Explore 10 of the more useful Perl modules for YAML developers

Package Name

Description

URL

This module provides an object-oriented interface to serializing Perl objects to YAML and vice-versa. It includes both a loader and a dumper, and can be used to load a stream of YAML documents into a Perl script, or convert Perl data structures into a YAML document.

Use this module when you need to (de)serialize Perl data structures to YAML.

YAML

This module is useful for working with YAML document streams using an object-oriented approach. It is particularly good for incrementally or concurrently reading and writing multiple YAML documents within a single script.

Use this module when you need to read or write YAML document streams.

IO::YAML

This module lets you directly specify YAML markup in a Perl script, using filtering methods to convert this markup into Perl data structures.

Use this module to easily describe large and static Perl data structures in YAML.

Inline::YAML

This module provides a "tiny" implementation of the full YAML specification, making it possible to write more efficient YAML-based applications that have lower overhead and smaller memory footprints.

Use this module when you need a small-footprint application without necessarily complete YAML functionality.

YAML::Tiny

This module provides an object-oriented approach to managing configuration files in Perl. It uses YAML to express configuration directives, and supports both per-directory and global configuration files.

Use this module when you need to create or manipulate configuration files in Perl.

Config::YAML

This module provides functions to convert a YAML document into an HTML page, or to dynamically build and write an HTML document from YAML markup.

Use this module when you need a quick-and-dirty way to convert YAML markup into HTML.

YAML::Yaml2Html

This module lets you store CGI session data in a YAML container, and provides deserialization methods to access it both from Perl and other languages.

Use this module if you need to construct a custom data storage container for your session-based application.

CGI::Session::Serialize::yaml

This module provides a simple caching framework for a Web site. It allows you to cache the output of scripts and function calls as YAML, and reduce response times by rendering the cached pages to clients.

If your site receives a lot of traffic, use this module to reduce server load and page processing time by occasionally providing clients with snapshots from the page cache instead of the "live" page.

Cache::YAMLBackend

This module provides a unique way to combine Perl application logic with the simplicity of YAML structures, by providing a framework to nest structures and logic.

Use this module when you want to embed business logic into a data structure, to create reusable objects that can be transferred across applications.

YAML::Active

This module provides a framework for you to test YAML class implementations. It is particularly good at building reusable data driven patterns.

Use this module when you need to build a testing framework for YAML-based Perl applications.
