- Create org/integration-tests.org (15 blocks, per-test prose)
- Add Markdown tests section to org/markdown-renderer.org (11 test blocks)
- Delete deprecated src/components/input-tests.lisp stub
- Update README.org: tree diagram, literate programming section,
development commands, remove stale test counts
All 13 test suites pass at 100%. Zero .lisp files without org origin.
The combined org file had no unique content — all prose and code were
already in scrollbox.org, tabbar.org, and container-package.org. The
old file's code blocks had the pre-bugfix render/draw-scrollbars
versions and all had :tangle no.
Also update README.org and ARCHITECTURE.org references from
scrollbox-tabbar.org to the individual org files.
Bug fixes:
- read-raw-byte now returns (values nil :eof) on stdin EOF
instead of just nil, so callers can distinguish EOF from
timeout. Previously, non-TTY stdin (pipes, /dev/null)
caused a busy-spin: sb-posix:read returned 0 immediately,
read-raw-byte returned nil, the demo loop treated nil as
'no event yet' and spun at 100% CPU producing 86MB of
repeated rendering frames.
- %read-escape-sequence now uses a 50ms timeout on the first
follow-up byte to resolve the classic Escape-key ambiguity:
a lone Escape press returned an :escape key-event instead of
blocking indefinitely on VMIN=1 VTIME=0. All callers
(SS3, CSI, Alt+char) propagate :eof instead of faking
:escape events when EOF occurs mid-sequence.
- parse-csi-params now uses multiple-value-bind on read-raw-byte
to preserve the :eof signal through CSI parsing.
- simple-backend draw-border now renders :title on the top
edge instead of declaring it (ignore). The title was
silently swallowed — the box rendered with the right border
frame but the title text was never written.
- demo.lisp: removed 'q' as quit key (conflicted with text
input). Only Esc and Ctrl+C quit. Widget event forwarding
scoped to tab 1 (Widgets tab). EOF handling in main loop.
- Stale help text (still said 'q/esc: quit') updated.
Verification infrastructure:
- PTY-based demo test (17 checks) spawns the demo in a real
pseudo-terminal, sends actual keystrokes, reads terminal
output back. Verifies: startup rendering, tab switching,
key dispatch, 'q' doesn't quit, Escape quits via timeout,
Ctrl+C quits, EOF clean exit, no busy-spin.
- API feature verification (29 checks) exercises every major
component through the actual exported API: Simple backend,
Box with title, Text attributes, draw-rect, TextInput
(insert/backspace/cursor/Ctrl-A/E), TextArea, key/mouse
events, Layout flex, Markdown, Theme presets (dark/light/
nord), Select filtering, Dialog stack, Mouse hit-test,
Framebuffer, Dirty tracking, Modern backend, draw-ellipsis/
draw-link, Render dispatch, Detection, Capabilities.
- Testing pattern saved as skill (tui-pty-testing) for reuse.
Unit tests: 392/392 passing. All 12 test suites green.
