From 87279f6903343e621c0446b20d1e7d6a495f1125 Mon Sep 17 00:00:00 2001 From: Berke Güzel Date: Wed, 14 Oct 2026 13:56:48 +0300 Subject: Simplify the public API into one dense header 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.
