title: How do I get ruby to print a full backtrace instead of a truncated one?
body: <p>When I get exceptions, it is often from deep within the call stack.  When this happens, more often than not, the actual offending line of code is hidden from me:</p>
  
  <pre class="lang-none prettyprint-override"><code>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
  </code></pre>
  
  <p>That "... 8 levels..." truncation is causing me a great deal of trouble.  I'm not having much success googling for this one:  How do I tell ruby that I want dumps to include the full stack?</p>
