Space in getopt option value

[Anonymous Monk]

Dear Monks,

I seek to find a way for getopt to accept a option value with spaces, e.g.

myhack.pl --foo='bar1 bar2 bar3'

Your's humbly, /Mats

Here is one way:

use warnings;
use strict;
use Getopt::Long;
use Data::Dumper;
$Data::Dumper::Sortkeys=1;

my %opt;
GetOptions(\%opt, 'foo=s') or die;
print Dumper(\%opt);

__END__


myhack.pl --foo 'bar1 bar2 bar3'

$VAR1 = {
          'foo' => 'bar1 bar2 bar3'
        };

The you can process $opt{foo} if you wish.

Are you passing multiple values to the --foo argument or one string value with spaces? If the former, you can use something like this:

myhack.pl --foo bar1 --foo bar2 --foo bar3

Be sure to change GetOptions ("foo=s" => \$foo); to GetOptions ("foo=s" => \@foo);

What operating system and or shell are you using?

Getopt parses from @ARGV, and how @ARGV gets populated depends on your shell

On windows cmd.exe

$ perl -MData::Dump -e " dd\@ARGV "  -- --foo='bar1 bar2 bar3'
["--foo='bar1", "bar2", "bar3'"]

This is correct, as ' is not a quoting character on cmd.exe -- you have to quote according to your shell -- more on this in perlrun, Behind the GUI lives the Shell and How Command Line Parameters Are Parsed
