Simple, kernel-only, 64bit OS, early stage. https://git.2137697.xyz/rs-dos/atom?h=qemu 2026-08-27T15:23:34Z 2026-08-27T15:23:34Z salmonik salmonik@tuta.io 2026-08-27T15:23:34Z urn:sha1:ba304898b8e177d90afb58d201b4c3dd3c927c48 rsapi: WmEvent (kind=u8 enum: 0=key, 1=mouse, 2=focus, 3=close), WmKeyKind (Char/Enter/Backspace/F1-F4/…), WmMouseEvent (x/y/buttons), WindowInfo (ptr/w/h). Five new exports: wm_create, wm_buffer, wm_flush, wm_destroy, wm_recv (non-blocking TaskMsg dispatch → WmEvent). Shell: abi_wm_* wrappers bridge rsapi types to rsnix::wm and sched::recv(); wm_recv translates TaskMsg::Key/Mouse/Focus/Close into flat WmEvent union. bins/paint: gate binary — create_window + buffer + event loop with Bresenham line drawing, color select (1-8), clear (c), F4 close. All via wm_* ABI exports. Fully migrated: date, mem, pci, cat, ls, mkdir, touch, rm, klog, info, paint (11 external binaries in /bin/cli/ + 3 gate binaries).
