Lincoln Stein states, "This perl 5 library uses objects to create Web fill-out forms on the fly and to parse their contents. It is similar to cgi-lib.pl in some respects. It provides a simple interface for parsing and interpreting query strings passed to CGI scripts. However, it also offers a rich set of functions for creating fill-out forms. Instead of remembering the syntax for HTML form elements, you just make a series of perl function calls. An important fringe benefit of this is that the value of the previous query is used to initialize the form, so that the state of the form is preserved from invocation to invocation.
Everything is done through a ``CGI'' object. When you create one of these objects it examines the environment for a query string, parses it, and stores the results. You can then ask the CGI object to return or modify the query values. CGI objects handle POST and GET methods correctly, and correctly distinguish between scripts called from <ISINDEX> documents and form-based documents. In fact you can debug your script from the command line without worrying about setting up environment variables."
Steven E. Brenner states, "The cgi-lib.pl library has become the de facto standard library for creating Common Gateway Interface (CGI) scripts in the Perl language. The cgi-lib.pl library makes CGI scripting in Perl easy enough for anyone to process forms and create dynamic Web content. Version 2.10 is the latest released version of cgi-lib.pl. New features in version 2 include support for file upload, improved robustness, and aids for debugging."
"libwww-perl is a library of Perl4 packages which provides a simple and consistent programming interface to the World-Wide Web. This library is being developed as a collaborative effort to assist the further development of useful WWW clients and tools. The library is based on version 4.036 of the Perl Programming Language."
The advantage of using these Bulletin Board Code tags is to restrict the usage of HTML/XHTML elements and to make formatting of posts easy to people that have no HTML/XHTML skill. This module addresses many security issues that UBBC tags may have with cross site script, also known as XSS.
Extremely flexible, general-purpose CGI script that uses a number of modules to accomplish almost anything. From the same form it is possible to direct different input variables to different files which are created according to user-defined format files. There is also an on-line form creation utility for the non-programmer.
A tiny Perl module implementing a simple yet powerful template engine for Web applications. It does not require installation and there is no complex macro language to learn - it literally takes only a few minutes to start working with. It is scalable from single-file scripts to large online interfaces.
A collection of some of the most common perl routines every perl programmer writes at one point. For example, a generic subroutine to parse form information, beginning, and ending a web page. All is free, and only needs a simple "require" statement within your code to work.
