cgi-util is a fast, easy to use C library for creating CGI programs. Functions are available for initialization (parsing), grabbing fields (by string, integer, double or boolean value), embedding HTML files, and more. It accepts both POST and GET request methods and has extensive error handling.
CGI::Application is a Perl framework intended to make it easier to create sophisticated, reusable Web-based applications. This module implements a methodology which can make Web software easier to design, easier to document, easier to write, and easier to evolve. CGI::Application builds on standard, non-proprietary technologies and techniques, such as the Common Gateway Interface and Lincoln D. Stein's excellent CGI.pm module. CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system, or Web server.
CGI::XMLForm allows properly written forms to generate complex XML structures on the backend. The form designer uses XSL/XQL style patterns to name form elements. This module then generates XML based on those form elements. The module also includes a very simple XQL-like search utility that aids building interactive XML editing applications.
cgic is an ANSI C-language library for the creation of CGI-based World Wide Web applications. cgic performs the following tasks: It parses form data, with browser correction, Transparently accepts both GET and POST form data, Handles line breaks in form fields in a consistent manner, Provides string, integer, floating-point, and single/multiple-choice functions to retrieve form data, provides bounds checking for numeric fields, loads CGI environment variables into C strings which are always non-null, and provides a way to capture CGI situations for replay in a debugging environment.
CGILua is a tool for developing dynamic HTML pages and manipulating input data from forms. It uses the interpreted language Lua for codifying its scripts. It has been on the road for almost 8 years now, being used in many Web products and sites. It is extensible through Lua libraries and dynamic loading of C/C++ libraries. Scripts can be written as Lua programs or HTML templates (HTML with Lua code embedded). Scripts are platform-independent.
