( #3333=superdoc: print w/replies, xml ) Need Help??
Another solution that works with letter ranges as well, without using any regexes:

#!/usr/bin/perl -w use strict; sub human { my (@r, $g, $s, $l); while (@_) { $l = $g = $s = shift; $l = shift while (++$g eq ($_[0] || '')); push(@r, $s eq $l ? $s : "$s-$l"); } @r; } print join(", ", human(1..12, 14..21, 'aa'..'af', 'zz'..'aaf')), "\n"; print join(", ", human(1, 2, 3, 5, 7, 8, 9, 11, 14)), "\n";

Output is:

1-12, 14-21, aa-af, zz-aaf 1-3, 5, 7-9, 11, 14

update: made work with solo items (thanks CharlesClarkson!)

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

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
