fix(mobile): respect word wrap in diffs - #12590
Conversation
The Code & Diffs "Word break" setting only reached the file viewers. The native review diff view never received it, so long diff lines always ran off-screen behind a horizontal pan. Pass wordWrap through the native diff style. When it is on, iOS and Android split each code line into fixed-width column segments, grow the row by one line height per extra segment, split word diff highlights at the same boundaries, and disable horizontal code panning. Layout rebuilds when the view width changes. Comment card snippets stay unwrapped because their height is sized from the row count. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Wrap breaks now move back to a composed character boundary so emoji and combining marks never split across visual lines. Each wrapped row's line starts are computed once during layout and shared by the row height, the drawn segments, and the word diff highlights. On Android, code text drawing moves into ReviewDiffCanvasDrawing, which keeps drawLineRow and DiffCanvasView within detekt's size limits. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
CodeWrapLayout owns the wrap columns, line height, and per-row line starts, built by ReviewDiffCanvasDrawing. DiffCanvasView keeps a single field, which brings it back under detekt's LargeClass threshold. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Use four-character tab stops for wrapped Android code.
Tabbed text reaches StaticLayout, which has no TabStopSpan. Android therefore advances a leading tab from 0 to 20 px and later tabs to the next 20-pixel boundary. This is narrower than the configured four-character monospace interval and can visibly reduce indentation and change wrapping. The layout is rendered directly with nativeLayout.draw(canvas). iOS uses characterWidth * 4, so Android should use the same interval.
🐛 Proposed fix: attach 4-character tab stops before building the layout
- val layout = StaticLayout.Builder.obtain(text, 0, text.length, paint, max(1, width))
+ val tabWidth = (characterWidth * 4f).toInt().coerceAtLeast(1)
+ val laidOut = if (text.contains('\t')) {
+ val spannable = if (text is Spannable) text else SpannableString(text)
+ val stops = max(1, max(1, width) / tabWidth) + 1
+ for (stop in 1..stops) {
+ spannable.setSpan(
+ TabStopSpan.Standard(stop * tabWidth),
+ 0,
+ spannable.length,
+ Spanned.SPAN_EXCLUSIVE_EXCLUSIVE,
+ )
+ }
+ spannable
+ } else {
+ text
+ }
+ val layout = StaticLayout.Builder.obtain(laidOut, 0, laidOut.length, paint, max(1, width))
.setAlignment(Layout.Alignment.ALIGN_NORMAL)Add the imports android.text.Spannable and android.text.style.TabStopSpan.

Coalesce wrapped relayouts for token patches.
When wordWrap is enabled, each non-empty patch posted by setTokensPatchJson assigns tokensByRowId on the UI thread. The setter then traverses all rows, rebuilds the row-offset array, and calls requestLayout(). CodeLayoutCache reuses unchanged CodeLines, but it does not avoid the full row traversal, map creation, or offset-array allocation. Large diffs can produce multiple patches as the visible range moves, so this work can repeat and cause frame loss.
The theme setter also relayouts when it receives an equal DiffTheme. Add equality checks and coalesce the wrapped relayout into one posted pass.

Assert that raster rendering produces visible text before checking overflow. Neither raster test asserts non-zero alpha inside the viewport. The Android geometry checks and the iOS height, geometry, and reconstruction checks do not inspect rendered pixels. If the drawing path returns without drawing glyphs, the outside-viewport checks still pass. Add an assertion that at least one pixel in the code viewport has non-zero alpha in each raster case.

Performance measurements for UIKit native renderer — repeated before/after benchmark Apple M4 Max, macOS 27.0, Mac Catalyst UIKit, optimized Swift. Seven measured fresh-view trials after one warm-up per revision/size. 80% ASCII / 10% CJK / 10% emoji + combining marks; viewport 390×844 points at 2×. Paint measurements invoke the production drawing method into a fresh bitmap, including text and word backgrounds; not a cached layer snapshot.
¹ Median of seven trial-level p95s, each from 31 paints. Other repeated operations use trial medians. The tradeoff is real: correct Unicode measurement increases cold wall time to about 712 ms for 10k rows. Initial preparation runs on the decode worker; the median longest observed main-run-loop iteration falls from 13.46 to 2.31 ms. Cached comment toggles improve about 6×. Warm highlighted viewport paint is about 25% lower in this fixture; first paint is slower. Corrected wrapping changes visible geometry, so these are viewport costs, not equal-glyph throughput comparisons. Width/font invalidation was not benchmarked. Run-loop observations are not phone frame times, and bitmap paints are not GPU/presentation timings. Android app scrolling — current revision only Full debug app, Pixel 9 / Android 16 x86_64 emulator on Ryzen 7 8845HS, 60 Hz. T3 Device stream active, no screen recording. Used the real highlighted diff fixture (ASCII, CJK, emoji, accents, Arabic, tabs) over the isolated remote backend. Reset Android gfxinfo counters before each sample, then performed ten alternating 1300 px swipes with 700 ms pauses. Startup/navigation excluded.
Combined: 98/1468 frames (6.68%) missed the 16.7 ms deadline. This is not jank-free. These are whole-app Android gfxinfo measurements on a streamed debug emulator; they do not isolate the renderer or prove a regression/improvement. No original-PR Android frame baseline or physical-device/release measurement was taken. Sample windows include idle time, so dividing frame counts by wall time would not produce meaningful FPS. Download raw samples, benchmark source, reproduction script, and methodology. No app-code changes for this measurement. |

Profiled scrolling a complete 10,000-changed-row diff on Android at Pixel 9 / Android 16 x86_64 debug emulator, 60 Hz, Ryzen 7 8845HS, Device stream active. One TypeScript file with 5,000 deleted + 5,000 added lines, 80% ASCII / 10% CJK / 10% emoji + combining accents, wrapping and word-change backgrounds enabled. Native logs confirm 10,044 entries including surrounding headers/other fixture entries. The 937 KB patch fits under the server's 1 MiB per-file preview limit. Frame health, original source restored, no instrumentation or system trace running Each pass: 20 one-way swipes, 1300 px, 700 ms pauses. Counters reset before the outbound pass; each frame read resets the next window. Loading and build activity excluded.
Combined 220/1,842 = 11.9%. Large-diff scrolling is not consistently smooth on this setup. This is a streamed debug emulator, not a physical-device release measurement. Where the time goes
Trace slices overlap; do not add those elapsed times together. JavaScript consumed only 235 ms on CPU in the retained trace, versus 4,030 ms on the UI thread and 12,853 ms on RenderThread. It was not the dominant CPU consumer in this run. Controlled code experiment A temporary Android-only prototype replaced the linear header scans with an index. Native timers, first 120 draws discarded:
That removes about 36% of native draw time in this fixture. One run each, 720 vs 840 warm draws. Both use the same timers; only the baseline also had Perfetto active. Treat this as evidence for removing the header scan, not a controlled claim about end-to-end frame-rate improvement. The prototype was restored, and the original app rebuilt/reinstalled. No production changes committed for this profile. Syntax highlighting stops following the viewport Only the initial 239 rows received syntax tokens; at line ~1,674, syntax colors are absent while word-change backgrounds still work. The shared hook compares each event with the immediately previous event and then overwrites that reference. Movement of 1–2 rows per frame never accumulates to its 20-row threshold. Compare against the last requested/highlighted range instead, and guarantee settled-viewport coverage. This needs fixing before using these numbers to represent fully syntax-highlighted scrolling. Once token delivery is corrected, also remeasure token-triggered full-row layout passes. They were not recurring during this scroll because highlighting had stopped; initial layout calls reached 26.8 ms in the instrumented run.

Note: GPT-6 on behalf of shivam (@shivamhwp). At The Android comparison shows why startup performance also matters: the measured prototype fixed the clipping cases but increased layout time from about 13 to 39 ms for 1,000 mixed rows. Similar cached drawing times do not remove the initial layout cost. I see |

Fixed the syntax-highlighting starvation found in the large-diff profile in c3a864a. The shared mobile hook now compares viewport movement against the last requested range. Small scroll events accumulate instead of resetting the threshold on every event. A 150 ms trailing refresh covers the final viewport when movement stops below the threshold; duplicate draw events do not postpone it. Pending refreshes are canceled when the diff changes or unmounts. Validation:
The physical-phone previews previously installed at ab3d9b3 have not been redeployed with this follow-up yet. Implemented and verified by GPT-6 via Codex. |

The mobile review diff now follows Settings → Appearance → Code & Diffs → Word break. Long lines wrap to the viewport, with line numbers, selection, and word highlights using the same row geometry.
Printable ASCII keeps the fixed-column shortcut. Unicode and tabs use native text layout (TextKit on iOS, StaticLayout on Android), fixing clipping caused by counting UTF-16 units as equal-width glyphs. Initial row preparation uses the existing decode worker; cached geometry is reused when comment heights change. Drawing skips offscreen text, and iOS retains full TextKit drawing layouts only for recently drawn rows.
Width/font changes invalidate geometry. Wrapping disables horizontal code panning; hunk headers and comment-card snippets remain single-line/unwrapped. This changes mobile presentation only, with no wire, provider, web, or desktop changes.
Before / after
Same synthetic Unicode rows and style, rendered by the real iOS view using Mac Catalyst UIKit. Before is the original PR head
f95e22ae670; after includesab3d9b3fbf9. CJK, emoji, combining marks, Arabic, tabs, and word highlights are covered. With wrapping disabled, the before/after renders are byte-identical.Simulator verification
Built and installed the final native client on iPhone 17 Pro / iOS 26.5 against an isolated backend. Verified wrapping off/on, complete Unicode end markers, scrolling through a longer diff, and tapping a wrapped continuation: the comment editor selected original line 1 and retained the full source. Saving the comment created an unsent draft attachment.

Build setup: the temporary checkout needed the native-client helper's Expo
--deviceargument changed from the emulator serial to its AVD name. App sources remained at the pushed commit. This is emulator functional verification, not a physical-device frame-time benchmark.Validation and performance
Synthetic Mac Catalyst benchmark: 10,000 rows, 80% ASCII / 10% CJK / 10% emoji. These are desktop UIKit timings, not phone frame/GPU measurements.
Correct Unicode measurement costs more cold preparation time, now prepared on the decode worker. Width/font changes still require fresh layout; this does not claim every layout operation is asynchronous. Before measurements · After measurements.
Original implementation: Claude Opus 5 / Claude Code. Follow-up fixes and verification: GPT-6 / Codex.
