CRITICAL: case b → cond in %read-event (input.lisp:280)
case with (and ...) predicate clauses treats keys as eql-compared
atoms — all range clauses were dead code. Every Ctrl+letter and
printable ASCII fell through to :unknown. text-input/textarea
widgets were non-functional with real terminal input. No test
coverage of %read-event masked this.
HIGH: Theme resolution wired (backend/modern.lisp, theme.lisp)
sgr-fg/sgr-bg now fall back to *theme-colors* hash for semantic
keywords (:accent, :text-muted, :background-element). *theme-colors*
exported from cl-tty.backend. load-preset populates it from preset
hex values. Previously all themed render output was invisible.
HIGH: SGR mouse parser wired (input.lisp:210-215)
parse-sgr-mouse was defined but never called. Now %read-escape-sequence
detects ESC[< prefix and routes to parse-sgr-mouse. Mouse drags,
releases, and scroll events now parse correctly.
MEDIUM: Rendering stubs replaced
- scrollbox: delegates to (render child backend) with position
offset via unwind-protect (was debug string 'child at ~D')
- text-input: draws value/placeholder at layout position
- textarea: draws visible lines at layout position
MEDIUM: hit-test uses component-layout-node (mouse.lisp:18-31)
Was checking nonexistent x/y/width/height slots. Now reads
layout-node-x/y/w/h via component-layout-node generic.
MEDIUM: test runner exit code (run-all-tests.lisp, cl-tty.asd)
run-all-tests.lisp exits 1 if any suite fails.
asdf:test-system exits 1 on failure.
Renamed :cl-tty-tests to :cl-tty/test (ASDF convention).
MEDIUM: draw-border respects x/y on simple-backend (simple.lisp:42-53)
Was writing to cursor position only. Now uses newlines+spaces
to reach specified coordinates (no escape sequences needed).
LOW: TabBar truncation off-by-one fixed (tabbar.lisp:47)
>= changed to > to avoid cutting tabs 2 chars early.
LOW: Scrollbar coordinates absolute (scrollbox.lisp:61-73)
Scrollbar drawn at viewport-relative (0,0). Now adds layout
node x/y offset for correct terminal positioning.
LOW: backend-write calls finish-output (modern.lisp:169)
LOW: load-preset no longer flips theme-mode (theme.lisp:43-45)
Mode toggle caused load-preset to load wrong variant on
second call.
All backported to org source files (org/text-input.org,
org/scrollbox-tabbar.org) so tangling produces matching .lisp.
392 tests pass, exit code 0.
