NAME
Module::Used - Find modules loaded by Perl code without running it.
VERSION
This document describes Module::Used version 1.3.0.
SYNOPSIS
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 >;' );DESCRIPTION
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.
Dynamically loaded modules will not be found.
INTERFACE
