cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
FormMagick is a set of Perl modules intended to ease the task of writing multi-page Web forms. It takes a description of the form (fields, validation to perform on each field, etc) in XML format and generates HTML on the fly. Other features include templates for changing the "look and feel" of your forms, and the ability to easily localise your text for other languages.
HTML::Mason is a full-featured web site development and delivery system. Mason allows web pages and sites to be constructed from shared, reusable building blocks called components. Components contain a mix of Perl and HTML, and can call each other and pass values back and forth like subroutines. Components increase modularity and eliminate repetitive work. HTML::Mason is most powerful when used in conjunction with mod_perl, but can be used in standalone applications as well.
DBIx::Browse handles the browsing of relational tables with a human-like interface via the Web. It transparently translates SELECTs, UPDATEs, DELETEs, and INSERTs from the desired "human view" to the values needed for the table. This is the case when you have related tables (1 to n) where the detail table has a reference (FOREIGN KEY) to a generic table (e.g., Customers and Bills) with some index (typically an integer).
The HTML::Defaultify Perl module is designed to allow CGI programmers to present forms with some fields filled in, which is handy for letting users correct bad input, show records to be edited, and much more. The main function, defaultify(), takes any block of HTML and a hash of field names and values, and returns the HTML with the form fields set to those values. Value lists for multiple same-named fields are supported, as are pages with multiple forms. Several different input formats are supported for compatibility with existing tools.
AppWrap is a content management system for enterprises. It is built on a template engine that includes a framework for building SQL tables and allowing users to populate and maintain these tables. Reports using data from these tables can be easily created using another template. It is ideal for quickly Webifying Excel and Word files shared among workgroups and rapidly providing advanced data management and presentation capabilities. It is intended for managing mildly dynamic data without the labor of hand-coding and managing multiple CGI forms and templates, or the expense of CRM systems.
CGI.pm uses objects to create Web fill-out forms on the fly and to parse their contents. Instead of remembering the syntax for HTML form elements, developers can 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.
The Perl Oak Component Tree is a set of objects designed to provide the maximum reusability to software development. Oak can be used in any development platform, but just the Web platform is implemented. In Oak, you define an XML file to each page and you will implement just the events.
