Behold! Dart edition!

[TheLastGimbus]

Hi @everyone!

Yes, I am alive. For a long time, to any bigger issue that showed up here, i responded "idk, code is 💩, will rewrite it some day"

So I did 🎉

Behold, Dart

GPTH, on new gpth_dart branch, is now written in Dart language - it allows way better organization than Python, and has beautiful tools for manipulating lists, async/await, etc - thanks to this, whole code is 160 lines less now (without test/), while doing things more stable, perdictable, and actually being documented

Missing stuff

Sadly, some functionalities are missing now:

• script does not write timestamps/geo data from jsons back to files - this may be sad in some cases (where people manually edited the location in app) - but i think it's better for the simplicity
• --skip-extras-harder was removed
• --divide-to-dates not implemented yet - but will be 👍

Stuff working better than ever

• finding duplicates/identifing albums is now stable (at least from my perspective because i finally know how it works)
  anyone interested can take a look: https://github.com/TheLastGimbus/GooglePhotosTakeoutHelper/blob/gpth_dart/lib/duplicate.dart
  • Inconsistency of "duplicate removal" + missing transperancy #110 i'm looking at you
  • sadly, finding albums is still purely theoretical, because we don't know what to do about it
• testing - lib/ is ~77% covered 💯
• performance - didn't test yet but expect a big difference 💯
  • you also now have clear choice between coping files - which leaves input folder completely untouched (in contrast to python version 🙄), and moving them, which should be very good performance

Fixed issues

• json names being trimed to 51 chars prevented script from finding jsons - JSON naming too long? #8
  I marked this as "too hard to resolve" in my head, but now in Dart it's fixed, meaning finding correct json should be 99% success. And if not...
• nicely standardized date extraction - @tkuenzle in Make date extraction more modular #112 suggested that date extraction should be cleaner and modularized - python script was to shitty for that, but now take a look at

  GooglePhotosTakeoutHelper/bin/gpth.dart

  Lines 68 to 72 in 3695208

  	final dateExtractors = <DateTimeExtractor>[
  	jsonExtractor,
  	exifExtractor,
  	if (args['guess-from-name']) guessExtractor,
  	];

  - nice and clean!
  • added "guess from name" based on @hheimbuerger work <3
• HEIC Support for EXIF data #44 🎉 since https://pub.dev/packages/exif supports it
• overall consistency and sureness - if new issue raises, it should be actually possible to fix instead of crying about it

I need you ☝️

I would be very happy if you guys could help and test how new version works for you etc:

• @MrModest - does Don't reset original created time for un-guessed files. #128 still bother you with Dart?
• @jacobastern do you get more success in guessing dates, which would resolve Some MVIMG files are not organized correctly with the --divide-to-dates flag #105 ?
• @tkuenzle how do you like the modularity?
• @giantpune i think i could implement Strategies for timestamping more photos and videos. #102 now - what do you think?

Binaries are in releases for you ❤️
