PyWry: Cross-Platform Rendering Engine in Python
- nycdatasci 5mo agoInteresting project. The examples page needs screenshots.
- simonw 5mo agoOne-liner with uv to try this out: uv run --with pywry python <<'EOF' app = PyWry() def on_button_click(data, event_type, label): """Called when the button is clicked.""" app.emit("pywry:set-content", {"id": "greeting", "text": "Button was clicked!"}, label) html = """ <div style="padding: 20px; text-align: center;"> <h1 id="greeting">Click the button below</h1> <button onclick="window.pywry.emit('app:button-click', {time: Date.now()})"> Click me! </button> </div> """ app.show( html, callbacks={"app:button-click": on_button_click}, ) app.block() EOF Looks promising. Here's a screenshot: https://gist.github.com/simonw/092386c894d3a0deb2572f3155552183?permalink_comment_id=6123288#gistcomment-6123288 https://gist.github.com/simonw/092386c894d3a0deb2572f3155552...

- swiftcoder 5mo agoMaybe I'm an old fart, but "rendering engine" used to mean 3D graphics. This is actually a cross-platform UI toolkit? Or rather a web toolkit than can be deployed to desktop via Tauri?
- tuvix 5mo agoYou’re not alone I was assuming it was 3D graphics as well. Disappointed to see, according to other comments, it’s a wrapper around python bindings to Tauri
- yunruse 5mo agoI thought so too at first. It is definitely something interfaced on top of Tauri[0] with some sort of 'server-side logic' framework[1]. But looking at Tauri's site, it is really hard to disentangle if PyWry is a binder about WRY[2] or not. "OS-efficient cross-platform HTML-based UI toolkit" is a great technological thing, but neither PyWry and Tauri's sites make that clear, or meaningfully advertise what they do. Which is a shame, because there is myriad software which might benefit all to use this. [0] Tauri is akin to Chromium, I think? https://tauri.app https://tauri.app [1] and also a rather large amount of LLM integration; the source for PyWry has a whole section for Claude bindings [2] the Webview Rendering librarY (WRY) used in Tauri https://github.com/tauri-apps/wry https://github.com/tauri-apps/wry
- swiftcoder 5mo ago> Tauri is akin to Chromium, I think? Yeah, Tauri is for shipping web apps as desktop apps - basically an Electron replacement. Its main selling point is that it uses the system web view on Mac/Windows, so it doesn't have to bundle most of Chromium with every app.
- simonw 5mo agoI had a poke around in the wheel and it looks like a lot of the heavy lifting is done by this 30.8MB binary file: pywry/_vendor/pytauri_wheel/ext_mod.cpython-310-darwin.so Looks like that's vendored from this project: https://github.com/pytauri/pytauri https://github.com/pytauri/pytauri
- IshKebab 5mo agoIt's Electron! (Basically; I know it technically isn't.) If you're going to use Tauri I dunno why you wouldn't just use Typescript. Why bring Python into things?
- simonw 5mo agoBecause you like working Python more than typescript, and/or there are existing Python libraries you want to use that have no good typescript equivalent.
- rirze 5mo agoThis feels like a Rube-Goldberg kind of integration. I would love to know if there's an actual use for this opinionated stack, because I would've never guessed it.
- firebot 5mo agoSite is rendered extremely poorly on Firefox Mobile.
- wisemanwillhear 5mo agoInteresting, I've been using Flet for my projects lately, and I've been very happy for desktop environments. Never tried it on web and phone platforms, but Flet has similar run-everywhere marketing which originally drew me in. Anyone know how PyWry differs from Flet?
