Perl Module

What is a Perl Module?

A Perl module is a reusable "add-on" for the Perl programming language that extends its capabilities with a set of related, ready-made functions.

A Perl module is essentially a library of related functions contained in a single file, specifically designed to be reused by other modules or programs. Some modules are included with every distribution of Perl - these are referred to as "core" modules.

How do I install a Perl module?

Additional Perl modules can be readily installed into an existing Perl installation. There are over 200,000 modules available through CPAN. Our guide How to install Perl modules walks you through the process.

Some modules require other modules in order to work; these are called "dependencies". When you install a module, any dependencies it requires are usually installed automatically alongside it.

Perl modules and MIDAS

MIDAS is written in Perl and is designed to rely only on Perl's core modules wherever possible. This deliberate choice keeps a self-hosted MIDAS installation simple, minimizing the number of additional modules you need to obtain from CPAN.
