The inc::latest module helps bootstrap configure-time dependencies for CPAN distributions. These dependencies get bundled into the inc directory within a distribution and are used by Makefile.PL or Build.PL.

This module implements some sane defaults for Perl programs, as defined by two typical specimens of Perl coders.

Devel::REPL is a modern Perl interactive shell.

Text::ParseWords module is used to parse text into an array of tokens or array of arrays.

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.

A String::Util module of small, handy functions for processing strings in various ways.

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.

Bit::Vector is an efficient C library which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" and boolean matrices, all of arbitrary sizes. The package also includes an object-oriented Perl module for accessing the C library from Perl, and optionally features overloaded operators for maximum ease of use. The C library can nevertheless be used stand-alone, without Perl.

List::MoreUtils::XS provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

Pod::Simple is a Perl library for parsing text in the Pod (plain old documentation) markup language that is typically used for writing documentation for Perl and for Perl modules.

This module provides a convenient way to perform cleanup or other forms of resource management at the end of a scope. It is particularly useful when dealing with exceptions: the Scope::Guard constructor takes a reference to a subroutine that is guaranteed to be called even if the thread of execution is aborted prematurely. This effectively allows lexically-scoped "promises" to be made that are automatically honoured by perl's garbage collector.

File::pushd does a temporary chdir that is easily and automatically reverted, similar to pushd in some Unix command shells. It works by creating an object that caches the original working directory. When the object is destroyed, the destructor calls chdir to revert to the original working directory. By storing the object in a lexical variable with a limited scope, this happens automatically at the end of the scope.

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

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

Devel::CheckCompiler is a tiny module to check whether a compiler is available. It can test for a C99 compiler, or you can tell it to compile a C source file with optional linker flags.

Cwd::Guard changes the current directory using a limited scope. It returns to the previous working directory when the object is destroyed.

It's boring to deal with opening files for IO, converting strings to handle-like objects, and all that. With Mixin::Linewise::Readers and Mixin::Linewise::Writers, you can just write a method to handle handles, and methods for handling strings and file names are added for you.

This module provides convenience methods that let you easily create DateTime::Set objects for RFC 2445 style recurrences.

Text::Tabs will add or remove tabs from a document. Text::Wrap will reformat lines into paragraphs.

Manipulating stashes (Perl's symbol tables) is occasionally necessary, but incredibly messy, and easy to get wrong. This module hides all of that behind a simple API.

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 is intended to easily load initialization values for attributes on object construction from an appropriate config file. The building is done in MooX::ConfigFromFile::Role---using MooX::ConfigFromFile ensures that the role is applied.

Text::Glob implements glob(3) style matching that can be used to match against text, rather than fetching names from a file system. If you want to do full file globbing use the File::Glob module instead.

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.
