may not be the prettiest w/ the nested maps, but this works for any number of tiers .. it converts the "1.10.4" to "00001.00010.00004" and sorts that, which will sort properly, and then converts back to strip the leading zeros. (Note the caveat that the '%05d' might need to be '%08d' or something.)
use strict; use warnings; my @s = ( "1.0", "1.10", "1.2", "3", "2.0.1", "4.1.1.1", "1.0.1", "1.1 +", "1.0.2", "2.0" ); my @t = map { join ".", map { sprintf '%d', $_ } split(/\./,$_) } sort map { join ".", map { sprintf '%05d', $_ } split(/\./,$_) } @s; print "IN: ", join(" ", @s), "\n"; print "OUT: ", join(" ", @t), "\n"; __END__ IN: 1.0 1.10 1.2 3 2.0.1 4.1.1.1 1.0.1 1.1 1.0.2 2.0 OUT: 1.0 1.0.1 1.0.2 1.1 1.2 1.10 2.0 2.0.1 3 4.1.1.1

Title:
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.
