Explainer No information provided Specification https://github.com/gpuweb/gpuweb/pull/5268 Summary Allows a single assignment statement to update multiple components of a vector in the WebGPU Shading Language (WGSL). Developers can use swizzle syntax on the left-hand side of an assignment rather than reconstruct entire vectors or assign components individually. This reduces boilerplate, improves shader readability, and aligns WGSL with other common shading languages. Blink component Blink>WebGPU Web Feature ID webgpu Motivation Allows a single assignment statement to update multiple components of a vector in the WebGPU Shading Language (WGSL) to reduce boilerplate, improve shader readability, and align WGSL with other common shading languages. Initial public proposal No information provided TAG review No information provided TAG review status Pending Goals for experimentation None Risks Interoperability and Compatibility This feature has been approved in W3C GPU for the Web WG meetings including participants from Safari and Firefox. Gecko: No signal (https://github.com/gpuweb/gpuweb/pull/5268) Feedback indicated via WebGPU standardization process. WebKit: Positive (https://github.com/gpuweb/gpuweb/pull/5268) Specification approval constitutes a positive signal. Web developers: Positive (https://github.com/gpuweb/gpuweb/issues/737) The spec issue requesting this feature is one of the top 10 most thumbs-upped issues in the gpuweb repository. Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? No information provided Debuggability No information provided Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No All platforms will eventually have support. Will immediately be available on Android, Android WebView, ChromeOS, Mac, and Windows, where hardware support is available. Linux is planned to have WebGPU support in the future, so this feature will become available when WebGPU does. Is this feature fully tested by web-platform-tests? Yes WebGPU/WGSL have a conformance test suite (https://github.com/gpuweb/cts) that is regularly pulled into Chromium and part of the testing of Dawn/Tint in Chromium. While the CTS can be embedded in WPT, the WebGPU team opted to keep it separate in Chromium testing to use a customized harness for robustness and performance. https://github.com/gpuweb/cts/issues/4579 Flag name on about://flags No information provided Finch feature name UnsafeWGSLFeatures Rollout plan Will ship enabled for all users Requires code in //chrome? False Tracking bug https://issues.chromium.org/433787057 Estimated milestones No milestones specified Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
