- # This will pop up an interactive ruby session at a
- # pre-defined break point in a Ruby application. In
- # this session you can examine the environment of
- # the break point.
- #
- # You can get a list of variables in the context using
- # local_variables via +local_variables+. You can then
- # examine their values by typing their names.
- #
- # You can have a look at the call stack via +caller+.
- #
- # The source code around the location where the breakpoint
- # was executed can be examined via +source_lines+. Its
- # argument specifies how much lines of context to display.
- # The default amount of context is 5 lines. Note that
- # the call to +source_lines+ can raise an exception when
- # it isn't able to read in the source code.
- #
- # breakpoints can also return a value. They will execute
- # a supplied block for getting a default return value.
- # A custom value can be returned from the session by doing
- # +throw(:debug_return, value)+.
- #
- # You can also give names to break points which will be
- # used in the message that is displayed upon execution
- # of them.
- #
- # Here's a sample of how breakpoints should be placed:
- #
- # class Person
- # def initialize(name, age)
- # @name, @age = name, age
- # breakpoint("Person#initialize")
- # end
- #
- # attr_reader :age
- # def name
- # breakpoint("Person#name") { @name }
- # end
- # end
- #
- # person = Person.new("Random Person", 23)
- # puts "Name: #{person.name}"
- #
- # And here is a sample debug session:
- #
- # Executing break point "Person#initialize" at file.rb:4 in `initialize'
- # irb(#<Person:0x292fbe8>):001:0> local_variables
- # => ["name", "age", "_", "__"]
- # irb(#<Person:0x292fbe8>):002:0> [name, age]
- # => ["Random Person", 23]
- # irb(#<Person:0x292fbe8>):003:0> [@name, @age]
- # => ["Random Person", 23]
- # irb(#<Person:0x292fbe8>):004:0> self
- # => #<Person:0x292fbe8 @age=23, @name="Random Person">
- # irb(#<Person:0x292fbe8>):005:0> @age += 1; self
- # => #<Person:0x292fbe8 @age=24, @name="Random Person">
- # irb(#<Person:0x292fbe8>):006:0> exit
- # Executing break point "Person#name" at file.rb:9 in `name'
- # irb(#<Person:0x292fbe8>):001:0> throw(:debug_return, "Overriden name")

- # output of your application.
- #
- # You can specify an URI where the DRb server will run at.
- # This way you can specify the port the server runs on. The
- # default URI is druby://localhost:42531.
- #
- # Please note that breakpoints will be skipped silently in
- # case the DRb server can not spawned. (This can happen if

- # But that will still not protect you from somebody
- # reading the data as it goes through the net.
- #
- # A good approach for getting security and remote access
- # is setting up an SSH tunnel between the DRb service
- # and the client. This is usually done like this:

- # $ ssh -L20000:127.0.0.1:20000 -R10000:127.0.0.1:10000 example.com
- # (This will connect port 20000 at the client side to port
- # 20000 at the server side, and port 10000 at the server
- # side to port 10000 at the client side.)
- #
- # After that do this on the server side: (the code being debugged)
- # Breakpoint.activate_drb("druby://127.0.0.1:20000", "localhost")
- #
- # And at the client side:
- # ruby breakpoint_client.rb -c druby://127.0.0.1:10000 -s druby://127.0.0.1:20000
- #
- # Running through such a SSH proxy will also let you use
