Module::Build::XSUtil is subclass of Module::Build for support building XS modules.

This is a list of a new parameters in the Module::Build::new method:

1. needs_compiler_c99: This option checks C99 compiler availability.

2. needs_compiler_cpp: This option checks C++ compiler availability. Can also pass extra_compiler_flags and extra_linker_flags for C++.

3. generate_ppport_h: Generate ppport.h by Devel::PPPort.

4. generate_xshelper_h: Generate xshelper.h which is a helper header file to include EXTERN.h, perl.h, XSUB.h and ppport.h, and defines some portability stuff which are not supported by ppport.h.

   It is ported from Module::Install::XSUtil.

5. cc_warnings: Toggle compiler warnings. Enabled by default.

6. -g options: Invoke Build.PL with -g to enable debug options.

Meta::Builder is designed to be a generic tool for writing Meta objects. Unlike specialized tools, Meta::Builder makes no assumptions about what metrics you will care about. Meta::Builder also makes it simple for others to extend your meta-object based tools by providing hooks for other packages to add metrics to your meta object.

File::HomeDir is a module for locating the directories that are owned by a user (typically your user) and to solve the various issues that arise trying to find them consistently across a wide variety of platforms.

This module provides bare bones try/catch/finally statements that are designed to minimize common mistakes with eval blocks, and nothing else.

IO::String is an IO::File (and IO::Handle) compatible class that reads or writes data from in-core strings.

Exporter::Declare is a meta-driven exporting tool. It tries to adopt all the good features of other exporting tools, while replacing bad interfaces. Exporter::Declare also provides hooks that allow you to add options and arguments for import. Exporter::Declare's meta-driven system allows for top-notch introspection.

This module provides tools to deal with International Standard Music Numbers.

This module provides tools to deal with International Standard Serial Numbers.

This module first checks to see if either Cpanel::JSON::XS or JSON::XS is already loaded, in which case it uses that module. Otherwise it tries to load Cpanel::JSON::XS, then JSON::XS, then JSON::PP in order, and either uses the first module it finds or throws an error.

The "mro" namespace provides several utilities for dealing with method resolution order and method caching in general in Perl 5.9.5 and higher. This module provides those interfaces for earlier versions of Perl (back to 5.6.0).

Stream::Buffered is a buffer class to store arbitrary length of byte strings and then get a seekable filehandle once everything is buffered. It uses PerlIO and/or temporary file to save the buffer depending on the length of the size.

This module implements a Singleton class from which other classes can be derived. By itself, the Class::Singleton module does very little other than manage the instantiation of a single object.

JSON::Parse is a module for parsing JSON. It offers parse_json which takes a string containing JSON and returns an equivalent Perl structure, valid_json which returns true or false depending on whether the JSON is correct or not, assert_valid_json which produces a descriptive fatal error if the JSON is invalid, and so on.

Devel::Cycle This is a tool for finding circular references in objects and other types of references. Because of Perl's reference-count based memory management, circular references will cause memory leaks.

This module provides functions for fast reading and writing of files.

File::ShareDir::Dist finds share directories for distributions. It is a companion module to File::ShareDir.

The DateTime::Locale modules provide localization data for the DateTime.pm class.

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

The package provides a number of useful typemaps as submodules of ExtUtils::Typemaps.

This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at https://www.w3.org/TR/NOTE-datetime. This format is the native date format of RSS 1.0. It can be used to parse these formats in order to create the appropriate objects.

MooseX::Role::WithOverloading allows you to write a Moose::Role which defines overloaded operators and allows those overload methods to be composed into the classes/roles/instances it's compiled to, where plain Moose::Roles would lose the overloading.

File::Next is a Perl CPAN module for finding files.

Crypt::UnixCrypt_XS implements the DES-based Unix crypt function. For those who need to construct non-standard variants of crypt, the various building blocks used in crypt are also supplied separately.

This package provides an ASCII mapping for the eucJP encoding.
