executed.
I can't convert the output to string, either.
What are your recommendations to grab the output from an application?
