Show HN: Compiling C in the browser using WebAssembly

• xcc

  2 270 9.6 C

  Standalone C compiler/assembler/linker/libc for x86-64/aarch64/riscv64/wasm

  Check out https://github.com/tyfkda/xcc, I've only used the native backend, but it's small and fast.

• emception

  5 304 2.9 C++

  Run Emscripten in the browser

  See: emception

• webassembly.sh

  6 290 0.0 JavaScript

  Open-source and installable PWA terminal powered by WebAssembly, WAPM, and Wasmer-JS 🖥

  

  The old https://webassembly.sh/ came a long way (and maybe also https://wasmer.sh/ but not sure).

  All you need is a virtual filesystem of some sort, a way to download, a way to upload, an editor, a compiler, and a VT100 JS library. We already have WASI for the rest.

  If the JS is too undesired, then perhaps go the old framebuffer graphics mode (e.g. a region of the WASM memory that is interpreted as an ASCII screen, or maybe even as a full bitmap buffer). Then JavaScript side just needs to forward keyboard/mouse into memory and that screen region out of memory.

• x86-64-playground

  1 104 9.5 C

  An online assembly editor and debugger for the x86-64 architecture

  Absolutely! You can even run clang in wasm targeting x86_64, and then emulate the resulting program using the blink x86_64 emulator.

  I'm working on something similar, where students can compile intel assembly and run it client-side: https://github.com/robalb/x86-64-playground

• xeus-cling

  17 3,115 4.2 C++

  Jupyter kernel for the C++ programming language

  

  Cling (the interactive C++ interpreter) should also compile to WASM.

  There's a xeus-cling Jupyter kernel, which supports interactive C++ in notebooks: https://github.com/jupyter-xeus/xeus-cling

  There's not yet a JupyterLite (WASM) kernel for C or C++.

• Theta

  1 38 9.6 C++

  θ A statically typed, functional programming language that compiles to WebAssembly

  

  This is true. In Theta (https://github.com/ThetaLang/Theta) this is exactly what we do -- no need for more than one pass for the WASM codegen.

• wasm-fizzbuzz

  6 1,506 0.0 C++

  WebAssembly from Scratch: From FizzBuzz to DooM.

  The framebuffer idea is used in this wasm doom port: https://github.com/diekmann/wasm-fizzbuzz/tree/main/doom

  WASIX already does all the other stuff you mentioned, including in the browser. The one thing it's missing is GUI, mainly because there's no standard GUI interface in POSIX.

• webvm

  30 10,699 9.5 Svelte

  Virtual Machine for the Web

  

  GCC? That's easy! :-) What about a complete system? https://webvm.io

  Shameless plug: we are hosting a WebVM Hackathon next week (11-14 October) over Discord. For more information: https://cheerpx.io/hackathon

• STC

  91 1,350 4.9 C

  A modern, user friendly, generic, type-safe and fast C99 container library: String, Vector, Sorted and Unordered Map and Set, Deque, Forward List, Smart Pointers, Bitset and Random numbers. (by stclib)

  

  I went down a rabbithole and wow.

  Found a comment from the author of https://github.com/stclib/STC apparently and then came across this example:

• p2p-webtransport

  4 164 7.0 HTML

  Interface to create and manage QUIC streams

  

  The spec is inactive, afaik, no implementations. Got it backwards, pardon, p2p-webtransport. https://github.com/w3c/p2p-webtransport

  I don't know why it's fallen off, to be honest, or what was raised against it. Highly desireable to a lot of p2p folk, a very promising webrtc datatransport replacement.

• emception

  1 4 - C++

  😱 Emscripten, but it's in your browser (by emception)

  

  It’s sadly a bit more of a proof of concept than a hackable project. The docker build in the readme did work last time I tried, and there is a demo site at https://jprendes.github.io/emception/, but I’ve failed to modify it in the past to do other things

  There is a fork at https://github.com/emception/emception that is trying to make it more production ready, but it looks like that may have stalled
