# BusyMirror — Agent Reference
> This file is written for AI coding agents. It assumes you know nothing about the project.
## Project Overview
**BusyMirror** is a macOS menu-bar utility that mirrors calendar events from a source calendar into one or more target calendars, creating busy-placeholder events so availability stays consistent across accounts and devices.
It is a single-platform macOS app written in **Swift 5** and **SwiftUI**, using **EventKit** to read and write calendar data. The app runs as a menu-bar-only app (`LSUIElement`) with no Dock icon.
Key capabilities:
- Manual or route-driven multi-source mirroring
- Privacy modes: hide details (placeholder title) or mark events Private server-side (best-effort)
- DRY-RUN mode to preview changes without writing
- Scheduled headless runs via a self-installed `launchd` LaunchAgent
- Settings autosave/restore, plus Import/Export JSON
- CLI support for headless/scripted runs
## Technology Stack
| Layer | Technology |
|-------|------------|
| Language | Swift 5.0 |
| UI Framework | SwiftUI + AppKit (menu bar, panels) |
| Calendar API | EventKit (`EKEventStore`, `EKEvent`, `EKCalendar`) |
| Persistence | `UserDefaults` (JSON-encoded settings), `@AppStorage` |
| Scheduling | `launchd` / `launchctl` (user LaunchAgent) |
| Build System | Xcode project (`BusyMirror.xcodeproj`) + Makefile |
| Target OS | macOS 15.5+ |
| Signing | Ad-hoc (`CODE_SIGN_IDENTITY = "-"`) — not notarized |
No external Swift Package Manager dependencies are used. The project is self-contained.
## Project Structure
```
BusyMirror/
├── BusyMirrorApp.swift # App entry point; defines Window + MenuBarExtra
├── ContentView.swift # Main UI, mirror engine, settings, CLI, scheduling (≈2600 lines)
├── MenuBarSupport.swift # `BusyMirrorAppController` (state coordinator) + menu bar view
├── Info.plist # LSUIElement, calendar usage descriptions
├── BusyMirror.entitlements # App sandbox + calendar access entitlement
└── Assets.xcassets/ # AppIcon set and accent color
BusyMirror.xcodeproj/ # Xcode project
BusyMirrorTests/ # Empty (no tests implemented)
BusyMirrorUITests/ # Empty (no tests implemented)
```
**Architecture note:** nearly all business logic lives inside `ContentView.swift`. This includes:
- SwiftUI view body and subviews
- EventKit mirror engine (read, deduplicate, merge, create/update/delete)
- Settings serialization/deserialization
- CLI argument parsing
- `launchd` LaunchAgent installation/removal
- Logging to file and UI
When making changes, be aware that `ContentView.swift` is a large monolithic file. Extracting helpers is fine, but keep the existing data flow ( `@EnvironmentObject`, `@AppStorage`, `@State`) intact.
## Build and Release Commands
### Makefile targets
```bash
make build-debug # Debug build via xcodebuild
make build-release # Release build via xcodebuild
make sign-app # Ad-hoc sign the Release app (strip xattr, codesign)
make app # Verify signed app exists
make package # Create BusyMirror-<version>-macOS.zip + .sha256
make clean # Clean derived data
```
Built products:
- Unsigned release: `build/DerivedData/Build/Products/Release/BusyMirror.app`
- Signed release: `build/ReleaseSigned/BusyMirror.app`
### Xcode
1. Open `BusyMirror.xcodeproj`.
2. Select **BusyMirror** scheme → **My Mac**.
3. **Product → Build** (or **Archive** for distribution).
### Versioning
- `MARKETING_VERSION` and `CURRENT_PROJECT_VERSION` live in `project.pbxproj`.
- The Makefile extracts `MARKETING_VERSION` automatically for ZIP naming.
- Update both Debug and Release build configurations when bumping the version.
## Code Style Guidelines
- **Language:** all code, comments, and user-facing strings are in **English**.
- **Concurrency:** `@MainActor` is required on methods that mutate SwiftUI `@State` or call EventKit on the main thread. The compiler enforces strict concurrency.
- **Formatting:** standard Swift style (4-space indentation). No external linter is configured.
- **Logging:** use the `log(_:)` method inside `ContentView`; it appends to both the on-screen log editor and the persistent file log (`~/Library/Logs/BusyMirror/BusyMirror.log`).
- **Error handling:** EventKit errors are caught and logged; they must never crash the app. The file logger swallows its own errors silently.
## Testing
- **There are no implemented tests.** `BusyMirrorTests/` and `BusyMirrorUITests/` exist as Xcode targets but contain no source files.
- When adding logic, prefer extracting pure functions (e.g., block merging, gap calculation, filter logic) so they can be unit-tested later.
- Manual testing checklist for releases:
1. Grant Calendar permission.
2. Select a source and target, run DRY-RUN, verify log output.
3. Toggle WRITE and run Mirror Now; verify placeholders appear in the target calendar.
4. Move a source event and re-run; verify the placeholder updates.
5. Test Cleanup Placeholders (dry-run and write).
6. Add a route, install a schedule, verify the LaunchAgent plist is created in `~/Library/LaunchAgents/`.
7. Trigger a menu-bar sync and confirm the window opens if not visible.
## Security and Privacy Considerations
- **Calendar data:** the app reads and writes the users calendars via EventKit. It must handle permission denial gracefully.
- **Sandbox:** the app uses the macOS app sandbox (`com.apple.security.app-sandbox`) and the `com.apple.security.personal-information.calendars` entitlement.
- **Signing:** releases are ad-hoc signed only (`codesign --sign -`). They are **not notarized**. Gatekeeper may block the app on first launch; users may need to right-click → Open.
- **Private events:** the "Mark Private" feature uses Objective-C runtime tricks (`perform(Selector:)`, KVC `setValue:forKey:`) because EventKit does not expose a public privacy API. This is best-effort and may silently fail on some calendar providers (e.g., some Exchange configurations).
- **Loop guard:** a `sessionGuard` set prevents mirroring an event into the same target twice in one run, and prefix-based detection (`titlePrefix`) prevents re-mirroring already-mirrored placeholders.
- **Logging:** log files are written to the users `~/Library/Logs/BusyMirror/`. No log data is transmitted externally.
## CLI and Scheduling
The binary supports headless execution:
```bash
# Run saved routes (used by the LaunchAgent)
BusyMirror.app/Contents/MacOS/BusyMirror --run-saved-routes --write 1 --exit
# Manual route via 1-based UI indices
BusyMirror.app/Contents/MacOS/BusyMirror --routes "1->2,3" --write 1 --exit
```
Relevant flags: `--privacy`, `--copy-notes`, `--all-day`, `--days-forward`, `--days-back`, `--merge-gap-hours`, `--mode`, `--exclude-titles`, `--exclude-organizers`, `--cleanup-only`, `--exit`.
Scheduled runs are implemented by generating a `launchd` plist in `~/Library/LaunchAgents/com.cqrenet.BusyMirror.saved-routes.plist` and bootstrapping it with `launchctl`. The app removes and re-bootstraps the agent on every "Install Schedule" click.
## Key Files to Know
| File | Purpose |
|------|---------|
| `BusyMirror/ContentView.swift` | UI, business logic, mirror engine, settings, CLI, scheduling |
| `BusyMirror/BusyMirrorApp.swift` | App struct, window scene, menu-bar extra |
| `BusyMirror/MenuBarSupport.swift` | `@MainActor` app controller + menu bar SwiftUI view |
| `BusyMirror/Info.plist` | `LSUIElement`, calendar usage descriptions |
| `BusyMirror/BusyMirror.entitlements` | Sandbox + calendar entitlement |
| `Makefile` | Reproducible build, sign, and package targets |
| `CHANGELOG.md` | Release notes (human-readable) |
| `ROADMAP.md` | Planned features |
## Notes for Agents
- Do **not** add third-party dependencies unless the user explicitly asks. The project intentionally has zero external packages.
- If you refactor `ContentView.swift`, preserve `@AppStorage` keys and `UserDefaults` keys exactly; users have existing settings on disk.
- The mirror engine is tightly coupled to SwiftUI state. Extract helpers for testability, but do not break the `@MainActor`/`@State` flow without careful review.
- When modifying build settings, update both Debug and Release configurations in `project.pbxproj`, and update `CHANGELOG.md` if the change is user-visible.
- Do not run `git commit`, `git push`, or similar operations unless explicitly asked.
