* Fix terminal Cmd zoom routing for Ghostty focus descendants (#383)
* Inherit new terminal zoom from last terminal context
Prefer pane-selected terminal as Ghostty config inheritance source when creating splits/new terminals, then focused/fallback terminals. This preserves runtime zoom/font size when opening the next terminal.
* Fix terminal zoom inheritance across split/tab/workspace creation
* Add tab color feature to sidebar workspaces
Lets users assign a custom background color to any sidebar workspace tab
via a right-click "Tab Color" submenu. The primary motivation is working
across multiple projects simultaneously — coloring tabs by project makes
it instant to visually locate the right workspace without reading the title.
- Workspace: adds `customColor: String?` (@Published hex string) and
`setCustomColor()` setter
- TabManager: adds `setTabColor(tabId:color:)` convenience method
- ContentView: 16-color dark palette (all luminance < 0.30, white text
always readable), `Color(hex:)` extension, `coloredCircleImage(hex:)`
helper to render bitmapped NSImage circles (needed because macOS menus
strip SwiftUI foregroundColor from SF Symbols), updated `backgroundColor`
to use custom color at full/70%/35% opacity for active/inactive/
multi-selected states, "Tab Color" submenu in context menu with
"Clear Color" option, and a 1.5pt `Color.primary` border overlay on
the active tab for clear selection indication when custom colors are set
* Add workspace tab color schemes with settings and debug toggles
* Remove Kelly scheme and keep only original tab color palette
* Preserve neutral grayscale when brightening tab colors
* Harden UpdatePill UI test polling timeouts

* Fix manual unread clear race on focused tab
* Add mark-as-read tab action and show ring for manual unread
* Flash then clear manual unread on tab focus
* Sidebar ports on own line, wider sidebar, CMUX_PORT env vars
- Move listening ports to dedicated sidebar row (removed from branch/directory line)
- Allow sidebar to resize up to 2/3 of screen width (was capped at 360px)
- Add CMUX_PORT, CMUX_PORT_END, CMUX_PORT_RANGE env vars per workspace
- Each workspace gets a dedicated port range (default: base 9100, range 10)
- Add settings UI for port base and range size
- Add portOrdinal to Workspace, monotonic counter in TabManager
Closes#129
* Make port ordinal counter static to avoid overlap across windows
Each window creates its own TabManager, so a per-instance counter
would reset and reuse port ranges. Making it static ensures unique
ranges across all windows.
* Fix portOrdinal race: pass through Workspace init instead of setting after
The first TerminalPanel is created inside Workspace.init, so setting
portOrdinal after init returns meant the initial terminal always got
ordinal 0. Pass portOrdinal as an init parameter and set it before
the TerminalPanel is created.
* Fix P2/P3: snapshot port settings at surface creation, use window screen for sidebar cap
P2: Port base/range are now snapshotted on TerminalSurface when the
panel is created, so changing settings mid-session won't cause
inconsistent CMUX_PORT values across terminals in the same workspace.
P3: Sidebar max width now uses NSApp.keyWindow?.screen instead of
NSScreen.main, so multi-monitor setups get the correct 2/3 cap for
the display the window is actually on.
* Fix P1: snapshot port base/range once per app session, not per panel
Port base and range size are now static properties on TerminalSurface,
initialized once from UserDefaults at first access. This prevents
overlapping port ranges across workspaces when settings are changed
mid-session (e.g., workspace 1 with range=10 at 9110-9119, then
range changed to 5, workspace 2 would overlap at 9110).
* Move port scanning from shell to app-side with batching
Replace per-shell `ps -axo + lsof` scanning with a centralized
PortScanner singleton in the app. Each shell now sends lightweight
`report_tty` (once per session) and `ports_kick` (on preexec/precmd)
socket messages. The app coalesces kicks across all panels and runs a
single `ps -t <ttys> + lsof -p <pids>` covering every active panel.
Also fixes a macOS 26 Tahoe regression where `getsockopt(LOCAL_PEERPID)`
returns ENOTCONN on accepted sockets when the peer disconnects before
the handler thread starts. This was silently breaking ALL socket
commands sent via ncat --send-only. The fix captures the peer PID in
the accept loop immediately after accept(), and falls back to
LOCAL_PEERCRED (uid check) when the PID lookup fails.
* Fix PR review feedback: burst timing and auth comment clarity
- P2: burstDelays were accumulating (0.5+1.5+3+... = ~22.5s) instead of
firing at absolute offsets from burst start. Now uses burstStart anchor
so scans fire at 0.5s, 1.5s, 3s, 5s, 7.5s, 10s as intended.
- P1: Clarify LOCAL_PEERCRED fallback rationale — same security boundary
as socket file permissions (0600), does not widen attack surface.
Long-lived connections still get full descendant check via LOCAL_PEERPID.
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 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)
