Package::Util::Lite(3) User Contributed Perl Documentation Package::Util::Lite(3)

Package::Util::Lite - Package-related utilities

This document describes version 0.001 of Package::Util::Lite (from Perl distribution Package-Util-Lite), released on 2019-01-06.

 use Package::Util::Lite qw(
     package_exists
     list_subpackages
 );

 print "Package Foo::Bar exists" if package_exists("Foo::Bar");

 my @subpkg    = list_subpackages("Foo::Bar");
 my @allsubpkg = list_subpackages("Foo::Bar", 1); # recursive

This module provides package-related utilities. You should check Package::Stash first, then here.

Usage:

 package_exists($name) => bool

Return true if package "exists". By "exists", it means that the package has been defined by "package" statement or some entries have been created in the symbol table (e.g. "$Foo::var = 1;" will make the "Foo" package "exist").

This function can be used e.g. for checking before aliasing one package to another. Or to casually check whether a module has been loaded.

List subpackages, e.g.:

 (
     "Foo::Bar::Baz",
     "Foo::Bar::Qux",
     ...
 )

If $recursive is true, will also list subpackages of subpackages, and so on.
