#AskFedi #c99 #gcc #raylib #emscripten

i'm making a raylib game that needs to detect whether it's the desktop build (gcc) or the web build (emscripten) in c99 code. can i use some some compiler flags or config in order to define some macro or to hardcode main function args or something of the sort?

this way i can connect the web build to the kongregate api and not do so (maybe not even include libcurl if it's a macro definition) on the desktop build. is this possible?

thanks ilyyy <3

Look, ma, I'm in the #Emscripten release notes: https://github.com/emscripten-core/emscripten/releases/tag/6.0.1. New experimental `-sCROSS_ORIGIN_STORAGE` linker flag integrating the proposed Cross-Origin Storage browser API
(https://github.com/WICG/cross-origin-storage) as a progressive enhancement for #Wasm loading on the Web target: https://emscripten.org/docs/compiling/CrossOriginStorage.html.

Как я портировал ретрошутер Redneck Rampage в браузер

Всем привет! Я решил наконец то сам сделать пост на хабре. Обычно о всех моих веб проектах и команды DosZone Team пишет здесь многоуважаемый @denis-19 , за что ему огромное спасибо! Ведь нам просто лень или не хватает на это времени. И так! После шутера Blood мне было интересно попробовать также портировать Redneck Rampage как раз на основе того, что я уже сделал. Было ошибочно так думать, потому что RR в отличие от NBlood оказался совершенно на другом движке - RedNukem, и пришлось начинать всё с нуля. Да и сложность повысилась и всё это заняло в два раза больше времени, чуть больше недели.

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.

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?

Using Emscripten to Run C Code in Mendix

#Mendix #Emscripten

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...

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 .

📢 Scaling multithreaded #WebAssembly applications with mimalloc and WasmFS, by @kripken:
https://web.dev/articles/scaling-multithreaded-webassembly-applications?hl=en. If you have a multithreaded #Wasm application that does lots of allocations or uses files, then you may benefit greatly by using WasmFS and/or mimalloc. Usage in #Emscripten:

```bash
emcc -sWASMFS -sMALLOC=mimalloc
