NAME

6       Module::Used - Find modules loaded by Perl code without running it.
7

VERSION

9       This document describes Module::Used version 1.3.0.
10

SYNOPSIS

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

DESCRIPTION

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

INTERFACE

35       Nothing is exported by default, but you can import everything using the
36       ":all" tag.
37
38       " modules_used_in_files( @files ) "
39           Return a list of modules used in the specified files.
40
41           "die"s if there is a problem reading a file.
42
43       " modules_used_in_modules( @module_names ) "
44           Return a list of modules used in the specified modules.
45
46           "die"s if there any of the modules weren't found in @INC.
47
48       " modules_used_in_string( $string ) "
49           Return a list of modules used in the code in the parameter.
50
51       " modules_used_in_document( $document ) "
52           Return a list of modules used in the specified PPI::Document.

DIAGNOSTICS

55       Could not find module "%s" in @INC.
56           Cannot find the location of the named module.  Note that this
57           module will not find any dynamically loaded modules.
58
59       "%s" does not exist.
60           Cannot find the file.
61
62       "%s" is not readable.
63           Cannot read the file.
64
65       "%s" is a directory.
66           The "file" was actually a directory.
67
68       Could not parse "%s".
69           PPI could not interpret the file as a Perl document.
