PyWry: Cross-Platform Rendering Engine in Python

  One-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/092386c894d3a0deb2572f3155552...

  This 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.

  I 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

  Interesting project. The examples page needs screenshots.

  Maybe 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?
