( #3333=superdoc: print w/replies, xml ) Need Help??

Like it or not, modules are the best way. Modules need not be difficult; you probably need only a small fraction of the many options available to a module author. To get started, see tachyon's Simple Module Tutorial, including the other monks' comments at the bottom. If the tutorial is too simple, try perlman:perlmod. If too complex, try my skeleton code below. I have pared it down to the bare essentials for illustration only; it runs correctly, but is missing the seat-belts (use strict) and air-bags (use warnings), so don't take it out of the parking lot!

Use h2xs -n Common_Code -AX to generate a real module template once you are more comfortable with how a module works.

# this is in file package Common_Code; sub log_debug_message { print "DEBUG: I see ", join(", ", @_), ".\n"; } 1;
Here's a script which uses it:
#!/usr/bin/perl use Common_Code; my( $a1, $b2, $c3 ) = qw( red blue green ); Common_Code::log_debug_message( $a1, $b2, $c3 );
The output:
DEBUG: I see red, blue, green.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;

      Should cpanminus be part of the standard Perl release?
