Module::Used - Find modules loaded by Perl code without running it.
This document describes Module::Used version 1.3.0.
use Module::Used qw< :all >; @modules = modules_used_in_files(@files); @modules = modules_used_in_modules(@module_names); # "strict", "Find::Bin", "warnings" @modules = modules_used_in_string( 'use strict; require Find::Bin; no warnings;' ); # "Exporter" @modules = modules_used_in_string( 'use parent 0.221 qw< Exporter >;' );
Modules are found statically based upon use and require statements. If use of the base or parent is found, both that module and the referenced ones will be returned. If Moose or Moose::Role are found, this will look for extends and with sugar will be looked for; presently, this will miss modules listed in parentheses.
