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.

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

Option A — Xcode

Open BusyMirror.xcodeproj in Xcode.
Select the BusyMirror scheme → My Mac.
Product → Build.
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.

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.
