= ruby-debug-base for JRuby

== Overview

(j)ruby-debug-base provides the fast debugger extension for JRuby interpreter.
It is the same as ruby-debug-base native C extension from ruby-debug project
(http://rubyforge.org/projects/ruby-debug/), but for JRuby.

== Install

(j)ruby-debug-base is available as a RubyGem:

   jruby -S gem install ruby-debug-base

== Installation of trunk version

Handy for developers or users living on the cutting-edge.

$ cd ~/tmp
$ svn co svn://rubyforge.org/var/svn/debug-commons/jruby-debug/trunk jruby-debug
$ cd jruby-debug
$ rake gem
$ jruby -S gem install -l pkg/ruby-debug-base-0.10.3-java.gem 
$ jruby -S gem install columnize
$ jruby -S gem install -r ruby-debug -v 0.10.3 --ignore-dependencies

== Usage

The usage is then the same as with native ruby-debugger, but you might need to
force JRuby which has to run in interpreted mode. Simplest usage is:

  $ jruby --debug -S rdebug <your-script>

Or easier, you might create 'jruby-dm' ('dm' for 'debugger-mode'):

  $ cat ~/bin/jruby-dm
  #!/bin/bash
  jruby --debug "$@"

Then you may run just as you used to:

  $ jruby-dm -S rdebug <your-script>
