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.
SteelBlue is an Open Source Web application server similar to Cold Fusion. It extends HTML with tags to execute SQL commands, perform type checking on user input, loop over sections of code, and manipulate data. In addition, it has a Perl-like scripting language that can be embedded directly into the HTML for complex data manipulation. SteelBlue runs as a CGI script on Linux, UNIX variants (via gcc 2.8), and Win32. It includes native support for most popular relational databases and the embedded scripting language is extensible though a C++ API. Included in the distribution are a book about programming SteelBlue, many examples, and a full bulletin board application.
C Scripting Language (CSL) is an embeddable scripting language with C syntax. A comprehensive set of libraries is included in the base package, and writing your own libraries is possible with an easy API for C programs, as well as a class interface for C++ programs. If you are looking for a compact and powerful scripting engine for your application, CSL might be the choice.
X2c is an Xbase compiler that creates executable programs from Xbase source on any Unix or C platform. This is accomplished by creating C source from the Xbase source, compiling, and linking with included Xbase function libraries. Whilst the C source is considered an intermediate stage for X2c, it can be used and developed as any other C source. The X2c dialect of Xbase accepts virtually all statements from Borland (was Ashton-Tate), dBASE III PLUS, Computer Associates (was Nantucket), Clipper (Summer '87), and Microsoft (was Fox Software) FoxBASE (2.1). Selected Foxpro statements are also supported.
Moto is a server-side scripting language much like PHP or ColdFusion. The difference between Moto and other server-side scripting languages is that Moto pages can run interpreted (like PHP) or be natively compiled into dynamically loadable Apache modules (an entire Web site could be compiled into one .so file). It comes with a full suite of objects and functions for state and session management, MySQL and PostgreSQL database connectivity, and a slew of utility classes like stacks, hashtables, string buffers, etc. There is also an included interface definition language for exposing C functions to Moto. All object allocation occurs in a shared memory segment, so maintaining state in objects between page views is a snap.
