How can I reuse some functions in a Perl script?

Question

I am facing a problem that require the reuse some of the functions within another Perl script. I am writing some test scripts. The test scripts are basically build on each other.

Say Script 1 does:

Some code to prepare the test. A. B. C. Some code to determine the success.

Then Script 2 does:

Some code to prepare the test. A. B. C. D. E. Some code to determine the success.

How can I reuse A.B.C of script 1 in script 2?

Calling script 1 from script 2 will not work because of the code to determine the success of the script. What is the best way to do this?

Thanks

Answer 1

Put the functions in a module and include that from both files.

See http://perldoc.perl.org/perlmod.html for more info.

Answer 2

Foo/Common.pm:

package Foo::Common;
use strict;
use warnings;
use parent 'Exporter';
our @EXPORT_OKAY = qw(frob borf);

sub frob {}
sub borf {}

1;

In some script or module, give or take a use lib to get Foo/Common.pm in @INC:

use Foo::Common qw(frob borf);
frob();
