EUGene allows you to manipulate and generate models. It can read UML class models in XMI independent from modeling, generate templates, transform models, and integrate in project building. It features independence in developer code and generated code. EUGene is independent from development tools. EUGene is easy to use and to put into place.
The Whole Platform is a technology for engineering the production of software. It provides an Eclipse-based Language Workbench for developing new languages, manipulating them using domain notations, and transforming them using a generative model driven approach. The languages bundled with the Whole Platform include: modeling languages; query and transformation languages; integration languages for grammars, XSD, RDB, and Java libraries; and popular languages such as Java and XML.
4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.
Acceleo is a code generator designed to efficiently implement the MDA approach (Model Driven Architecture) and to improve software development productivity. It is natively integrated with Eclipse and EMF. It includes tools and editors making it easy to learn and to adapt to any kind of project or technology. It provides incremental generation, meta-model interoperability, simple and extensible syntax, template driven customization, and more.
OpenXava is a framework to develop AJAX JavaEE/J2EE applications rapidly and easily. It allows you to define applications only with POJOs, JPA, and Java 5 annotations. It is feature rich and flexible. It generates JSR-168 portlet applications (Liferay, WebSphere Portal, Jetspeed, etc.).
JCPP is a complete, compliant, standalone, pure Java implementation of the C preprocessor. It is intended to be of use to people writing C-style compilers in Java using tools like sablecc, antlr, JLex, CUP, and so forth. It has been used to successfully preprocess much of the source code of the GNU C library.
pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML.
