My adventure into the marvelous world of Web Assembly
Demo

How to compile and play
- Run
./make - Open
index.htmlin your favorite (Web Assembly compatible) browser
How to generate wat (WebAssemblyText) code from Racket
- Run
racket src/game.rkt > build/game.wat
How to compile wat to wasm manually (you need the wat2wasm toolkit)
- Run
wat2wasm build/game.wat -o build/game.wasm
Motivations
Is it possible (and enjoyable) to write a game directly in web assembly's text format?
Eventually, would it be cool to generate wat from Scheme code using the Racket lang system?

Discoveries so far
- Wasm has two text formats: linear (stack machine) and S-expression style
- Writing directly in Wasm is tedious after a while (very verbose)
- I can use Racket to write my own DSL (Domain Specific Language) in order to program in a higher level language
- I can implement recurrent patterns into higher level procedures (see
for) - I can name constants and implement helpers (see
mem) - I can draw to a screen by using javascript's Uint8Array and pushing data to a canvas
- I can make a game?
