XString provides the B string helpers in one isolated package. Right now only cstring and perlstring are available.

The YAML.pm module implements a YAML Loader and Dumper based on the YAML 1.0 specification.

Mail::Sendmail is a pure perl module that provides a simple means to send email from a perl script. The module only requires Perl5 and a network connection.

File::Slurp provides subroutines to read or write entire files with a simple call. It also has a subroutine for reading the list of file names in a directory.

Data::SExpression parses Lisp S-Expressions into Perl data structures.

This module provides configure time utilities for using C headers, libraries, or OS features.

Writing exporters is a pain. Some use Exporter, some use Sub::Exporter, some use Moose::Exporter, some use Exporter::Declare ... and some things are pragmas. Exporting on someone else's behalf is harder. The exporters don't provide a consistent API for this, and pragmas need to have their import method called directly, since they effect the current unit of compilation. Import::Into provides global methods to make this painless.

Sys::CPU is a module for counting the number of CPUs on a system, and determining their type and clock speed.

Text::CSV provides facilities for the composition and decomposition of comma-separated values. An instance of the Text::CSV class can combine fields into a CSV string and parse a CSV string into fields.

This package provides a package to change terminal modes and perform non-blocking reads.

This module implements the Rijndael cipher which has been selected as the Advanced Encryption Standard. The keysize for Rijndael is 32 bytes. The blocksize is 16 bytes (128 bits). The supported encryption modes are:

• MODE_CBC---Cipher Block Chaining

• MODE_CFB---Cipher feedback

• MODE_CTR---Counter mode

• MODE_ECB---Electronic cookbook mode

• MODE_OFB---Output feedback

This package is a companion module to DateTime.pm. It implements the Julian calendar. It supports everything that DateTime.pm supports and more: about one day per century more, to be precise.

This Perl module implements Perl hashes that preserve the order in which the hash elements were added. The order is not affected when values corresponding to existing keys in the IxHash are changed. The elements can also be set to any arbitrary supplied order. The familiar perl array operations can also be performed on the IxHash.

Devel::Caller provides meatier version of caller.

This module is for manipulating data as hierarchical tag/value pairs (Structured TAGs or Simple Tree AGgregates). These datastructures can be represented as nested arrays, which have the advantage of being native to Perl.

Data::Float is about the native floating point numerical data type. A floating point number is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native floating point type, classification functions and functions to manipulate floating point values at a low level.

This module implements Spreadsheet::XLSX parsing Microsoft Excel 2007 xlsx files.

This module is for reading record-oriented data in a delimited text file. The most common example have records separated by newlines and fields separated by commas or tabs, but this module aims to provide a consistent interface for handling sequential records in a file however they may be delimited.

DateTime::Format::Builder creates DateTime parsers. Many string formats of dates and times are simple and just require a basic regular expression to extract the relevant information. Builder provides a simple way to do this without writing reams of structural code.

This module facilitates using Moose or Mouse modules without changing the code. By default, Mouse will be provided to libraries, unless Moose is already loaded, or explicitly requested by the end-user. End users can force the decision of which backend to use by setting the environment variable ANY_MOOSE to be Moose or Mouse.

App::Nopaste provides easy access to any pastebin.

This package implements usleep, ualarm, and gettimeofday for Perl, as well as wrappers to implement time, sleep, and alarm that know about non-integral seconds.

PerlIO::utf8_strict provides a fast and correct UTF-8 PerlIO layer. Unlike Perl's default :utf8 layer it checks the input for correctness.

IO::Pty provides an interface to allow the creation of a pseudo tty. IO::Pty inherits from IO::Handle and so provides all the methods defined by the IO::Handle package.
