Open Source Virtual Machine Software

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.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

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.

The Ring is a practical general-purpose multi-paradigm language. The supported programming paradigms are imperative, procedural, object-oriented, declarative using nested structures, functional, meta programming and natural programming. The language is portable (MS-DOS, Windows, Linux, macOS, Android, WebAssembly, Microcontrollers, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be simple, small and flexible. Ring is distributed as a Free-Open Source project under the MIT License.

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.

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.

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.

ExStudio is a set of development tools for the "Ex" virtual machine. It includes the vm itself, a compiler, an assembler and a debugger.

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.

Multi-platform execution environment for applications (and libraries) based on bytecode (compile once, run anywhere). Support for multi-language and multi-paradigm. It intends to be an open alternative to the Java and MS.NET platforms.

The MCAScript programming language consists of a subset of C# extended by special statements from hardware programming languages. It has been developed to be used within the MCA(Modular Controller Architecture) to script to behaviour of robots.

NanoCL is a simple command language with syntax based on TCL implemented in C++. NanoCL is designed to provide simple scripting language, configuration file format as well as interactive console to games and GUI applications.

Self-hosting environment for the (new) P1 Programming Language including a portable compiler, debugger, virtual machine and an optimizing native compiler.

ParaPascal is a programming language, an integrated development environment and simulator for learning concurrent programming.

Que is a queue-based programming language, very different from other programming languages. Due to the nature of a queue, programs made in Que are automatically parallelized, meaning improved efficiency in multi-core environments.

Java bytecode to native code compiler striving for small, standalone executables.

Kaya: A statically typed, imperative cross-platform programming language with type inference, powerful data description capabilities and built-in abstractions and libraries for easy and robust web application development. http://kayalang.org/

Macro Scipting Language (MSL) is a light weight perl-like scripting language that is intended to be added to existing or new applications to provide macro support. It can also run standalone as well. The syntax is very close to perl and c.

The nap scripting language is an object oriented scripting language which brings together the best features of various scripting languages found on different platforms. The nap-script is a C like programming and scripting language with the following characteristics: - compiles into bytecode - it runs in a virtual machine - can be executed standalone or embedded in C/C++ code - has a well defined assembly language - can do runtime compilation - has a syntax very similar to C without pointers ... and it is still under development :) Check out the mercurial repository to get a glimps on the code.

OS for embedded and mobile devices based on tiny byte-code interpreter and FORTH language compiler (into platform-independent byte-code). In other word its smallest programming language realization works on any type computer with any OS

ubcc is a just-in-time compiler for various bytecodes. It is designed for use in operating system kernels.
