Unique filenames for singletons

[jaimeMF]

I know that for albums you can use %aunique for generating unique filenames for different albums. Is there something equivalent for singletons? I have a couple of standalone tracks from the same artist and with the same title, like for example 1 and 2, and beet move always tries to rename them:

> beet move -p ugo
Moving 1 item (1 already in place).

Very interesting! We don't currently have an analog to %aunique, which is a surprisingly complicated set of functionality, for singletons instead of albums. It would certainly be interesting to consider!

Barring that, one option would be to think of some distinguishing field you'd like to use in your filenames for these tracks. Then you could manually mark them as "ambiguous," using something like beet modify ambig=1 Fantasy on Veni Creator Spiritus, Op 7. Then, in the paths: section of your config, you could add an extra path template just for this kind of track:

paths:
    ambig:1: Non-Album/$artist/$title - $catalognum

…or whatever, replacing $catalognum with the disambiguating field you want to use.

Thanks, that's an option.

Since I would prefer to have something that works automatically I will try to implement a %sunique function.

Would it make more sense to have aunique work on arbitrary inputs (albums and singletons)?

#4438 ultimately shared a lot of code with %aunique, but it remains a separate path function.
