||
* Checklist
|
||
|
||
** TODO 10.1 Scroll down — no artifacts on new content
|
||
Press =C-v= or =C-n= repeatedly. The text that slides up must not leave
|
||
ghost pixels. New content at the bottom must appear cleanly.
|
||
Failure: horizontal bands of garbage at the scroll boundary.
|
||
|
||
** TODO 10.2 Scroll up — same as above but reversed
|
||
Press =M-v= or =C-p=. New content at the top must appear without artifacts.
|
||
Failure: garbage lines appear at the top when new content is drawn.
|
||
|
||
** TODO 10.3 Auto-scroll — smooth and continuous
|
||
Press =s= to start the timer-based auto-scroll (1 line per 60ms).
|
||
The text must slide smoothly without jumps or blank frames.
|
||
Failure: text jumps 2–3 lines at a time, or a blank frame flashes.
|
||
|
||
** TODO 10.4 Horizontal scroll — hscroll, C-e to a long line
|
||
Press =C-e= on the long-line section to hscroll to the end.
|
||
The content must slide horizontally without artifacts.
|
||
Failure: garbled characters or wrong content visible after hscroll.
|
||
|
||
** TODO 10.5 [Metal] Scroll easing — EASE_OUT_QUAD
|
||
Run with: =(setq gpu-scroll-easing 'ease-out-quad)= then scroll.
|
||
The scroll must decelerate smoothly near the target.
|
||
Failure: scroll is instant (easing not applied) or overshoots.
|
||
|
||
** TODO 10.6 [Metal] Scroll easing — SPRING
|
||
Run with: =(setq gpu-scroll-easing 'spring)= then scroll.
|
||
The scroll must overshoot slightly and bounce back.
|
||
Failure: no overshoot visible, or motion never settles.
|
||
|
||
** TODO 10.7 Overlapping copy_region — 1-line scroll
|
||
Scrolling by exactly one line means src and dst regions overlap.
|
||
Content must move correctly (scratch-texture bounce path used internally).
|
||
Failure: the overlapping region shows corrupted or wrong content.
|
||
|
||
** TODO 10.8 Shift on insert — glyph shift correct
|
||
Go to the middle of a content line and insert a character.
|
||
Text to the right must shift exactly one character width.
|
||
Failure: text after the insertion point overlaps, or a gap appears.
