The browser build stamped each snapshot of the Web Locks held with Date.now() and judged its age against Date.now(). After the system clock was set back, an old snapshot read as fresh, so a tab could report no lock on an area another tab still held. Snapshots are now stamped and aged with vectorcraft_ui_egui::now_ms(), and a snapshot stamped later than now is not trusted.

//! VectorCraft in the browser.
|
|
//!
|
|
//! Runs the same [`vectorcraft_ui_egui::VectorcraftApp`] as the desktop app through eframe's web
|
|
//! runner (wgpu: WebGPU where available, WebGL2 otherwise). Build with `trunk build --release`
|
|
//! from this directory; see `docs/development.md` ("Web build").
|
|
//!
|
|
//! Differences from the desktop app:
|
|
//! - no TCP control server (browsers can't listen on sockets);
|
|
//! - File → Open uses the browser file picker; bytes arrive asynchronously through
|
|
//! `Services::picked_inbox`;
|
|
//! - Save / Export trigger a browser download;
|
|
//! - dropped files are read asynchronously by `web::WebShell` and delivered through the inbox;
|
|
//! - pen and finger input is read from Pointer Events by `pencil` (Apple Pencil pressure and
|
|
//! hover, palm rejection, fingers navigate once a pen has been seen, the pen's eraser end
|
|
//! selects the Eraser tool);
|
|
//! - a Cmd or Ctrl chord the keymap binds runs its command, not the browser's own action as well
|
|
//! (`Cmd+=` zooms the canvas, not the page; `Cmd+Z` undoes in the document) (`keys`).
|
|
//!
|
|
//! URL query flags: `?webgl` forces the WebGL2 backend instead of WebGPU; `?lang=es` (any
|
|
//! language code) stands in for the browser's languages when the interface language is Automatic.
