openASN.1 is an Open Source Java toolkit for the Abstract Syntax Notation One (ASN.1) which consists of a compiler and codec with a low footprint runtime library.
More Than Parsing is a parser generator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
STDL (Structured test description language) is a domain-specific testing language that is used to auto-generate unit test code. It supports a myriad of output languages (incl. C#). The project's aim is that of reducing the resources required for testing
JUndo is a declarative object-oriented programming language with functional, and intensional programming characteristics. Applications include multi-level undo and sophisticated error recovery. See http://verdantium.blogspot.com/
Jo2 (Java Operators Overloading) :: is Javac (Sun Java Compiler) extended by operators overloading. This open java project comes with a specification of operators overloading in Java. The resulting byte code obeys to the java standard specification.
TreeDL (Tree Description Language) is a notation for tree structures used by programs (like syntax trees) and tool for translation of tree descriptions to target programming language, docs generation, etc. Tool's functionality can be extended by plugins.
The Tree Processing Language allows the specification of an object oriented tree structure, with strong seperation of concerns, which can be compiled into a type safe class hierarchy implementing the tree.
A script(ing/ed/able) optimizing compiler for the C and Objective-C languages (and in the future other languages such as C++, D and Java). Written in a scripting language to allow for experimentation with code generation and optimization techniques.
Covra is a project to help design compilers. C3 is a tool specialized on the easy design and construction of ASTs, it is independent of the compiler compilers or parser generator that is used. It generates Java and C# code. Require JRE 1.6.0.
MiniLang is yet another scripting language written in Java programming language. Main features : Functional language, Strongly interact with Java, XML integration, Statickly typed, Integrated template engine like Velocity or Smarty...
