Module::Install::Admin(3pm) User Contributed Perl Documentation Module::Install::Admin(3pm)


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


In a Module::Install extension module:

    sub extension_method {
        my $self = shift;

As an one-liner:

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

The two snippets above are really shorthands for


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.


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 "COOKBOOK / EXAMPLES" in Module::Install instead.


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/ 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/ if the current file is somewhere else. This ensures that the included version of inc/Module/ 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/.
