9 This document describes Module::Used version 1.3.0.
10
12 use Module::Used qw< :all >;
13
14 @modules = modules_used_in_files(@files);
15 @modules = modules_used_in_modules(@module_names);
16
17 # "strict", "Find::Bin", "warnings"
18 @modules = modules_used_in_string(
19 'use strict; require Find::Bin; no warnings;'
20 );
21
22 # "Exporter"
23 @modules = modules_used_in_string( 'use parent 0.221 qw< Exporter >;' );
24
26 Modules are found statically based upon "use" and "require" statements.
27 If use of the base or parent is found, both that module and the
28 referenced ones will be returned. If Moose or Moose::Role are found,
29 this will look for "extends" and "with" sugar will be looked for;
30 presently, this will miss modules listed in parentheses.
31
32 Dynamically loaded modules will not be found.
33
35 Nothing is exported by default, but you can import everything using the
36 ":all" tag.
