File Preview: token colors, line numbers, chrome, and cmux product-blue gutter - #10599
Conversation
File Preview stays on the TextKit 1 NSTextView but no longer paints one flat color. Highlightr token-colors common languages, a gutter draws line numbers, and overlays add current-line highlight plus indent guides. fileEditor.* settings (defaults on) cover highlighting, gutter, guides, current line, and tab width. Files over 256 KiB or 4000 lines skip tokens so large-file selection stays fast. Upstreamed-from: 1d978e6dc2
Replace Highlightr's stock Xcode magenta/coral with light and dark palettes built from the published cmux blues and neutrals. Highlightr still tokenizes; colors are remapped. Chrome (caret line, guides, current gutter numeral) follows the same palette. Upstreamed-from: e82f4a5c4a
NSRulerView’s default fill is a second background. Skip that chrome and fill with the Ghostty panel color so numbers sit in the margin even when the text view itself is transparent. Upstreamed-from: 8d09309151

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to File Preview now parses recognized files for token colors and performs asynchronous editor updates. Size limits and fallback behavior contain exposure, but parser isolation, cancellation/performance behavior, and the tab-width accessibility label still need owner follow-up; the bounded issues are mergeable with explicit awareness.

Greptile SummaryThis PR adds a shared Highlightr-backed syntax-coloring package and upgrades File Preview with token colors, line numbers, current-line highlighting, indent guides, and configurable tab width.
Confidence Score: 4/5The PR appears safe to merge after addressing two non-blocking repository-policy issues around timing-based debounce and incomplete localization. The editor and settings integrations have aligned storage and guarded asynchronous styling, while the remaining accepted concerns are the fixed-delay highlighting debounce and untranslated settings-search content.

In
`@Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Navigation/CuratedSettingEntry`+Default.swift:
- Around line 51-55: Localize the five file-editor entries in
Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Navigation/CuratedSettingEntry+Default.swift
(lines 51-55), including titles and synonyms, using the shared localized
metadata source while keeping setting IDs and configuration paths literal.
Update or remove the duplicated searchText values in
Sources/SettingsNavigation.swift (lines 352-356) so both search surfaces use the
same localized titles, synonyms, and terms, with translated entries for every
supported locale.
In
`@Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/AppSection.swift`:
- Around line 526-591: Update Resources/Localizable.xcstrings with translations
for all ten file-editor localization keys used by AppSection and
CommandPaletteSettingsToggle, covering every supported locale beyond en and ja.
Preserve the existing keys and English/Japanese values while adding localized
values for the remaining 18 locales.
In
`@Packages/Shared/CmuxSyntaxHighlighting/Sources/CmuxSyntaxHighlighting/HighlightColorRemapper.swift`:
- Around line 47-56: The remap(_:) implementation should avoid creating
formatted hex strings for each foreground-color run. Build a private [UInt32:
TokenRole] lookup once from the existing source map, use packed RGB values for
lookups inside enumerateAttribute, and preserve the public String-based API and
existing color-remapping behavior.
In
`@Packages/Shared/CmuxSyntaxHighlighting/Sources/CmuxSyntaxHighlighting/HighlightrSyntaxEngine.swift`:
- Around line 37-42: Update the Highlightr syntax engine’s highlight flow to
retain the last successfully applied theme name in the actor and invoke
setTheme(to:) only when the requested theme differs. Preserve the Bool success
check, update the cached name only after a successful theme application, and
continue highlighting with the optional language and existing remapping flow.
In `@Sources/Panels/FilePreviewEditorChromeOverlay.swift`:
- Around line 124-145: Update leadingIndentColumns to advance each tab to the
next tab stop: after spaces or tabs, add only the remaining columns needed to
reach the next multiple of the normalized tab width. Preserve the existing
handling for spaces, invalid tab widths, and termination at the first
non-whitespace character.
- Line 8: Add an explicit empty deinit to FilePreviewEditorChromeOverlay to
satisfy the active SwiftLint required_deinit rule, matching the existing pattern
used by SavingTextView.
In `@Sources/Panels/FilePreviewEditorSettings.swift`:
- Around line 9-34: Replace the static-only FilePreviewEditorSettings namespace
with a constructable settings reader that stores an immutable UserDefaults
dependency, removing default runtime reads from UserDefaults.standard. Convert
its settings accessors and constants as appropriate for instance use, then
inject this reader into the file preview editor and panel owner so both consume
the injected dependency.
In `@Sources/Panels/FilePreviewLineNumberGutterView.swift`:
- Around line 42-45: Update the gutter-width calculation around lineIndex and
ruleThickness to measure the highest line number using the active
monospaced-digit label font derived from textView.font, rather than reserving a
fixed eight points per digit. Ensure the measurement includes the label’s
required padding and reruns when the active font or its point size changes,
preventing clipping for larger editor fonts.
In `@Sources/Panels/FilePreviewSyntaxStyler.swift`:
- Line 11: Add an explicit deinit to FilePreviewSyntaxStyler to satisfy
SwiftLint's required_deinit rule, without changing the class's existing
behavior.
- Around line 127-149: Update applyHighlightedText and normalized to construct
the regular, bold, and italic monospaced fonts once per applyHighlightedText
call before the attribute-run loop, then pass those cached fonts into normalized
and select among them based on the highlighted font traits instead of rebuilding
fonts per run.
In `@Sources/Panels/FilePreviewTextEditor.swift`:
- Line 227: Add an explicit deinit to the Coordinator class to satisfy
SwiftLint’s required_deinit rule, without changing its existing cleanup or
delegate behavior.
- Around line 499-502: Update applyCurrentPreviewFont to invalidate the
FilePreviewSyntaxStyler memo and force re-highlighting after applying the new
font, rather than only refreshing FilePreviewEditorChromeOverlay. Add and call a
suitable reset method such as invalidateMemo on FilePreviewSyntaxStyler so
scheduleHighlight cannot skip unchanged content after a zoom.
- Around line 137-143: Gate the document scans across all three affected sites:
in Sources/Panels/FilePreviewTextEditor.swift lines 137-143, pass contentChanged
to refreshChrome while keeping overlay frame synchronization unconditional; in
Sources/Panels/FilePreviewSyntaxStyler.swift lines 37-43, replace full-string
comparisons in the styler, including highlighted.value.string == storage.string,
with a cheap content token and avoid retaining a second document copy; in
Packages/Shared/CmuxSyntaxHighlighting/Sources/CmuxSyntaxHighlighting/HighlightPolicy.swift
lines 21-36, validate language and byte limit before lineCount(in:) and count
newline bytes through UTF-8 rather than Characters.
In `@Sources/SettingsSearchAliases.swift`:
- Around line 74-78: Extend the localization entries for the five file-editor
search alias keys in the surrounding settings alias catalog to every supported
locale, adding the missing 18 locale translations while preserving the existing
en and ja entries and key names.

Greptile on manaflow-ai#10599: later edits cancel in-flight highlighting instead of Task.sleep, search titles go through String(localized:), and the new File Editor catalog keys cover all 20 locales already in Localizable.xcstrings.
A font zoom wrote a uniform .font across the storage and then skipped re-highlighting because the text had not changed, so keyword bold/italic stayed flattened. Zoom now forces a restyle. Indent guides treated each tab as +tabWidth columns. A tab now advances to the next tab stop, so mixed space+tab indents line up.

Address the second CodeRabbit review wave (PR manaflow-ai#10599): - FilePreviewLineNumberGutterView now maintains its line index incrementally from NSTextStorage edit notifications, so a keystroke splices a few line-start offsets instead of rescanning up to 16 MB of text on the main actor. Index maintenance is skipped entirely while the ruler is hidden; a wholesale string replace (initial load, legacy no-revision panels) is the only remaining full scan, and the initial build iterates native UTF-16 instead of per-character NSString sends. - FilePreviewSyntaxStyler tracks whether the last pass produced token colors; while a buffer renders the default style, content edits skip the full-range attribute reset (typed text inherits attributes at the insertion point) and the policy is re-checked so a buffer that shrinks back under the ceilings resumes highlighting. - HighlightPolicy line scans iterate UTF-8 bytes instead of Character grapheme clusters. - The curated 'file-editor-word-wrap' settings entry now uses the localized settings.app.fileEditorWordWrap title like its neighbors. cmuxTests still cannot link on this branch: the pre-existing CMUXAuthCore/CmuxAuthRuntime undefined symbols reproduce identically with these changes stashed. Package tests cover the policy change; new styler/index tests are wired into FilePreviewCodeViewTests.

Note GitHub couldn't provide a complete incremental comparison for this pull request, so CodeRabbit is performing a full review instead. This review may take a little longer. |
FilePreviewLineIndex.applyEdit no longer rebuilds lineStartOffsets into a replacement array per edit. Both edit boundaries are binary searches over the strictly-increasing offsets; the surviving suffix shifts in place, the replaced interior is removed with removeSubrange, and only replacement-derived starts allocate. Typing at the end of a document is now O(edit) instead of O(lines). The equivalence test gains two boundary shapes: an edit range starting exactly on a line start and one ending exactly on a line start.

lockfile alongside the XCLocalSwiftPackageReference for CmuxSyntaxHighlighting,
ensuring it reflects the updated package graph.
In
`@Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/AppSection.swift`:
- Line 589: Update the tab-width Stepper associated with accessibilityIdentifier
“SettingsFileEditorTabWidthStepper” to add a localized accessibility label using
“File Editor Tab Width”, ensuring VoiceOver identifies the control by its
setting name rather than its numeric value.
In `@Sources/Panels/FilePreviewSyntaxStyler.swift`:
- Around line 121-125: Update HighlightrSyntaxEngine.highlight to check for task
cancellation immediately on entry, before invoking
Highlightr.highlight/tokenization, and return through its existing cancellation
behavior when canceled.

…ue gutter (manaflow-ai#10599) * feat(file-preview): token colors, line numbers, and editor chrome File Preview stays on the TextKit 1 NSTextView but no longer paints one flat color.

…wser Resolve conflicts with main: - Drop this branch's own syntax highlighter in favour of main's CmuxSyntaxHighlighting / FilePreviewSyntaxStyler (manaflow-ai#10599). Keep FilePreviewSyntaxLanguage for file icons. - Move gitGraph and herd into the relocated RightSidebarMode enum. - Files root: use main's FileExplorerWorkspaceRootResolver for Cloud, keep the pane-local root for local and SSH. - Add newFileBrowser, newGitGraph, newHerd to the exhaustive built-in action switches added on main. - Keep main's search-bar focus fix; keep the workspace-presentation rule that results show only after a query is typed.

Summary
File Preview is no longer a flat monochrome
NSTextView. This PR groups three sequential File Preview changes:fileEditor.syntaxHighlighting,lineNumbers,indentGuides,currentLineHighlight,tabWidth(defaults on / 4). Huge files skip token coloring (256 KiB / 4k-line ceilings) but keep chrome. Markdown TextEdit shares the same editor.#0088FF/#0073D9/#006DC1/#0091FF) plus brand neutrals instead of Highlightr’s stock Xcode magenta/coral. Strings stay muted sand so the page still scans.New shared package:

File Preview replaces its flat monochrome editor with cmux product-blue token colors, line numbers, current-line highlighting, and indent guides while preserving editing, selection, and scrolling. Files over 256 KiB or 4,000 lines keep the editor chrome but skip token coloring; edits and zoom preserve token styling, and line indexing updates incrementally.
