Recorder

Recorder is similar essentially a method probe. It records everthing that happens to it, building an internal parse tree. You can then pass a substitute object and apply the recoding to it. Or you can utilize the parse tree.

The only limitation of Recorder is with special operators, like if, &&, ||, etc. Since they are not true methods they can‘t be recorded. (Too bad for Ruby.)

Synopsis

  class Z
    def name ; 'George' ; end
    def age ; 12 ; end

  z = Z.new

  r = Recorder.new
  q = proc { |x| (x.name == 'George') & (x.age > 10) }
  x = q[r]
  x.__call__(z)

produces

  true
