Artspeak : creative coding platform

Use it at https://mrdaybird.github.io/artspeak/

Artspeak is a language and a platform, where you can create art in a REPL-like format. It is written in C++ and can be used natively on your computer as well as on the web.

What?

• At this point, it is basically a clone of tixy.land
• In future, the idea to extend features and "try" to reach something like shadertoy, but staying minimal at its core.
• But unlike tixy.land, it ships its own language and interpreter! What does this mean?
  1. This means it is not dependent on the browser and javascript.
  2. I have full control on langauge design and features.
  3. Better performance. (potentially?) Though, it does not mean much for now!

Syntax

You have four read-only variables.

• t: time
• i: index
• x: x-axis position
• y: y-axis position

You can write an expression with these four variables and provided math functions.

Supported functions and operations:

• +, -, *, /, **(power), sin, cos, tan, sqrt

Upcoming: abs, random, and more...

How?

The language at its core is a simple bytecode interpreter written in C++. Thus each time you write a expression, it is compiled to stack-based bytecode, which is then evaluated on given time value and i,x and y attributes of each canvas element. (Canvas here refers to the animation/graphics that you see.) The canvas is created using raylib. All this is made available to the web using wasm and emscripten!

Progress:

• For desktop -> write a language from scratch and use raylib for graphics
• For web -> compile to javascript and wasm using emscripten
• Add more functions and operations

Using artspeak

(to be updated)

For now, I have locally tested only on my machine(linux)

Dependencies(no need to install, cmake installs them for you): fmt, raylib

To build for desktop:

	cmake -S . -B build -G Ninja -DPLATFORM=Desktop
	cmake --build build

Then, run ./canvas and have fun!

To build web version, you will need emscripten/emsdk:

	emcmake cmake -S . -B build-web -DPLATFORM=Web -G Ninja
	cmake --build build-web
	cp build-web/web/* docs/

Then you can test using emrun docs command or use python3 -m http.server 8080 command inside the docs folder.
