I managed to display a table with rows and column using the LrDialogs.presentModalDialog. All the values from the orginal table I converted to a flat property table.   propertyTable = LrBinding.makePropertyTable(context)     Before adding the new row I display the table. This works fine Ofcourse variable "c" contains all groups, rows and columns.     dialogValue = LrDialogs.presentModalDialog( { title = "My table", contents = c, }     Having my original table and a flattened projection of it as property table, below the table rows I added a button. The button calls a function which performs the steps below: Adding a row to my original table Updating the property table with these new values Added a row to the contents in variable "c" After these steps I tried to stop and show the dialog again, however that doesn't work.   LrDialogs.stopModalWithResult(dialogValue) dialogValue = LrDialogs.presentModalDialog( { title = LOC "$$$/LightroomStatistics/Dialogs/Translations=Translations", contents = c, } )   Question How can I redraw / redisplay  the modal form. ...

Being somewhere in the Library module, I want a certain image to be show / active in the Develop module.   The code below works as long as the image to be shown is in the grid. However, when the image is not in the active grid, then the Develop module reports "No photo selected". Even though if I go back to the grid and select "All photographs" in the left panel, the image is the selected image with the white border. The issue is that upon the start of this plug-in I want to show a specific image in the Develop module, however I have no glue which folder or collection is active at that moment.   local function showInDevelopModule(photo) catalog:setSelectedPhotos(photo, {}) local moduleName = LrApplicationView.getCurrentModuleName() if (moduleName ~= "develop") then LrApplicationView.switchToModule("develop") end end LrFunctionContext.postAsyncTaskWithContext("test", function(context) local message = nil LrDialogs.attachErrorDialogToFunctionContext(context) local photo = catalog:findPhotoByUuid("0AFA8451-6DDD-4CF6-B537-DB1E9FB53A88") showInDevelopModule(photo) end)   ...

While importing photos from disk I'm struggling to stack these photos with existing photos in the Lightroom catalog.   My use case: In my Lightroom catalog I have 2 images On my disk I have 2 other images, noy yet loaded into Lightroom. Their file name makes it clear which image on disk belongs to which image in the database I'm using: catalog:addPhoto( filePath, photo, 'above') What works well? The images are loaded into Lightroom. What works not? They are not stacked. Question: what am I missing?   Steps to reproduce See the attached images Import the two photos without "_nbg" into Lightroom Put the other two, without "_nbg" in the file name, into some directory. Change in my sample code below my directory name with the directory name you used above.   I downloaded the images from Unsplash.com   local LrApplication = import "LrApplication" local LrDialogs = import "LrDialogs" local LrFileUtils = import "LrFileUtils" local LrFunctionContext = import "LrFunctionContext" local LrPathUtils = import "LrPathUtils" local logFilename = "StackPhotos" local myLogger = import 'LrLogger'( logFilename ) myLogger:enable( "logfile" ) local catalog = LrApplication.activeCatalog() local function findByName(filename) local foundPhoto = catalog:findPhotos { searchDesc = { criteria = "filename", operation = "all", value = LrPathUtils.replaceExtension(filename, "jpg"), value2 = "", } } return foundPhoto end local function main() myLogger:info("Main: start") --Import both photos WITH background in Lightroom: everyday_matters-closedEyes.jpg and Reinaldo Kevin.jpg --Put in the directory of your chosing the 2 images without background: everyday_matters-closedEyes_nbg.png and Reinaldo Kevin_nbg.png -- BTW _nbg stands for no background local destinationPath = LrPathUtils.standardizePath("D:\\Temp\\Lightroom Burned Exports\\output") myLogger:info("destinationPath", destinationPath) -- Prepare database for adding photos catalog:withWriteAccessDo ("Stack", function () -- Loop the folder with the image with no background for filePath in LrFileUtils.directoryEntries( destinationPath ) do -- Determine the file name of the original photo by removing the "_nbg" local leafName = LrPathUtils.leafName(filePath:gsub("_nbg", "")) local photo = findByName(leafName)[1] if (photo) then myLogger:info("Image found", leafName, photo, photo:getFormattedMetadata("fileName")) catalog:addPhoto( filePath, photo, 'above') else myLogger:info("Image NOT found", leafName) end end end) LrDialogs.message("Stacking photos", "Finished stacking photos") end LrFunctionContext.postAsyncTaskWithContext ("Stack photos", function( context ) LrDialogs.attachErrorDialogToFunctionContext( context ) main() end) The log file 05/20/2024 16:18:37 INFO Main: start 05/20/2024 16:18:37 INFO destinationPath D:\Temp\Lightroom Burned Exports\output 05/20/2024 16:18:37 INFO Image found everyday_matters.png LrPhoto( id "126" ) everyday_matters.jpg 05/20/2024 16:18:39 INFO Image found Reinaldo Kevin.png LrPhoto( id "121" ) Reinaldo Kevin.jpg   ...

We need to be able to identify whether a specific creative profile has been imported into LrC.   I know that we can see presets, but are we able to see creative profiles in the same way? Does the SDK provide this option?   The only option I can think of is looping all files below the CameraRaw directory looking for a <profile name>.xmp file. ... View more

When I try to load a different module from a lua script in de script directory, I get an error. I created a module from the crop-corners.lua script which John Ellis described on this forum. That module I would like to insert = require   I tried all kind of variations to what works normally inside a plug-in, but with no luck. local myModule = require 'myModule'   To be clear, the script is NOT a plug-in, but a lua file in the script directory. From this script I want to load a different module (lua script) in the same script directory. ... View more

By default my LrDialogs.presentModalDialog actionVerb is set to Done. However, when a certain value is entered in the taskDescription edit_field, it should change to a different value.   Question: is it possible to change the actionVerb of a presentModalDialog to a different text based on the user input? I tried the following with an addObserver and the static_field is changed correctly when the user enters "Change", however the button text remains the same.   local LrBinding = import "LrBinding" local LrDialogs = import "LrDialogs" local LrFunctionContext = import "LrFunctionContext" local LrView = import "LrView" local bind = LrView.bind LrFunctionContext.callWithContext ("test", function (context) local f = LrView.osFactory () local p = LrBinding.makePropertyTable (context) p.taskDescription = "" p.buttonTitle = "Ok" p:addObserver( 'taskDescription', function( p, key, newValue ) if (newValue == "Change") then p.buttonTitle = "New name" end end ) local res = LrDialogs.presentModalDialog { title = "Test", contents = f:row { bind_to_object = p, f:edit_field {alignment = 'left', place_horizontal = 0, width_in_chars = 20, immediate = true, value = bind "taskDescription" }, f:static_text {alignment = 'left', place_horizontal = 0, width_in_chars = 20, title = bind "buttonTitle" }, actionBinding = { enabled = LrBinding.keyIsNot ("taskDescription", "", p) }, actionVerb = bind "buttonTitle" } } end)   ...

What I want is to have the dialog Ok button only be enabled when a edit_field is not empty.   In the post https://community.adobe.com/t5/lightroom-classic-discussions/modale-validation/m-p/9351740 John Ellis gives the following example which I extended by one edit_field. Setting the check on the popup_menu works, setting it on the popup_menu works not.   2 questions: What am I missing that this doesn't work for the edit_field What is the most easy way to disable the Ok button if an edit_field is empty.

I created a plug-in which might take some time to finish dependant upon the number of photos selected. Question: how I can prevent that the plug-in is started anew while it is already running?   Currently I update the LRPrefs at the start and again when the plugin finishes. However I don't like this solution, because sometimes, due to an error, the plugin quits and then the 2nd LrPrefs call is never made and the plugin prevents to start. Ofcourse that can be reset, but I would like to know if there is a better way that the plugin itself can detect that it is already running. ... View more

In the plugin manager I want to show information retrieved via an API. I get the error "We can only wait from within a task".
