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

Wake and post to loops from any thread, and watch signals

2026-10-13T13:55:45+00:00

wsap_term runs its own eventfds to wake the loop from its pty worker and accessibility threads, and its own signalfd or self-pipe per platform. yasl_loop_kick() is now documented as safe from any thread and from a signal handler. yasl_loop_post() queues a function to run on the owning thread during a later step. yasl_loop_watch_signals() installs a process-wide SA_RESTART handler per signal that records the signal and kicks the loop, so callbacks run on the loop thread on every platform without touching thread masks. Cocoa dispatch waited only for AppKit events, so kicks, posts, and fd watches could not end an indefinite wait, and yasl_post_event() did not wake yasl_run(). While waiting, Cocoa now mirrors the loop's descriptors in a kqueue whose run loop source posts a wake event. If kqueue rejects a descriptor, the wait is bounded to 10 ms. The Cocoa change is not built or run here; it needs a macOS check. Co-Authored-By: Claude Opus 5.5

better public interface and doxygen

refactor: simplify public API and isolate native extensions

2026-10-12T05:41:51+00:00

Separate loop/timer and native interoperability APIs from the portable surface header. Unify dispatch, geometry queries, and timer callbacks; keep framebuffer bookkeeping and frame clocks private, and hide implementation symbols. Update backends, documentation, examples, and API/integration coverage. Verify exports, strict C/C++ installed consumers, and normal plus ASan/UBSan suites.
