The CPAN module automates or at least simplifies the make and install of perl modules and extensions. It includes some primitive searching capabilities and knows how to use LWP, HTTP::Tiny, Net::FTP and certain external download clients to fetch dist...

This module provides functions for determining the pathname of the current working directory. It is recommended that getcwd (or another *cwd() function) be used in *all* code to ensure portability. By default, it exports the functions cwd(), getcwd()...

• File::Spec - portably perform operations on file names

I list here some of the most important methods in "Module::Build". Normally you won't need to deal with these methods unless you want to subclass "Module::Build". But since one of the reasons I created this module in the first place was so that subcl...

This is the official Perl driver for MongoDB <http://www.mongodb.com>. MongoDB is an open-source document database that provides high performance, high availability, and easy scalability. A MongoDB server (or multi-server deployment) hosts a number o...

Software distributions released to the CPAN include a META.json or, for older distributions, META.yml, which describes the distribution, its contents, and the requirements for building and installing the distribution. The data structure stored in the...

Surely the CPAN doesn't need yet another CSV parsing module. Text::CSV_XS is the standard parser for CSV files. It is fast as hell, but unfortunately it can be a bit verbose to use. A number of other modules have attempted to put usability wrappers a...

What is a template? A template is a text file with variables in it. When a template is parsed, the variables are interpolated to text. (The text can be a few bytes or a few hundred kilobytes.) Here is a simple template with one variable ('$NAME'): He...

The "Path::Class::Dir" class contains functionality for manipulating directory names in a cross-platform way....

• Path::Class - Cross-platform path specification manipulation
• Path::Class::File - Objects representing files
• Path::Class::Entity - Base class for files and directories

In basic operation, each of the handlers Filter1, Filter2, and Filter3 will make a call to $r->filter_input(), which will return a filehandle. For Filter1, the filehandle points to the requested file. For Filter2, the filehandle contains whatever Fil...

This module contains a simple S/Key calculator (as described in RFC 1760) implemented in Perl. It exports the function "key" by default, and may optionally export the function "compute". "compute_md4", "compute_md5", "compute_sha1", "key_md4", "key_m...

This module provides methods for obtaining information about the currently running perl interpreter. It originally began life as code in the "Module::Build" project, but has been externalized here for general use....

This module provides a standard way to gather metadata about a .pm file through (mostly) static analysis and (some) code execution. When determining the version of a module, the $VERSION assignment is "eval"ed, as is traditional in the CPAN toolchain...

"DBIx::Migration::Directories" provides you with a framework for managing database schemas easily. You create a directory to hold your schema, then in that directory create sub-directories containing the SQL code to install, remove, upgrade, or downg...

This module implements a perl interface to Thorsten Joachims' SVMLight package: SVMLight is an implementation of Vapnik's Support Vector Machine [Vapnik, 1995] for the problem of pattern recognition, for the problem of regression, and for the problem...

This module can build the C portions of Perl modules by invoking the appropriate compilers and linkers in a cross-platform manner. It was motivated by the "Module::Build" project, but may be useful for other purposes as well. However, it is *not* int...

Dr. Steven Wolfram describes in his book, A New Kind of Science, ISBN:1-57955-008-8 his path-breaking experiment where he comprehensively explored a mathematical function which can be described (by me see the reference for a detailed explanation) as ...

This module facilitates the conversion of numbers between various number bases. You may define your own digit sets, or use any of several predefined digit sets. The to_base() and from_base() methods convert between Perl numbers and strings which repr...

Part-of-speech tagging is the act of assigning a part-of-speech label (noun, verb, etc.) to each token of a natural-language sentence. There are many different ways to do this, resulting in lots of different styles of output and using various amounts...

This module tries to make install path resolution as easy as possible. When you want to install a module, it needs to figure out where to install things. The nutshell version of how this works is that default installation locations are determined fro...

The "Statistics::Contingency" class helps you calculate several useful statistical measures based on 2x2 "contingency tables". I use these measures to help judge the results of automatic text categorization experiments, but they are useful in other s...
