* Add i18n infrastructure with String Catalog and Japanese translations
Introduce String Catalog (.xcstrings) for localization support:
- Localizable.xcstrings: 195 UI string entries with en and ja translations
- InfoPlist.xcstrings: Info.plist strings (microphone usage, Finder menu items)
- project.pbxproj: add xcstrings to build phase and ja to knownRegions
* Replace hardcoded UI strings with String(localized:defaultValue:)
Migrate all user-facing strings across 11 source files to use
String(localized:defaultValue:) API (macOS 13+). Each string references
a key in Localizable.xcstrings, with the English text preserved as
defaultValue for fallback.
Files modified:
- KeyboardShortcutSettings: 28 shortcut labels
- SocketControlSettings: mode names and descriptions
- TabManager: placement labels, color names, close dialogs
- BrowserPanel/BrowserPanelView: error pages, context menus, tooltips
- UpdateViewModel/UpdatePopoverView/UpdatePill: update UI states
- NotificationsPage: notification panel labels
- SurfaceSearchOverlay: search bar placeholder and tooltips
- AppDelegate: menus, dialogs, command palette items
* Fix localization gaps from review feedback
Address review comments from CodeRabbit, Greptile, and Cubic Dev AI:
- Use interpolated String(localized:) instead of concatenation for
version/progress strings in UpdateViewModel
- Localize remaining hardcoded strings in AppDelegate: window labels,
rename dialog, status menu items, unread notification count
- Localize insecure HTTP alert body in BrowserPanel
- Add 12 new entries to Localizable.xcstrings with Japanese translations
* Fix String(localized:defaultValue:) keys to use StaticString
The localized: parameter requires StaticString when defaultValue: is
used. Move string interpolation from the key to defaultValue only,
and revert maxWidthText to plain strings since they are only used for
layout width calculation.
* Localize remaining UI strings across all source files
Add String(localized:defaultValue:) to all user-facing strings in:
- cmuxApp.swift: settings screen, menus, about panel, dialogs (~180 strings)
- ContentView.swift: command palette, sidebar context menu, dialogs (~200 strings)
- Workspace.swift: rename/move/close tab dialogs, tooltips (~20 strings)
- UpdateTitlebarAccessory.swift: titlebar tooltips, notifications popover (~10 strings)
- TerminalNotificationStore.swift: notification permission dialog (4 strings)
- CmuxWebView.swift: browser context menu items (2 strings)
- AppDelegate.swift: CLI install/uninstall alerts (6 strings)
Add 418 new entries to Localizable.xcstrings with Japanese translations.
Extract sidebar context menu into separate @ViewBuilder to fix Swift
type-checker timeout in large body.
Fix xcstrings format specifiers for interpolated strings (%lld, %@).
Total: 624 localization entries covering the full UI.
* Address review feedback: fix missing localizations and terminology
- Localize javaScriptDialogTitle URL branch in BrowserPanel
- Localize cantReach error message in BrowserPanel
- Localize close other tabs dialog message in TabManager
- Localize workspace accessibility label in ContentView
- Fix unread notification singular/plural (split into two keys)
- Fix insecure connection apostrophe inconsistency (unify to U+2019)
- Rename socketControl.fullOpen.description to socketControl.allowAll.description
- Remove dead code: renameTargetNoun function
- Fix terminology inconsistencies in xcstrings:
- Unify "Developer Tools" to デベロッパツール
- Unify "Jump to Latest Unread" phrasing
- Unify "Flash Focused Panel" terminology
- Fix dialog.enableNotifications.notNow translation
* fix: address remaining PR 819 review feedback
* fix: use a single localized key for close-other-tabs
* fix: avoid inflection markup in close-other-tabs message
* Address review feedback: localize tooltip, fix subtitle concat, unify keys
- Localize menubar tooltip unread count (hardcoded English -> localized)
- Replace subtitle string concatenation anti-pattern with single localized
keys containing interpolation placeholders
- Unify workspace fallback key to workspace.displayName.fallback
- Remove unused workspace.defaultName key from xcstrings
- Add Japanese translations for new tooltip and subtitle keys
Only enable .onHover tracking on TitlebarControlButton when the style
uses hoverBackground (e.g. pillGroup). Styles without a visible hover
background no longer install the tracking area, preventing the crash
on notification-bell hover.
Also switches the notifications anchor from .overlay to .background so
AppKit hit-testing no longer conflicts with the popover anchor view.
Includes regression test for the hover-tracking policy.
Fixes https://github.com/manaflow-ai/cmux/issues/537
The nightly build is now a distinct app called "cmux NIGHTLY" with
bundle ID com.cmuxterm.app.nightly, allowing side-by-side installation
with the stable release. The nightly appcast URL is baked into the
app's Info.plist by CI, so no in-app channel switching is needed.
- Nightly workflow: rename app to "cmux NIGHTLY", set bundle ID to
com.cmuxterm.app.nightly, hardcode nightly Sparkle feed URL, publish
DMG as cmux-nightly-macos.dmg
- Remove "Receive Nightly Builds" toggle from settings
- Remove UpdateChannelSettings enum and simplify feed URL resolution
to just use SUFeedURL from Info.plist
- Remove UpdateChannelSettingsTests (no longer applicable)
After a Sparkle auto-update relaunches cmux, the control socket stops
accepting connections because start() early-returns when isRunning is
true, without checking if the accept loop thread is actually alive.
- Add acceptLoopAlive flag to track accept loop thread liveness
- Fix start() early-return to also check acceptLoopAlive, so a dead
thread triggers full socket re-creation
- Break acceptLoop() after 50 consecutive accept() failures with 10ms
backoff instead of tight-spinning forever
- Clean up socket in applicationWillTerminate and
updaterWillRelaunchApplication for clean teardown before relaunch
In fullscreen mode, the NSTitlebarAccessoryViewController buttons are hidden
with the system titlebar. This adds SwiftUI-based fullscreen controls that
appear in the sidebar area (when visible) or inline in the custom titlebar
(when sidebar is hidden), reusing the existing TitlebarControlsView component.
- Track fullscreen state via window notifications and toggle controls visibility
- Hide original titlebar accessory (isHidden + alphaValue=0) in fullscreen
- Route notification popover anchoring through fullscreen controls view model
so both button clicks and keyboard shortcuts (Cmd+Shift+I) position correctly
- Add debug titlebar spacing slider for fine-tuning leading inset
* Fix terminal keys (arrows, Ctrl+N/P) swallowed after opening browser
After a browser panel is shown, SwiftUI's internal focus system activates
and its _NSHostingView starts consuming arrow keys and other non-Command
key events via performKeyEquivalent, preventing them from reaching the
terminal's keyDown handler.
Fix: In the NSWindow performKeyEquivalent swizzle, when GhosttyNSView is
the first responder and the event has no Command modifier, route directly
to the terminal's performKeyEquivalent — bypassing SwiftUI's view hierarchy
walk entirely.
Also clear stale browserAddressBarFocusedPanelId when a terminal surface
has focus, preventing Cmd+N from being eaten by omnibar selection logic
after focus transitions away from a browser.
Adds DEBUG-only keyboard event ring buffer (KeyDebugLog) that dumps to
/tmp/cmux-key-debug.log for diagnosing future key routing issues.
* Fix split focus and Cmd+Shift+N swallowed after opening browser
Split focus: capture the source terminal's hostedView before bonsplit
mutates focusedPaneId, so focusPanel moves focus FROM the old pane
instead of from the new pane to itself. Also retry ensureFocus when the
new terminal's view has no window yet (matching the existing retry
pattern for isVisibleInUI).
Cmd+Shift+N: after WKWebView has been in the responder chain, SwiftUI's
internal focus system can intercept Command-key events in the content
view hierarchy (returning true) without firing the CommandGroup action
closure. Fix by dispatching Command-key events directly to NSApp.mainMenu
when the terminal is first responder, bypassing the broken SwiftUI path.
Also add Cmd+Shift+N to handleCustomShortcut so it's customizable and
doesn't depend on SwiftUI menu dispatch at all.
* Unified debug event log: merge key/mouse/focus into /tmp/cmux-debug.log
- Delete KeyDebugLog, MouseDebugLog, klog(), mlog() from AppDelegate
- Replace all klog/mlog calls with dlog() (provided by bonsplit)
- Remove debugLogCallback wiring from Workspace
- Add focus change logging: focus.panel, focus.firstResponder,
split.created, focus.moveFocus
- Add import Bonsplit where needed for dlog access
- Fix stale drag state on cancelled tab drags (bonsplit submodule)
* Fix split focus stolen by re-entrant becomeFirstResponder during reparenting
During programmatic splits (Cmd+D / Cmd+Shift+D), SwiftUI reparents the old
terminal view, which fires becomeFirstResponder → onFocus → focusPanel for the
OLD panel, stealing focus from the newly created pane.
Add programmaticFocusTargetPanelId guard to suppress re-entrant focusPanel
calls for non-target panels during split creation.
Also document the unified debug event log in CLAUDE.md.
* Clear stale title/favicon when browser navigation fails
When a page fails to load (e.g. connection refused), the tab was still
showing the previous page's title and favicon. Now didFailProvisionalNavigation
resets pageTitle to the failed URL and clears faviconPNGData.
* Fix Cmd+N swallowed by browser omnibar and improve split focus suppression
- Only Ctrl+N/P trigger omnibar navigation, not Cmd+N/P (Cmd+N should
always create new workspace regardless of address bar focus)
- Move split focus suppression from workspace-level guard to source:
suppress becomeFirstResponder side-effects (onFocus + ghostty_surface_set_focus)
directly on the old GhosttyNSView during reparenting, preventing both
model-level and libghostty-level focus divergence
- Remove programmaticFocusTargetPanelId from Workspace.focusPanel
* Fix omnibar hang, WebView white flash, drag-over-browser, and idle CPU spin
- Omnibar: first click selects all without entering NSTextView tracking loop;
subsequent clicks have 3s synthetic mouseUp safety net to prevent hang
- WebView: set underPageBackgroundColor to match window so new browsers don't
flash white before content loads
- Drag/drop: register custom UTType (com.splittabbar.tabtransfer) in Info.plist
so WKWebView doesn't intercept tab drags; override registerForDraggedTypes
on CmuxWebView as belt-and-suspenders
- CPU: fix infinite makeFirstResponder loop in controlTextDidEndEditing by
checking both the text field and its field editor (the actual first responder)
Move GeometryReader from wrapping the entire VStack to wrapping only the
ScrollView so proxy.size.height reflects available height (minus pill),
preventing unnecessary scrollability that triggered macOS horizontal insets.
Also clamp update pill text width with maxWidth instead of fixed width so
it truncates gracefully at narrow sidebar widths and grows when wider, add
horizontal padding, left-align truncated text, and add debug menu item for
testing with long nightly version strings.
* Fix blank terminal after split operations and add visual tests
## Blank Terminal Fix
- Add `needsRefreshAfterWindowChange` flag in GhosttyTerminalView
- Force terminal refresh when view is added to window, even if size unchanged
- Add `ghostty_surface_refresh()` call in attachToView for same-view reattachment
- Add debug logging for surface attachment lifecycle (DEBUG builds only)
## Bonsplit Migration
- Add bonsplit as local Swift package (vendor/bonsplit submodule)
- Replace custom SplitTree with BonsplitController
- Add Panel protocol with TerminalPanel and BrowserPanel implementations
- Add SidebarTab as main tab container with BonsplitController
- Remove old Splits/ directory (SplitTree, SplitView, TerminalSplitTreeView)
## Visual Screenshot Tests
- Add test_visual_screenshots.py for automated visual regression testing
- Uses in-app screenshot API (CGWindowListCreateImage) - no screen recording needed
- Generates HTML report with before/after comparisons
- Tests: splits, browser panels, focus switching, close operations, rapid cycles
- Includes annotation fields for easy feedback
## Browser Shortcut (⌘⇧B)
- Add keyboard shortcut to open browser panel in current pane
- Add openBrowser() method to TabManager
- Add shortcut configuration in KeyboardShortcutSettings

- Subscribe to BrowserPanel.$pageTitle changes to update bonsplit tabs
- Update tab titles in real-time as page navigation occurs
- Clean up subscriptions when panels are removed
- Set bonsplit tab bar and tab height to 30px (in submodule)
* Fix socket API regressions in list_surfaces, list_bonsplit_tabs, focus_pane
- list_surfaces: Remove [terminal]/[browser] suffix to keep UUID-only format
that clients and tests expect for parsing
- list_bonsplit_tabs --pane: Properly look up pane by UUID instead of
creating a new PaneID (requires bonsplit PaneID.id to be public)
- focus_pane: Accept both UUID strings and integer indices as documented
* Fix browser panel stability and keyboard shortcuts
- Prevent WKWebView focus lifecycle crashes during split/view reshuffles
- Match bracket shortcuts via keyCode (Cmd+Shift+[ / ], Cmd+Ctrl+[ / ])
- Support Ghostty config goto_split:* keybinds when WebView is focused
- Add focus_webview/is_webview_focused socket commands and regression tests
- Rename SidebarTab to Workspace and update docs
* Make ctrl+enter keybind test skippable
Skip when the Ghostty keybind isn't configured or when osascript can't send keystrokes (no Accessibility permission), so VM runs stay green.
* Auto-focus browser omnibar when blank
When a browser surface is focused but no URL is loaded yet, focus the address bar instead of the WKWebView.
* Stabilize socket surface indexing
* Focus browser omnibar escape; add webview keybind UI tests
- Escape in omnibar now returns focus to WKWebView\n- Add UI tests for Cmd+Ctrl+H pane navigation with WebKit focused (including Ghostty config)\n- Avoid flaky element screenshots in UpdatePillUITests on the UTM VM
* Fix browser drag-to-split blanks and socket parsing
* Fix webview-focused shortcuts and stabilize browser splits
- Match ctrl/shift shortcuts by keyCode where needed (Ctrl+H, bracket keys)
- Load Ghostty goto_split triggers reliably and refresh on config load

* Remove bonsplit tab selection animation
* Ignore generated test reports
* Middle click closes tab
* Revert unintended .gitignore change
* Fix build after main merge
* Revert "Fix build after main merge"
This reverts commit 16bf9816d0856b5385d52f886aa5eb50f3c9d9a4.
* Revert "Merge remote-tracking branch 'origin/main' into fix/blank-terminal-and-visual-tests"
This reverts commit 7c20fb53fd71fea7a19a3673f2dd73e5f0c783c4, reversing
changes made to 0aff107d787bc9d8bbc28220090b4ca7af72e040.
* Remove tab close fade animation
* Use terminal.fill icon
* Make terminal tab icon smaller

* Show unread notification badge in bonsplit tabs and improve UI polish
Sync unread notification state to bonsplit tab badges (blue dot).
Improve EmptyPanelView with Terminal/Browser buttons and shortcut hints.
Add tooltips to close tab button and search overlay buttons.
* Fix reload.sh single-instance safety check on macOS
Replace GNU-only `ps -o etimes=` with portable `ps -o etime=` and
parse the dd-hh:mm:ss format manually for macOS compatibility.
* Centralize keyboard shortcut definitions into Action enum
Replace per-shortcut boilerplate with a single Action enum that holds
the label, defaults key, and default binding for each shortcut. All
call sites now use shortcut(for:). Settings UI is data-driven via
ForEach(Action.allCases). Titlebar tooltips update dynamically when
shortcuts are changed. Remove duplicate .keyboardShortcut() modifiers
from menu items that are already handled by the event monitor.
* Fix WKWebView consuming app menu shortcuts and close panel confirmation
Add CmuxWebView subclass that routes key equivalents through the main
menu before WebKit, so Cmd+N/Cmd+W/tab switching work when a browser
pane is focused. Fix Cmd+W close-panel path: bypass Bonsplit delegate
gating after the user confirms the running-process dialog by tracking
forceCloseTabIds. Add unit tests (CmuxWebViewKeyEquivalentTests) and
UI test scaffolding (MenuKeyEquivalentRoutingUITests) with a new
cmux-unit Xcode scheme.
* Update CLAUDE.md and PROJECTS.md with recent changes
CLAUDE.md: enforce --tag for reload commands, add cleanup safety rules.
PROJECTS.md: log notification badge, reload.sh fix, Cmd+W fix, WebView
key equiv fix, and centralized shortcuts work.
* Keep selection index stable on close
* Add concepts page documenting terminology hierarchy
New docs page explaining Window > Workspace > Pane > Surface > Panel
hierarchy with aligned ASCII diagram. Updated tabs.mdx and splits.mdx
to use consistent terminology (workspace instead of tab, surface
instead of panel) and corrected outdated CLI command references.

- Add regression tests for placement policy, snapshot refs, diagnostics, and ID defaults
* Update bonsplit submodule: keep raster favicons in color when inactive
Error 4005 (updater permission) with underlying code 10 (cache
directory creation failure) has the same root cause as 1003/1005:
the app isn't in Applications.
The pill never appeared because:
1. SwiftUI .frame(width:0, height:0) when idle poisoned fittingSize
2. AppKit constraints locked at 0x0 prevented expansion on state change
3. fittingSize always returned 0 due to active 0x0 constraints
Fix: Remove zero-frame from SwiftUI (always render at natural size,
use opacity only). Deactivate constraints before measuring fittingSize
so they don't clamp the measurement. Pass visibility to sizeToolbarItem
to set constraints to zero when idle or natural size when active.
NSHostingView with frame (0,0) won't layout SwiftUI content, so
fittingSize always returns 0 when transitioning from EmptyView.
Instead, always render the pill button and use opacity/frame(0)
to hide when idle. This ensures the hosting view always has content
to measure.
Errors from Sparkle were bypassing the minimum check display duration,
causing the error to appear instantly (1ms) without the user ever
seeing the "Checking for updates" state. Use setStateAfterMinimumCheckDelay
for errors too so the checking spinner shows for at least 2 seconds.
* Add sidebar blur effect with withinWindow blending
- Add NSVisualEffectView-based blur backdrop for sidebar
- Support withinWindow blending mode to blur terminal content behind sidebar
- Auto-switch to overlay layout when withinWindow mode is selected
- Add sidebar debug panel with material, blending, tint, and opacity controls
- Add preset options (HUD Glass, Popover Glass, etc.)
- Default to HUD Glass preset with withinWindow blur
* Simplify tab close button visibility and remove hover background
Show close button only on hover instead of when active/multi-selected.
Remove the hover background color from tabs for cleaner appearance.
* Add config reload support with notification system
- Add reloadConfiguration() methods for app-wide and per-surface reload
- Handle GHOSTTY_ACTION_RELOAD_CONFIG action from Ghostty
- Add ghosttyConfigDidReload notification for views to react
- TerminalSplitTreeView reloads GhosttyConfig on notification
- Add openConfigurationInTextEdit() helper
- Fix activeMainWindow() to correctly find main window
* Add custom tab titles and pinned tabs support
- Add customTitle and isPinned properties to Tab
- Separate process title from custom title with applyProcessTitle()
- Add setCustomTitle()/clearCustomTitle() for user-defined tab names
- Add togglePin()/setPinned() with automatic reordering
- Pinned tabs stay at the top, new tabs insert after pinned section
- moveTabToTop/moveTabsToTop respect pinned tab ordering
* Add --panel option to new-split command
- CLI: Parse --panel <id|index> option for new-split
- Controller: Resolve panel argument to split specific surface
- Return new panel UUID on successful split creation
* Fix notifications popover positioning with layout-aware anchor
- Use AnchorNSView with layout callback for reliable positioning
