| Subject: | Not able to restrict the number of arguments for an option with GetOptions in Getopt::Long |
use strict;
use warnings;
use Getopt::Long;
my @letters;
my @words;
GetOptions(
"letters=s{2}" => \@letters,
"words=s{,}" => \@words
);
print "Letters: " . join(", ", @letters) . "\n";
print "Words: " . join(", ", @words) . "\n";
When I run this program I get the output as follows:
perl getopts.pl --letters a --words he she it
Letters: a, --words
Words:
--words is read as part of --letters arguments itself. I expect
GetOptions to throw error message in this scenario. How to get this done.
FYI....
