The original code called unix-simple-poll then unconditionally
called unix-read, ignoring the poll result. When poll returned
nil (no data), unix-read would block indefinitely. Fixed by
checking poll result: only read if poll says data is ready.
Same pattern as the draw-text array fix. Application code may call
backend-clear with a framebuffer array instead of a backend instance.
The array method clears all cells to default blank state.
- Replace make-alien unsigned-char buffer with make-array + vector-sap
to avoid SBCL alien type mismatch between signed-char and unsigned-char
- Convert timeout seconds to fixnum milliseconds for unix-simple-poll
(was passing float 0.1, broke on fixnum-typed sb-unix:to-msec)
- Both fixes make read-raw-byte work on SBCL 2.5.2.debian
Application code (passepartout TUI) calls draw-text with a framebuffer
(2D array) as the first argument, but draw-text only had methods for
framebuffer-backend CLOS instances. Added a method on array that sets
cells directly on the framebuffer array, matching make-framebuffer's
return type.
with-terminal macro was only in tangled .lisp (not .org). suspend-backend
and resume-backend generics + simple-backend methods + tests were also
in hand-edited .lisp only. All three added to org/backend-protocol.org
with proper prose, following the literate programming discipline.
Also added suspend/resume assertions to simple-backend-lifecycle test suite.
- Add %read-digits to read multi-digit parameters from raw terminal bytes
- Add %parse-sgr-mouse to decode ESC[<Cb;Cx;CyM/m SGR mouse sequences
into mouse-event structs with :press/:release type and :left/:middle/
:right/:scroll-up/:scroll-down/:drag button classification
- Modified parse-csi-sequence to detect the < marker (0x3C) and
delegate to %parse-sgr-mouse instead of treating it as key input
- Coordinates converted from 1-based (terminal protocol) to 0-based
(framebuffer convention)
- All 12 test suites pass at 100% (461 checks, no regressions)
- Org source (text-input.org) updated as the source of truth
Bug fixes:
- Fix OSC8 format strings (backslash escape layering) in modern-backend.org
- Test format string had single backslash instead of double, causing
unclosed CL string that cascaded through 3 subsequent test forms
- Implementation format string had leading escaped quote (not a string
opener) and triple-backslash ending (also not a string terminator)
- Fix missing closing parens in border-char-rounded and border-char-double tests
- Fix ASDF input-tests pathname (file lives in tests/, not src/components/)
New features:
- Implement suspend-backend / resume-backend protocol methods
- modern-backend: exit/enter alt screen, re-enable mouse/kitty/bracketed-paste
- simple-backend: no-ops (no terminal state to preserve)
Infrastructure:
- Update test suite to cover suspend/resume (backend + modern-backend suites)
- 454 checks, 100% pass across 14 test suites
Add assert to reject invalid mode keywords on first registration
instead of silently storing them and only crashing later in
slot-render's ecase. Valid modes: :stack, :replace, :single-winner.
The osc8-link implementation and its test both had doubled
backslashes (\\ -> \\) in their format strings, producing two
literal backslashes at runtime instead of the single backslash
needed for the OSC 8 string terminator (ST = ESC \).
Fix: change \\ to \\ in both the implementation and test format
strings. The tangled .lisp files now have correct escaped
backslashes (\) producing one backslash in the runtime string.
Additionally clean up a patch artifact that left a stray backslash
before the opening quote.
Add :mode parameter to defslot with three behaviors:
- :stack (default) — accumulate all registrations, render in order
- :replace — each registration replaces previous entries
- :single-winner — first registration wins, rest ignored
Mode is set on first defslot call and frozen for subsequent calls
to prevent conflicting mode specifications from different plugins.
Store slot data as plist (:mode <keyword> :entries <list>) instead
of bare entries list.
Add 5 new tests covering mode-specific behavior. All 9 slot tests
pass. All 13 suites pass at 100%.
- 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.
Distribute the literate prose from the old combined scrollbox-tabbar.org
into three individual module org files:
- scrollbox.org: ScrollBox class, render, scrollbars, bug fixes,
plus the combined test suite (tangles scrollbox-tabbar-tests.lisp)
- tabbar.org: TabBar class, navigation, keyboard handler, render
- container-package.org: Package definition and exports
The old scrollbox-tabbar.org is retained as a documentation archive
with all code blocks set to :tangle no and a redirecting note.
Fixes the draw-scrollbars code block to use the post-bugfix version
(with layout-node origin offset ox/oy), matching the working code.
All 13 test suites pass at 100%.
The tangled handle-text-input used (key-event-text event) for character
insertion, but the test suite creates key events with :code not :text.
Restored the original handle-text-input which uses
(code-char (key-event-code event)) — matching the test expectations.
org/dirty.org is now the source of truth for dirty.lisp and
dirty-tests.lisp. The process:
Overview → Contract → Tests → Implement → Tangle → Test (GREEN)
Hand-written .lisp files were deleted and regenerated from org alone
to prove the pipeline works.
Previous version had 14 failing checks due to wrong function names:
- Theme: load-preset with :keyword mode, not nonexistent load-default-*-preset
- Select: setf select-filter + select-filtered-options with 1 arg
- Dialog: push-dialog/pop-dialog + dialog-title on car of *dialog-stack*
- Mouse: make-box has no :x/:y initargs, use default constructor
- Framebuffer: draw-text on framebuffer-backend, not draw-text-on-fb
- Dirty: dirty-p, not component-dirty-p
- Theme functions in cl-tty.box package, not cl-tty.rendering
Also add ci-watchdog.sh for 15-min polling CI.
All 29 checks now pass.
