Error debugging jruby

just trying to get up to a breakpoint in a Intellij Idea Jruby project.
Any help/i nsgiht is appreciated. Trying to evaluate for our
organization using Jruby to deploy our Ruby projects o the JVM and
perhaps later tap into Java libs.

I’m running on :

Intellij IDEA 11.1.4
Jruby 1.7 + JRE 64

Mac OS X 10.8.2

java -version
openjdk version “1.7.0-internal”
OpenJDK Runtime Environment (build 1.7.0-internal-b00)

I would suggest using pry, especially if you’re evaluating. You could
actually use pry to figure out where your trace failed.

Add the following single line of text where you wish to have a
breakpoint:

require ‘pry’ ; binding.pry

You’ll be in the right context, perform your java exploration, hit
CTRL-D to jump back to execution.

Pry saved me on a big project recently on jruby, where an issue would
occur after 25mn of runtime. Once you realize the faulty block can
have a rescue calling pry, you’re 2mn away from fixing the bug. No ide
involved…

interesting , I’ll check it out. I will add that part of evaluating for
us has to be whether one can use something within the confines of an
IDE. That’s part of my Smalltalk tradition or baggage depending on
which way one wants to think of it.

I wonder if this would work from within IDEA? i.e. doing a run in IDEA
not a debug . I’ll try it out.

BTW, I should conclude by letting folks know that my problem has been
resolved. The issue was that I needed to install the following:

ruby-debug-base pre into jruby , which I did via the command line, I
also then had to within IDEA to an upgrade to that gem version. Once
that was done , I was good.

thanks for the feedback.
