I am loving getting organised with my tagging and am writing scripts to automate significant bits of my tagging workflow but I am missing some fundamental understanding about YATE scripting and could do with some help. Please don’t go to the trouble of creating this action for me but some guidance would help me enormously to understand the challenges I need to overcome and the way to script YATE in the future.

As part of my workflow I work through all files that I am importing and check that albums have correct disc information. I don’t use three figure track numbers (e.g. 102 to indicate track 2 of disk 1) but rather make sure that disc field is correct and since I have started to play with YATE I now need to check the "disc count” field to make sure that “e.g. 1 of 2” is correct. Furthermore, if there is only one disc in an album I remove anything in disc or disc count. So, thinking through what I need to achieve:

The script needs to:

1. Detect that multiple albums are selected and deal with them in one execution (I will use the same inconsistency checking that you wrote into the move/rename action that you created a few weeks back)
2. Check for any existing value of field: disc
3. Check for any existing value of field: disc count
4. Check for any appended disk number on album name (use the existing “set disc numbers from Album Name 2” action)
5. Check for any existing parent folder that might indicate disc (e.g. Numbers or disk/disc)
6. Check for three or more figure track numbers (use an alert to ask user whether it's OK to process – it might just be that there are over 100 tracks in the album)

So, at this point I should have a pretty good idea of whether a track is part of a single disc album or a multi-disc album and I can process it depending upon what variables are set:

1. If disc count is 1 and disc is 1 then remove all disc field values and skip everything else
2. If the album name or parent folder values are !=“” then assign values as appropriate
3. If the track has three digits then see if we can assign values as appropriate
4. If disc is empty but disc count is > 1 then see if we can get a value from album or parent folder values

I assume that I should run the script in grouped so that it will work through processing each file individually – sounds like the logical way to do it! But how do I make sure that YATE processes the whole album in the same way if we are only dealing with files. Or am I just complicating my thinking unnecessarily because the script will just work through each file processing it according to the rules and will maintain the albums that are already defined?

Specific questions:
1. The Disc of Calculation appears to populate the “disc of” field. There isn’t a ‘disc of’ field in the field list, so is this actually the "disc count" field?

I’ve had a go at starting this and I’ll carry on later but any feedback or pointers would be appreciated.
Cheers,
Crom

This is helpful, thank you. I read that article this afternoon, it was really useful.

Having done some more reading I think my basic approach is going to be:

1) Create a list per album and then loop through the list finding out what the data should be changed to on a per album basis and then processing each file within each album. That way I'll be able to process multiple albums in one run.

I've spent some time on this, this evening - basically creating a list of the albums and cobbling together some existing script from elsewhere on this site to check for disk details in the album title or the folder name. I'd appreciate any feedback on the general approach or specifics 😉

Also, is there a way in the editor to just delete functions? Backspace doesn't do anything and right mouse is long-winded.

Here's the code so far (such as it is!)
