Here's another variation on the same theme. In this case a new array is created from @ARGV with multiple words collapsed into one array element. The advantage is that this rebuilt version of @ARGV can be fed into Getopt::Long's GetOptionsFromArray method:
use strict; use warnings; use Getopt::Long qw(GetOptionsFromArray); my @arglist = (); for my $arg (@ARGV) { if ($arg =~ /^-/) { push(@arglist, $arg); } else { if ($arglist[$#arglist] =~ /^-/) { push(@arglist, $arg); } else { $arglist[$#arglist] .= ' '.$arg; } } } my ($opta, $optb, $optc); GetOptionsFromArray(\@arglist, 'a=s' => \$opta, 'b=s' => \$optb, 'c=s' => \$optc); for ($opta, $optb, $optc) { print $_,"\n"; }

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.
