rocky / rbdbgr

A modular, testable debugger for Ruby 1.9

Some cryptic examples.

Running if rbdbgr is installed:

  rbdbgr ruby-program [program args]

To call from inside a Ruby program, there is one-time setup that 
needs to be done first:

    require 'rbdbgr'
    mydbg = Debugger.new()

or if you haven't mucked around with $0 and ARGV, you might try:
    mydbg = Debugger.new(:set_restart=>true))

which will tell the debugger how to "restart" the program.

If you want a synchronous stop in your program call to the
debugger at the point of the call, set opts[:immediate]
true. Example:


  #    ... work, work, work
      mydbg.debugger(:immediate=>true)   # enter debugger here
  #    ... work, work, work

However to enter the debugger on the next event after the 
debugger() call:

  #    ... work, work, work
  mydbg.debugger  # Don't stop here...
  work            # but stop here.

And finally, if you want to debug just a block:
  mydbg.debugger {
  #     ... code you want to debug.
  }
