binding_n(n = 0) click to toggle source

Returns a binding of n-th call frame

# File lib/ruby-debug-base.rb, line 255
def binding_n(n = 0)
  Debugger.skip do
    Debugger.current_context.frame_binding(n+2)
  end
end
breakpoint(steps = 1, &block) click to toggle source
Alias for: debugger
debugger(steps = 1, &block) click to toggle source

Enters the debugger in the current thread after steps line events occur. Before entering the debugger, a user-defined startup script is may be read.

Setting steps to 0 will cause a break in the debugger subroutine and not wait for a line event to occur. You will have to go “up 1” in order to be back in your debugged program rather than the debugger. Settings steps to 0 could be useful you want to stop right after the last statement in some scope, because the next step will take you out of some scope.

If block block is given (and the debugger hasn’t been started, we run the block under the debugger.

FIXME: Alas, when a block is given, we can’t support running the startup script or support the steps option.

# File lib/ruby-debug-base.rb, line 237
def debugger(steps = 1, &block)
  if block
    Debugger.start({}, &block)
  else
    Debugger.start unless Debugger.started?
    Debugger.run_init_script(StringIO.new)
    if 0 == steps
      Debugger.current_context.stop_frame = 0
    else
      Debugger.current_context.stop_next = steps
    end
  end
