Ian Chamberlain 971775e3b2 gpui: Implement audible system bell (#47531) ... Relates to #5303 and https://github.com/zed-industries/zed/issues/40826#issuecomment-3684556858 although I haven't found anywhere an actual request for `gpui` itself to support a system alert sound. ### What Basically, this PR adds a function that triggers an OS-dependent alert sound, commonly used by terminal applications for `\a` / `BEL`, and GUI applications to indicate an action failed in some small way (e.g. no search results found, unable to move cursor, button disabled). Also updated the `input` example, which now plays the bell if the user presses <kbd>backspace</kbd> with nothing behind the cursor to delete, or <kbd>delete</kbd> with nothing in front of the cursor. Test with `cargo run --example input --features gpui_platform/font-kit`. ### Why If this is merged, I plan to take a second step: - Add a new Zed setting (probably something like `terminal.audible_bell`) - If enabled, `printf '\a'`, `tput bel` etc. would call this new API to play an audible sound This isn't the super-shiny dream of #5303 but it would allow users to more easily configure tasks to notify when done. Plus, any TUI/CLI apps that expect this functionality will work. Also, I think many terminal users expect something like this (WezTerm, iTerm, etc. almost all support this). ### Notes ~I was only able to test on macOS and Windows, so if there are any Linux users who could verify this works for X11 / Wayland that would be a huge help! If not I can try~ Confirmed Wayland + X11 both working when I ran the example on a NixOS desktop Release Notes: - N/A		2026-04-01 02:50:01 +00:00
