Parse::CPAN::Meta is a parser for META.json and META.yml files, using JSON::PP and/or CPAN::Meta::YAML.

This module provides a general-purpose clone function to make deep copies of Perl data structures. It calls itself recursively to copy nested hash, array, scalar and reference types, including tied variables and objects.

This Perl module provides Chinese encodings that are not part of Perl by default, including "BIG5-1984", "BIG5-2003", "BIG5PLUS", "BIG5EXT", "CCCII", "EUC-TW", "CNS11643-*", "GB18030", and "UNISYS".

Sub::Quote provides an efficient generation of subroutines via string eval.

This module provides functions to encode and decode UTF-8 encoding form as specified by Unicode and ISO/IEC 10646:2011.

Many Perl distributions use a Build.PL file instead of a Makefile.PL file to drive distribution configuration, build, test and installation. Traditionally, Build.PL uses Module::Build as the underlying build system. This module provides a simple, lightweight, drop-in replacement. Whereas Module::Build has over 6,700 lines of code; this module has less than 120, yet supports the features needed by most distributions.

Text::Haml implements Haml http://haml.info/docs/yardoc/file.REFERENCE.html specification.

Test::Count is a set of perl modules for keeping track of the number of tests in a test file. It includes the ability to use mathematical expressions and variables when computing the count.

This module is a helper for easily finding configuration file locations. This information can be used to find a suitable place for installing configuration files or for finding any piece of settings.

This module is able to generically format rows of data into tables.

Config::INI::Reader::Ordered is a Perl library for parsing .ini files that returns the sections in order.

This package provides a way to have readable configuration files outside your Perl script. Configurations can be imported, sections can be grouped, and settings can be accessed from a tied hash.

Mouse is a Moose compatible object system that implements a subset of the functionality for reduced startup time.

This module brings the speed advantages of Set::IntSpan (written by Steven McDougall) to arrays. Uses include manipulating grades, routing tables, or any other situation where you have mutually exclusive ranges of integers that map to given values.

Hook::LexWrap allows you to install a pre- or post-wrapper (or both) around an existing subroutine. Unlike other modules that provide this capacity (e.g., Hook::PreAndPost and Hook::WrapSub), Hook::LexWrap implements wrappers in such a way that the standard caller function works correctly within the wrapped subroutine.

This module provides a flexible calling interface to some frequently-performed string conversion functions, including applying and expanding standard C/Unix-style backslash escapes like and , wrapping and removing double-quotes, and truncating to fit within a desired length.

File::Find::Rule::Perl provides methods for finding various types Perl-related files, or replicating search queries run on a distribution in various parts of the CPAN ecosystem.

This module provides a small, fast utility for working with file paths.

This class is the base class for all time zone objects. A time zone is represented internally as a set of observances, each of which describes the offset from GMT for a given time period. Note that without the DateTime module, this module does not do much. It's primary interface is through a DateTime object, and most users will not need to directly use DateTime::TimeZone methods.

lib::relative module proposes a more straightforward method than adding a path to @INC: take a path relative to the current file, absolutize it, and add it to @INC.

Chaolin Zhang's Perl Library (czplib) contains assorted functions and data structures for processing and analysing genomic and bioinformatics data.

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

This module tries to find middle ground between one at a time and all at once processing of data sets. The purpose of this module is to avoid the overhead of implementing an iterative api when this isn't necessary, without breaking forward compatibility in case that becomes necessary later on.

This module is an alternative to String::Trim. Instead of a single trim function, this module provides several from which you can choose on, depending on your needs.
