Tests assumed renders complete synchronously after requestRender() +
nextTick + flush(), but commit 6f5f37f8 changed requestRender() to
schedule via setTimeout with a 16ms minimum interval. Tests reading
viewport state before doRender() runs saw stale data.
Add VirtualTerminal.waitForRender() helper that waits for the throttled
render to settle (nextTick + 20ms + xterm flush), and replace all
terminal.flush() calls after render-triggering actions with it.
Fixes 8 failing tests across overlay-short-content, tui-render, and
markdown test suites.
Headings applied styling (bold+cyan) as an outer wrapper around the
result of renderInlineTokens. When inline elements like codespan emitted
ANSI resets, the outer heading style was killed and only the default
text style was restored via stylePrefix.
Fix: pass a heading-specific InlineStyleContext into renderInlineTokens
so each text segment gets heading styling directly, and stylePrefix
restores heading style after inline elements.
0x08 (BS) was treated as plain backspace alongside 0x7f (DEL). On
Windows Terminal, Backspace sends 0x7f and Ctrl+Backspace sends 0x08,
making ctrl+backspace bindings unreachable.
Now 0x08 matches ctrl+backspace (and ctrl+h, same byte) but not plain
backspace. 0x7f remains plain backspace.

* feat(tui): treat paste markers as atomic segments in editor
Paste markers like `[paste #1 +123 lines]` are now treated as single
atomic units for cursor movement, word navigation, deletion, and
wrapping. Only markers with valid paste IDs (present in the editor's
pastes Map) are treated atomically.
* fix(tui): word-wrap oversized atomic segments in editor
* feat(tui): extract KillRing and UndoStack, add to Input
Extract kill ring and undo logic from Editor into reusable classes:
- KillRing: ring buffer with accumulation for consecutive kills
- UndoStack<S>: generic stack with clone-on-push semantics
Refactor Editor to use both classes. Add kill ring (kill/yank/
yank-pop), undo with coalescing, and deleteWordForward to Input.
* feat(tui): extract handleBackspace() and handleForwardDelete()
Adds Terminal.prepareForExit() to disable Kitty protocol and wait for
in-flight release events before fully stopping. This prevents escape
sequences from leaking to the parent shell over slow SSH connections.
Fixes#1204
- Remove height change detection (only width changes trigger full redraw)
- Change clearOnShrink default to false (use PI_CLEAR_ON_SHRINK=1 to enable)
- Fix viewport check to use previousLines.length instead of maxLinesRendered
(prevents false positive redraws when appending lines after content shrunk)
- Add clearOnShrink setting to /settings in coding-agent
- Remove line truncation in custom message component (always show full content)
- Add --error-on-warnings to biome check in root and web-ui package.json
- Convert string concatenation to template literals in daxnuts.ts
- Convert string concatenation to template literals in test file
Fixes#1103
When moving up/down through lines of varying lengths, the editor now
remembers the original column position and restores it when reaching a
line long enough to accommodate it.
Example: cursor at column 10, move up to a shorter line (cursor clamps
to end), move up again to a longer line - cursor returns to column 10.
Implementation:
- Add preferredVisualCol instance property (nullable)
- Set it when moving to a shorter line during vertical navigation
- Clear it when arriving at a line that fits the preferred column
- Clear it on any horizontal movement or editing via setCursorCol()
- Detect line rewrap by checking if cursor is in middle of line
- When pressing right at end of prompt, set preferredVisualCol so
subsequent up/down navigation uses that column position
- Add height change detection (analogous to existing width detection)
- Auto-detect when content shrinks below maxLinesRendered and trigger
full re-render to clear leftover empty rows
- Only triggers when no overlays are active (overlays need padding)
Fixes empty rows appearing below footer when:
- Closing /tree or other selectors
- Clearing multi-line editor content
- Any component shrinking
Also adds regression tests for resize handling and content shrinkage.
Added comprehensive bug regression test that demonstrates:
1. The bug scenario (old implementation using startsWith() fails)
2. The fix works (new implementation using includes() passes)
Test covers:
- Terminal without image support scenario (bug trigger)
- Both Kitty and iTerm2 image protocols
- Very long lines (300KB+) matching crash scenario
- Integration with tool execution scenarios
- Negative cases (no false positives)
All 347 tests pass including 12 new bug regression tests.
