Spirit is an object-oriented, recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow Spirit to approximate the syntax of Extended Backus Normal Form (EBNF) completely in C++. The Spirit framework enables a target grammar to be written exclusively in C++. EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.
RScheme is an object-oriented, extended Scheme implementation with a compiler that targets C or (RScheme's own) bytecodes. It has features expected from a modern language: an object system, reflection, modules, namespaces, safe macros, threads, a system call interface (including sockets), separate compilation, and persistence, as well as the formal basis and power of the Scheme programming language. RScheme also features a powerful, elegant foreign code interface.
CGI::Application::Generator provides a means by which a CGI::Application-based module can be created from code, as opposed to being written by hand. This module is intended to create the shell of an application module, based on the specification you provide. It will not output a completely functional application without additional coding. It will, however, create the structural parts of your application common to all CGI::Application-based modules. This module is intended to ease the creation of new CGI::Application modules and to encourage standardization of CGI::Application coding styles.
Javatempt is a template engine for Java that features an easy-to-learn template language. Templates are specified in a single file and are organized in terms of blocks and placeholders. Blocks may be recursive. A parser converts the template into a Java program for faster execution. Javatempt is ideal for code generation tasks or as a replacement to JSP.
myBeasties is a highly flexible evolutionary programming module. It is designed to be extendable and customisable for maximum use by the Perl developer. Many species of genotypes can be evolved, and these can be used to build phenotypes of any size or complexity. These can be as simple as a list or as large as a whole class of objects.
Javassist (Java programming assistant) is a load-time reflective system for Java. It is a class library for editing bytecodes in Java; it enables Java programs to define a new class at runtime and to modify a class file when the JVM loads it. Unlike other similar systems, Javassist provides source-level abstraction; programmers can use Javassist without detailed knowledge of the Java bytecode. This ease of use is a unique feature of Javassit against other tools.
Phptempt is a template engine for PHP and Java. Templates are precompiled and then included to the script/Java program as a PHP script/Java program. Templates are organized in blocks and placeholders, all placed in one single file. Blocks may be recursive. A version of the engine is available that is optimized for Java and particularly useful for the creation of code generators of any kind.
