Re^5: Dynamic option

[JavaFan]

As the author of Getopt::Long always says, options are optional, or they wouldn't be options. So the "they may or may not be present" isn't anything special. In fact, it's the bread and butter of Getopt::Long - it only deals with things that may or may not be present.

If you make the call syntax like:

findfiles --input data modem apps --nd --na --nc --des "..." -r 1000

Something like:

GetOptions 'input=s{0,}'  =>  \my @input,
           'na'           =>  \my $na,
           'nd'           =>  \my $nd,
           'nc'           =>  \my $nc,
           'des=s'        =>  \my $des,
           'r=i'          =>  \my $r;

Should do the trick.

That's not what the OP wants. He wants to be able to specify 'nd' for -input (or not), and again for data (or not).

Your solution only permits specifying it once (although it could be changed to counted), and it's not associated with "input" or "data".
