NAME

Module::List::Wildcard - A fork of Module::List that groks wildcard

VERSION

This document describes version 0.004009 of Module::List::Wildcard (from Perl distribution Module-List-Wildcard), released on 2021-01-16.

SYNOPSIS

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

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

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

Wildcard support:

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

all option:

$modules = list_modules("Module::", { list_modules => 1, all => 1});

DESCRIPTION

This module is a fork of Module::List. It's exactly like Module::List 0.004, except for the following differences:

• lower startup overhead (with some caveats)

  It strips the usage of Exporter, 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 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 (sets recurse option to 1).

  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,
  }

Module::List

Module::List::Tiny

Module::List::More, from which Module::List::Wildcard is actually forked from. Module::List::More contains more features, including wildcard support. I'm currently maintainng both modules. Eventually this duplication might be resolved in the future.
