Sparkworks wasm

A wasm version of yumaikas' Sparkworks

Overview

The current approach is to build a small program that embeds janet and is linked to Raylib. The program loads and executes Sparkworks, a game written by yumaikas in Janet that uses Raylib via jaylib.

The program is made executable in a web browser by being compiled by Emscripten.

The goal of this demo is to produce appropriate .wasm, .js, .html, and related files and then to test their functionality via a web browser. Before compilation via Emscripten can take place, some pieces need to be prepared:

• main.c - the aforementioned small program
• janet.c + support files - for embedding janet
• libraylib.a - "HTML5-ready" Raylib static library
• resources - a directory containing Sparkworks bits

Prerequisites

• Emscripten 3.1.3 (other versions might work)
• Usual build tools
• Janet

Steps

• Ensure repository has been cloned recursively:

  git clone --recursive https://github.com/sogaiu/sparkworks-wasm
  

• For *nixen, with emsdk under ~/src/emsdk:

  source ~/src/emsdk/emsdk_env.sh
  janet build-unix.janet
  

• For Windows, with emsdk in a sibling directory of this repository (likely need to do via a Native Tools Command Prompt):

  ..\emsdk\emsdk_env.bat
  janet build-windows.janet
  

• Start a web server to serve the built files:

  For a machine with python3, that might be:

  python3 -m http.server --directory public
  

• Try out the results:

  Visit http://localhost:8000 and click on main.html
