This is a Python-based online interpreter for the MATL programming language, a golfing language based on MATLAB and Octave. A live version of this application is hosted at matl.io.

The core of the application is the lightweight Python web framework, Flask. Two-way communication between the JavaScript front-end and the application is handled by SocketIO. MATL code and input arguments are submitted to the server and celery assigns the task to one of many available worker processes. Each worker process uses the octave_kernel library to communicate with an underlying Octave instance to evaluate the provided code. All Octave output from the process (including text and graphics) is streamed in real-time back to the browser via SocketIO.

Technologies:

• jQuery
• SocketIO
• flask
• flask-socketio
• celery
• octave_kernel
• Octave

The easiest way to run the application locally is to use Docker Compose which will start the web service, celery worker, redis instance, and postgres database. Prior to running docker-compose, be sure to build the local docker image:

docker-compose up --build

You will then be able to access the application at http://localhost:5000.

• Ability to run multiple test cases sequentially
• Analytics of all MATL answers on the Programming Puzzle and Code Golf Stack Exchange site including top users, top questions, and common usage patterns.
