Additions:
It will spawn a new thread on the remote process, initialize the Ruby interpreter, start a new DRb server that exposes an expression evaluator object, and advertises the DRb server URI on Bonjour.
A client is provided, inject.rb, that waits on Bonjour for the DRb server URI, connects to it, then either executes a given Ruby script or starts an IRB session.

Additions:
RubyInject is especially useful when combined with RubyCocoa. You can at runtime inject RubyCocoa into an Objective-C application and start introspecting and messaging its objects:
$ open -a textedit
$ ps auxwww | grep TextEdit | grep -v grep

$ sudo ruby inject.rb 69194

= RubyInject =

RubyInject is a Mac OS X framework that allows you to inject at runtime the Ruby interpreter into any running application, using the mach_star∞ mechanism.

It will spawn a new thread on the remote process, initialize the Ruby interpreter, start a new DRb server that exposes an expression evaluator, and advertises the DRb server URI on bonjour.

A client is provided, inject.rb, that waits on bonjour for the DRb server URI, then connects to it.

Requirements

Mac OS X 10.5 or later.
RubyCocoa 0.13.0 or later.
