NAME Package::Util::Lite - Package-related utilities VERSION This document describes version 0.001 of Package::Util::Lite (from Perl distribution Package-Util-Lite), released on 2019-01-06. SYNOPSIS 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 DESCRIPTION This module provides package-related utilities. You should check Package::Stash first, then here. FUNCTIONS package_exists 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($name[, $recursive]) => @res List subpackages, e.g.: ( "Foo::Bar::Baz", "Foo::Bar::Qux", ... ) If $recursive is true, will also list subpackages of subpackages, and so on.
