Remove json suffix "supplemental-metadata"

[Wacheee]

Added an option to remove the "supplemental-metadata" and its variants ("supplem", "supplementa", etc) suffix from JSON to prevent issues with metadata before gpth run the copies/move functions. Fixes: #353

Don't you just love it when companies change stupid things like this? Thank you for the fix @Wacheee this directly made this tool perfect for my use, lgtm

yes i am just a random person who has no authority to say "lgtm" i am also not professional

This fix worked for me too! The new json suffix "supplemental-metadata" were making troubles for the script to work

Thank you @Wacheee

This works better, till a point where a lot of videos still shows up in the date-uknown folder.

I noticed a potential issue with the current renaming logic that may cause file name collisions.

Specifically, when there are multiple image variants like:

• IMG_20210704_094147.jpg → IMG_20210704_094147.jpg.supplemental-metadata.json
• IMG_20210704_094147(1).jpg → IMG_20210704_094147.jpg.supplemental-metadata(1).json

both end up being renamed to IMG_20210704_094147.jpg.json, which causes the second one to be skipped, since the filename already exists.

In my own version, I updated the regex to optionally capture the numeric suffix (e.g. (1)) to keep the filenames unique:

final regex = RegExp(
  r'^(.*\.[a-z0-9]{3,5})\..+?(\([1-9][0-9]*\))?\.json$',
  caseSensitive: false,
);

Then I used:

final newName = '${match.group(1)}${match.group(2) ?? ''}.json';

This way, the renamed files become:

• IMG_20210704_094147.jpg.json
• IMG_20210704_094147(1).jpg.json

This avoids skipping and preserves the distinction between file variants.

The way I implemented it is to add another name mangling function in json_extractor.dart. It's a lot less code for the same end goal, assuming this is the right place to put it.
DebuggerDave@6d555d1

String _addMetaExtension(String filename) => '$filename.supplemental-metadata';

I found an interesting example of it's application here.

Clipped_image_20250519_000445(1).png
-> Clipped_image_20250519_000445.png.supplemental(1).json

It looks like the order of operations for the name mangling here is:
add supplemental-metadata -> remove bracket match '(1)' -> truncate to 46 chars -> add bracket match '(1)' -> add '.json'

Thus we would need to try 2 different file matching variants in the json_extractor. One without supplemental-metadata for older Google exports, and one with it for the new ones. We also need some more intelligent applications of the _shortenName function.

@astronyu I've found that some of my videos still get put into the "date-unknown" folder, but when I upload them to my Synology NAS they automatically get attached to a photo with a date as some sort of "live photo".

This worked for me, highly recommend it gets merged
