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

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 intended as a drop-in replacement for NEXT, supporting the same interface, but using Class::C3 to do the hard work.

Ref::Util introduces several functions to help identify references in a smarter (and usually faster) way. The difference with conventional approach:

• No comparison against a string constant

• Supports blessed variables

• Supports tied variables and magic

• Ignores overloading

• Ignores subtle types

• Usually faster

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.

This package contains SGMLS.pm, a perl5 class library for parsing the output from an SGML parser such as OpenSP. It also includes the sgmlspl command, an Perl script showcasing how the library can be used.

Sometimes you need to test what happens when a given module is not installed. This module provides a way of temporarily hiding installed modules from perl's require mechanism. The Module::Mask object adds itself to @INC and blocks require calls to restricted modules.

This module converts Perl data structures to JSON and vice versa using either JSON::XS or JSON::PP.

Storable brings persistence to your Perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time.

Reply is a lightweight, extensible REPL for Perl. It is plugin-based (see Reply::Plugin), and through plugins supports many advanced features such as coloring and pretty printing, readline support, and pluggable commands.

This toolkit primarily provides modules for performing both traditional and object-oriented i/o) on things *other* than normal filehandles; in particular, IO::Scalar, IO::ScalarArray, and IO::Lines.

Term::ProgressBar provides a simple progress bar on the terminal, to let the user know that something is happening, roughly how much stuff has been done, and maybe an estimate at how long remains.

This package enables you to do generic message logging throughout programs and projects. Every message will be logged with stacktraces, timestamps and so on. You can use built-in handlers immediately, or after the fact when you inspect the error stack. It is highly configurable and lets you even provide your own handlers for dealing with messages.

Module::Install is a package for writing installers for CPAN (or CPAN-like) distributions that are clean, simple, minimalist, act in a strictly correct manner with ExtUtils::MakeMaker, and will run on any Perl installation version 5.005 or newer.

Sys::Hostname::Long tries very hard to get the full hostname of a system.

Date::Manip is a series of modules for common date/time operations, such as comparing two times, determining a date a given amount of time from another, or parsing international times.

This module implements the C3 algorithm, which aims to provide a sane method resolution order under multiple inheritance.

This module provides a Perl interface to the iconv() codeset conversion function, as defined by the Single UNIX Specification. For more details see the POD documentation embedded in the file Iconv.pm, which will also be installed as Text::Iconv(3) man page.

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).

This module can serve as a transparent interface to any TIEHASH package that is required to store arbitrary perl data, including nested references. Thus, this module can be used for storing references and other arbitrary data within DBM databases.

This module exposes interpreter threads to the Perl level.

This package provides an ASCII mapping for the eucJP encoding.

Crypt::DES is an XS-based implementation of the DES cryptography algorithm. The module implements the Crypt::CBC interface which has blocksize, keysize, encrypt and decrypt functions.

Xslate is a template engine, tuned for persistent applications, safe as an HTML generator, and with rich features. The core design principle is that template logic does not have access outside the template without permission.
