I use a hash for the options whose keys are option letters and whose values can be either a scalar for a single or empty value or an array reference for multiple values, e.g.:
use Getopt::Std; my %opt; getopt('abc',\%opt); Multivalued(\%opt); #... sub Multivalued { # convert lists to array refs. my $href = shift; while( my ($k, $v ) = each %$href ) { my @anon = split /\,/, $v or next; $href -> { $k } = \@anon; } }
And to iterate the combinations of the arrays, see Math::Combinatorics.

Update: and if you have to support protected commas in quotes, instead of just splitting, parse with something like Text::Csv::Simple


^M Free your mind!

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 or How to display code and escape characters are good places to start.
