NAME

Module::Install::Admin - Author-side manager for Module::Install

SYNOPSIS

In a Module::Install extension module:

sub extension_method {
    my $self = shift;
    $self->admin->some_method(@args);
}

As an one-liner:

% perl -MModule::Install::Admin -e'&some_method(@args);'

The two snippets above are really shorthands for

$some_obj->some_method(@args)

where $some_obj is the singleton object of a class under the Module::Install::Admin::* namespace that provides the method some_method. See "METHODS" for a list of built-in methods.

DESCRIPTION

This module implements the internal mechanism for initializing, including and managing extensions, and should only be of interest to extension developers; it is never included under a distribution's inc/ directory, nor are any of the Module::Install::Admin::* extensions.

For normal usage of Module::Install, please see Module::Install and Module::Install-Cookbook instead.

Bootstrapping

When someone runs a Makefile.PL that has use inc::Module::Install, and there is no inc/ in the current directory, Module::Install will load this module bootstrap itself, through the steps below:

  • First, Module/Install.pm is POD-stripped and copied from @INC to inc/. This should only happen on the author's side, never on the end-user side.

  • Reload inc/Module/Install.pm if the current file is somewhere else. This ensures that the included version of inc/Module/Install.pm is always preferred over the installed version.

  • Look at inc/Module/Install/*.pm and load all of them.

  • Set up a main::AUTOLOAD function to delegate missing function calls to Module::Install::Admin::load -- again, this should only happen at the author's side.

  • Provide a Module::Install::purge_self function for removing included files under inc/.
