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").
package
$Foo::var = 1;
Foo
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.
