<p>Updated <a href="/howto/perl/life-with-cpan/non-root/">Using CPAN with a non-root account</a> to include better details on testing a custom <tt>PERL5LIB</tt>, among other improvements. On a related note, ZSH functions to show the version of or path to a named Perl module:</p> <p class="sial-block-code">function pm-version { perl -M$1 -le "print \$$1::VERSION" } function pm-path { perl -M$1 -le "print \$INC{\"${1//::/\/}.pm\"}" }</p> <p>Some modules, however, may not set a <tt>$VERSION</tt> scalar, and instead might offer a <tt>version</tt> method, or something else entirely. Regardless of this complication, the functions offer a quick mechanism to check the version, path to the module, and means to inspect the code:</p> <p class="sial-block-shell">$ <kbd>pm-version Bundle::LWP</kbd> 5.810 $ <kbd>pm-path !$</kbd> pm-path Bundle::LWP /home/jmates/lib/perl5/Bundle/LWP.pm $ <kbd>less `!!`</kbd> …</p> <!-- technorati tags start --><p style="text-align:right;font-size:10px;">Technorati Tags: <a href="http://www.technorati.com/tag/Perl" rel="tag">Perl</a>, <a href="http://www.technorati.com/tag/Unix" rel="tag">Unix</a></p><!-- technorati tags end --> <br /> 2009-03-02T01:31:40-0800 337
