NAME

PERLANCAR::Module::List - A fork of Module::List

VERSION

This document describes version 0.004005 of PERLANCAR::Module::List (from Perl distribution PERLANCAR-Module-List), released on 2019-09-12.

SYNOPSIS

Use like you would Module::List, e.g.:

use PERLANCAR::Module::List qw(list_modules);

$id_modules = list_modules("Data::ID::", { list_modules => 1});
$prefixes = list_modules("", { list_prefixes => 1, recurse => 1 });

DESCRIPTION

This module is my personal experimental fork of Module::List; the experiment has also produced other forks like Module::List::Tiny, Module::List::Wildcard. It's like Module::List, except for the following differences:

• lower startup overhead (with some caveats)

  It avoids using Exporter and implements its own import(). It avoids IO::Dir, Carp, File::Spec, with the goal of saving a few milliseconds (a casual test on my PC results in 11ms vs 39ms).

  Path separator is hard-coded as /.

• Recognize all option

  If set to true and return_path is also set to true, will return all found paths for each module instead of just the first found one. The values of result will be an arrayref containing all found paths.

• Recognize wildcard option

  This boolean option can be set to true to recognize wildcard pattern in prefix. Wildcard patterns such as jokers (?, *, **), classes ([a-z]), as well as braces ({One,Two}) are supported. ** implies recursive listing.

  Examples:

  list_modules("Module::P*", {wildcard=>1, list_modules=>1});

  results in something like:

  {
      "Module::Patch"             => undef,
      "Module::Path"              => undef,
      "Module::Pluggable"         => undef,
  }

  while:

  list_modules("Module::P**", {wildcard=>1, list_modules=>1});

  results in something like:

  {
      "Module::Patch"             => undef,
      "Module::Path"              => undef,
      "Module::Path::More"        => undef,
      "Module::Pluggable"         => undef,
      "Module::Pluggable::Object" => undef,
  }

  while:

  list_modules("Module::**le", {wildcard=>1, list_modules=>1});

  results in something like:

  {
      "Module::Depakable"                => undef,
      "Module::Install::Admin::Bundle"   => undef,
      "Module::Install::Admin::Makefile" => undef,
      "Module::Install::Bundle"          => undef,
      "Module::Install::Makefile"        => undef,
      "Module::Pluggable"                => undef,
  }
