Educational WebAssembly Project: Karel WebAssembly IDE

Hello everyone,

I’d like to share a project I recently built: *Karel WebAssembly IDE* — a
modern, browser-based educational environment to learn programming using a
WebAssembly-powered interpreter.

The IDE runs entirely in the browser, using WebAssembly to execute programs
written in a C-like educational language inspired by the classic “Karel the
Robot” exercises.

The project is based on the excellent work proposed by binji

https://github.com/binji/wasm-clang/tree/master

I tried to solve several problems related on buffering in a synchronous
loop for syncing stout with the canvas, and a lot of programming games for
learning C.


It features:

   - A WebAssembly interpreter compiled from C code
   - An interactive code editor with syntax highlighting
   - A 2D world renderer for visualizing Karel’s actions in real time
   - A self-contained environment with no server-side execution required

The project is open-source here:

And you can try the live demo here:

Any contribution from the community would be greatly appreciated.

Thanks,
GP
