exported-constants
A Perl module for constants modules
SYNOPSIS
package MyProg::Constants;
use exported::constants
USER_TYPE_USER => 'U',
USER_TYPE_APPLICATION => 'A',
USER_TYPE_ROBOT => 'B',
;
package MyProg::App;
use MyProg::Constants;
my @real_users = $users->search({ user_type => USER_TYPE_USER, });
DESCRIPTION
This is a boilerplate-removal module for creating modules of just constants in your program. This is useful if you have a lot of magic numbers you want to eliminate, especially things that show up in database schemas or APIs that you want to re-use across multiple modules.
It's pretty simple to use; just say
use exported::constants
CONSTANT1 => $value1,
CONSTANT2 => $value2,
;
and your package is automatically an exporter, and automatically exports (by default) all the constants listed.
