client()

Lets an object that will forward method calls to the breakpoint client. This is useful for outputting longer things at the client and so on. You can for example do these things:

client.puts "Hello" # outputs "Hello" at client console
# outputs "Hello" into the file temp.txt at the client
client.File.open("temp.txt", "w") { |f| f.puts "Hello" }

  if Breakpoint.use_drb? then
    sleep(0.5) until Breakpoint.drb_service.eval_handler
    Client.new(Breakpoint.drb_service.eval_handler)
  else
    Client.new(lambda { |code| eval(code, TOPLEVEL_BINDING) })
  end
end
show_call_stack(depth = 10)

Prints the call stack.

  base = Pathname.new(RAILS_ROOT).cleanpath.to_s

  end

end
show_source_list(context = 5)

Prints the source code surrounding the location where the breakpoint was issued.

  start_line, break_line, result = source_lines(context, true)

    mark = (start_line + i == break_line ? '->' : '  ')
    client.puts("%0#{offset}d%s#{line}" % [start_line + i, mark])
  end
  Pathname.new(@__bp_file).cleanpath.to_s
end
source_lines(context = 5, return_line_numbers = false)

Returns the source code surrounding the location where the breakpoint was issued.

  end_line = break_line + context

  result = lines[(start_line - 1) .. (end_line - 1)]

  if return_line_numbers then
    return [start_line, break_line, result]
  else
    return result
