BusyMirror

BusyMirror mirrors meetings between your calendars so your availability stays consistent across accounts/devices.

What it does (current)

• Route-driven mirroring (multi-source): define Source → Targets routes and run them in one go.
• Manual selection mirroring: pick a source and targets in the UI and run.
• Two privacy modes:
  • Private (hide details): mirrors placeholders with prefix + placeholder title (e.g., "🪞 Busy").
  • Mark Private: mirrors prefix + real title, but marks events Private on supported servers (best-effort).
• DRY-RUN mode: see what would be created/updated/deleted without writing.
• Overlap modes: allow, skipCovered, fillGaps.
• Merge adjacent events with a configurable gap.
• Time window controls (days back/forward) and Work Hours filter.
• Accepted-only filter (mirror your accepted meetings only).
• Cleanup of placeholders, including auto-delete of mirrors whose source disappeared.
• Prefix-based tagging and loop guards to prevent re-mirroring mirrors.
• Settings: autosave/restore, Import/Export JSON.

Why

Use one calendar’s confirmed meetings to block time in other calendars (e.g., corporate iPad vs. personal devices).

Build (macOS)

Option A — Xcode

1. Open BusyMirror.xcodeproj in Xcode.
2. Select the BusyMirror scheme → My Mac.
3. Product → Build.
4. Product → Archive → Distribute App → Copy App (no notarization) to export a .app (or ZIP it for sharing).

Option B — Makefile (reproducible)

• Build Release: make build-release
• Package ZIP: make package (creates BusyMirror-<version>-macOS.zip + .sha256)
• Built app: build/DerivedData/Build/Products/Release/BusyMirror.app

See CHANGELOG.md for notable changes.

CLI (optional)

• Run from Terminal with --routes to mirror without the UI. Example:
  • BusyMirror.app/Contents/MacOS/BusyMirror --routes "1->2,3; 4->5" --write 1 --days-forward 7 --mode allow --exit
• Flags exist for privacy, all-day, merge gap, days window, overlap mode, and cleanup.
