Thus if you have a routine Foo() that has a carp() in it, then the carp() will report the error as occurring where Foo() was called, not where carp() was called.</p> <h2 id="Forcing-a-Stack-Trace"><a class="permalink" href="#Forcing-a-Stack-Trace">#</a><a id="Forcing"></a>Forcing a Stack Trace</h2> <p>As a debugging aid, you can force Carp to treat a croak as a confess and a carp as a cluck across <i>all</i> modules. In other words, force a detailed stack trace to be given. This can be very helpful when trying to understand why, or from where, a warning or error is being generated.</p> <p>This feature is enabled by 'importing' the non-existent symbol 'verbose'. You would typically enable it by saying</p> <pre><code class="plaintext">perl -MCarp=verbose script.pl</code></pre> <p>or by including the string <code>MCarp=verbose</code> in the <a href="/5.6.1/PERL5OPT">PERL5OPT</a> environment variable.</p> <h1 id="BUGS"><a class="permalink" href="#BUGS">#</a>BUGS</h1> <p>The Carp routines don't handle exception objects currently. If called with a first argument that is a reference, they simply call die() or warn(), as appropriate.</p> </div> <div id="footer"> <p>Perldoc Browser is maintained by Dan Book (<a href="https://metacpan.org/author/DBOOK">DBOOK</a>).
