 Posted: Tue Dec 30, 2008 9:35 pm Post subject: running the ruby debugger when I start jruby from a java program? |
 |
|
I've learned how to run a jruby program from the console with jruby
and rdebug so that I can attach a NB debugger to the process.
Now I'd like to be able do the same thing when I start one or more
jruby instances from my own Java program.
I can probably take a look at how jruby does it when for example I run this:
jruby --debug -S rdebug-ide -p 7000 --stop -- ar_to_xml.rb
I was just wondering if anyone had already solved this in a simple form.
It would be even cooler to be able to turn debugging on and off
programmatically.

Not sure about your concrete use-case, but simplest is to use
ProcessBuilder. This what NetBeans does when starting 'local' debugger
session.

This needs to be done in the ruby-debug-ide[1] gem, so it will be
possible to call something I described in the blog[2]:
if something_peculiar_has_happened
require 'ruby-debug-ide'
debugger(7000) # 7000 being a port
end
