Subject: Re: Debugger Debugging Ruby?

You probably have RUBYOPT environment variable set to load rubygems
automatically (it is set up automatically with the 1-click installer).

You can set a breakpoint in the first line of your file as the first
command to the debugger and then continue until you reach it:

c:\TEMP>ruby -rdebug foo.rb
Debug.rb
Emacs support available.

c:/bin/ruby/lib/ruby/site_ruby/1.8/ubygems.rb:4:require 'rubygems'
(rdb:1) b foo.rb:1
Set breakpoint 1 at foo.rb:1
(rdb:1) c
Breakpoint 1, toplevel at foo.rb:1
foo.rb:1:print "hello"
(rdb:1)


HTH,
