* Open cmd+clicked terminal links in cmux browser panel instead of system browser
Handle GHOSTTY_ACTION_OPEN_URL in the Ghostty action callback to intercept
link opens. Uses preferredBrowserTargetPane to reuse an existing right-side
pane, falling back to a new horizontal split.
* Use tab-specific manager for OPEN_URL action
Use tabManagerFor(tabId:) instead of the active-window tabManager so the
lookup succeeds when the surface belongs to a different window context.
* Add "+" menu button to horizontal tab bar for new terminal/browser tabs
Adds a "+" button to the tab bar (next to split buttons) that shows a
dropdown menu with "New Terminal ⌘T" and "New Browser ⌘⇧L" options.
- Uses native NSButton + NSMenu so the icon matches the split buttons
- Menu appears below the button
- Routes tab creation through new didRequestNewTab delegate method

* Fix multi-workspace drag/drop, WebView click focus, and add regression tests
- Wire bonsplit isInteractive to workspace active state so inactive
workspace NSViews are hidden from AppKit event routing
- Add CmuxWebView.mouseDown notification for browser panel focus
tracking (AppKit delivers clicks to WKWebView, not SwiftUI overlays)
- Add multi-workspace focus regression test covering isHidden fix,
rapid workspace switching, and browser panel focus routing
* Bump version to 1.36.0
The 3-second safety net that posts a synthetic mouseUp to break out of
NSTextView's stuck tracking loop was dispatched on the main queue. Since
super.mouseDown blocks the main thread in the tracking loop, the timeout
could never fire. Use a background queue instead (NSApp.postEvent is
thread-safe). Use DispatchWorkItem.isCancelled for atomic cancellation.
* 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.
- Sidebar now shows git branch, listening ports, log entries, progress bars, and status pills with expand/collapse
- Fix localhost/127.0.0.1 URL parsing by checking before generic URL(string:) which misinterprets the scheme
- Remove custom Keychain distinct ID in favor of PostHog SDK's built-in anonymous ID
- browser open now defaults to caller's workspace via CMUX_WORKSPACE_ID env var
- Improve CLI help text for environment variables
- Change Cmd+[/] from workspace history navigation to browser back/forward
(only when focused surface is a browser, no-op on terminal)
- Add WKUIDelegate with createWebViewWith to handle target=_blank links
- Add decidePolicyFor check for targetFrame==nil and cmd+click modifier
to open links in new browser surface in the same pane
- Override willOpenMenu in CmuxWebView to rename "Open Link in New Window"
to "Open Link in New Tab"
- Add E2E test for browser back/forward via socket and Cmd+[/] shortcuts
Instead of creating a merged config directory and injecting
CLAUDE_CONFIG_DIR on every terminal spawn, place a thin wrapper
script at Resources/bin/claude that intercepts claude invocations
to inject --session-id and --settings flags. This eliminates
blocking I/O on terminal creation and removes config management
complexity.
- Add Resources/bin/claude wrapper script with hook injection
- Add shell integration PATH fix (re-prepend after .zshrc/.bashrc)
- Add transcript reading for richer stop notifications
- Add set_status/clear_status to notifications socket allowlist
- Add Settings toggle to disable Claude Code integration
- Update docs to reflect automatic integration approach
- Unset CLAUDECODE env var to avoid nested session detection
Add THIRD_PARTY_LICENSES.md as a bundled resource so it ships inside
the .app bundle. Add a "Licenses" button to the About panel that opens
a scrollable window displaying the file contents.
* 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
## Screenshot Command
- Add 'screenshot' command to TerminalController for in-app window capture
- Returns OK with screenshot ID and path
## Other
- Add tests/visual_output/ and tests/visual_report.html to .gitignore
* Add browser title subscription and set tab height to 30px
- 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
- Add debug socket helpers: set_shortcut + simulate_shortcut for tests
- Convert browser goto_split/keybind tests to socket-based injection (no osascript)
- Bump bonsplit for drag-to-split fixes
* Fix split layout collapse and harden socket pane APIs
* Stabilize OSC 99 notification test timing

* Update ghostty submodule
* Fix terminal focus/render stalls after split churn
* Fix nested split collapsing existing pane
* Fix nested split collapse + stabilize new-surface focus
* Update bonsplit submodule

* Remove PROJECTS.md
* 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
* Match browser globe tab icon size
* Bonsplit: tab min width 48 and tighter close button
* Bonsplit: smaller tab title font
* 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.
* Update bonsplit submodule
* WIP: improve split close stability and UI regressions
* Close terminal panel on child exit; hide terminal dirty dot
* Fix split close/focus regressions and stabilize UI tests
* Add unread Dock/Cmd+Tab badge with settings toggle
* Fix browser-surface shortcuts and Cmd+L browser opening
* Snapshot current workspace state before regression fixes
* Update bonsplit submodule snapshot

* Add terminal file drop e2e regression test
* Add v2 browser API, CLI ref resolution, and surface move/reorder test suites
* Add unit tests for shortcut hints, workspace reorder, drop planner, and update UI test stabilization
* Add cmux-debug-windows skill with snapshot script and agent config
* Update project docs: mark browser parity and move/reorder phases complete, add parallel agent workflow guidelines
* Update bonsplit submodule: re-entrant setPosition guard, tab shortcut hints, and moveTab/reorderTab API
* Add browser agent UX improvements: snapshot refs, placement reuse, diagnostics, and skill docs
- Upgrade browser.snapshot to emit accessibility tree text with element refs (eN)
- Add right-sibling pane reuse policy for browser.open_split placement
- Add rich not_found diagnostics with retry logic for selector actions
- Support --snapshot-after for post-action verification on mutating commands

- Default CLI --id-format to refs-first (UUIDs opt-in via --id-format uuids|both)
- Format legacy new-pane/new-surface output with short surface refs
- Add skills/cmuxterm-browser/ and skills/cmuxterm/ end-user skill docs
- Add regression tests for placement policy, snapshot refs, diagnostics, and ID defaults
* Update bonsplit submodule: keep raster favicons in color when inactive
* Fix muted traffic lights and sidebar texture discontinuity
Move background blur and tint overlays back into contentView (from
themeFrame) to eliminate the two-texture sidebar issue on older macOS.
Use layer.zPosition = -1000 to prevent SwiftUI subview reordering from
visually covering terminal content, and PassthroughBlurView/PassthroughView
subclasses to ensure mouse events pass through.
* Bump version to 1.26.0
Fix blank terminal on macOS 26 and macOS 15:
- Add macOS 26 guard to two additional code paths that set window non-opaque
- Fix NSVisualEffectView z-order: add to themeFrame instead of contentView
- Align sidebarBlendMode defaults between @AppStorage and UserDefaults
- Add read_screen socket command and blank screen regression test
- Add reloads.sh staging script
* Sidebar status as text + detect git HEAD changes instantly
- Replace sidebar status pills with plain text + show more/less toggle
for a cleaner, more readable sidebar layout
- Watch .git/HEAD mtime in zsh precmd to detect branch changes from
aliases (gco), tools (gh pr checkout), etc. without waiting for the
3s polling interval
- Fix NSImage shared instance mutation in DraggableFolderNSView by
copying before resizing to prevent layout side-effects
- Fix set_status --tab flag being swallowed by -- stop token via
new parseOptionsNoStop parser
- Update sidebar test to cover alias-based branch switching
* Append status text to notification body automatically
When creating notifications, include the tab's current status entries
in the notification body so users see context (e.g. git branch, ports)
alongside the notification message.
* Add screenshot to README
`surfaceConfig.env_vars` are overrides layered on top of Ghostty's
default subprocess environment. Starting the env map from
`ProcessInfo.processInfo.environment` re-introduced variables that
Ghostty intentionally strips (e.g. LANGUAGE, Xcode DYLD vars),
bypassing its env filtering.
Start with an empty map and add `getenv()` fallbacks for PATH, SHELL,
ZDOTDIR, and GHOSTTY_RESOURCES_DIR so critical values are still
resolved without leaking the full app environment.
- Restore real ZDOTDIR early in zsh startup so HISTFILE uses user history\n- Preserve user ZDOTDIR without treating Ghostty injected ZDOTDIR as user\n- Add regression tests and terminfo overlay for bright colors
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.
@Published fires on willSet, so the Combine sink measured fittingSize
while SwiftUI still saw the old state (idle/EmptyView), getting 0x0.
Defer measurement to next run loop cycle so SwiftUI processes the
new state before we read fittingSize.
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.
The transparency setup (non-opaque window + clear subview backgrounds)
required for the glass effect breaks SwiftUI content rendering on
macOS 26. Disable background glass when NSGlassEffectView is available
until a proper macOS 26 implementation is found.
* Fix zsh ZDOTDIR wrapper + log parsing with -- messages
* Fix CI race condition: serialize self-hosted builds with concurrency group
Two workflows racing on the same self-hosted runner caused DerivedData
corruption (release's rm -rf nuked DerivedData while CI was building).
Add shared concurrency group and scope DerivedData cleanup to project.
