However installing CPAN modules hasn't always been as straightforward as it should be... until <em>cpanminus</em>.</p> <p><code>App::Cpanminus</code>, or just <code>cpanm</code>, is a fast, lightweight, pure-perl CPAN installer. Its features are numerous, including:</p> <ul> <li> <p>No configuration required.</p> </li> <li> <p>Can be run as a regular user; no need for root.</p> </li> <li> <p>Works with <code>local::lib</code> and <code>perlbrew</code> out of the box.</p> </li> <li> <p>Condensed and clarified output.</p> </li> <li> <p>Absolutely no dependencies.</p> </li> <li> <p>Small memory footprint (great for virtual machines).</p> </li> <li> <p>Works with Perl 5.8 or later.</p> </li> </ul> <p><b><a href="http://perltraining.com.au/tips/2012-03-27.html">Read more...</a></b></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=fa9OxWWHQxk:KgVc0OTr2yU:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=fa9OxWWHQxk:KgVc0OTr2yU:F7zBnMyn0Lo"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=fa9OxWWHQxk:KgVc0OTr2yU:F7zBnMyn0Lo" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=fa9OxWWHQxk:KgVc0OTr2yU:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=fa9OxWWHQxk:KgVc0OTr2yU:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=fa9OxWWHQxk:KgVc0OTr2yU:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=qj6IDK7rITs" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=fa9OxWWHQxk:KgVc0OTr2yU:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=fa9OxWWHQxk:KgVc0OTr2yU:gIN9vFwOqvQ" border="0"></img></a> </div>2012-03-27T00:00:00Zhttp://perltraining.com.au/tips/2011-11-08.html<p><code>Test::More</code> provides many great testing functions.

The easiest way to ensure that this is the case, and to protect yourself from introducing bugs in the future, is to create a test suite for your code. Perl has a fantastic testing culture and many great tools to make testing easy.</p> <p>For further information on testing read the <a href="http://search.cpan.org/perldoc?Test::Tutorial">Test::Tutorial documentation</a>.</p> <p><b><a href="http://perltraining.com.au/tips/2011-10-24.html">Read more...</a></b></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=8lh7SJs3Fds:NnfW9xWggHc:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=8lh7SJs3Fds:NnfW9xWggHc:F7zBnMyn0Lo"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=8lh7SJs3Fds:NnfW9xWggHc:F7zBnMyn0Lo" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=8lh7SJs3Fds:NnfW9xWggHc:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=8lh7SJs3Fds:NnfW9xWggHc:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=8lh7SJs3Fds:NnfW9xWggHc:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=qj6IDK7rITs" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=8lh7SJs3Fds:NnfW9xWggHc:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=8lh7SJs3Fds:NnfW9xWggHc:gIN9vFwOqvQ" border="0"></img></a> </div>2011-10-24T00:00:00Zhttp://perltraining.com.au/tips/2011-02-25.html<h2>Comment your code with Smart::Comments</h2> <p>Normally we comment our code so that humans (including ourselves) can understand it later on. However with <code>Smart::Comments</code> it becomes possible to have comments which are not only useful in comprehending our code, but also in <em>debugging</em> our code.</p> <p>With <code>Smart::Comments</code> enabled, when a special comment sequence is seen (<code>###</code> by default) debugging output is produced:</p> <p><b><a href="http://perltraining.com.au/tips/2011-02-25.html">Read more...</a></b></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=ZStppNYGYgo:RkdexS7rKMU:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=ZStppNYGYgo:RkdexS7rKMU:F7zBnMyn0Lo"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=ZStppNYGYgo:RkdexS7rKMU:F7zBnMyn0Lo" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=ZStppNYGYgo:RkdexS7rKMU:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=ZStppNYGYgo:RkdexS7rKMU:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=ZStppNYGYgo:RkdexS7rKMU:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=qj6IDK7rITs" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=ZStppNYGYgo:RkdexS7rKMU:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=ZStppNYGYgo:RkdexS7rKMU:gIN9vFwOqvQ" border="0"></img></a> </div>2011-02-25T00:00:00Zhttp://perltraining.com.au/tips/2011-02-15.html<h2>Experimenting with new versions of Perl and modules</h2> <p>Many developers have a chicken-and-egg problem when it comes to upgrading their version of Perl. On one hand, the system version of Perl cannot be upgraded because it might break existing scripts, on the the other hand it has been difficult to install your own version of Perl to see whether an upgrade is safe. The same happens with modules.</p> <p><b><a href="http://perltraining.com.au/tips/2011-02-15.html">Read more...</a></b></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=gBsUU0tQGmQ:hJ61c79sMBU:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=gBsUU0tQGmQ:hJ61c79sMBU:F7zBnMyn0Lo"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=gBsUU0tQGmQ:hJ61c79sMBU:F7zBnMyn0Lo" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=gBsUU0tQGmQ:hJ61c79sMBU:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=gBsUU0tQGmQ:hJ61c79sMBU:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=gBsUU0tQGmQ:hJ61c79sMBU:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/PerlTips?d=qj6IDK7rITs" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/PerlTips?a=gBsUU0tQGmQ:hJ61c79sMBU:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/PerlTips?i=gBsUU0tQGmQ:hJ61c79sMBU:gIN9vFwOqvQ" border="0"></img></a> </div>2011-02-15T00:00:00Z
