Hi everyone.
I am trying to execute a ruby script from within a Cocoa
application. I want to use NSTask (any better ideas?).
My scripts outputs its progress by printing single lines on standard
out containing percentages (e.g. "15%"). How can I update my
application continuously depending on that progress? (for progress
bars and other output)
Thank you a lot,
Yann
Take a look at AMShellWrapper (http://www.harmless.de/cocoa-code.php).
Another problem is that by default stdout is buffered, so you'll need
to turn that off in your Ruby code to get line-by-line output
(STDOUT.sync = true).
