Lineup

A focused, list-only macOS window switcher.

Lineup is a Cleyrop-maintained fork of DevSwitcher2, trimmed to a single, fast list view and made English-only. It lives in the menu bar and gives you two switchers:

• Same-app window switcher (default `⌘ + ``) — cycle the windows of the current app, with smart project-name extraction from window titles.
• App switcher (default ⌘ + Tab) — an enhanced Command-Tab across all apps.

Download

Via Homebrew:

brew install --cask cleyrop/lineup/lineup

Or grab the latest signed, notarized Lineup-<version>.dmg from the Releases page, open it, and drag Lineup into Applications. Either way, on first launch macOS asks for Accessibility permission — see Permissions.

What's different from DevSwitcher2

• List-only. The circular/radial layout, outer-ring styles and floating-item effects are removed — one clean list, less to configure, less to maintain.
• English-only. The Chinese localization and language picker are gone.
• Arrow-key navigation (issue #6) — while the switcher is open, use ↑ / ↓ to move through the list and Enter to activate, in addition to holding the modifier and the number keys.
• Windows from all Spaces (issue #7) — the same-app switcher lists the app's windows from every Space / desktop, not just the current one. Toggle it under Preferences → Advanced → Show Windows From All Spaces (on by default).

Build

Requires Xcode (macOS 13+ deployment target).

./scripts/build-macos.sh        # unsigned Lineup.app for local use

Or open Lineup/Lineup.xcodeproj in Xcode and run the Lineup scheme.

For signed/notarized release builds and the CI pipeline, see SIGNING.md.

Dev build alongside the release

The Debug configuration builds as a distinct app — bundle id com.cleyrop.lineup.dev, display name "Lineup Dev" — so it has its own TCC permissions and LaunchServices entry, completely separate from the installed release (com.cleyrop.lineup / "Lineup"). Grant Accessibility to "Lineup Dev" once and it persists across rebuilds without ever disturbing the release's grant.

./scripts/dev-install.sh        # build Debug, install ~/Applications/Lineup Dev.app, relaunch

Permissions

Lineup needs Accessibility permission (System Settings → Privacy & Security → Accessibility) to read and switch application windows. Screen Recording is optional — it's only used for live window previews; skip it if you use the app icon or initials display style. Both are shown with one-click grant buttons under Preferences → General → Permissions.
