如何在 Ruby 中获取堆栈跟踪对象? [英] How to get a stack trace object in Ruby?

问题描述

我需要在 Ruby 中获取堆栈跟踪对象；不打印它，只是让它做一些记录和转储以供以后分析.那可能吗?怎么样?

I need to get a stack trace object in Ruby; not to print it, just to get it to do some recording and dumping for later analysis. Is that possible? How?

推荐答案

您可以使用 Kernel.caller 为此.为异常生成堆栈跟踪时使用相同的方法.

You can use Kernel.caller for this. The same method is used when generating stack traces for exceptions.

来自文档:

def a(skip)
  caller(skip)
end
def b(skip)
  a(skip)
end
def c(skip)
  b(skip)
end
c(0) #=> ["prog:2:in `a'", "prog:5:in `b'", "prog:8:in `c'", "prog:10"]
c(1) #=> ["prog:5:in `b'", "prog:8:in `c'", "prog:11"]
c(2) #=> ["prog:8:in `c'", "prog:12"]
c(3) #=> ["prog:13"]
