Open Source C++ Interpreters

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.

Objeck is an object-oriented programming language with functional features. Objeck emphasizes, expression, simplicity, portability, and scalability. The programming environment consists of a compiler, virtual machine, and command line debugger with IDE plugins.

Very high level modular programming language with multiple dispatch, object-oriented programming, functional closures and goal-directed programming.

The robot knows commands step, left, right, pick, put, paint, delay. You can use integer variables, multidimensional arrays, arithmetic and logic operators, procedures and functions with parameters. The application includes a text editor, compiler, interpreter and debugger.

version 5 in C++ WinAPI, for compiler MinGWx64 is manually rewrited from JavaScript no GL version in Notepad++ ( https://sourceforge.net/projects/karel-3d/ ). ZIP include source code and just one EXE file without install to direct Run KAREL-3D ( tested on Win10 x64 and Win7 x64 without MinGW compiller [ not need .dll ] ) Objects: brick, wall, mark, bridge. In Karel, currently can not be use Load or Save ( use Ctrl+C, Ctrl+V between the editor and Notepad ) Tip for Karel: Type command: FAST before commands for demonstrating maximum performance. First KAREL-3D is created in 1986 after Karel the Robot, in Slovakia ( before Czechoslovakia ) on 8 bit microcomputer PMD 85-2 for school kids to learn algorithm and what is programming, teach know how to solve a logical problem, like Spock and his children from the planet Vulcan ( live long and prosper ). because it's fun Actual WebGL version: https://sourceforge.net/projects/karel-3d-webgl/

Gura is a programming language that features "implicit mapping" and "member mapping", which can handle multiple data in lists and iterators at any one time.

a new concept for programing: new syntax and a new way of coding source files. not bytecode or any typical implementation for vm. in fact, it encodes functions and keywords for a smaller code, which is good for small devices and embebbed devices. small code, small size, RUN faster.

Development environment for Karl Fant's Invocation Programming Language described in "Computer Science Reconsidered" (Wiley, 2007)

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!

Cartesian is a pure functional programming language, wrapped in an imperative and object oriented layer. The main goal is to separate both worlds and to have some very clean and well defined interfaces. This project is the reference implementation of the language, as an interpreter. The interpreter's goal is not performance.

Wirthless is a language developed for ThyLordRoot's "Developing A Programming Language" lecture series on Youtube. Wirthless is a simple language with no particular goal of fitness for use, but designed as a trivial language to demonstrate concepts related to language theory and programming languages. This project archives code developed over the course of the lecture series as well as lecture slides.
