Perl functions Deepan - M.Sc(SE) - 03MW06 03-06-2008

 Hi all,
I am using a file abc.pl which is having a function called
get().

I am including this perl file inside a cgi script, and also i am
calling this function inside this script. Now this function residing
inside the perl file abc.pl should now look into the URL of the
calling CGI script and it should return the URL for the cgi script.

Can any of you help me to solve this?

Thanks,
Deepan

 Hi,

You need to make a package
something like this

abc.pm
package abc;
use strict;
use warnings;

sub get {
}

and then in your script;

use abc;
.
.
.
.
abc::get(blablabla);

I did not really understand what you want to make but maybe the module
CGI has s function which performs what you need.

Best regards,
David

use CGI;

sub get {
return CGI->new->self_url;
}

What method are you using for doing the including? Shouldn't this be
abc.pm rather than abc.pl?

Why? Your CGI script is "in charge". Shouldn't it send abc.pl what it
needs, rather than expecting abc.pl to dig up what it needs on its own? It
seems that you are aiming for the worst of both worlds--you want code
scattered over multiple files, but without having modular designs that
makes the files loosely coupled.
