Hi,
I have to write several perl scripts with a number of modules included. Therefore, I have to type many "use" statements at the top of each script. Is there a way to dump all these "use" statements in a different file and then just include that file everytime I have to include these "use" statements?
I know that writing a module is a great way to do something like that, but doesn't a module export variables and subroutines? How can I make a module export "use" statements?
Perl has three distinct ways of separating content: modules, packages, and objects. Modules do not export variables and subroutines; packages do. Or to be specific, packages can export variables and subroutines to the main package.
You can use a module as a straight-forward include. Simply list the material you want and it will be including in the package where the 'use' command is.
In the main file:
use MyUseList;
Create a file called MyUseList.pm and add your list.
#!/usr/bin/perl
use strict; use warnings;
# Your list goes here
1; # Modules must return a non-false value __END__
