# cl-tty v1.0.0 Bug Fix Iteration
> **For Hermes:** Use subagent-driven-development + bug-fix-iteration pattern.
> Each task: inspect → write regression test → fix → verify → commit.
> Do NOT skip tests. Do NOT combine tasks.
**Goal:** Fix all known bugs and blindspots before v1.0.0 release.
**Architecture:** cl-tty is a pure CL terminal UI library. No FFI, no ncurses.
Components: backend (modern/simple escape seq), input (byte reader + event parser),
rendering (framebuffer diff pipeline), layout (flexbox), widgets.
**Verification command after each fix:**
```bash
cd /mnt/hermes/projects/cl-tty && sbcl --script run-all-tests.lisp && python3 scripts/verify-api.py && python3 scripts/verify-demo-pty.py
```

### Task 1: Fix `read-raw-byte` timeout (CRITICAL BUG)
**Objective:** The timeout mechanism uses `get-universal-time` which returns
integer seconds. Adding a float timeout like 0.05 produces a deadline that
equals the current second — the loop terminates immediately. The 50ms escape
ambiguity timeout never actually works.
**Files:**
- Modify: `src/components/input.lisp:84-111`
- Test: `tests/input-tests.lisp` (add regression test)
**Root cause:** Line 99: `(let ((deadline (+ (get-universal-time) timeout)))` —
`get-universal-time` returns integer seconds, so `(+ (integer) 0.05)` = `(+ integer 0)` = integer.
The loop `(while (< (get-universal-time) deadline))` runs zero iterations for any
sub-second timeout.
**Fix:** Use `sb-ext:get-time-of-day` (microsecond precision) or `(/ (get-internal-real-time)
internal-time-units-per-second)` to get fractional seconds. Replace:
```lisp
(let ((deadline (+ (get-universal-time) timeout)))
(loop while (< (get-universal-time) deadline) ...))
```
with:
```lisp
(let* ((start (get-internal-real-time))
(ticks (round (* timeout internal-time-units-per-second)))
(deadline (+ start ticks)))
(loop while (< (get-internal-real-time) deadline) ...))
```
Or simpler: use `(/ (- (get-internal-real-time) start) internal-time-units-per-second)`
to check elapsed time in a loop.
**Verification:**
1. Write a test that calls `read-raw-byte` with :timeout 0.05 and verifies it
returns `(values nil :timeout)` within ~100ms (not instantly).
2. All existing tests still pass.
3. The demo's Escape key works (tested by verify-demo-pty.py).
---
### Task 2: Fix `draw-border` ignoring title in modern backend (BUG)
**Objective:** The `modern-backend`'s `draw-border` method has
`(declare (ignore title title-align))` on line 194. The framebuffer backend
renders titles correctly. The simple backend also ignores titles.
This means titled borders don't show titles in the modern backend.
**Files:**
- Modify: `backend/modern.lisp:192-219`
- Add test: `backend/modern-tests.lisp`
**Fix:** In `draw-border` for `modern-backend`, insert the title text into the
top border line after the first character. The title should be centered or
left-aligned based on `title-align`.
The title rendering logic should extract from the framebuffer backend's
draw-border (framebuffer.lisp lines 114-117) and adapt for escape sequences:
- The top border line is constructed as: `tl + h*N + tr`
- Before writing top: if title is non-nil, insert it: `tl + " " + title + " " + h*fill + tr`
- Truncate title if it exceeds width-4
---
### Task 3: Fix `backend-size` to query real terminal size (MISSING FEATURE)
**Objective:** `backend-size` for `modern-backend` returns hardcoded (80 24).
Should query the terminal via TIOCGWINSZ ioctl or `ESC[18t` query.
**Files:**
- Modify: `backend/modern.lisp:163-165`
- Add test: `backend/modern-tests.lisp` (test that values are positive integers)
**Fix:** Use SBCL's `sb-alien` to call `ioctl` with `TIOCGWINSZ` on the
stdout fd (or /dev/tty):
```lisp
(defmethod backend-size ((b modern-backend))
(sb-unix:unix-ioctl (sb-sys:fd-stream-fd
(or (ignore-errors
(open "/dev/tty" :direction :input
:if-does-not-exist nil))
*standard-output*))
sb-unix:TIOCGWINSZ ...)
;; Or fallback to query-terminal with ESC[18t
;; Fallback: (values 80 24))
```
Simpler approach: Use `sb-unix:unix-ioctl` with the `TIOCGWINSZ` request.
The winsize struct is: (rows columns) as two 16-bit values. In SBCL,
`sb-unix:unix-ioctl` can be used with `sb-unix:TIOCGWINSZ`.
If ioctl is complex, implement via OSC Terminal query: `query-terminal` with
`ESC[18t` returns `ESC[8;rows;colst`. Parse the response.
---
### Task 4: Enable kitty keyboard protocol in `initialize-backend` (MISSING FEATURE)
**Objective:** `modern-backend` declares `:kitty-keyboard` in `capable-p`
but never sends the escape sequence to enable it (`ESC[?u`).
**Files:**
- Modify: `backend/modern.lisp:142-151`
**Fix:** Add to `initialize-backend`:
```lisp
(backend-write b (format nil "~C[?u" #\Esc)) ; kitty keyboard
```
And add to `shutdown-backend`:
```lisp
(backend-write b (format nil "~C[?u" #\Esc)) ; restore default keyboard
```
---
### Task 5: Fix text-input cursor rendering (MISSING VISUAL FEEDBACK)
**Objective:** The `text-input.lisp` render method declares `(declare (ignore cursor))`.
The cursor position is tracked but never drawn, so users can't see where
they're typing.
**Files:**
- Modify: `src/components/text-input.lisp` (render method)
- Add test: `tests/input-tests.lisp` or existing test file
**Fix:** In the text-input render method, after drawing the value/placeholder,
draw a cursor block (█ or reversed ▓) at the cursor position. Use
`draw-rect` or `draw-text` with a visual cursor character at the cursor column.
When the cursor would be beyond the visible area (scrolled past the right edge),
show it at the rightmost position.
---
### Task 6: Fix SS3 branch reading without timeout (POTENTIAL HANG)
**Objective:** In `%read-escape-sequence`, the SS3 branch (when b=#x4f) calls
`(read-raw-byte)` without a timeout parameter. If the terminal sends a partial
ESC O with no follow-up byte, the read blocks forever.
**Files:**
- Modify: `src/components/input.lisp:210`
**Fix:** Change line 210 from:
```lisp
(let ((b2 (read-raw-byte)))
```
to:
```lisp
(let ((b2 (read-raw-byte :timeout 0.1)))
```
And handle the nil case: if b2 is nil, return a key-event for the lone Escape.
---
### Task 7: Add Wayland support to `copy-to-clipboard` (PLATFORM GAP)
**Objective:** `copy-to-clipboard` in `mouse.lisp` only supports X11 (xclip)
and macOS (pbcopy). Wayland users (wl-copy) get no clipboard.
**Files:**
- Modify: `src/components/mouse.lisp:51-54`
**Fix:** Add `#+wayland` or detect Wayland via `$WAYLAND_DISPLAY` env var:
```lisp
(defun copy-to-clipboard (text)
#+linux
(cond
((sb-ext:posix-getenv "WAYLAND_DISPLAY")
(sb-ext:run-program "wl-copy" nil :input text :wait nil))
(t
(sb-ext:run-program "xclip" (list "-selection" "clipboard")
:input text :wait nil)))
#+darwin
(sb-ext:run-program "pbcopy" nil :input text :wait nil))
```
---
### Task 8: Add SIGWINCH handler for terminal resize (MISSING FEATURE)
**Objective:** When the terminal is resized, the demo and any cl-tty app
will render with stale dimensions. The `backend-size` (Task 3) helps but
apps need to be notified of resizes.
**Files:**
- Create: `src/components/notification.lisp` OR modify existing components
**Approach:**
This is a design decision. Options:
a) Install a SIGWINCH handler that sets a flag checked each frame
b) Provide a `register-resize-callback` API
c) Only fix in the demo layer (demo.lisp)
Keep it minimal: install a simple signal handler that sets
`*terminal-resized-p*` to T. The app checks this flag each frame.
Add to `input.lisp` or a new file:
```lisp
(defvar *terminal-resized-p* nil
"Set to T by SIGWINCH handler when terminal resizes.")
(defun %handle-sigwinch (signal info context)
(declare (ignore signal info context))
(setf *terminal-resized-p* t))
;; Install handler
#+sbcl
(sb-sys:enable-interrupt sb-unix:sigwinch #'%handle-sigwinch)
```
---
### Bug Blindspots Verified as NOT Bugs (justifying "won't fix"):
These were investigated and are fine:
- **Framebuffer diff link-url**: `cells-equal-p` compares `cell-link-url` with `equal` — covered.
- **Select with empty options**: `(if (zerop count) (setf (select-selected-index sel) 0)` — handled.
- **Dialog pop from empty stack**: `(when *dialog-stack*` — guarded.
- **`parse-csi-params`**: reads raw bytes, handles EOF gracefully.
- **Thread safety of globals**: out of scope for v1.0.0 (single-threaded TUI).
- **ScrollBox horizontal scrolling**: actually implemented (uses sx in render).
- **Redundant tests removed**: cleanup already done in uncommitted diff.
---
### BLINDSPOT: The `parse-csi-params` function also uses `(read-raw-byte)` without timeout.
Line 122: `(multiple-value-bind (b reason) (read-raw-byte)` — while parsing
a CSI sequence, if the terminal sends ESC[ but never completes the sequence,
this blocks forever. This should use a timeout similar to the escape sequence
reader. Same fix pattern as Task 6.
Adding as Task 9.
---
### Task 9: Fix `parse-csi-params` to use timeout (POTENTIAL HANG)
**Objective:** `parse-csi-params` (input.lisp line 122) reads bytes without
timeout. A partial CSI sequence (ESC[ without final byte) blocks forever.
**Files:**
- Modify: `src/components/input.lisp:116-149`
**Fix:** Add a timeout to the read inside `parse-csi-params`. Use a total
timeout of ~500ms for the entire CSI sequence (generous given terminals
respond within a few ms). If the timeout fires, return nil for final-byte.
Similar to `%read-escape-sequence`, pass `:timeout` parameter to `parse-csi-params`
and have `%read-escape-sequence` pass a timeout to it.
---
### Task 10: Fix `draw-border` ignoring title in simple backend (BUG)
**Objective:** Same as Task 2 but for `simple-backend`. The
`%simple-border-char` function just got refactored (uncommitted diff), and
`draw-border` in simple.lisp also ignores title.
**Files:**
- Modify: `backend/simple.lisp` (draw-border method)
- Add test: `backend/tests.lisp`
**Fix:** In `simple-backend`'s `draw-border`, when a title is provided,
insert it into the top border line. Use ASCII chars (the simple backend
doesn't use Unicode).
---
### Task 11: Add `detect-backend` export to backend package (API GAP)
**Objective:** The README shows `(cl-tty.backend:detect-backend)` as the
entry point, but verify this is actually exported from the backend package.
**Files:**
- Check: `backend/package.lisp`
**Fix:** Ensure `#:detect-backend` is in the package's `:export` list.

# cl-tty Code Audit — Bug Report
## Bug 1 [CRITICAL]: dialog rendering undefined functions
**File:** src/components/dialog-package.lisp and src/components/dialog.lisp
**Problem:** `render-dialog` (lines 34, 36, 39) and `render-toast` (lines 114, 115) call `draw-rect`, `draw-border`, `draw-text` without those symbols being available.
**Root cause:** The dialog package definition uses `(:use :cl :cl-tty.input :cl-tty.select)` but `draw-rect`, `draw-border`, and `draw-text` are generic functions exported from `cl-tty.backend`. They need to be imported. The package does NOT use `cl-tty.backend`.
**Tests don't catch this** because dialog-tests.lisp tests push/pop/toast management but never calls `render-dialog` or `render-toast`.
**Fix:** Add `:cl-tty.backend` to the `:use` list in dialog-package.lisp, or add individual `:import-from` entries for the three functions.
---
## Bug 2 [HIGH]: SBCL "function T is undefined" warning in input.lisp
**File:** src/components/input.lisp
**Problem:** When SBCL compiles this file, it issues:
"WARNING: The function T is undefined, and its name is reserved by ANSI CL so that even if it were defined later, the code doing so would not be portable."
The warning fires during the `defmethod read-event` compilation unit but the exact source is not identified by line number. The file uses `(t ...)` in case/cond default clauses extensively and `:ctrl t`, `:alt t` etc. as keyword argument values. The root cause needs investigation — could be the `case` macro expansion or a `return-from` interaction.
**Note:** this warning does NOT fire when `(compile 'read-event)` or `(compile nil '(lambda ...))` is called in isolation on individual functions. It only fires during `compile-file` on the whole file. This suggests it's a cross-form interaction.
**Investigation needed.**
---
## Bug 3 [MEDIUM]: text-input.lisp ignores variable that IS read
**File:** src/components/text-input.lisp, lines 163, 169-170
```lisp
(w (if ln (layout-node-width ln) 80)) ; line 163 — defined
...
(truncated (subseq display 0 (min (length display) w))) ; line 169 — USED
(declare (ignore w cursor)) ; line 170 — declared ignored
```
**Problem:** `w` is declared as `(ignore w)` on line 170 but is actually read on line 169. Declare ignore + read is a compiler-level contradiction. The `cursor` variable is legitimately unused and should remain ignored.
**Fix:** Remove `w` from the ignore declaration. Only `(declare (ignore cursor))`.
---
## Bug 4 [MEDIUM]: markdown.lisp ignores variable that IS read
**File:** src/components/markdown.lisp, lines 142-144
```lisp
(defun parse-list (lines start)
(declare (ignore start)) ; line 143
(let ((items nil) (i start)) ; line 144 — USES start!
```
**Problem:** Same pattern as bug 3. `start` is declared ignored then immediately used. The declaration should be removed.
**Fix:** Remove the `(declare (ignore start))` declaration.
---
## Bug 5 [MEDIUM]: scrollbox.lisp unused vx variable
**File:** src/components/scrollbox.lisp, line 45
```lisp
(vx 0) (vy 0)
```
**Problem:** `vx` is bound but never read — `vy` is used for viewport height calculations but viewport-x/vx is never referenced. This is a style-warning that indicates either dead code or a real issue where viewport-x should be used.
**Fix:** Add `(declare (ignore vx))` or remove the `vx` binding entirely.
---
## Bug 6 [LOW]: %simple-border-char ignores edge-style
**File:** backend/simple.lisp, lines 33-40
```lisp
(defun %simple-border-char (edge-style pos)
"Return ASCII border character for EDGE-STYLE at POS."
(case pos
((:top-left :top-right :bottom-left :bottom-right) #\+)
(:horizontal #\-)
(:vertical #\|)))
```
**Problem:** The `edge-style` parameter is never consulted. Always returns `+ - |` regardless of style. Callers also pass `nil` for it:
```lisp
(%simple-border-char nil :horizontal)
```
**Fix:** Either remove the `edge-style` parameter (dead code) or implement border style selection using `case` on `edge-style`.
---
## Bug 7 [LOW]: framebuffer draw-border ignores title-align
**File:** src/rendering/framebuffer.lisp, lines 94, 114-116
```lisp
(defmethod draw-border ((fb framebuffer-backend) x y w h &key (style :single) title title-align fg bg)
...
(when title
(loop for i from 0 below (length title)
do (%set-cell fb (+ x 2 i) y (char title i) :fg fg :bg bg))))
```
**Problem:** `title-align` is accepted but never used. Title always renders at offset 2 from left edge (hard-coded). The simple backend centers the title, the framebuffer backend left-aligns — inconsistent API behavior.
**Fix:** Implement `title-align` support or add `(declare (ignore title-align))` and document the behavior.
