Automatically delete a defined set of tags

As this is something quite specific for some user, it would be the best to solve it using a QML script. The following script will remove all frames except Artist, Album from Tag 2, you can easily adapt it for other frames or other tags:

import Kid3 1.0

Kid3Script {
  onRun: {
    function doWork() {
      if (app.selectionInfo.tag(Frame.Tag_2).tagFormat) {
        var frames = Object.keys(app.getAllFrames(tagv2))
        for (var i = 0, len = frames.length; i < len; ++i) {
          var type = frames[i]
          if (['Artist', 'Album'].indexOf(type) === -1) {
            app.setFrame(tagv2, type, '')
          }
        }
      }
      if (!app.nextFile()) {
        if (isStandalone()) {
          // Save the changes if the script is started stand-alone, not from Kid3.
          app.saveDirectory()
        }
        Qt.quit()
      } else {
        setTimeout(doWork, 1)
      }
    }

    app.firstFile()
    doWork()
  }
}

If you save it as "/home/matteo/RemoveFrames.qml", you can add it to the user actions in "Settings/User Actions" with Name="Remove Frames", Command="@qml /home/matteo/RemoveFrames.qml" and Output checked (to see any errors). You can afterwards invoke the script using the context menu of the file list.

Thanks so much, I'll try to make it work as i'm not an expert with scripts but i should manage
Thanks again!

I got it to work but I get this error message
file:///Users/matteo/Documents/RemoveFrames.qml:6: TypeError: Property 'tag' of object TaggedFileSelection(0x7ff18d04cf20, "TaggedFileSelection") is not a function

If you manage to help me with it would be great
thanks again

If you are not using the latest version of Kid3 (3.4.2), you have to replace app.selectionInfo.tag(Frame.Tag_2).tagFormat by app.selectionInfo.tagFormatV2

I made a mistake in the update, sorry.
Works perfectly, thanks a lot! This will save me a lot of time :)
Thanks again for your efforts in the app!
