What?

Hello everyone, you may know me from films such as… Kidding. But hello nonetheless, today I’m releasing the culmination of all of my recent sleepless nights.

This simple script scans the location of your Navidrome music collection, pulls the embedded rating and then adds that rating to your Navidrome account

Code

v 0.3: Not only was the last version hideous, it was inconsistent. Stuff that worked in single directory mode never worked in full mode. Also removed some print statements, cleaned up some others.

Usage

Copy the code block, create a Python script in your chosen directory and then run it.

Thanks

This truly would not be possible without the Fediverse community, especially the Lemmy community. So thank you everyone but especially

@Deebster@programming.dev @ggwithgg@feddit.nl @jnovinger@programming.dev @ishanpage@programming.dev @rglullis@communick.news @oscar@programming.dev @TootSweet@lemmy.world @sabret00the@mas.to @amcewen@mastodon.me.uk @oblomov@sociale.network @mdylanbell@fosstodon.org @mborous@mastodon.social @cohomologyisFUN@mastodon.sdf.org @eichin@mastodon.mit.edu @mdione@en.osm.town

For some of you what you did seemed so small, but it was massive to me and I’m incredibly grateful for your kindness.

The Lore

One day, one man decided that enough was enough, it was time to move to the modern age, but to get there he needed his music collection. However it wasn’t enough to just have the music, he needed the ratings too. First world problems, I know! So with nothing but hope, he said out in search of the ring! I mean the script! He couldn’t find the script, but Deebster offered to help and so the two of them embarked on a journey whereby I kept pasting stuff to Desbster and he was like “no” but under his guidance, my script born from the embers of Bard, started taking shape. Now, for me with zero Python experience, you can imagine that the guidance I required was a lot, but Deebster earned his Scout badge in guidance. And as I got closer and closer, I kept cutting my sleep short so that I could spend some extra time trying to figure it out. Also huge thanks to Minz from the Navidrome discord as they came in clutch with some API advice. Anyway, I got a working script and I’m paying it forward by sharing it. Thank you all again.

Anything Else

If you can see how I should improve this, please let me know. Thank you all again.
