v0.1.30

bezel-browser, a platform webview placed in a gpui window: WKWebView on macOS, WebView2 on Windows, webkit2gtk on Linux under X11, and an iframe on the web build.

New

• bezel-browser (browser) holds WebView, an entity whose element places a native webview at its bounds in every frame it is painted and parks it, hidden and moved off-window, in every frame it is not. A parked page stays loaded. Nothing gpui paints can cover the page, and content masks do not clip it.
• WebView::load, back, forward and reload; location, title and is_loading as the page last reported them. WebViewEvent carries Location, Title (on change only) and Load(LoadState), taken from the page rather than from what it was told to load.
• WebView::eval runs a JavaScript expression in the main frame and decodes its value from JSON, with a timeout. EvalError says why there is no value.
• WebView::with_user_agent replaces the user agent the page is built with. On macOS the default is Safari's, with the installed Safari's version.
• Keyboard focus follows gpui focus both ways: focusing the view's handle gives the page keys, a press in the page focuses the handle, and blurring or parking hands keys back to gpui. On macOS cmd-c, cmd-x, cmd-v, cmd-a, cmd-z and cmd-shift-z reach the page in the WebView key context.
• On macOS the page sets the cursor over itself; gpui's cursor rects are off while the pointer is inside it.
• Linux needs gpui on X11 and paints nothing under Wayland. It initializes GTK and pumps its events on a gpui timer unless the host already initialized GTK.
• browser::Frame, on the web build only, puts an <iframe> beside gpui_web's canvas at the element's bounds, hidden when not painted and removed on drop. It reports nothing about its page.
• The gallery's Browser page: an address field over a WebView, over a Frame on the web build. apps/browse is a Safari-shaped demo browser with tabs, a unified toolbar and a favorites start page.
