1. ブロックのみ

@tracer = TracePoint.new(:a_call, :a_return, :line){|tp|
end

2. skip? メソッド()を追加

@tracer = TracePoint.new(:a_call, :a_return, :line){|tp|
  next if skip?(tp)
end

3. depth を取得

@tracer = TracePoint.new(:a_call, :a_return, :line){|tp|
  next if skip?(tp)
  depth = caller.size
end

4. call_identifier_str を取得

@tracer = TracePoint.new(:a_call, :a_return, :line){|tp|
  next if skip?(tp)
  depth = caller.size
  
  call_identifier_str =
          if tp.defined_class
            minfo(tp)
          else
            "block"
          end
end

5. :call, :c_call, :b_call のみ配列に挿入

@tracer = TracePoint.new(:a_call, :a_return, :line){|tp|
  next if skip?(tp)
  depth = caller.size
  
  call_identifier_str =
          if tp.defined_class
            minfo(tp)
          else
            "block"
          end

  case tp.event
    when :call, :c_call, :b_call
      depth += 1 if tp.event == :c_call
      sp = ' ' * depth
      out tp, ">#{sp}#{call_identifier_str}", depth
    end
  end

6. :return, :c_return, :b_return のみ配列に挿入

@tracer = TracePoint.new(:a_call, :a_return, :line){|tp|
  next if skip?(tp)
  depth = caller.size
  
  call_identifier_str =
          if tp.defined_class
            minfo(tp)
          else
            "block"
          end

  case tp.event
    when :return, :c_return, :b_return
      depth += 1 if tp.event == :c_return
      sp = ' ' * depth
      return_str = DEBUGGER__.safe_inspect(tp.return_value, short: true)
      out tp, "<#{sp}#{call_identifier_str} #=> #{return_str}", depth
    end
  end
