in thread Wisdom on the Getopt::Long module

Well,

Incase -x option was not entered i want the value to be undef or '' or 0.

Incase -x was entered with no string, i want the value to be 1.

Incase -x was entered with the string, i want the value to be set to the string.

The first n last happen, but its the 2nd one i want to happen. I dont think what u posted will work.

    Why did you ignore the hint to avoid <pre>-Tags around your post?

    Did you only think about the given code, or did you try it?

    You also could have a look at Getopt::Long, which explains what happens, if an option doesn't have its optional argument...

    Another possibility is something like this:

    #! /usr/bin/perl # vim:ts=4 sw=4 sts=4 et nu fdc=3: use strict; use warnings; use Getopt::Long; my $x = "unset"; GetOptions( 'x:s' => sub { $x = $_[1] ? $_[1] : 'true' }, ) or exit 255; print "$x\n";

    It's up to you to refine the checks and values to fit your needs.

    added:

    $ perl /tmp/getopt.pl unset $ perl /tmp/getopt.pl -x true $ perl /tmp/getopt.pl -x foo foo
      Why did you ignore the hint to avoid pre Tags around your post?

      Cause i never saw it. Until after i posted. For some reason i didnt notice the scroll bar

      Did you only think about the given code, or did you try it?

      I did try and it didnt work! I think ur stuck on my words, just cause i said "i think it doesnt work". It looked like he tried and it worked for him, n not for me. I have explained myself enough.

      And for your solution. I thank you!
