Devel::StackTrace::AsHTML adds as_html method to Devel::StackTrace which displays the stack trace in beautiful HTML, with code snippet context and function parameters. If you call it on an instance of Devel::StackTrace::WithLexicals, you even get to see the lexical variables of each stack frame.

This module is allows applications to retrieve per-user characteristics.

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.

This module opens a config file and parses its contents for you. The format of config files supported by Config::General is inspired by the well known Apache config format and is 100% compatible with Apache configs, but you can also just use simple name/value pairs in your config files. In addition to the capabilities of an Apache config file it supports some enhancements such as here-documents, C-style comments, and multiline options.

The Inline module allows you to put source code from other programming languages directly (inline) in a Perl script or module. The code is automatically compiled as needed, and then loaded for immediate access from Perl.

The Digest::HMAC module follows the common Digest:: interface for the RFC 2104 HMAC mechanism.

This module provides Path::Tiny types for Moose, Moo, etc. It handles two important types of coercion: coercing objects with overloaded stringification, and coercing to absolute paths. It also can check to ensure that files or directories exist.

This module verifies if requirements described in a CPAN::Meta object are present.

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.

This module converts Perl data structures to MessagePack and vice versa. MessagePack is a binary-based efficient object serialization format. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.

Crypt::MySQL emulates the MySQL PASSWORD() function. The module does not depend on an interface to the MySQL database server. This enables the comparison of encrypted passwords without the need for a real MySQL environment.

Crypt::CBC is a Perl-only implementation of the cryptographic Cipher Block Chaining (CBC) mode. In combination with a block cipher such as Crypt::Rijndael you can encrypt and decrypt messages of arbitrarily long length. The encrypted messages are compatible with the encryption format used by SSLeay.

The Text::Balanced module can be used to extract delimited text sequences from strings.

Template::Tiny is a reimplementation of a subset of the functionality from Template Toolkit in as few lines of code as possible.

It is intended for use in light-usage, low-memory, or low-cpu templating situations, where you may need to upgrade to the full feature set in the future, or if you want the retain the familiarity of TT-style templates.

This module in a fully object-oriented implementation of a simple n-ary tree.

Getopt::Tabular is a Perl 5 module for table-driven argument parsing, vaguely inspired by John Ousterhout's Tk_ParseArgv.

The DateTime::Set module provides a date/time sets implementation. It allows, for example, the generation of groups of dates, like "every wednesday", and then find all the dates matching that pattern, within a time range.

This module implements the algorithm for the solution of Bezier curves as presented by Robert D Miller in Graphics Gems V, "Quick and Simple Bezier Curve Drawing".

This module converts Perl data structures to JSON and vice versa.

This library allows communication with a smart card using PC/SC from a Perl script.

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.

Time::Duration::Parse is a module to parse human readable duration strings like "2 minutes" and "3 seconds" to seconds.

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

Lingua::Translit can be used to convert text from one writing system to another, based on national or international transliteration tables. Where possible a reverse transliteration is supported.
