zmaildrop is a mail delivery agent (MDA) specifically designed to analyze emails, extract relevant information, and send it to a Zabbix server. It is designed for use with schedulers, backup tools, and security monitoring tools that report information via email. As an MDA, it integrates easily with mail transfer agents (MTA) such as Postfix, Exim, and Qmail, or mail retrieving tools as Fetchmail. It is highly configurable, using a simple YAML syntax to describe tool-specific mail formats.
ORMesque is an object relational mapper for the Dancer framework that provides a database connection to the database of your choice and automatically creates objects and accessors for that database and its tables and columns. It uses the SQL::Abstract querying syntax, and can also be used as a standalone ORM. It is a great alternative when you don't have the time, need, or desire to learn DBIx::Class.
The Tcl extension provides a small but complete interface into libtcl and any other Tcl-based library for Perl programmers. It lets you create Tcl interpreters (as Perl 5 objects), bind in commands to them (either Perl subroutines or C functions dynamically loaded with the DynaLoader extension), and execute Tcl code in those interpreters.
Chart::Clicker aims to be a powerful, extensible charting Perl package that creates really pretty output. Charts can be saved in PNG, SVG, PDF, and PostScript format. Clicker leverages the power of Graphics::Primitive to create snazzy graphics without being tied to a specific backend.
CHI provides a unified caching API for Perl, designed to assist a developer in persisting data for a specified period of time. The CHI interface is implemented by driver classes that support fetching, storing, and clearing of data. Driver classes exist or will exist for the gamut of storage backends available to Perl, such as memory, plain files, memory mapped files, memcached, and DBI. CHI is intended as an evolution of DeWitt Clinton's Cache::Cache package, adhering to the basic Cache API but adding new features and addressing limitations in the Cache::Cache implementation.
Text::Xslate is a template engine, tuned for persistent applications, safe as an HTML generator, and with rich features. The concept of Xslate is sandboxing. The template logic should have no access outside the template beyond your permission. Templates are compiled into intermediate code and then executed by the virtual machine, which is highly optimized for rendering templates. Xslate supports template cascading, which allows you to extend templates with block modifiers.
