Ruby Tracepoint - 將掛鉤掛接到open3子進程

Question

我正在玩弄偉大的Tracepoint API，並且我在想是否可以將事件掛鉤附加到使用popen3啓動的ruby進程？

一個例子：

TracePoint.trace(:end) do |e| 
    # Here we do something like logging this event. 
end 


Open3.popen3(cmd) do |stdin, stdout, stderr, thread| 
    # cmd is a ruby cmd, and we want the tracepoint above to apply to it as well 
end 

任何想法？

Answer 1

沒有解決方案popen3，但一個簡單的exec伎倆。
