The decide job already skips when main HEAD matches the nightly tag,
so this only builds when there are actual changes. Hourly means users
get nightly updates within an hour of merging to main.
Follows the same pattern as AppIcon-Debug (orange DEV banner) but with
a purple banner and "NIGHTLY" text. The nightly CI workflow now passes
ASSETCATALOG_COMPILER_APPICON_NAME=AppIcon-Nightly to xcodebuild so
the nightly app gets its own distinct icon.
Includes scripts/generate_nightly_icon.py for regenerating the icons
from the production AppIcon source files.
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- Remove UpdateChannelSettingsTests (no longer applicable)
Root cause: update-homebrew.yml triggered on release:published, which fires
before softprops/action-gh-release finishes uploading assets. The workflow
downloaded a 404 page instead of the DMG and committed its SHA.
Fix:
- Change trigger from release:published to workflow_run (fires after the
release workflow completes, guaranteeing assets are uploaded)
- Add download validation with retries and file size checks
- Add SHA verification step before committing to the cask
- Add homebrew cask update to build-sign-upload.sh for local releases
- Add regression test (tests/test_homebrew_sha.sh)
- Update /release and /release-local skills with homebrew verification steps
Fixes#110
Remove -Dxcframework-target=native from CI and release workflows,
defaulting to universal (matching upstream ghostty). The native target
produces a macos-arm64 xcframework slice that causes Xcode to link the
final binary differently (~70KB more __text), resulting in menubar and
right-click lag on M1 Max. The arm64 static libraries are byte-for-byte
identical between native and universal builds - the difference is purely
in how Xcode resolves the xcframework slice.
The -Dxcframework-target flag controls platform slices (native=macOS
only, universal=macOS+iOS), not CPU microarchitecture. Removing it
caused CI to attempt iOS builds which fail due to missing Metal
iOS toolchain on the runner.
* Fix zsh git branch refresh race after cwd change
* Clarify intentional duplicate cwd check in git refresh path
* Add Metal Toolchain download step to CI and release workflows
Fixes build failure when compiling Metal shaders for iOS xcframework
targets — the self-hosted runner needs `xcodebuild -downloadComponent
MetalToolchain` installed before `xcrun metal` can run.

The self-hosted runner (M4 Mac Mini) was building GhosttyKit with
-Dxcframework-target=native, producing M4-tuned binaries. This caused
menubar and right-click lag on M1 machines. Dropping the flag defaults
to universal, which works well across all Apple Silicon chips.
Hardened runtime's library validation was verifying every dylib on load,
causing noticeable UI lag. Add entitlements file with
disable-library-validation to fix while keeping notarization support.
* 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

* Remove bonsplit tab-switch crossfade
* 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

* 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

- 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
Add "Failed to activate application" to the retry/skip patterns so
the self-hosted runner gracefully skips UI tests when the app can't
come to foreground (Running Background state).
- CI: replace Node/npm with Bun
- Add view-transition animations for theme toggle
- Set html background for flash-free theme switches
- UI refinements to download button, brew command, and layout
- Replace package-lock.json with bun.lock
- Minimal centered layout with Geist sans font
- Typing animation cycling through agent names
- Light/dark mode toggle via next-themes
- Download for Mac button linking to latest DMG
- Feature list, GitHub + Docs footer links
- Meta tags and Open Graph for SEO
- CI: add web typecheck job (tsc --noEmit)
hdiutil produces a basic layout. npm create-dmg (sindresorhus) gives
large centered icons with proper spacing. The blank Applications icon
is a macOS 26 rendering issue that affects both approaches.
create-dmg (brew) uses AppleScript/Finder for icon positioning which
times out on headless CI. Switch to hdiutil with Applications symlink
for reliable CI builds.
Switch from npm create-dmg (sindresorhus) to brew create-dmg
(create-dmg/create-dmg) which properly renders the Applications
folder symlink icon with explicit layout control.
* 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.
Root cause: INFOPLIST_KEY_ build setting prefix only works for Apple-recognized
keys (CF*, NS*, LS*), not custom keys like SUPublicEDKey. The key was never
being added to Info.plist, so generate_appcast silently skipped EdDSA signing
(no public key in app = nothing to match against).
Fix:
- Derive public key from private key at build time using CryptoKit
- Use PlistBuddy to inject SUPublicEDKey and SUFeedURL after build
- Add sign_update fallback in appcast script if generate_appcast skips signing
- Add base64 padding normalization for key handling
SPARKLE_PUBLIC_KEY was set as a shell env var but Xcode needs it passed
as a build setting argument. Without SUPublicEDKey in Info.plist, Sparkle
silently ignores updates.
