#emscripten — Public Fediverse posts

Oh, look! Another attempt to solve the monumental crisis of handling tarballs—this time with #WebAssembly and a sprinkle of #Emscripten magic. 🙄 Instead of just extracting a file like a normal person, let's generate an "index" to mount things because who doesn't love an overengineered solution to save a few bytes? 😂

Just posted a new devlog for our C-based web engine, Archimedes!

It's been a long road from Pygame to a custom C/Emscripten stack. I'm breaking down the architectural hurdles of moving away from our Daedalus library and how my collaborator @smattymatty has been stress-testing the engine with a vampire survivors clone and recent game jams.

To celebrate the progress, I've rewritten my old ( and very broken ) Game of Life simulator from the ground up. It's a great feeling to see a legacy project running smoother than ever on new, custom-built foundations.

Check out the devlog: https://jake-ster.itch.io/game-of-life/devlog/1462381/remaking-my-old-game-of-life-clone-with-archimedes

Long shot, but is there anyone here who has used SDL3 and Emscripten or is familiar with building Emscripten from source?

I had to get SDL3_TTF from a PR, and managed to build it with embuilder but so far when I try to build with -sUSE_SDL_TTF=3 it doesn't seem to acknowledge the option and if just complaining that it can't find SDL3/SDL_ttf.h

What am I missing?

(also if you don't know, sharing is caring)

emsdk-env makes public.

This is a Vite plugin that automatically downloads and manages the Emscripten SDK, and makes it possible to automatically build WASM C/C++ code in your project.

With this plugin, you can easily set up a WASM C/C++ development environment in your Vite project.

Using Emscripten to Run C Code in Mendix

#Mendix #Emscripten

https://medium.com/@ockert8080/using-emscripten-to-run-c-code-in-mendix-b74c4df10b3e

I recently gave a makeover to the project page for the first video game I ever made: https://fietkau.media/revelation_mentis

The game itself is a small adventure/exploration game for DOS. It's not much to look at. But I touched up the game itself and the web-based player to make it a lot more approachable:

- Full English translation
- Nicer menu navigation
- Touch controls on mobile! 🤯
- A cute little optional CRT filter
- Updated #DOSBox and #emscripten, it no longer hangs the page on load for a second

I tried pulling the procedure to change the main engine loop out of WASM's control (https://codeberg.org/indigoparadox/maug/commit/ce442fe911da82bc8856aeb30857ddad92c75012) but #numoon is still, like... skipping every other tick? Or something? Every other in-game script instruction seems to be ignored? And mobile animation isn't happening? Almost like it's just not showing those frames?

But only in #WASM with #emscripten! The #SDL code on native Linux works perfectly!

*Extremely* frustrating...

Question on #licenses: Take an #LGPL licensed library written in C, compile it to JavaScript with #emscripten, and bundle it into a JavaScript app. The JavaScript app has to be LGPL licensed because the dynamic linking exception doesn't apply.

Same LGPL library, build a #NodeAPI module that statically links against it, and use that in a JavaScript app. The NodeAPI code would be LGPL'ed since it's statically linked, but would the #JavaScript code be fine since node loads the module dynamically?

After again struggeling with #emscripten and the wait4 / wait3 #syscalls, and stumbeling across my 1year+ old bug report on that matter, I just said "Fine, I do it myself" and added the two missing c sources to the build process of emscripten's #libc build xDDDDDD Works flawlessly lmao

Today I'm wondering how I could get the new Python 3.13 REPL working in WebAssembly in the browser. 🤔

xterm-pty for xterm.js looks possibly helpful, but I'm unsure how to use it: https://github.com/mame/xterm-pty

I'm also wondering what CPython will need to be configured in its environment to properly trigger the new REPL.

I'm a TTY novice and definitely feel in over my head with this train of thought. 😅

Playing with libav.js [1] (#ffmpeg in #javascript through #emscripten)

TIL about "async functions" [2]. Seems like moving from "normal" to "async" is a one-way street - normal functions can be easily called in an async context, but it looks like there's no way to get the value of an async function in sync context.

Yes, I can ".then(...)" on the return value, but then I'm back in callback hell and no longer "sync", am I...

Proof-of-concept project, showing that it's possible to run an entire Large Language Model in nothing but a #PDF file.

It uses #Emscripten to compile #llama.cpp into asm.js, which can then be run in the PDF using an old PDF JS injection.

Combined with embedding the entire #LLM file into the PDF with base64, we are able to run LLM inference in nothing but a PDF

Запуск Linux внутри PDF

По мнению некоторых пользователей, PDF — простой формат для обмена документами. На самом деле это очень сложный стандарт, который поддерживает выполнение практически любого кода. Неудивительно, что в прошлые годы энтузиастам удалось успешно запустить Doom внутри PDF и провести ряд других интересных экспериментов. Оказалось, что на этом возможности движка по рендерингу PDF не ограничиваются. Он способен запустить даже эмулятор полноценного процессора, а в нём — целую операционную систему .

Happy to announce the release of WebGPU Shader Toy.

You can try it in your browser: https://pongasoft.github.io/webgpu-shader-toy/

My WebGPU Shader toy is progressing quite nicely...

* Load external shaders
* Drag and drop
* Show Inputs value live
* Show errors
* Store current window sizes (local storage)

Very early prototype of my attempt at building something like a shader toy for WebGPU in the browser.

Technologies used:

* emscripten (c++) for the compiler
* contrib.glfw3 for the GLFW implementation (multi / resizable windows)
* ImGui in one window
* Straight WebGPU / Fragment shader in another (using webgpu_cpp.h)
