How to know if one folder is proceeded or not?

[bebound]

I'm trying to organize my existing library with beets. First, use -q for automatic import. Then, in the second pass, interactively import skipped files with --from-logfile. However, there are too many folders to do this all at once. Next time, it still tries to import processed folders and I have to manually edit the log file.

I prefer writing my own script to call Beets to import each folder individually. However, I'm unsure if a folder has been processed or not.

1. Use log?
   Currently, the log only records skip or duplicate-replace, without indicating which folders were successfully processed.

import started Tue Dec 17 03:14:11 2024 (It seems this folder is proceeded, but I don't know the name)
skip /Downloads/xxxxxx
duplicate-replace /Downloads/xxxxxx

Can Beets write logs like this: apply /Downloads/xxxxxx?

2. Is it possible to know the result of the last executed Beets command?
3. Read state.pickle? It seems to store information about processed folders.

By knowing this, I could write a dummy file in the processed folder and then skip that folder next time.

Any suggestion is appreciated.

PS: I want beets to monitor a folder and automatically import new albums, which is possible if I know if one folder is processed or not.
