* chore(claude-opus-4-6): From HN feedback: https://news.ycombinator.com/item?id=47...
* Centralize workspace auto-reorder into addNotification
Move moveTabToTop into TerminalNotificationStore.addNotification so all
notification paths (Ghostty actions, v2 API, control socket) respect the
reorder-on-notification setting, not just the two Ghostty action sites.

Adds a configurable host allowlist in Settings > Browser that controls
which terminal links open in the cmux embedded browser vs the system
default browser. Supports exact match and wildcard prefix patterns
(e.g. localhost, 127.0.0.1, *.localtest.me). Empty list preserves
existing behavior of opening all web links in cmux.

* 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).
* Fix CJK IME input not working (#118)
CJK (Korean, Japanese, Chinese) IME input was completely broken because
cmux never forwarded preedit/composition state to Ghostty's libghostty.
Root causes and fixes:
1. Missing preedit sync: Added syncPreedit() that calls
ghostty_surface_preedit() to notify Ghostty about IME composition
text. Called from setMarkedText, unmarkText, and after
interpretKeyEvents in keyDown.
2. Wrong composing flag: The composing flag on key events now correctly
accounts for when composition just ended (markedTextBefore was true
but markedText is now empty), preventing spurious deletions when
canceling composition.
3. Event interception during IME: Added early exits in
performKeyEquivalent, the NSWindow swizzle, and the local event
monitor (handleCustomShortcut) to avoid stealing key events while
IME has active marked text.
4. IME popup positioning: firstRect(forCharacterRange:) now uses
ghostty_surface_ime_point() for accurate cursor-relative positioning
of the IME candidate window.
* Add regression tests for CJK IME composition (#118)
31 tests covering Korean, Japanese, and Chinese IME input scenarios:
- Korean jamo combining: ㅎ -> 하 -> 한 composition lifecycle
- Chinese pinyin: multi-letter marked text and candidate selection
- Japanese hiragana-to-kanji: romaji -> hiragana -> kanji conversion
- insertText correctly commits composed text and clears marked state
- unmarkText properly clears composition state (idempotent)
- performKeyEquivalent returns false during active composition for
all key types (plain, shift, space, return, escape)
- Shortcut bypass: hasMarkedText gates the handleCustomShortcut bypass
- Multi-syllable sequences, backspace correction, and rapid transitions
- keyTextAccumulator lifecycle tests
Also adds #if DEBUG test accessors for keyTextAccumulator on
GhosttyNSView to enable unit testing the accumulator path.
Use GhosttyFlashOverlayView (hitTest returns nil) instead of plain
NSView so the overlay doesn't steal drag/mouse routing.

The drop placeholder rendered in SwiftUI was hidden behind the
portal-hosted terminal surface. Add an AppKit overlay directly on
GhosttySurfaceScrollView driven by a new paneDropZone environment key
from Bonsplit so it renders above the Metal layer.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Switch from ghostty_surface_key (key event path) to ghostty_surface_text
(paste path) for file drops, matching upstream Ghostty. This triggers
bracketed paste mode and eliminates the lag on drop.
Remove makeFirstResponder calls from insertDroppedPasteboard and
handleDroppedURLs so dropping a file doesn't steal keyboard focus from
the currently focused terminal.
Nested NSHostingController layers (from bonsplit's SinglePaneWrapper)
prevent AppKit's NSDraggingDestination routing from reaching terminal
views. Install a transparent FileDropOverlayView on the window's theme
frame that intercepts file drags and forwards drops to the GhosttyNSView
under the cursor. Mouse events pass through via a hide-send-unhide
pattern.
Fix y-axis inversion in split targeting: hitTest expects coordinates in
the receiver's superview's coordinate system, not the receiver's own.
Converting to contentView's coords flipped y because NSHostingView is
flipped, causing top/bottom split drops to land in the wrong terminal.
Also adds bonsplit onFileDrop API, PaneDragContainerView, and
drop_hit_test socket command for testing coordinate-to-terminal mapping.
* 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.
* 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)
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
