SDK Naming History Step

[cwurzbach]

I am working on a Lightroom Classic plugin. Does anyone know if there is a way to set the history step name on the right-hand side of the history panel? See the screenshot.

I haven't found a way for plugins to control any aspect of history steps.

I know you can control the name of the history step (the name on the left-hand side of my screenshot) but I didn't know if there was a way to control the text on the right-hand side. Thanks again for your insight on this @johnrellis, it's much appreciated.

Do you know how to set the name of the history step?  With all my plugins, the "actionName" parameter supplied to catalog:withWriteAccessDo() sets the name in the Edit > Undo menu, but the history step always appears as "Camera Raw Settings":

I know how to set it for photo:applyDevelopSettings, which is what I am using. The history step can be named via photo:applyDevelopSettings( settings, optHistoryName [name history step here], optFlattenAutoNow ).

"The history step can be named via photo:applyDevelopSettings( settings, optHistoryName [name history step here], optFlattenAutoNow )"

Thanks much, I forgot that was documented in SDK 11.2.

@johnrellis Glad to help!

I'm reading through the SDK documentation and it indicates you can provide a name for the "undo/redo name" for LrTasks.startAsyncTask via LrTasks.startAsyncTask( func, optName [name goes here] ) but I can't seem to make it work for some reason.

Here is an example code:

LrTasks.startAsyncTask( function()
... task here ...
end)

I am not sure where or how to insert the optName. The following code doesn't work:

LrTasks.startAsyncTask( function(), "name",
... task here ...
end)

Any guidance? Your initial reply made me realize that many of my "Undo/Redo Names" are not defined so I am trying to set the names now. Otherwise, I get "Undo/Redo Names" like this:

The names of Undo steps are provided via the first argument to catalog:withWriteAccessDo(), e.g. 

catalog:withWriteAccessDo ("My Crop", function ()
    photo:applyDevelopSettings {...}
    end)

The "optName" passed as the second argument to LrTasks.startAsyncTask (fun, optName) is "for debugging only".  I assume that name gets attached to the task and will appear in the debugging facility Adobe uses for its Lua framework.  I've never seen that name appear anywhere in any value returned by the SDK nor in the Lua debugging hooks my Debugging Toolkit uses.

Thus, I never pass a name, since it has no apparent use to mere mortals.

This suggests you're passing an untranslated ZString to catalog:withWriteAccessDo():

catalog:withWriteAccessDo (
    "$$$/AgLibrary/CameraRawView/Ops/CropAspect=Set Crop Aspect Ratio",
    function () ... end)

rather than translating it with LrTranslation.LOC:

catalog:withWriteAccessDo (
    LOC ("$$$/AgLibrary/CameraRawView/Ops/CropAspect=Set Crop Aspect Ratio"),
    function () ... end)

@johnrellis thanks for the clarification on this. Good to know that the optName is for debugging only.
