tracepoint_for_method_hooking

🏗️ Instrument Code with TracePoint Hooks

Use TracePoint to hook into runtime events (method calls, class definitions, etc.) for advanced instrumentation, profiling, or custom logging.

trace = TracePoint.new(:call) do |tp|
  puts "Called #{tp.defined_class}##{tp.method_id}"
end

trace.enable

class Sample
  def greet; puts 'Hi'; end
end

Sample.new.greet
trace.disable
