The Artistic License refers most commonly to the original Artistic License ( version 1. 0 ), a software license used for certain free and open source software packages, most notably the standard Perl implementation and most CPAN modules, which are dual-licensed under the Artistic License and the GNU General Public License ( GPL ).

CPAN, the Comprehensive Perl Archive Network, is an archive of over 100, 000 modules of software written in Perl, as well as documentation for it.

CPAN can denote either the archive network itself, or the Perl program that acts as an interface to the network and as an automated software installer ( somewhat like a package manager ).

CPAN is also used to distribute new versions of Perl, as well as related projects, such as Parrot.

The CPAN is an important resource for the professional Perl programmer.

With over 23, 000 modules ( containing 20, 000, 000 lines of code ) as of July 2011, the CPAN can save programmers weeks of time, and large Perl programs often make use of dozens of modules.

Finally, the natural hierarchy of Perl module names ( such as " Apache :: DBI " or " Lingua :: EN :: Inflect ") can sometimes be used to browse modules in the CPAN.

Several search engines have been written to help Perl programmers sort through the CPAN.

There is also a Perl core module named CPAN ; it's usually differentiated from the repository itself by calling it CPAN. pm.

An interactive shell called < tt > cpan </ tt > is also provided in the Perl core, and is the usual way of running CPAN. pm.

Authors can upload new distributions to the CPAN through the Perl Authors Upload Server ( PAUSE ).

Experienced Perl programmers often comment that half of Perl's power is in the CPAN.

The CPAN has grown so large and comprehensive over the years that many people learning Perl seem to elevate it to a sort of mythical status, and express surprise when they begin to encounter topics for which a CPAN module doesn't exist already.

As a hive of activity in the Perl world, the CPAN both shapes and is shaped by Perl culture.

Several Perl modules available from CPAN provide serialization mechanisms, including and.

* Text :: Metaphone Perl module from CPAN

* Text :: DoubleMetaphone Perl module from CPAN

* Perl, via the CPAN modules Class :: Contract ( by Damian Conway ) or Carp :: Datum ( by Raphael Manfredi ).

* Damian Conway's Class :: Contract Perl module from CPAN

* Raphael Manfredi's Carp :: Datum Perl module from CPAN

** CGI. pm, a Perl module for implementing Common Gateway Interface programs

* Parse :: Earley A Perl module that implements Jay Earley's original algorithm.

xYzZY is used as the default boundary marker by the Perl HTTP :: Message module for multipart MIME messages, and was used in Apple's AtEase for workgroups as the default administrator password in the 1990s.

*, a Perl module that claims to generate actual random numbers from interrupt timing discrepancies.

The module is a lightweight, low dependency Pure Perl module for UUID creation and testing.

* Text :: Capitalize, a Perl module for English capitalization

** Lingua :: EN :: NameCase, a Perl module for Western European name capitalization

The system uses the Perl language with a database interface module for processing and PostgreSQL for data storage.

* Perl module, a discrete component of software for the Perl programming language.

* Many access methods: native / API, dbExpress drivers, ODBC, OLEDB,. Net provider, JDBC native type 4 driver, Python module, PHP, Perl

* Math :: Random :: ISAAC, a Perl module implementation of the algorithm

The latest DBI module for Perl from CPAN can run on a range of operating systems.

In collaboration with others, Tim Bunce began specifying DBI in 1992. the Perl community maintains DBI as a CPAN module in accordance with the open source model.

* Lingua :: Rhyme :: FindScheme — Perl module to find the rhyme scheme of a given text.

* The Perl HL7 Toolkit, an Open-Source HL7 Perl module

Berkeley DB is written in C with API bindings for C ++, PHP, Java, Perl, Python, Ruby, Tcl, Smalltalk, and most other programming languages.

In 2003, the www. cpan. org domain name was redirected to Matt's Script Archive, a site infamous in the Perl community for having badly written code.

Even outside the Acme :: hierarchy, some modules are still written largely for amusement ; one example is Lingua :: Romana :: Perligata, which can be used to write Perl programs in a subset of Latin.

Numerous modules and Perl scripts have been made available for Irssi to customise how it looks and operates.

The intermediate representation can be compiled once and for all ( as in Java ), each time before execution ( as in Perl or Ruby ), or each time a change in the source is detected before execution ( as in Python ).

For example, Eclipse and Netbeans have plugins for C / C ++, Ada, GNAT ( for example AdaGIDE ), Perl, Python, Ruby, and PHP, among other languages in use.

Larry Wall ( born September 27, 1954 ) is a computer programmer and author, most widely known for his creation of the Perl programming language in 1987.

Wall developed the Perl interpreter and language while working for Unisys.

He is the co-author of Programming Perl ( often referred to as the Camel Book and published by O ' Reilly ), which is the definitive resource for Perl programmers ; and edited the Perl Cookbook.

He also often uses linguistic terms for Perl language constructs, so instead of traditional terms such as " variable ", " function ", and " accessor " he sometimes says " noun ", " verb ", and " topicalizer ".

Wall continues to oversee further development of Perl and serves as the Benevolent Dictator for Life of the Perl project.

MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack — LAMP is an acronym for " Linux, Apache, MySQL, Perl / PHP / Python.

* Maatkit-a cross-platform toolkit for MySQL, PostgreSQL and Memcached, developed in Perl.

While this is not uncommon for modern languages such as Perl or JavaScript, it was a highly unusual feature in the late 1970s.
