Closes #10319

Summary

The built-in text editor always rebuilt its font from a hard-coded 13-point monospaced system font, and it never supplied paragraph styling. That made Markdown preview typography disappear whenever a panel switched into edit mode.

This change adds the fileEditor.fontFamily, fileEditor.fontSize, and fileEditor.lineHeight settings alongside the existing fileEditor.wordWrap setting. Config parsing, the typed settings catalog, Settings UI, schema/docs, and all web locale catalogs now expose the keys. The TextKit 1 editor resolves installed AppKit families with a monospaced fallback, uses the configured size as the per-editor zoom reset baseline, reapplies global magnification, and applies NSParagraphStyle.lineHeightMultiple to existing and newly typed text. Markdown edit mode and ordinary file previews share the same path.

Verification

  • swiftc -parse on all changed Swift sources and tests
  • JSON parsing for web/data/cmux.schema.json, Resources/Localizable.xcstrings, and all 20 web/messages/*.json catalogs
  • ./scripts/check-pbxproj.sh
  • ./scripts/lint-pbxproj-test-wiring.sh
  • python3 scripts/check-package-resolved-policy.py
  • Added runtime behavior coverage for typography resolution, TextKit paragraph styling, zoom reset behavior, and settings-file parsing

Per repository policy, no local Xcode build/test or app launch was performed; hosted CI is the build/test gate.

Summary by cubic

Closes #10319. Makes the built-in plain-text editor's font family, size, and line height configurable, replacing the fixed 13-point monospaced system font and restoring Markdown preview typography in edit mode. Cmd-0 now returns each editor to the configured baseline without clearing explicit zoom overrides.

  • Adds fileEditor.fontFamily, fileEditor.fontSize, and fileEditor.lineHeight to Settings UI/search, config parsing, schema/docs, and localized strings; no migration required.
  • Applies typography live to existing and typed text while preserving paragraph styling on reset; clamps size to 8–36pt, line height to 0.5–3, and resolves families with a monospaced fallback.
  • Scopes settings observation to mounted editors, skips redundant normalization, and guards content/typography sync so reloading panel text during a typography update doesn't publish stale editor content back.

Written for commit 86f9484. Summary will update on new commits.

Note

Low Risk
User-facing editor typography and settings plumbing with validation and regression tests; no auth, security, or data-handling changes.

Overview
Adds fileEditor.fontSize, fileEditor.fontFamily, and fileEditor.lineHeight as first-class settings (catalog, App settings UI, search/deep links, cmux.json import/template, JSON schema, and docs/locales), alongside existing file-editor options.

The plain-text FilePreviewTextEditor now reads those values via @AppStorage on the text view (word wrap moved here too) so Settings edits do not invalidate unrelated surfaces like the Markdown WebView. SavingTextView applies family/size/line-height live, treats the configured size as the Cmd-0 zoom baseline while keeping per-editor zoom overrides, and syncs content reloads under a delegate guard so typography updates do not publish stale text.

New persistence helpers clamp/quantize values; tests cover resolution, config import, paragraph-style preservation, and zoom behavior.

Merge Risk: 🔵 Low · up to 31d96

The PR is mergeable with explicit owner follow-up: resetting line-height settings may replace unrelated paragraph styling, several localized descriptions need wording corrections, and a test helper may still violate a lint rule. These are bounded correctness, documentation, and readiness issues rather than release-blocking impact.

Full details: Description check

Explanation

The description explains what changed, why it changed, and how it was verified. It does not include the template checklist or demo video section, but the required change and testing details are substantially complete.

Full details: Linked Issues check

Explanation

The changes satisfy issue #10319 by adding fileEditor.fontFamily, fileEditor.fontSize, and fileEditor.lineHeight, preserving monospaced defaults, supporting zoom reset behavior, applying paragraph line height, and retaining coexistence with wordWrap.

Full details: Out of Scope Changes check

Explanation

The configuration, editor behavior, Settings UI, schema, documentation, localization, project registration, and regression tests directly support the typography feature. No unrelated code changes are evident.

Full details: Cmux Swift Actor Isolation

Explanation

No changed production declaration matches the failure conditions. AppSection is explicitly @MainActor, and FilePreviewTextEditingPanel plus the NSViewRepresentable/NSTextView path are UI-bound. The new typography helpers are synchronous settings and normalization helpers; their parser use reads static constants and performs pure normalization, with no new background task or actor crossing. FileEditorCatalogSection only extends an existing SettingCatalogSection with DefaultsKey values, matching the existing catalog-section pattern. The PR adds no Sendable mutable reference type or async service protocol. The added actor annotation is on a test spy, which the check allows. The magnification observer also delivers its callback on the main actor.

Full details: Cmux Swift Blocking Runtime

Explanation

PASS: The PR adds typography settings and synchronous TextKit attribute updates, but it does not add blocking or timing-based runtime synchronization. An exact added-line scan across the PR Swift diff found no DispatchSemaphore, blocking .wait, sleep, asyncAfter, polling, main.sync, or manual-lock APIs. The existing NSLock and DispatchQueue.main.asyncAfter in FilePreviewPanel.swift, and existing sleeps/delays in MarkdownPanelView.swift, are unchanged from the PR base.

Full details: Cmux Browser Automation Off-Main

Explanation

PASS: The pull request does not change browser socket automation. The merge-base diff changes file-editor settings, typography, documentation, localization, and related tests only. Sources/TerminalController.swift, ControlCommandExecutionPolicy.swift, and the control-socket policy tests are unchanged. No added lines introduce browser.* commands, WebKit waits, worker routing, or browser state access. Therefore the browser-automation off-main failure conditions do not apply.

Full details: Cmux Expensive Synchronous Load

Explanation

PASS. The pull-request diff adds no RestorableAgentSessionIndex.load(), SharedLiveAgentIndex access, agent hook/session-store reads, transcript or trajectory loads, JSONL parsing, directory scans, per-record syscalls, or socket/close-path loads. The changed production paths only read UserDefaults, resolve NSFont, and apply typography to the editor text storage. The only added FileManager operation is test cleanup. Existing synchronous fallback call sites remain unchanged, so this check finds no introduced expensive synchronous agent-history load.

Full details: Cmux Cache Substitution Correctness

Explanation

PASS: The feature adds direct UserDefaults setting reads and event-driven @AppStorage/DefaultsValueModel observation. It does not replace a fresh read with a cache in a persistence, history, undo, or snapshot path. Editor content synchronization still compares and loads panel.textContent; the new typography code only updates text-view attributes. The feature commit diff contains no new cache or snapshot consumer.

Full details: Cmux No Hacky Sleeps

Explanation

PASS. The full PR diff contains only one covered non-Swift source file, a documentation example in web/app/[locale]/(landing)/docs/configuration/page.tsx. Its changes add commented configuration entries only. The diff introduces no sleeps, timers, polling, delayed dispatch, or wall-clock synchronization. The remaining runtime changes are Swift, which this rule explicitly excludes.

Full details: Cmux Algorithmic Complexity

Explanation

PASS — The production changes do not introduce a stated complexity violation. SavingTextView+Typography.swift performs a linear traversal of disjoint attributed-text runs and one linear update pass. It has no nested full-collection scan or per-target rescan. The pass runs on typography changes or content reloads, not on every typing event. The other changed operations use fixed-size settings keys, shortcut candidates, or static search entries. No new sorting, filtering, in-memory join, or batch action over scalable records was introduced.

Full details: Cmux Swift Concurrency

Explanation

PASS. The PR diff from merge base cef69a7052c5 to 31d96db57 adds no background Dispatch queues, DispatchGroup, completion-handler API, or fire-and-forget Task in cmux runtime code. The only new concurrency-related lines are in cmuxTests/FilePreviewTextEditorTextKitTests.swift: a Combine import, an @MainActor test spy conforming to the existing ObservableObject constraint, and its required Task-returning stub. This is test-only usage and does not add app state or async flow. Existing runtime async and Combine patterns were not materially expanded by the diff.

Full details: Cmux Swift `@Concurrent`

Explanation

PASS — The PR does not introduce a Swift concurrency annotation violation. The diff adds no nonisolated async declaration and no @concurrent declaration. The new typography and settings code is synchronous. Existing async helpers in FilePreviewPanel, including the @concurrent file load/save/mode helpers and the detached application refresh, are unchanged. The only added concurrency-related declaration is a @MainActor test spy, with no @concurrent misuse or heavy async work introduced.

Full details: Cmux Swift Package Boundaries

Explanation

The diff adds independently testable settings policies to the app target. Sources/Panels/FilePreviewFontSizeSettings.swift and Sources/Panels/FilePreviewLineHeightSettings.swift import only Foundation/CoreFoundation and implement defaults access, bounds, clamping, rounding, and persistence. They do not depend on AppKit, SwiftUI state, Ghostty, or app lifecycle. The app target registers them in cmux.xcodeproj, while the new tests directly exercise their policy behavior. This matches the policy's app-root domain-logic failure condition. The AppKit SavingTextView code is UI glue and is not the failure basis. CmuxSettings already provides an appropriate SwiftPM boundary with analogous BrowserZoomSettings and package-level tests.

Resolution

Move the pure file-editor settings policy out of Sources/Panels and into the existing CmuxSettings package, for example under Packages/macOS/CmuxSettings/Sources/CmuxSettings/Policies. Expose FileEditorFontSizeSettings first, followed by FileEditorLineHeightSettings, with their defaults keys, bounds, normalization, rounding, and UserDefaults access. Update the app parser, template, editor, and tests to use the package API. Move the corresponding policy tests into CmuxSettingsTests. Keep FilePreviewFontFamilySettings.font(...), SavingTextView+Typography.swift, and other AppKit/editor composition in the app target.

Full details: Cmux Swiftpm Lockfiles

Explanation

PASS. The PR range changes no Package.swift, Package.resolved, .gitignore, or workflow file. The only Xcode project change is cmux.xcodeproj/project.pbxproj, and its diff adds Swift source file references/build-phase entries and fixes indentation. It does not change packageReferences, XCRemoteSwiftPackageReference, or package products. Therefore no SwiftPM dependency resolution or Xcode package-reference change requires a lockfile diff.

Full details: Cmux Swift Logging

Explanation

PASS. The feature diff adds no print, debugPrint, dump, NSLog, ad hoc stdout/stderr logging, or new Logger declarations. The new invalid-setting diagnostics call the existing logInvalid helper, which uses the existing nonisolated private unified logger and hashes both the setting path and source path with .private(mask: .hash). No logging-policy failure was introduced.

Full details: Cmux User-Facing Error Privacy

Explanation

PASS — The typography diff adds settings labels, help text, aliases, schema/docs, and internal validation diagnostics. The user-facing text contains only file-editor typography terms and configuration keys. Invalid settings call cmuxSettingsFileStoreLogger.warning with .private(mask: .hash) values; they do not create alerts, command output, API error bodies, or recovery copy. Tests and comments are also allowed by the rule. No vendor, provider, credential, token, header, raw upstream message, or payload exposure was introduced.

Full details: Cmux Full Internationalization

Explanation

The PR adds ten new app string-catalog keys, but each has translations only for en and ja. Resources/Localizable.xcstrings already supports 20 locales, so the new File Editor labels, subtitles, placeholder, and search aliases are missing translations for ar, bs, da, de, es, fr, it, km, ko, nb, pl, pt-BR, ru, th, tr, uk, zh-Hans, and zh-Hant. The Swift call sites do use String(localized:defaultValue:), and the web changes cover all 20 locales in web/i18n/routing.ts, but the app catalog additions violate the full-internationalization rule.

Resolution

Add genuine translated localizations entries for all 18 missing locales in Resources/Localizable.xcstrings for these keys: settings.app.fileEditorFontFamily, settings.app.fileEditorFontFamily.placeholder, settings.app.fileEditorFontFamily.subtitle, settings.app.fileEditorFontSize, settings.app.fileEditorFontSize.subtitle, settings.app.fileEditorLineHeight, settings.app.fileEditorLineHeight.subtitle, settings.search.alias.setting.app.file-editor-font-size, settings.search.alias.setting.app.file-editor-font-family, and settings.search.alias.setting.app.file-editor-line-height. Do not use English copies, empty values, or machine markers.

Full details: Cmux Swiftui State Layout

Explanation

PASS. The SwiftUI diff adds three @State-held DefaultsValueModel instances in AppSection; DefaultsValueModel is already @Observable, so this uses the required modern shape. The new controls write state only from Binding action closures, and observation starts in .task, not during body rendering. The added settings rows are in an eager SettingsCard VStack, not a lazy/list row subtree. No new GeometryReader or render-time state write appears. The ObservableObject and @ObservedObject usages in the editor remain the existing NSViewRepresentable AppKit bridge, and the new test spy is only a bridge test double.

Full details: Cmux Architecture Rethink

Explanation

No architectural-rethink failure is introduced. The diff adds no timing, blocking, polling, lock, or delayed-dispatch repair path. The isApplyingPanelUpdate flag already existed on the base branch; the new synchronous withPanelUpdate helper gives that existing delegate guard a scoped invariant. The new @AppStorage values are documented SwiftUI-to-AppKit bridge snapshots, and the change moves shared editor observation out of two parent views into the mounted editor rather than adding duplicate surfaces. Editor-local typography and zoom state has a clear owner in SavingTextView. The settings catalog remains the persistence source, and the editor normalizes values before applying them.

Full details: Cmux Swift Auxiliary Window Close Shortcuts

Explanation

PASS. The PR changes file-preview/editor views and typography settings, but adds no production NSWindow, NSPanel, NSWindowController, SwiftUI Window, or WindowGroup code, and adds no window identifier assignment. The new NSWindow usage is a test fixture in cmuxTests/FilePreviewTextEditorTextKitTests.swift, which the rule allows. The existing SavingTextView.performKeyEquivalent method predates the feature and is not changed into Cmd+W or close handling. scripts/lint_auxiliary_window_close_shortcuts.py passes and checks 35 existing cmux window identifiers.

Full details: Cmux Source Artifacts

Explanation

PASS. The diff from merge base cef69a7 contains only Swift source, tests, the Xcode project file, configuration/schema, documentation, and localization catalogs. The four added files are typography implementation sources under Sources/Panels. All changed files remain regular 100644 text files, and the diff has no binary-file markers, scratch/build/cache directories, logs, screenshots, recordings, or copied artifacts. The Packages paths are repository source and test paths, not dependency checkouts.

Full details: Cmux No Test Or Debug Seam In Production Source

Explanation

PASS: The production Swift diff adds no #if DEBUG, #if TESTING, XCTest guard, or test/debug-named member. The widened SavingTextView typography state is consumed directly by production behavior, and withPanelUpdate is called by updateNSView; neither is a test-only accessor. Test scaffolding remains in cmuxTests/FilePreviewTextEditorTextKitTests.swift and uses @testable import.

Full details: Cmux No Ambient Global State

Explanation

The production Swift changes do not introduce a prohibited ambient global. The new FilePreviewFontFamilySettings, FilePreviewFontSizeSettings, and FilePreviewLineHeightSettings are constructable structs with injected UserDefaults and instance resolvedDefault/setDefault behavior. Typography behavior is implemented as SavingTextView instance methods. The added static members are constants or helpers, and no new file-scope mutable variable, free API function, stub namespace type, or shared/standard/default singleton declaration appears in the final PR diff.

83-89: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve unrelated paragraph attributes when resetting line height.

removePreviewLineHeightFromTextStorage() removes the entire .paragraphStyle attribute. This also removes alignment, paragraph spacing, tab stops, and other paragraph attributes. When lineHeight returns to 1.0, reset only the line-height fields while preserving the rest of each NSParagraphStyle. Add a regression test for this behavior.

Greptile Summary

The PR adds configurable font family, font size, and line height throughout the native file-editor settings, configuration parser, editor runtime, schema, documentation, and locale catalogs. The native typography catalog additions still omit locales already supported by the touched catalog.

  • Adds typed settings, Settings UI controls, search entries, JSON parsing, and generated configuration defaults.
  • Applies configured font and paragraph styling to existing and newly typed editor content while preserving per-editor zoom behavior.
  • Updates web documentation, schema data, locale messages, project wiring, and typography tests.

Confidence Score: 4/5

The PR is not ready to merge because the new native typography controls and search aliases remain untranslated in catalog-supported locales beyond English and Japanese.

The current catalog entries still provide only English and Japanese values, so users in other supported native locales receive fallback UI text and cannot search using localized typography terms.

Files Needing Attention: Resources/Localizable.xcstrings

Important Files Changed

Filename Overview
Sources/Panels/FilePreviewTextEditor.swift Observes file-editor typography settings at the mounted editor and coordinates content, typography, wrapping, and zoom updates.
Sources/Panels/SavingTextView+Typography.swift Resolves configured fonts and applies line-height attributes to text storage and typing attributes.
Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/AppSection.swift Adds persisted controls for file-editor font family, size, and line height.
Sources/KeyboardShortcutSettingsFileStore+SectionParsers.swift Parses, validates, rounds, and normalizes the three new file-editor configuration values.
Resources/Localizable.xcstrings Adds native typography and search strings but leaves catalog-supported locales other than English and Japanese without translations.

Test the empty-family editor fallback.

fontFamilySettings.resolvedDefault.isEmpty verifies only the stored value. It does not verify that an editor with an empty fontFamily uses the existing monospaced system font. Add an editor-level assertion for fontFamily: "". The configured typography test covers only "Helvetica".

This follows the PR objective that an empty fontFamily preserves the current monospaced system font.

Apply the new line height before asserting the reset.

After configurePreviewTypography(... lineHeight: 1), call textView.applyCurrentPreviewLineHeight() before reading naturalStyle. The production update path configures typography and applies line height in separate calls. Without the apply call, this test does not verify the reset behavior.

This is based on the updateNSView call sequence in Sources/Panels/FilePreviewTextEditor.swift, Lines 73-126.

Exercise FilePreviewTextEditor.updateNSView in this synchronization test.

The test manually performs the synchronization operations inside coordinator.withPanelUpdate. It does not invoke updateNSView, which owns the contentNeedsUpdate decision and the stale-content guard. A regression in that production path can therefore pass this test. Use the actual scroll-view/document-view path or an integration helper that invokes updateNSView with stale editor content and fresh panel content.

This follows the production synchronization path shown in Sources/Panels/FilePreviewTextEditor.swift, Lines 73-126.

Review audit (re-checked against HEAD 10225a85cf, 2026-09-02)

All 18 inline review threads are resolved, and every thread has an explicit human reply. No actionable review or inline finding was created after the 10225a85cf push; newer top-level activity is limited to automated CLA/Cursor status comments, the documented recheck, and a maintainer review request.

The branch was rebased onto current origin/main (9e2dd50957) so the PR revision contains the same trusted CLA control-plane files as its base. This is an intentional security/mergeability trade-off: it rewrites the feature commit SHAs and adopts current main history, but avoids copying or weakening privileged policy files in the feature diff. git range-diff and non-build repository checks were re-run; the pre-existing detached vendor/bonsplit checkout remains at 1031b68621 and unstaged.

The native-locale disagreements follow the repository localization contract: new native Resources/Localizable.xcstrings keys are en/ja, while web/messages/*.json carries the broader locale set.

CI/review state at this audit: an earlier run for this exact head passed (CLA policy guard run 33572269091; CLA Assistant run 33572269060), but the newest attempts (CLA guard run 33572436741 attempt 2 and CLA Assistant run 33572436894 attempt 2) failed in the GitHub API lookup path under the repository-wide rate limit (Could not query the pull request / generic policy rejection), and their exact reruns failed the same way. Testbox, Socket, and Vercel-comment checks are green; the active branch ruleset requires CLA policy guard, so the latest required context is not green. A human approval is also now required; @lawrencecchen is requested and GitHub reports REVIEW_REQUIRED. Vercel preview contexts remain pending in the integration queue (advisory).

No local build, reload, xcodebuild, or E2E workflow was run because the continuation explicitly forbids launching any build; the AWS workspace had no current-head artifact to exercise without starting one. Consequently no current-head end-to-end app verification exists. The PR is intentionally not merged, and issue #10319 remains open pending a successful required-check rerun, human approval, and separately authorized runtime verification.

Review audit — re-checked at HEAD 5b3c0a8611 (September 7, 2026)

All 18 inline review threads are resolved and each has an explicit austinywang reply. The latest review/comment activity is September 1, 2026; no newer actionable review body or comment is unanswered, and no review is CHANGES_REQUESTED.

The branch is current with origin/main at 7d78b6e4cb. The rebase rewrote feature commit SHAs but preserves the current main security/CI history. During that rebase, the shared FilePreviewTextEditorLayout constants were restored in a dedicated, wired source file because current-main WindowAndDragTests still references that behavior. This is an intentional scope/mergeability trade-off: keep the feature branch current and preserve the existing test contract rather than duplicate constants at call sites.

The native-locale disagreements follow the repository localization contract: native Resources/Localizable.xcstrings additions are English/Japanese in this feature PR, while web message catalogs carry the broader locale set.

Validation at this HEAD:

  • check-pbxproj.sh, lint-pbxproj-test-wiring.sh (794 test files), check-package-resolved-policy.py, JSON parsing for all touched catalogs/schema, and git diff --check pass.
  • scripts/swift_file_length_budget.py is absent from both this checkout and origin/main; no Swift budget TSV was modified. Changed/new Swift files were manually checked; the new test and helper files remain below 500 lines.
  • Hosted focused run 34072913509 checked out this exact head but could not execute the selected test because the current-main test target fails first in untouched cmuxTests/CLILocalTmuxReviewRegressionTests.swift (LocalTmuxSessionIdentity, LocalTmuxSessionBinding, LocalTmuxCommandBuilder, LocalTmuxProcessRunner, and LocalTmuxSessionListParser are not visible). This is a baseline current-main test-target defect, not a file changed by this PR; no unrelated CLI target change was made.
  • PR-specific required checks are green. The two Vercel deployment contexts remain pending/advisory, so GitHub reports UNSTABLE despite all required CI checks passing.
