Question

SDK: Plugin dependent on application running

  • November 21, 2023

Is it possible for a plugin (or scripts within a plugin) to work only if a particular application is running on the user's system? This would be macOS-specific.

 

If not, I could probably use LrFileUtils.exists( path ) to determine if an application exists but this wouldn't tell me if the application is running, just if it exists. 

 

Any tips would be greatly appreciated.

    You could run the this command line using LrTasks.execute() to examine the list of running processes for the one you're interested in:

     

    ps xo command > temp-file

     

    I think you could also run an Applescript script that queries System Events for a process. But every time I turn to Applescript, there goes several hours of googling for all of its peculiarities.

    Thanks, @johnrellis - sort of related question, is it possible to have a plugin's menu items show only when certain conditions are met?

    Not in general. You can specify some conditions on selected photos (e.g. whether a photo is selected), as described in the SDK Programmer's Guide, but that's it.
