PlaySys

The Playbit System interface

PlaySys defines an OS-like computing platform which can be implemented on a wide range of hosts like Linux, BSD, Web/WASM, macOS and Windows. This is accomplished via two mechanisms:

  1. A syscall for communication between a program and its host play system. This is just a single function call and does not depend on any specific programming language.

  2. The filesystem for accessing resources like graphics surfaces and network connections. This is modeled on top of syscall operations.

Specification: spec.md

Source

  • include/playsys.h C API
  • examples/hello contains an example program
  • backends implementations of the playsys API for host platforms
    • posix C implementation of playsys functions on POSIX host's libc
    • wgpu WebGPU implementation for mac, win & linux based on Dawn
    • js JavaScript implementation for web browsers

Building

Building the "hello" example on macOS (>=10.15, x86_64) with WebGPU:

cd path/to/playsys
backends/wgpu/setup.sh
backends/wgpu/build.sh
examples/hello/build.sh -run out/hello_mac_x64

Note: If you're having issues with clang/llvm, install a non-Apple version from for example homebrew: brew install llvm.

Building the "hello" example for web browsers:

Concept

PlaySys is one step in a three-part strategy to birth a new software platform:

Step 1

PlaySys — a syscall-like API that is the interface betweet a program and the OS/environment. It is how the program percieves and experiences reality. Filesystem acts as an arbitrary extension to a minimal syscall API, which includes an io_uring-like interface. Capability based: e.g. does this system support pointer input? GPU compute? Writable filesystem?
An "OS" from a program's perspective

Step 2

Libraries to make GUI & CLI development easier on top of PlaySys.
The API from an app developer's perspective

Step 3

Implementations of PlaySys:

  • an OS using the Linux kernel providing a window manager
    An "OS" from a user's perspective
  • an implementation for web platform:
    run PlaySys programs in a web browser.
    An "app" from a user's perspective

    support for versions and aliases on find-llvm.sh

    For some package managers suck as aptitute, LLVM's wasm-ld is installed as wasm-ld-xx where xx is a version such as 12 or 13. This tweak on find-llvm.sh adds support for test paths for Linux, with and without versio numbers.

    Also, if the user does not has a command similar to clang or clang-xx, the script halts and returns an error message with an exit 1.

    changed /bin/sh to /bin/bash

    In this pull request, I propose the simple change of all /bin/sh to /bin/bash, due to problems on Linux. With /bin/bash, I'm certain that both MacOS and any Linux distribution will be able to run the helper scripts without editing them.

    Some systems do point sh to bash, but others do not.

  • Type errors in backends/js/playsys.ts

    Type errors in backends/js/playsys.ts

    Hey!

    I noticed a bunch of type errors in playsys.ts. There also isn't a tsconfig.json. Are you using Typescript through Visual Studio, rather than npm? Are the type errors something that need to be fixed? https://www.typescriptlang.org/docs/handbook/typescript-tooling-in-5-minutes.html

    I'm asking because I want to contribute. Is tackling the ts errors a good first issue? I would start by installing typescript, setting up a package.json, creating node_modules, blah blah blah. If you don't want to go down that route, but want types, an alternative might be to just write the sys calls in js, and use DefinitelyTyped or similar.

    Also, running the ./build.sh in the directory results in
