CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

Squirrel is a light weight programming language featuring higher-order functions,classes/inheritance,delegation,tail recursion,generators,cooperative threads,exception handling, reference counting and garbage collection on demand. C-like syntax.

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.

SableCC is a parser generator which generates object-oriented frameworks for building compilers, interpreters and other text parsers. SableCC keeps a clean separation between machine and user code which leads to a shorter development cycle.

In this project we aim to develop scheme libraries for developing various web applications (especially servlets and xml-based web services). Our approach is to use jscheme (an open source implementation of scheme in Java) as the core language which allow

The Portable Forth Environment implements the ANSI Forth Standard, it is fully written in C, the newer version has a module concept, and it is fully multithreaded. Autoconf used. Tested in embedded environments.

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

We extend the Eclipse IDE with tools for development in Haskell, a functional programming language, providing support for a wide range of tools (compilers, interpreters, doc tools etc.) in a coherent, convenient and configurable environment.

Psyco showed that it is possible to execute Python code at speeds approaching that of fully compiled languages, by "specialization". The project is now dead and replaced by PyPy: http://pypy.org/

Beaver is a LALR compiler compiler for Java that uses several techniques to generate very fast parsers.

This project will allow a group of people to develop the Euphoria programming language: interpreter, translator, binder, documentation etc. For more information visit https://openeuphoria.org

Smith is an open source, cross-platform ColdFusion® engine, written entirely in Java. Running on top of Java Runtime Environment and Java Servlet Container, it can be deployed virtually on any operating system and work with any web server.

This project is dedicated to developing more readable format(s) for Lisp-based languages (such as Common Lisp and Scheme) and implementing those formats (readers, pretty-printers, editor macros, etc.). MIT license preferred, to spread them widely.

VolksForth is a 16bit Forth System with the goal to produce a manageable Forthsystem for computer systems with restricted system resources.

The XPS is a scalable platform for meta-programming and domain engineering. It provides a virtual machine, compiler, and runtime library that make it possible to efficiently develop, debug, and run programs based on XPL (eXtensible Programming Language)

We only use the mailing list features of SourceForge. Everything else is at http://factorcode.org/

MANOOL is a practical, homoiconic, dynamic, multiparadigm general-purpose programming language with a functional core. It has high expressive power but is implemented in less than 10K LOC of optimized, idiomatic C++11 for native run-time environments. MANOOL is meant to compare and compete directly with Python, PHP, Ruby, Perl, and Tcl, although incidentally it has some combination of unusual features. Example: {{extern "manool.org.18/std/0.2/all"} in WriteLine[Out; "Hello, world!"]} Explicitly stated design priorities of MANOOL: 1. implementation simplicity; 2. expressive power, usability, and general utility, attention to syntax and semantics details; 3. correctness, security, and overall quality of implementation, run-time reliability; 4. run-time performance and scalability; 5. consistency, completeness, orthogonality of features, and language elegance, conceptual economy and purity. MANOOL strives to satisfy all of the above goals, better than existing alternatives!

xBaseScript (PP.exe) is an open source enhanced Clipper compatible Pre-Processor, DOT Prompt Environment, and Clipper/xBase Script Engine.

Kayacc is an alternate name for the TOMBO project. I am in the process of updating the Tombo project page with version 2.1.0. Please download Tombo2.1.0.tar.gz from the Files tab. Tombo is a compiler generation toolkit for constructing compilers and interpreters. It includes a BNF compiler that generates parsers for context free grammars, and a class library to support compiler development. The class library supports symbol tables, Unicode text manipulation, reserved word mappings, and translating between Unicode and byte oriented encodings. Tombo is an alternative for lex, yacc and Bison tools. Source can be browsed in git/code repository or src directory. Send e-mail to tombo@gekkoware.com for support

Generate a parser at runtime from a collection of C++ objects. Concisely state a parser specification in ordinary C++ code. Learn from a parser generator with an object-oriented design.

ESELC is a interpreter for the Easy Stack Environment Language (ESEL). It is written in ISO C++.

Erc is an interpreted link-oriented language. Majic is a java-based interpreter for Erc, and Majicc is a c++ based compiler for Erc which uses the Majic libraries.

FIJI the ForthIsh Java Interpreter is an interactive environment with a procedural syntax similar to the Forth programming language. FIJI can load, introspect, and execute Java classes and methods. FIJI's main use is for unit and component testing of Java.

Galliwasp is an answer set programming (ASP) system utilizing a unique top-down, goal-directed execution method.

Compiler optimization for code that AI generates, reuses similar substrings of code to exponentially reduce the Big-O of compile. At runtime, CodeTree objects breed, rename vars, mutate code and run it instantly. For any realtime compilable language.
