( [id://3333]=superdoc: print w/replies, xml ) Need Help??
After recommending the Schwartzian Transform to someone recently (and directing them to http://www.5sigma.com/perl/schwtr.html as a reference) I meditated that someone has probably written a module to encapsulate the Schwartzian Transform. I looked but couldn't see one.

I was thinking of something like:

$file_size_sort = new Sort::Schwartzian left => '-s $a', op=>'<=>', right =>'-s $b';
... later ...

@sorted = $file_size_sort->(@files);
or
$sort_by_score = new Sort::Schwartzian left => '$b->score', op=>'<=>', right =>'$a->score';
etc.

If such a thing doesn't exist I'm suggesting someone write one. Volunteers?

Use:  <p> text here (a paragraph) </p>

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.
