Embperl gives you the power to embed Perl code in your HTML or XML/XSLT documents and the ability to build your Web site out of small reusable objects in an OO-style. It can also build taglibs and use caching. You can also take advantage of hundreds of Perl modules which have already been written for such tasks as database access to a growing number of database systems. Embperl has several features especially useful for creating HTML, including dynamic tables, formfield-processing, escaping/unescaping, session handling, and more. Embperl is a server-side tool, which means that it's browser-independent. It can run in various ways: under mod_perl, as a CGI script, or offline.
HTML::EP is a server-side embedded HTML system in the style of PHP3, that allows you to combine the full power of Perl with your HTML pages. HTML::EP runs as a separate CGI binary or (for full speed) as a mod_perl package. It includes database access via DBI, the Perl Database Interface, session support and allows quite easy extension via a modular, OO interface.
HTML::EP::Explorer is an interface in the style of the Windows Explorer that allows your users to select files located on your Unix server and execute actions on them. In particular you may select them for printing. The system includes a security systems that allows you to restrict access to certain areas.
The HTML::Template module attempts to make using HTML templates simple and natural. It extends standard HTML with a few new tags for variables, loops, if/else blocks and includes. A file written with HTML and these new tags is called a template. Using this module you fill in the values for the variables and loops declared in the template. This allows you to seperate design (the HTML) from the data, which you generate in the Perl script. While there are many other HTML template systems available, this module is simple and fast. It doesn't try to reinvent Perl CGI, it just augments HTML with a few new and very useful abilities.
The Image::Size module for Perl provides a clean interface for fetching image dimensions (and type, when unknown) from graphics files in a wide variety of common formats. It is a pure Perl extension (no C or XS linking required) that has been tested on a variety of UNIX, Linux and BSD systems, as well as MacPerl and Windows ports of Perl. It was designed around and tuned for use in CGI application development, but is useful in other areas as well.
IOG is a network I/O byte grapher made to graph cumulative KB/MB/GB totals for hours/days and months. It is intended to be simple, fast (support thousands of interfaces) and integrate well with MRTG (not required). Data for each host is updated hourly and HTML graphs are created. It uses a data consolidation algorithm which allows for a small, non-growing database file for each host. Perl is required, but no external graphing libraries or binaries are needed.
