Retrotranslator is a Java bytecode transformer that translates Java classes compiled with JDK 5.0 into classes that can be run on JVM 1.4. Supported features include generics, annotations, reflection on generics and annotations, enums, autoboxing, foreach loops, varargs, covariant return types, formatted output, static import, concurrency utilities, and collections framework enhancements.
Red language is a native-code compiled functional, imperative, symbolic, and homoiconic programming language that re-uses most of REBOL's syntax and semantics. Both static and JIT compilation support are planned. A strong emphasis is made on concurrency and both task and data parallelism support using an actor-like abstraction and parallel collections (Scala-like). The target range of usage spreads from low-level system programming (thanks to the built-in Red/System C-level DSL) and embedded systems, up to high-level scripting, with an optional REPL console.
Rhope is a dynamically typed dataflow programming language that also borrows some ideas from other paradigms. Unlike mainstream programming languages, statements are not necessarily executed in the order they are written, but instead based on their dependencies. Statements that do not share dependencies run in parallel. Most operations have value semantics (i.e. modifying an object makes a copy rather than changing the original) making this parallelism safe. For managing global state, Rhope has a transaction mechanism.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages including mixins, algebraic datatypes with pattern matching, genericity, and more. It is well integrated with Java and .NET: the Scala compiler produces standard Java class files or .NET assemblies, and Java/.NET libraries and frameworks can be used without glue code or additional declarations.
The Objeck computer language is an object-oriented computing language with functional features that has ties with Java, C#, and Pascal. In this language, all data types are treated as objects. The language consists of a compiler and VM with an accompanying memory management and JIT compiler.
mdocml is a suite of tools for compiling "-mdoc", the roff macro package of choice for BSD manual pages, and "-man", the predominant historical package for UNIX manuals. The mission of mdocml is to deprecate groff, the GNU roff implementation, for displaying -mdoc pages whilst providing token support for -man.
Sfront compiles MPEG 4 Structured Audio (MP4-SA) programs into efficient C programs that generate audio when executed. MP4-SA is a standard for normative algorithmic sound, which combines an audio signal processing language (SAOL) with score languages (MIDI and SASL). Under Mac OS X and Linux, sfront supports real-time, low-latency audio input/output and MIDI input. Under Mac OS X, sfront supports the creation of AudioUnit plug-ins. The documentation includes a book about SAOL programming.
