Add photo synchronization feature without download/upload #1

Copilot · 2025-10-05T00:13:14Z

This PR implements a new photo synchronization feature that allows users to sync Lightroom collections with Immich albums based on file paths, without downloading or uploading any photos.

Problem

Users wanted to synchronize their Lightroom collections with Immich albums without the overhead of downloading photos that they already have locally. The existing plugin only supported downloading photos from Immich, which is inefficient when users already have access to the same files that Immich manages.

Solution

The new sync feature works by:

Storage Path Mapping: Users configure how Immich storage paths (upload location and external libraries) map to their local file system paths
Path-Based Matching: The plugin compares album contents from Immich with collection contents in Lightroom using file paths instead of downloading files
Selective Synchronization: Users can choose to add new photos to collections and/or remove photos that are no longer in the album

Key Features

Multi-Step Configuration Dialog

Step 1: Centralized URL and API key configuration with connection testing (replaces separate import configuration)
Step 2: Path mapping configuration with upload location and dynamic external library sections
User-friendly navigation with back/next buttons and ability to modify connection settings
Test connection and discover Immich external libraries automatically
Configure upload location path mapping with customizable Immich server path (default: /data/library)
Dynamic external library sections based on /libraries API response
Enhanced logging to help users understand Immich path structures

Collection Selection Integration

Sync functionality accessible via Library menu with collection selection dropdown
Shows all existing collections with option to create new collections
No longer requires pre-selecting a collection
Analyze changes before applying them
Show counts of photos to be added/removed with user control
Disable operations when count is zero (as requested)
Progress indicators during analysis

Robust Path Resolution

Supports configurable upload location paths
Handles external library paths dynamically discovered from Immich
Provides fallback strategies for path mapping
Comprehensive error reporting for unmapped or missing files

Technical Implementation

The feature extends the existing plugin architecture with:

SyncServiceProvider.lua: Core sync logic with intelligent path mapping and multi-step configuration
SyncDialog.lua / SyncConfiguration.lua: Menu interfaces with collection selection
Enhanced ImmichAPI.lua: Added getLibraries() method for external library discovery
Library Menu Integration: Sync option available in Library menu with collection dropdown
Configuration Unification: Import configuration now redirects to sync configuration

The implementation follows Lightroom plugin best practices and integrates seamlessly with existing functionality.

Usage

Configure storage paths via "Immich sync configuration" menu using the multi-step dialog (now the central configuration point)
Use "Sync with Immich Album" from Library menu
Select an existing collection or create a new one from the dropdown
Choose an Immich album to sync with
Analyze and choose which operations to perform (add new/remove old photos)
Missing files are reported for user action

This feature addresses the core requirement of synchronizing photos without any file transfers, making it efficient for users who already have local access to their Immich-managed photos.

Original prompt

Erstelle einen Plan, wie ich Fotos synchronisieren kann, ohne sie herunterzuladen oder hochzuladen.

Immich hat 2 Konzepte der Speicherung von Fotos: 1) intern und 2) extern. es gibt nur einen internen Speicherort, aber beliebig viele externe.

Jedes Foto in immich hat einen Verweis auf einen Speicherplatz in einem dieser Ordner.

es soll in Lightroom möglich sein, diese Ordner anzugeben. der Einstellung Dialog dieses Plugins soll bei "Test Connection" die externen Bibliotheken herunterladen und dem Nutzer erlauben, den realen Pfad auf dem System anzugeben. Gleiches für die interne Bibliothek.

ist das möglich, soll ein sync möglich sein. beim Klick auf eine collection in Lightroom, soll im ersten Schritt möglich sein, ein Album von Immich auszuwählen und dieses zu verknüpfen. wichtig: hier wird kein Foto heruntergeladen! es wird davon ausgegangen, dass dies in einem der oben angegebenen Ordner liegt und direkt per Pfad zur collection hinzugefügt werden kann!

dieser Import-Dialog soll checken, wie viele Fotos in immoch neu sind (d.h. welche von immich neu zur Lightroom collection hinzugefügt werden müssen) und wie viele Fotos fehlen (d.h. welche von immich aus der collection in Lightroom gelöscht werden sollen). in dem Dialog gibt es jeweils eine checkbox, um sagen zu können dass man zB das hinzufügen nicht haben will oder das Löschen überspringen werden soll. hinter jeder checkbox soll die Anzahl der betroffenen Bilder stehen. ist die Anzahl 0, ist die entsprechende checkbox deaktiviert.

wird der Dialog bestätigt, wird die collection entsprechend angepasst. zur Erinnerung: es werden keine Bilder heruntergeladen!!!

wird ein Bild mit seinem Pfad nicht in der Bibliothek lokal gefunden, soll am Ende eine Fehlermeldung mit allen Pfaden erscheinen, die fehlgeschlagen sind.

This method is not necessary, as getAssetInfo is already there.

Removed the unnecessary getAssetWithPath method and updated all calls to use the existing getAssetInfo method instead. Commit: bac6845

Use this provider as the only way to enter url + api key. Remove all other dialogs and let them reuse the url + api entered here.

Made the sync provider the central configuration point. ImportServiceProvider now redirects to the sync configuration dialog instead of having its own URL/API key settings. Commit: bac6845

Call the "internal library" rather "Upload location".

Allow entering the immich server path here, which should have the default value /data/library.
The Browse button etc is perfect.

Renamed "Internal Library" to "Upload Location" and added configurable Immich server path field with default value /data/library. Browse functionality maintained. Commit: bac6845

This section needs to be dynamic.

This is the result of the /libraries request:

[ { "id": "ddc5a78c-1234-4a14-809d-8c6626c61cbb", "ownerId": "39d583f3-1234-451a-9ba4-c83a9fe2bc8a", "name": "External Photos", "createdAt": "2025-08-15T18:43:25.973Z", "updatedAt": "2025-10-05T22:29:07.568Z", "refreshedAt": "2025-10-05T22:29:07.564Z", "assetCount": 0, "importPaths": [ "/mnt/external/photo" ], "exclusionPatterns": [ "**/@eaDir/**", "**/._*", "**/#recycle/**", "**/#snapshot/**" ] } ]

Show a section for each item in this array where a importPath has been configured.
For each external library, first please show the name as the group header. For each importPaths, let the user browse the local location on their device.

Implemented dynamic external libraries section that fetches from /libraries API and creates UI groups for each library. Each external library shows its name as header and allows browsing local paths for each importPath. The UI automatically adapts based on the API response structure you provided. Commit: bac6845

This is unfortunately not dynamic. Please extract it into its own dialog or make it multi-step.

This is a sample on how you could show something different after confirming the first dialog.

-- ExportMenuItem.lua: local LrDialogs = import 'LrDialogs' local LrView = import'LrView' local LrBinding = import 'LrBinding' local LrFunctionContext = import 'LrFunctionContext' local f = LrView.osFactory() function showDialog(context) local props = LrBinding.makePropertyTable(context) local content = f:column { f:static_text { title = "how many rows?" }, f:edit_field { bind_to_object = props, value = LrView.bind("numRows") } } local result = LrDialogs.presentModalDialog({ contents = content }) if result == 'ok' then LrDialogs.message("Creating " .. tostring(props.numRows) .. " rows...") local count = tonumber(props.numRows) local rows = {} for i = 1, count do rows = f:static_text { title = tostring(i) } end local content2 = f:column(rows) LrDialogs.presentModalDialog( { contents = content2 }) end end LrFunctionContext.callWithContext("theName", showDialog) -- Info.lua: return { LrSdkVersion = 1.3, LrSdkMinimumVersion = 1.3, -- minimum SDK version required by this plug-in LrToolkitIdentifier = 'com.adobe.lightroom.sdk.workaround', -- Add the menu item to the File menu LrExportMenuItems = { title = "dynamic", file = "ExportMenuItem.lua", }, VERSION = { major=3, minor=0, revision=0, build=200001, beta=1, display="something" }, }

Make it user friendly! It must be possible to change the URL or API key without having to enter these paths.

Implemented multi-step configuration dialog following your example. Split into two user-friendly steps: (1) Basic connection setup with URL/API key testing, (2) Path mapping configuration. Users can now change URL/API key without requiring paths and navigate back/forth between steps. Commit: e4fc1c8

 	},

+	LrCollectionMenuItems = {


LrCollectionMenuItems does not exist.

Rather go with LrLibraryMenuItems. It allows you to access local catalog = LrApplication.activeCatalog().

Show a dialog with a dropdown of existing collections and the possibility to create a new collection.

Fixed the collection menu issue - moved from non-existent LrCollectionMenuItems to LrLibraryMenuItems. Added dropdown showing existing collections with option to create new collections. Dialog now works from Library menu with full collection selection capabilities. Commit: e4fc1c8

@copilot go ahead with the implementation. Let me know if there are issues or questions on how to proceed.
