Conway Life Demo

This is a reworked demonstration of WebAssembly with Free Pascal by Pierce Ng (@PierceNg), based on the original by Dmitry Boyarintsev (@skalogryz).

Running

Linux

Tested on Ubuntu 20.04. The WebAssembly binary lyff.wasm is already included in this repo. Just use a local web server to publish the content of htdocs say by using a Python 1-liner. You could also just compile webserver.lpr in this directory and run it.

To hack WebAssembly with Pascal, you need FPC for WebAssembly. To set up FPC for WebAssembly, see top-level README.

Build it:

% ./linbuild.sh

macOS

Tested on macOS Catalina. The WebAssembly binary lyff.wasm is already included in this repo. Just use a local web server to publish the content of htdocs say by using a Python 1-liner. You could also just compile webserver.lpr in this directory and run it.
