module::optional
Module::Optional(3pm) User Contributed Perl Documentation Module::Optional(3pm)
NAME
Module::Optional - Breaking module dependency chains
SYNOPSIS
use Bar::Dummy qw();
use Module::Optional Bar;
ABSTRACT
This module provides a way of using a module which may or may not be installed on the target machine. If the module is available it behaves
as a straight use. If the module is not available, subs are repointed to their equivalents in a dummy namespace.
DESCRIPTION
Suppose you are the developer of module "Foo", which uses functionality from the highly controversial module "Bar". You actually quite like
"Bar", and want to reuse its functionality in your "Foo" module. But, many people will refuse to install "Foo" as it needs "Bar". Maybe
"Bar" is failing tests or is misbehaving on some platforms.
Making "Bar" an optional module will allow users to run "Foo" that don't have "Bar" installed. For Module::Build users, this involves
changing the status of the "Bar" dependency from "requires" to "recommends".
To use this module, you need to set up a namespace "Bar::Dummy". The recommended way of doing this is to ship lib/Bar/Dummy.pm with your
module. This could be shipped as a standalone module. A dummy module for "Params::Validate" is shipped with Module::Optional, as this was
the original motivation for the module. If there are other common candidates for dummying, petition me, and I'll include them in the
Module::Optional distribution.
Using an optional module
Place the lines of code in the following order:
use Bar::Dummy qw();
use Module::Optional qw(Bar quux wibble wobble);
Always set up the dummy module first, but don't import anything - this is to avoid warnings about redefined subroutines if the real Bar is
installed on the target machine. Module::Optional will do the importing: quux wibble and wobble from the real Bar if it exists, or from
Bar::Dummy if it doesn't.
Asking for a module version
If you need a version of the module or later, this can be done thus:
use Bar::Dummy qw();
use Module::Optional qw(Bar 0.07 quux wibble wobble);
If version 0.07 or later of Bar is not available, the dummy is used.
Suppressing the module
You will probably be developing your module on a platform that does have Bar installed (I hope). However, you need to be able to tell what
happens on systems without Bar. To do this, run the following (example is Unix):
MODULE_OPTIONAL_SKIP=1 make test
You also want to do this in tests for the dummy module that you are providing. (You are providing tests for this module?) This can easily
be done with a begin block at the top of the test:
BEGIN {
local $ENV{MODULE_OPTIONAL_SKIP} = 1;
use Module::Optional qw(Params::Validate);
}
Writing a ::Dummy Module
You provide a namespace suffixed with ::Dummy containing subs corresponding to all the subs and method calls for the optional module. You
should also provide the same exports as the module itself performs.
Adhere strictly to any prototypes in the optional module.
An example of a dummy module is Params::Validate::Dummy, provided in this distribution.
INTERNALS
Module::Optional performs two types of redirection for the missing module. Firstly via @ISA inheritance - Foo::Bar inherits from
Foo::Bar::Dummy.
Secondly, an AUTOLOAD method is added to Foo::Bar, which will catch calls to subs in this namespace.
