#+TITLE: QA 07 — Cursor
#+TODO: TODO | PASS FAIL SKIP

* How to run
  : emacs --no-init-file -l qa/07-cursor/test.el
  : EMACS_GPU_DISABLE=1 emacs --no-init-file -l qa/07-cursor/test.el

  The test cycles through all cursor types automatically every 2 seconds.
  Press =q= to stop the cycle and leave the cursor in the last mode.

* Checklist

** TODO 7.1 FILLED_BOX — inverted colors
   The cursor cell must have the cursor-color background and the text
   in the cursor background color (colors inverted relative to the text).
   Failure: text is invisible, or cursor has no background fill.

** TODO 7.2 HOLLOW_BOX — four 1px edges, transparent inside
   Four 1px lines forming a rectangle; no fill inside.
   Failure: the interior is filled, or one edge is missing.

** TODO 7.3 BAR — thin vertical line, left edge of cell
   A 1-2px vertical bar on the left side of the current glyph cell.
   For R2L text (test the Arabic line): bar must be on the right edge.
   Failure: bar is missing, too wide (>3px), or on the wrong side.

** TODO 7.4 HBAR — horizontal line, bottom of cell
   A horizontal bar at the bottom of the current glyph cell.
   Failure: bar is at the top, or occupies the full cell height.

** TODO 7.5 Cursor on empty line / fringe fallback
   Move point to the last blank line of the buffer (after all content).
   A cursor must still be visible (rendered in the fringe if no glyph).
   Failure: cursor disappears completely.

** TODO 7.6 Blink off state — cursor disappears completely
   With blink-cursor-mode, when the cursor blinks off, nothing must be
   visible at the cursor position.
   Failure: a ghost outline or partial fill remains during the off phase.

** TODO 7.7 [Metal] BLOCK — no animation on move
   With gpu-cursor-animation set to block, moving point must produce
   no trail, no spring motion, no effects.
   Failure: cursor slides or leaves a trail.

** TODO 7.8 [Metal] SPRING — smooth damped slide
   When the cursor moves a large distance, it must slide smoothly to
   the target with a slight overshoot and settle in ~150ms.
   Failure: cursor teleports instantly, or oscillates without settling.

** TODO 7.9 [Metal] TORPEDO — fading trail on fast movement
   Moving through text quickly must leave a trail of fading cursor images.
   Failure: no trail visible, or trail does not fade.
