JELAN provides facilities for constructing and invoking LL(1) language lexical analyzers and parsers. These are embedded in the sense that a language can be specified and then used for textual analysis within the same Java program. This avoids the need for a separate generation phase to write and compile a lexical analyzer and parser from the language specification.
The Karmasphere DP language is a high-performance non-blocking parallel language for performing data processing. It is designed to give the user a high degree of control over the usage of system resources, such as how many CPU cores or how much disk I/O time to use, without requiring the software developer to explicitly consider these issues in code. The implementation is a stand-alone library that can be used in any Java 1.5 environment. It can take full advantage of multiprocessor (SMP or NUMA) systems, and may be scaled sideways: since the interpreter and environment are stateless, an entire cluster of machines may run the interpreter in parallel without any need for synchronization.
XMLMath is a program that evaluates mathematical, logical, or textual expressions described in XML and prints the result. The package supports declarations of variables, sub-routines, and XML-based libraries with formulas that can be included in new expression documents. Xmlmath can be used as a stand-alone program from the command-line, but can also be used as a library inside third-party applications.
jNetStream is a sniffer and a protocol analyzer. A set of applications and complete Java library are provided with a comprehensive API. Hundreds of protocols have been defined, and the list can be expanded with a simple NPL language. It is appropriate for custom protocol development, grad students, and network teachers/professors.
The Hecl Programming Language is a high-level scripting language implemented in Java. It is intended to be small, extensible, extremely flexible, and easy to learn and use. It is intended as a complement to the Java programming language, not a replacement. As such, it tries to do well what Java doesn't, and leaves those tasks to Java for which it is best suited. It is also easy to add Hecl to Java, or write new Hecl commands in Java. It aims to be a very immediate language so that you can pick it up and start doing useful things with it quickly. Of particular interest is the fact that it's small enough to run on Java-enabled cell phones, so you can quickly script applications for them!
