This one's really nice.
- clear code structure and good architecture(modular approach reminiscent of Blitz but not as radical, like Blitz-lite).
- Very easy to follow the code and understand how the main render loop works:
- For Mac: main loop is at https://github.com/embedding-shapes/one-agent-one-browser/blob/master/src/platform…
- You can see clearly how UI events as passed to the App to handle.
- App::tick allows the app to handle internal events(Servoshell does something similar with `spin_event_loop` at https://github.com/servo/servo/blob/611f3ef1625f4972337c247521f3a1d65040bd56/compo…)
- If a redraw is needed, the main render logic is at https://github.com/embedding-shapes/one-agent-one-browser/blob/master/src/platform… and calls into `render`
Read the rest
of App, which computes a display list(layout) and then translates it into commands to the generic painter, which internally turns those into platform specific graphics operations.
- It's interesting how the painter for Mac uses Cocoa for graphics; very different from Servo which uses Webrender or Blitz which(in some path) uses Vello(itself using wgpu). I'd say using Cocoa like that might be closer to what React-Native does(expert to comfirm this pls?). Btw this kind of platform specific bindings is a strength of AI coding(and a real pain to do by hand).
- Nice modularity between the platform and browser app parts achieved with the App and Painter traits.
How to improve it further? I'd say try to map how the architecture correspond to Web standards, such as https://html.spec.whatwg.org/multipage/webappapis.html#event...
Wouldn't have to be precise and comprehensive, but for example parts of App::tick could be documented as an initial attempt to implement a part of the web event-loop and `render` as an attempt at implementing the update-the-rendering task.
You could also split the web engine part from the app embedding it in a similar way to the current split between platform and app.
Far superior, and more cost effective, than the attempt at scaling autonomous agent coding pursued by Fastrender. Shows how the important part isn't how many agents you can run in parallel, but rather how good of an idea the human overseeing the project has(or rather: develops).
