🌕 網路開發者的自虐指南
➤ 從 C 程式碼到網頁應用程式：一場充滿挑戰的旅程
✤ https://sebastiano.tronto.net/blog/2025-06-06-webdev/
本文探討了將 C/C++ 程式碼轉換為可在網頁瀏覽器中運行的 WebAssembly 的過程。作者分享了將一個 Rubik’s cube 最佳解算器轉為網頁應用程式的經驗，並詳細說明瞭設定環境、編譯程式碼、處理多線程、以及如何與 JavaScript 和 HTML 整合。文章坦承此過程複雜且令人沮喪，但最終成功並帶來了寶貴的學習經驗。這篇文章更適合有 C/C++ 基礎，想將程式移植到網路的開發者，而非尋找標準網路開發教學的初學者。
+ 這篇文章很誠實地描述了 WebAssembly 開發的困難，讓我對這個技術有更深入的瞭解。
+ 雖然過程聽起來很複雜，但如果能將現有的 C++ 程式碼移植到網路上，將會非常方便。
#網路開發 #WebAssembly #C++ #Emscripten
#emscripten
seems I somehow got #MicroHs #Haskell interpreter compiled and working in a browser using #Emscripten #WebDev
used a require.js I found online (from Tarp https://pixelsvsbytes.com/2013/02/js-require-for-browsers-better-faster-stronger/ ) and slighly patched for my use case / url layout, and some minimal #NodeModules folder (npm install --save path) with custom symlinks inside to choose the browser js.
the HTML from Emscripten is patched lightly to add the require script and a couple of require() calls. the standard library is included with preload file; the total size of the served folder is about 3.5MB.
the usability is terrible (have to enter input in a modal form with no history or completion etc, output goes to browser console) but it's a start!
I released an Emscripten port of Dawn, which is an open-source and cross-platform implementation of the WebGPU standard.
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 .

I've ported Empty Clip, a 2D role-playing shooter #game from 2006, for the web with #Emscripten. Needs WebGL2!

My latest contribution to the Emscripten project is now live with 4.0.4: a contrib port to easily embed Lua in any project

Released emscripten-glfw 3.4.0.20250209:
* Added support for touch (mobile)
* Added support for wasm64 (-sMEMORY64 Emscripten option)

Link📌 Summary: 本文介紹了一個名為 LinuxPDF 的專案，該專案使得 Linux 系統可以在 PDF 檔案內透過 RISC-V 模擬器運行。此技術運用到 PDF 檔案格式中所支持的 Javascript，並透過 Emscripten 將 C 程式碼編譯成 asm.js，進一步載入修改過的 TinyEMU 模擬器。雖然在 PDF 中運行 Linux 存在性能問題，但這一創新仍能展示 PDF 檔案的多元性及其潛力。
🎯 Key Points:
- LinuxPDF 專案能讓 Linux 在 PDF 內運行，基於 RISC-V 模擬器。
- PDF 格式支持 Javascript，但瀏覽器的 API 限制了其功能。
- 提供了 32 位和 64 位的根檔案系統，默認使用 32 位版本。
- RISC-V 模擬器運行速度較慢，Linux 核心啟動時間約需 30-60 秒。
- 使用者可透過克隆專案並運行指定指令來建置系統。

📢 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
```
I've ported Atomiks, remake of a classic puzzle game from 1990, for the web with #Emscripten. Even mobile friendly!
A port of Doom (1993) that runs inside a PDF file
https://github.com/ading2210/doompdf. Made possible through asm.js and #Emscripten. 🤯
I have a new #programming playground: #WASM with #Emscripten
https://emscripten.org/
I explored this platform some time ago, but had no practical use for it.
But #HTML5 #canvas elements can act as a "screen" for stuff generated or managed in c or #cpp.
Posting user events to a "native" WASM worker and posting back images to the browser's thread makes the browser a virtual machine for classic C programs.
It's not very performant, but sufficient.
And it's pure fun to see that it just works 😁
I've ported Simple Sokoban for the web with #Emscripten. Mobile friendly!
I've ported Starfighter, a side-scrolling shoot 'em up space game for the web with #Emscripten. Even (somewhat) playable on mobile!
I maintain the #Emscripten port of Brogue, a minimal roguelike game, now.
I've ported Powermanga, an oldschool shoot 'em up, for the web via #Emscripten. Works also on mobile!
I've ported Help Hannah's Horse, a Pacman clone with ghosts, music and powerups for the web with #Emscripten. Even mobile friendly!
I've been experimenting with emscripten lately, so I created a skeleton cmake project that prepares emsdk and use it to compile C code instead of using a C compiler #cmake #emscripten #webassembly https://github.com/pvmm/skeleton-emsdk-cmake
