L5: Creative Coding in Lua

L5 is a fun, fast, cross-platform, and lightweight implementation of the Processing API in Lua. It is a free and open source coding library to make interactive artwork on the computer, aimed at artists, designers, and anyone that wants a flexible way to prototype art, games, toys, and other software experiments in code.

If you've used Processing or p5.js to do creative coding, you will be easily able to use your knowledge to get started. If you're new to creative coding, check out the tutorials and other documentation.

L5 is designed to work cross-platform, including on desktop, phone, and tablet. Beyond running fast on modern machines, L5 is optimized for older and lower-powered devices, minimizing resource usage to keep creative coding accessible to everyone. This helps with our goal of building resilient, long-lasting software projects. L5 is built in Lua, a robust but lightweight, long-running, lightning-fast, extensible language.

L5 is free and open source, with the latest library always available for download along with the latest documentation.

Three steps to get started using L5:

1. Install Love2d for your computer system
2. Download and unzip the L5-starter folder (contains L5.lua file and main.lua where you write your code)
3. Drag your L5-starter folder onto the Love application to run it. Edit main.lua to write your own programs. Save and drop onto Love to run them. Or run them from your favorite code editor or the command line. (See documentation for more info on additional options)
