Make the loop public and let the display drive it

2026-10-15T17:38:14+00:00

An application that has its own descriptors and timers needed a second loop next to yasl's, and could not see yasl's key-repeat timer, clipboard pipes or reconnect timer. Now there is one wait: the application owns a yasl_loop, and yasl_init can run the display on it. - Public yasl_loop_*: descriptors, timers and signals. Descriptor callbacks return void. Timer IDs are 64 bits and never reused; a zero delay runs in the next step. A nested step or run fails with EBUSY, a step off the loop's thread with EPERM, and a quit made before a run ends it at once. An interrupted wait keeps its deadline. Creating a loop fails when it cannot make its wake pipe. - The display drives the loop through prepare, wait and check hooks instead of wrapping its step. Wayland finishes its read before any callback runs, so loop callbacks may create surfaces and do roundtrips. Readiness (queued events, an owed REFRESH) is derived in the step, so the wait never blocks over pending work. A draw that cannot proceed for want of a buffer is no longer counted as work. - yasl_init takes struct yasl_options. With loop and on_event, each step delivers events to on_event and yasl_wait_event fails with EBUSY. EALREADY only for the same options, EBUSY for others. - yasl_surface_request_frame: a REFRESH once the window can show a new frame, for pacing animation. - DISPLAY_LOST reports whether the display reconnects. Pull waits still fail with ENOTCONN after a final loss. - Events pushed from another thread wake the loop. Co-Authored-By: Claude Opus 5.5

Wayland: fix GL thread races, reconnect ordering and sizing bugs

2026-10-14T11:17:37+00:00

- GL swaps on a rendering thread no longer touch frame callbacks or presentation feedback. They set a per-surface flag and wake the loop; the owner thread arms both at its next flush and commits, so the frame callback fires without waiting for the application's next swap. - Clear the offline flag only after the reconnect rebuild succeeds, and not when the connection was lost again during it. - make_current fails with ENOTCONN for a window without a context. Detaching is a no-op when nothing is current or the EGL display is gone. - Window move, resize, window menu and drag start need a pointer button or tablet tip that is still held; otherwise they fail with ESTALE and use that press's serial. Popups fail with ESTALE without an input serial and with ENOTCONN while the display is lost. - An oversized device size shrinks to the buffer limits, keeping the aspect ratio, instead of closing the window. - FIXED_SIZE windows pin xdg min and max on every set_size. The 64px minimum applies only to compositor-suggested sizes, not to application sizes. - The keyboard-enter serial becomes the input serial. Clipboard copy with no keyboard focus fails with ESTALE. - Relative-pointer windows relock after a reconnect rebuild. - errno: EBUSY for an active drag, ENOTSUP for place_under_pointer and for GL without EGL, EINVAL for drag carry without a drag. - Default window title and app ID are "YASL". - Pointer motion and button events carry unrounded device-pixel positions in precise_x/precise_y with precise_position set.

Simplify the public API into one dense header

2026-10-14T10:56:48+00:00

yasl.h now holds everything except Vulkan: 45 functions instead of 62, and three installed headers instead of ten. - One constructor: yasl_surface_create takes CPU, GL or NATIVE, with zero-initialized GL options meaning 3.2 core, RGBA8, D24S8. - Events carry action, mods, x, y and text at the top level; pen positions are now logical like pointer positions. - yasl_cpu_pixels/yasl_cpu_present draw into one persistent canvas, cutting three full-frame copies per frame. - yasl_surface_get_info, yasl_surface_request, YASL_CURSOR_LOCKED, yasl_surface_set_text_input, yasl_surface_begin_move_resize and yasl_surface_get_native replace groups of narrower calls. - Interactive calls drop the decorative trigger event argument. - yasl_wait_event returns 0 only on timeout or yasl_wake, the refresh callback runs only in native modal loops, focus loss sends INPUT_RESET, and a lost event no longer fails every later wait. - Unsupported operations and bad arguments report ENOTSUP and EINVAL instead of EIO; the keycodes header no longer needs C23. - The shared library gets a versioned SONAME and version macros.

Reconnect to a restarted Wayland compositor

2026-10-13T20:52:22+00:00

Windows now outlive the compositor. On connection loss YASL sends DISPLAY_LOST instead of closing every window, retries the connection on a loop timer, rebuilds each toplevel with its title, size, state and GL context, and sends DISPLAY_RESTORED. CPU windows keep their pixels; GPU renderers drop Vulkan surfaces and GL objects on loss and rebuild them on restore. - Free the dead connection's objects on the next wait, after the application has released GPU objects built on them. - Report a lost connection as an event rather than a failed wait. - Refuse window and Vulkan surface creation while offline with the new YASL_ERROR_DISCONNECTED. - Close popups, cancel drags and fail pending clipboard requests on loss. - Print only protocol errors, not ordinary disconnects. - Examples survive a restart; game.c rebinds its GL context. - Add an end-to-end test that kills Weston under CPU, GL and Vulkan windows and requires them to recover.

Simplify the public event and CPU API

2026-10-13T20:41:31+00:00

Applications now need far less ceremony: hello.c is a 20-line loop that handles REFRESH, CLOSE and QUIT and draws into the surface's own pixels. - Fold GEOMETRY, STATE and FOCUS into one WINDOW event carrying size, scale and state; unchanged values send nothing. - Guarantee REFRESH once a window has a size and after every resize, never at size zero. - Merge DROP_HOVER into DROP with over/leave/data actions and give drag and drop actions enums. - Keep event strings valid until the next wait and drop yasl_event_release; empty or failed waits report NONE. - Replace copy-in presentation with a lent pixel buffer: yasl_cpu_pixels and yasl_cpu_present. - Remove yasl_poll_event, yasl_cpu_read_pixels, unused event fields and comments that restated names. - Wayland: resize floating windows in request_size instead of reporting it unsupported, and stop marking new GPU surfaces as Vulkan so yasl_vulkan_create_surface no longer fails with NATIVE_WINDOW_IN_USE. Also includes the in-progress public API refactor that was uncommitted in the tree (removal of the app/loop layer, new surface, GL and Vulkan entry points). Co-Authored-By: Claude Opus 5.5

Add desktop services: open URI, notify, appearance, bell, and paths

2026-10-13T14:05:59+00:00

wsap_term keeps per-platform code for opening links, notifications, the bell, high-contrast detection, the executable and bundle paths, and the default locale. These now live behind . On Linux, src/platform/freedesktop serves both backends. Opening a URI runs xdg-open from PATH through a double fork, so the opener gets default signal dispositions, an empty mask, a new session, and none of the application's descriptors. Notifications and the Settings portal use the session bus through libdbus-1, an optional dependency behind -Ddbus. Appearance falls back to GTK_THEME without a portal. The bell uses xdg-system-bell on Wayland and the XKB bell on X11. Cocoa implements the same calls with NSWorkspace, UserNotifications, the effective appearance, NSBeep, the bundle, and CFLocale. That code is not built or run here; it needs a macOS check. The desktop test runs under dbus-run-session against a fake notification server and portal, and uses a fake xdg-open to check argument passing, signal state, and descriptor inheritance.

Report held pointer buttons on every pointer event

2026-10-13T13:57:59+00:00

Pointer events set button only on press and release, so wsap_term tracked held buttons itself to tell a drag from a hover. yasl_pointer_event.buttons now holds a YASL_BUTTON_BIT() mask of the buttons held after each event. The common input queue tracks it from the DOWN and UP events it queues, and clears it on INPUT_RESET and on allocation failure. Wayland also clears it on leave, since the compositor sends leave during a press only when it takes the pointer and no release follows. X11 and Cocoa keep it, because they deliver motion and the release to the pressed window after leave. Co-Authored-By: Claude Opus 5.5

Implement relative pointer mode on Wayland

2026-10-13T13:23:07+00:00

yasl_surface_set_pointer_mode(YASL_POINTER_RELATIVE) now takes a persistent zwp_locked_pointer_v1 on the surface and hides its cursor. While the compositor keeps the lock engaged, zwp_relative_pointer_v1 motion is pushed as POINTER_MOTION with pos frozen and delta in device pixels. When the lock disengages, as on focus loss, motion is absolute again with a delta derived by the input queue. The lock follows the pointer's seat: it moves to another seat when its seat loses the pointer, and is released on NORMAL and on surface destruction. Compositors without both protocols return false.
