WebAssembly WASM

Open-source WebAssembly projects categorized as WASM
Edit details

WebAssembly (abbreviated WASM) is a binary instruction format for a stack-​based virtual machine. WebAssembly is an open standard that defines a portable binary-code format for executable programs, and a corresponding textual assembly language, as well as interfaces for facilitating interactions between such programs and their host environment.

    • Project mention: Show HN: TinyWasm – A tiny WebAssembly Runtime written in Rust | news.ycombinator.com | 2024-03-07

    Super nice project! I also spent the last month writing a WASM interpreter ( https://github.com/rrampage/wart ) using Java 21. I started it as an excuse to try out the pattern matching in switch / sealed classes in Java. It kind of snowballed in scope and can now run Doom and Waforth ( https://github.com/remko/waforth )! Have not yet tried compiling it to WASM and running it as a meta-circular interpreter.

    I went through the same exercise implementing trig functions for scheme in webassembly...

    It was a rabbit hole for sure

  • wasm-snake

    Classic Snake in direct WebAssembly

    • Project mention: Classic Snake in Direct WebAssembly Text | news.ycombinator.com | 2024-03-04

    All of the game graphics, state and logic are written in WebAssembly Text. The host environment (Javascript) is responsible for:

    Game tick loop

    User input

    Providing characters "0123456789GAMEOVER" byte data on game startup

    Blitting the pixel buffer to the display with WebGL2

    The game uses 3 virtual pages of memory (64kb each) for a total of 192kb. Within those exist the pixel buffer contents, the characters data and snake positions. For more detailed breakdown you can check src/snake.wat.

    The memory is shared between WASM and JS. On each game tick, the pixel buffer region of the memory is transferred to a WebGL2 texture, uploaded to the GPU and blitted to the screen.

    For more info you can refer to the repo - https://github.com/gnikoloff/wasm-snake

  • wasmrogue
