Jasmin is a Java Assembler. It takes ASCII descriptions for Java classes, written in a simple assembler-like syntax. It converts them into binary Java .class class files suitable for loading into a Java Virtual Machine implementation.

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

X10 is a class-based, strongly-typed, garbage-collected, object-oriented language. To support concurrency and distribution, X10 uses the Asynchronous Partitioned Global Address Space programming model (APGAS). This model introduces two key concepts -- places and asynchronous tasks -- and a few mechanisms for coordination. With these, APGAS can express both regular and irregular parallelism, message-passing-style and active-message-style computations, fork-join and bulk-synchronous parallelism. Both its modern, type-safe sequential core and simple programming model for concurrency and distribution contribute to making X10 a high-productivity language in the HPC and Big Data spaces. User productivity is further enhanced by providing tools such as an Eclipse-based IDE (X10DT). Implementations of X10 are available for a wide variety of hardware and software platforms ranging from laptops, to commodity clusters, to supercomputers.

The Mozart Programming System is an open source implementation of the programming language Oz 3. Oz is a multi-paradigm language that supports declarative programming, object-oriented programming, constraint programming, concurrency and distributed programming as part of a coherent whole.

A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR and combines with the Extensions for OpenJDK for OpenJ9 repo. We're not sure which route you might have taken on your way here, but we're really pleased to see you! If you came directly from our website, you've probably already learned a lot about Eclipse OpenJ9 and how it fits into the OpenJDK ecosystem. Eclipse OpenJ9 is an independent implementation of a Java Virtual Machine. "Independent implementation" means it was built using the Java Virtual Machine specification without using any code from any other Java Virtual Machine. The OpenJ9 JVM combines with the Java Class libraries from OpenJDK to create a complete JDK tuned for footprint, performance, and reliability that is well suited for cloud deployments. The original source contribution to OpenJ9 came from the IBM "J9" JVM which has been used in production by thousands of Java applications.

MyJIT is a small library allowing to (JIT) compile intermediate language into the machine code and subsequently execute it.

SPCC is a lightweight, portable C compiler and a Virtual Machine.

Clipper/XBase compatible compiler with initial support other xBase dialects. Multitasking, OOP,SIX/Comix, SQL and ODBC drivers,a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), ....

fun4j brings functional programming to the JVM. It's a framework that integrates major concepts from functional programming into the Java Platform. It also provides seamless integration of Java with Lisp coding, by using a lisp-to-bytecode compiler.

Intermediate Language Distributed Just-In-Time (ILDJIT) is a unified compilation framework for CIL bytecode. It is a parallel and easily extensible framework thanks to its internal structure composed by plugins.

Dyalect is a dynamic programming language for .NET Core platform. It is lightweight, fast and modern. Dyalect (or Dy for short) is written in C# and has zero dependencies except for standard .NET Core libraries, which means that it can seamlessly run on Windows, MacOS and Linux. Moreover you can use the same binaries on any of these platforms! Dy runs on the top of its own high performance virtual machine. It compiles fast and can be used as an embeddable language or as a scripting language of your choice. It is also a good language to learn programming. Dyalect offers modern syntax, inspired by such languages as C#, Swift, Go and Rust, first class functions, coroutines, expressive modules, a dynamic type system with an ability to extend existing types with new functions and much more. Dy is shipped with a crossplatform interactive console. Main repo: https://github.com/vorov2/dyalect

A general purpose, object-oriented script language that compiles into code for a register based virtual machine. The language is quite similar to object-oriented high-level languages like Java and C#. The library is entirely self-sufficient and ANSI C compliant. It's main purpose is to be embedded in any application to allow automation of that application through scripting. An integrated C++ binding code generator allows you to create bindings for your application's classes in seconds. The integrated HTML documentation generator allows you to create documentation for your native bindings in seconds. The project is released under the zlib/libpng license. It has been in development for over 10 years and offers some powerful features. Extensive information, documentation, articles and code examples can be found at the developer blog.

Port of the Pascal-P4 compiler to Free Pascal and Delphi. The source code of Pascal-P4 is commented in the book "Pascal Implementation" by Steven Pemberton and Martin Daniels. The book is readable online at http://homepages.cwi.nl/~steven/pascal/

Compiler of Lisp programs to a platform-idependent bytecode and the corresponding virtual machine.

AngelScript is an extremely flexible cross-platform scripting library designed to allow applications to extend their functionality through external scripts. It has been designed from the beginning to be an easy to use component. This repository is now archived with no further updates. Please visit angelcode.com/angelscript for information on updates.

Here you will find a collection of BCPL tools I've gathered from the net, cleaned up and ported to the Atari ST. This involved fixing bugs, reducing stack usage and making the code compile in 16bit via Pure C (Turbo C for the Atari ST). Source credits include: Martin Richards - BCPL Kit http://www.cl.cam.ac.uk/~mr10/ Robert Nordier (Translated interp to C) http://www.nordier.com/ Serge Vakulenko (Translated cg/syn/trn to C) https://github.com/sergev/b I'm sure there are other names, but those are the ones on the source files. The code now compiles clean for the Atari ST, so it should work for anything else.

Cminor is a general-purpose, object-oriented garbage collected experimental programming language whose core statements and expression are borrowed from C#. Cminor programs run in a virtual machine.

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

Command Script 4 (CSC4) is an "application control" or application extension scripting language / virtual machine / compiler environment. CSC4 supports object member access, object creation and static calls to the underlying .NET Framework 2.0.
