Command line args in Perl



  • Here here at X10 we pride ourselves on top notch coding.  (snicker)  So I thought I would make sure that you all understood the most effective way of parsing command line arguments in Perl (per a previous perl developer)...

     

    #Cycle through the command line arguments

    @ARGV = ('-') unless @ARGV;

    while ( $ARGV = shift )
    {

            push @data, $ARGV;
    }

    #Get the data from the command line

    foreach $item (@data)
    {
            chomp $item;

            if($file eq "")
            {
                    if($item =~ /settings.dat/)
                    {
                            $file = $item;
                    }
            }
            elsif($search_key eq "")
            {
                    $search_key = $item;
            }
            elsif($deal eq "")
            {
                    $deal = $item;
            }
    }

    #Make sure we have the data before we continue

    if(($file eq "")||($search_key eq "")||($deal eq ""))
    {
            exit(0);
    }



  •  that is amazingly shitty.



  •  Isn't GetOpt::Long a standard module? Sheesh.



  • I wonder what is the first loop for.
