当我得到异常时,它通常来自调用堆栈中的深层.当发生这种情况时,通常会对我隐藏实际有问题的代码行:

tmp.rb:7:in `t': undefined method `bar' for nil:NilClass (NoMethodError)
        from tmp.rb:10:in `s'
        from tmp.rb:13:in `r'
        from tmp.rb:16:in `q'
        from tmp.rb:19:in `p'
        from tmp.rb:22:in `o'
        from tmp.rb:25:in `n'
        from tmp.rb:28:in `m'
        from tmp.rb:31:in `l'
         ... 8 levels...
        from tmp.rb:58:in `c'
        from tmp.rb:61:in `b'
        from tmp.rb:64:in `a'
        from tmp.rb:67

那个"... 8级......"截断给我带来了很多麻烦.我在这方面没有太大的成功:我怎么告诉ruby我想要转储包含完整的堆栈？
