CLI: Library Sync Setup Commands

Overview

After pairing two devices, use these commands to set up library synchronization between them.

Prerequisites

Devices must be paired - Use sd network pair generate and sd network pair join first
At least one library exists - Use sd library list to see available libraries
Networking must be running - Check with sd network status
Know the device IDs - Use sd network devices to list paired devices

Commands

0. List Paired Devices (Get Device IDs)

First, you need to know the device ID of the paired device.

sd network devices

Options:

--connected - Show only currently connected devices

Example:

$ sd network devices

2. Setup Library Sync

Configure library sync between local and remote devices.

sd library sync-setup setup \
  --local-library <LOCAL_LIBRARY_ID> \
  --remote-device <REMOTE_DEVICE_ID> \
  [--remote-library <REMOTE_LIBRARY_ID>] \
  [--action <ACTION>] \
  [--leader <LEADER>] \
  [--local-device <LOCAL_DEVICE_ID>]

Required Arguments:

--local-library - UUID of your local library
--remote-device - UUID of the paired device

Optional Arguments:

--remote-library - UUID of the remote library to sync with (optional for register-only)
--action - Sync action type (default: register-only)
- register-only - Just register devices (Phase 1)
- merge-into-local - Future (Phase 3)
- merge-into-remote - Future (Phase 3)
- create-shared - Future (Phase 3)
--leader - Which device is the sync leader (default: local)
- local - This device is the leader
- remote - Remote device is the leader
--local-device - Override auto-detected local device ID

Example:

$ sd library sync-setup setup \
  --local-library 3f8cb26f-de79-4d87-88dd-01be5f024041 \
  --remote-device 550e8400-e29b-41d4-a716-446655440000 \
  --remote-library 7a9c2d1e-5f84-4b23-a567-1234567890ab \
  --action register-only \
  --leader local

✓ Library sync setup successful
  Local library: 3f8cb26f-de79-4d87-88dd-01be5f024041
  Remote library: 7a9c2d1e-5f84-4b23-a567-1234567890ab
  Devices successfully registered for library access

  Devices successfully registered for library access

# 8. Verify devices are registered
$ sd library info
# You should see the remote device in the devices list

Device B (iOS)

# 1. Enter pairing code from Device A in the app

# 2. After pairing completes, discover Device A's libraries
# (Use iOS UI or similar CLI commands when running on device)

# 3. Select libraries and set up sync
# (Use iOS UI for library selection)

Output Formats

All commands support --output flag:

# Human-readable (default)
$ sd library sync-setup discover <DEVICE_ID>

# JSON output
$ sd library sync-setup discover <DEVICE_ID> --output json

# YAML output
$ sd library sync-setup discover <DEVICE_ID> --output yaml

Common Use Cases

Scenario 1: Simple Two-Device Setup

You have a desktop and a phone, both with “My Library” auto-created.

# On Desktop
sd pair generate
# Share code with phone

# After phone joins:
sd library sync-setup discover <PHONE_DEVICE_ID>
sd library sync-setup setup \
  --local-library <DESKTOP_LIBRARY_ID> \
  --remote-device <PHONE_DEVICE_ID> \
  --remote-library <PHONE_LIBRARY_ID>

Scenario 2: Multiple Libraries

You want to choose which libraries to sync.

# Discover what libraries the remote device has
sd library sync-setup discover <REMOTE_DEVICE_ID>

# Set up sync for specific library pair
sd library sync-setup setup \
  --local-library <PHOTOS_LIBRARY_ID> \
  --remote-device <REMOTE_DEVICE_ID> \
  --remote-library <THEIR_PHOTOS_LIBRARY_ID>

# Optionally set up another pair
sd library sync-setup setup \
  --local-library <WORK_LIBRARY_ID> \
  --remote-device <REMOTE_DEVICE_ID> \
  --remote-library <THEIR_WORK_LIBRARY_ID>

Scenario 3: One-Way Registration

sd library sync-setup setup \
  --local-library <MY_LIBRARY_ID> \
  --remote-device <THEIR_DEVICE_ID> \
  --action register-only
# No --remote-library specified

Troubleshooting

”Device not paired"

Error: Device must be paired before setting up library sync

Solution:
1. Check pairing status: sd pair status
2. Pair devices if needed: sd pair generate / sd pair join
3. Retry sync setup after pairing completes

"Device offline"

Device: Bob's MacBook (550e8400-e29b-41d4-a716-446655440000)
Online: false

No libraries found on remote device

Solution:
1. Ensure remote device daemon is running
2. Check network connectivity
3. Verify devices can discover each other (mDNS)
4. Retry when device comes online

"Library not found"

Error: Library not found: <UUID>

Solution:
1. List local libraries: sd library list
2. Verify library ID is correct
3. Create library if needed: sd library create <NAME>

"Context not available”

Error: Context not available for library operations

Solution:
1. Restart the daemon: sd restart
2. Wait for initialization to complete
3. Check logs for networking initialization errors

Integration with Other Commands

List Paired Devices

# See all paired devices with details
$ sd network devices

Paired Devices (2 total, 1 connected):
  Name: Bob's MacBook
  ID: 550e8400-e29b-41d4-a716-446655440000
  Status: Connected

# See only connected devices
$ sd network devices --connected

# Check network status summary
$ sd network status
Networking: running
Paired: 2 | Connected: 1

Verify Registration

After setup, the remote device should appear in your library’s device list:

# Get library info (when UI supports it)
$ sd library info
# Device list will include the remote device

Advanced Usage

Custom Device ID

If you need to override the auto-detected local device ID:

sd library sync-setup setup \
  --local-library <LIBRARY_ID> \
  --remote-device <REMOTE_DEVICE_ID> \
  --local-device <CUSTOM_LOCAL_DEVICE_ID> \
  --leader local

Specify Remote as Leader

If the remote device should be the sync leader:

sd library sync-setup setup \
  --local-library <LIBRARY_ID> \
  --remote-device <REMOTE_DEVICE_ID> \
  --remote-library <REMOTE_LIBRARY_ID> \
  --leader remote

Future Commands (Phase 3)

When full sync is implemented, additional actions will be available:

# Merge remote library into local
sd library sync-setup setup \
  --local-library <LOCAL_ID> \
  --remote-device <DEVICE_ID> \
  --remote-library <REMOTE_ID> \
  --action merge-into-local \
  --leader local

# Merge local library into remote
sd library sync-setup setup \
  --local-library <LOCAL_ID> \
  --remote-device <DEVICE_ID> \
  --remote-library <REMOTE_ID> \
  --action merge-into-remote \
  --leader remote

# Create new shared library
sd library sync-setup setup \
  --remote-device <DEVICE_ID> \
  --action create-shared \
  --leader local
