This may not be exactly what you are looking for, but maybe it is.
I have been looking for a way to create a read/write interface into
an application such that I can send it commands and read the results.
There seems to be a lot of people asking for this and I have read
a lot of responses on ruby-talk, but most of the threads end before
a final solution is obtained. So far, the link below looks the
most promising:
That’s an old post. I believe popen itself now supports bi-directional
communication natively.
a = IO.popen(“nroff -man”,“w+”)
Thread.new do
while line = gets
a.print line
end
a.close_write
end
while line = a.gets
print “:”, line
end
a.close_read
(This works under Unix for version 1.6.8, I seem to recall that it was fixed
for Windows in 1.7.something)
Regards,
Brian.

There are people so addicted to exaggeration that they can’t tell the
truth without lying.
