Port Ink's ansi-tokenizer.ts (509 lines) as a standalone ANSI escape
sequence parser that produces typed tokens. Exports tokenizeAnsi() and
hasAnsiControlCharacters(). Supports CSI, ESC, OSC, DCS, PM, APC, SOS,
C1 control characters, string terminator, and invalid/malformed tokens.

Transforms were appended (`[...transformers, node.transform]`) causing outer
transforms to execute before inner ones. Ink prepends so inner transforms run
first and outer transforms wrap the result. Adds a nesting-order regression test.

Port Ink's output character model using @alcalzone/ansi-tokenize. Each cell is now a
StyledChar with proper grapheme clustering. Fixes emoji alignment, wide char boundaries,
and changes clipping to top-only (matching Ink). Upgraded ansi-tokenize to ^0.3.0.

Detect invalid <Box> inside <Text> nesting at the DOM insert level and
emit a dev warning instead of crashing the WASM yoga engine. The box
insertion is skipped to prevent layout corruption.

Ink uses Yoga.EDGE_START for marginLeft and Yoga.EDGE_END for
marginRight, which is correct for RTL-aware layout. Changed from
EDGE_LEFT/EDGE_RIGHT to match.

Match Ink's behavior where Newline renders as ink-text (yoga carrier).
When inside a Text parent, Newline still renders as virtual-text for
inline behavior. When standalone, it renders as a text node so it
participates in yoga layout and occupies vertical space.

Vue's errorHandler (installed after mount) already catches render-time
errors from nested components and routes them through exit(err),
providing error boundary behavior matching Ink's design.

Write ESC[?25l to stdout after mount and ESC[?25h during teardown,
matching Ink's cursor management. Only active in production mode

Transform nodes now participate in yoga layout with flexShrink=1,
flexDirection='row', matching Ink's Transform which renders as ink-text.
This fixes multi-line text under Transform not getting proper layout
height. Transform nodes inside Text parents remain inline (excluded
from yoga tree) to preserve renderTextWithInlineStyles behavior.

Add leading+trailing throttle to the commit scheduler in production mode.
In debug/test mode (immediate: true), commits fire without delay to

Yoga's measure function already receives the content-area width (minus
parent border/padding), so text wrapping is correct without additional
adjustment in the paint pass.

Match Ink's Box defaults by setting yoga properties at node creation time.
This ensures proper row-based layout regardless of Vue's prop patching order.
Updated affected test snapshots and added explicit flexDirection="column"
where tests relied on the old column default.

Add parsing for Home (ESC[H, ESC[1~, ESC[7~), End (ESC[F, ESC[4~,
ESC[8~), Ctrl+arrow (CSI 1;5 A/B/C/D), and Meta+arrow (double-ESC
prefix) key sequences. Add home/end fields to the Key interface.
Implement 12 new useInput tests for these key combinations.

Change exit(error?: Error) to exit(errorOrResult?: unknown). When an
Error is passed, waitUntilExit rejects; otherwise it resolves with the
value. This matches Ink's behavior where exit("hello") resolves the
promise with "hello".

Update renderTextWithInlineStyles and flattenLeaves to handle transform
nodes nested inside text elements, matching Ink's squashTextNodes
behavior. Skip transform application on empty text to avoid wrapping
empty strings. Skip writing empty text nodes to avoid applying line
transformers to empty content.

Add independent horizontal/vertical clip support in the paint pass,
matching Ink's per-axis overflow behavior. Add overflowX/overflowY to
STYLE_PROPS so they are stored in el.props for the paint pass.
Implement 26 new overflow tests translated from Ink.

Guard flattenLeaves and renderTextWithInlineStyles to skip comment
nodes (produced by Vue for null/undefined children) and return empty

zero dimensions for empty text. Expand TuiInlineNode to include
TuiComment since Vue inserts comments into text containers.

Ink's wrap mode uses { trim: false } to preserve leading/trailing
whitespace on wrapped lines. We incorrectly used trim: true which
stripped whitespace. Updates unit test and inline snapshots.

- Remove yoga setOverflow call — Ink only clips visually in paint,
not at the yoga layout level. Calling setOverflow(HIDDEN) prevented
nodes from expanding, diverging from Ink's behavior.
- Fix AlignContent type to exclude baseline (not valid for align-content
in CSS/Yoga, and Ink doesn't allow it).
- Keep border background fallback to backgroundColor — Ink achieves
the same visual result via background fill underneath borders.

The frame writer initialized lastFrame to "" and also reset it to ""
on clear(). Since commit() calls clear() then write(), any component
that painted to an empty string (e.g. Transform with no children, or
a component returning null after unmounting children) would be
deduplicated against the cleared state and never emitted.
Use null as the sentinel for "no previous frame" so the first write
after a clear always goes through, even when the frame is empty.
Fixes: Transform with null/undefined children tests
Fixes: Focus unmount crash tests (stale frame persisted)

Previously Output.get() only used the last clip rect (clips.at(-1)),
which meant an inner overflow:hidden box wider than its outer ancestor
could effectively loosen the outer clip. Now all active clips are
intersected via reduce, and writes are skipped entirely when the
intersection is empty.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Port Ink's clip/unclip approach to vue-tui's paint output. When a box
has overflow="hidden", content painted by its children that falls
outside the box's content area (inside borders) is clipped.
Implementation:
- Add ClipRect, clip(), and unclip() to the Output class
- Maintain a clip stack; active clip is applied to each write op
- Horizontal clipping uses slice-ansi for correct ANSI handling
- Vertical clipping slices the lines array
- Store "overflow" in STYLE_PROPS so it's available in node.props for
the paint pass
Also adds explicit flexDirection="row" to two overflow tests where
multiple child boxes should lay out side-by-side (Ink defaults to row,
vue-tui defaults to yoga's column).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Ink's <Text> sets flexShrink: 1 by default so text nodes shrink when
they overflow their container in no-wrap flex rows. Without this,
vue-tui's text nodes had flexShrink=0 (yoga default) and would never
shrink, causing overflow tests to fail.
Also ports Ink's measureTextNode guard: when yoga asks if text can fit
in a sub-1px space during shrink calculations, return the natural
dimensions to prevent text from wrapping to infinite height.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Ink's Box defaults to flexDirection="row", so multiple <Text> children
lay out side-by-side. Vue-tui uses yoga's default (column). Rather than
changing the global default and breaking 20+ existing tests, add
explicit flexDirection="row" to the inner boxes in these two tests so
they match the intended layout behavior being verified.

The space-around alignment distributes space as 1-row gap / AB / 2-row
gap / CD / 1-row gap for a 6-row container with 2 content rows.
Expected value was "\nAB\n\nCD\n\n" but Ink produces "\nAB\n\n\nCD\n".

height=6 containers produce 6 lines. Ink's renderToString returns
"A\n\n\nB\n\n" (preserving trailing blank lines). The tests incorrectly
expected "A\n\n\nB" with a comment claiming lastFrame({ trimLines: true })
trims trailing newlines — it does not; it only trims trailing spaces per
line.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Ink's Output.get() calls .trimEnd() on each line of the rendered grid.
Without this, vue-tui's paint grid always fills the full root width with
spaces, causing raw frame output to contain 100-char-wide padding. This
broke tests using { raw: true } and made meaningful trailing-space
assertions impossible with { trimLines: true }.
Also corrects test assertions for 'set width in percent' and 'relative
position' that expected trailing spaces which Ink never produces.

Distributes across text, static, transform, newline-spacer,
error-handling, and prop-reset test files.
Tests requiring features not yet in vue-tui are marked test.todo:
- <Transform> inside <Text> (paint pass limitation)
- multi-line transform (transform nodes not yoga carriers)
- text/box nesting validation (no runtime validation yet)
- complex Static rerender patterns (Ink-specific API)
Also fixes wrap="hard" to use wordWrap:false so text breaks at exact
character boundaries rather than word boundaries, matching Ink behavior.

Adds 17 text tests from Ink: color (standard/hex/rgb/ansi256),
background color, dim, bold, inversion, reactive remeasure, and
edge cases. 4 tests skipped due to null-children yoga crash and
constructor text lookup bug.
Also fixes lastFrame() treating empty-string frames as undefined

Translates flex, direction, wrap, align, justify, gap, padding,
margin, width-height, position, display, and overflow tests from
Ink. Adds trimLines mode and trailing-newline strip to test helper.
Fixes Box type for alignContent (space-between/around/evenly) and
alignSelf (stretch/baseline).
21 tests fail due to behavioral differences (overflow clipping,
percentage dimensions, relative position offsets, align-content
space-* variants). These represent real gaps to investigate.
