MixesDB:Tests/Tracklist Merger

Still in Beta… Requires a userscript – check Discord channel #trackidnet

Updates

2025.08.24.4

• The Candidate diff is more or less fixed. It goes word by word so returning the result is slower now. Unused cues, and complete words like artists and versions are highlighted.
  Still it highlights the whole track when there a minimal changes within a word like a typo. Can't get the AI to fix this atm.

2025.08.23

• TID now removes country codes like "Foo (BE)" properly in all kinds of variations
• The 3 columns are no more 1/3 width each, but spread by actual text row width per column (usually the Original columns need less width). This avoids line breaks when there is actually enough space.
  Between the columns is an invisible divider to resize columns (indicated by drag cursor icon).
• The diff section updates live as you type in any textarea of the Inputs section.

Bugs:

• The Candidate diff highlights the whole track instead of only the non merged characters / words.

Older updates

2025.08.21.3

• Artist - Track is matched more flexible now. Durations are also added for these cases:
  • Artist collab order: Artist 1 - Trackname matches Artist 2 & Artist 1 - Trackname (and various combinations) (dur is added, Artist 1 - Trackname from Original unchanged)
  • Candidate has a version (dur added, text difference highlighted). Pointless versions like Radio Edit are removed in TrackId.net userscript directly (before passed to Merger).
  • Labels are ensured to be ignored for matching (dur is added, missing label added, label text difference highlighted)
• Textareas and pre tags have the same max height now

2025.04.25.1

• The merge function was improved to respect gaps in Original.
• New tracks from the candidate are not merged when the candidate has new cues that don't exist in the Original.
• The diff function remains imperfect for Candidate:
  • Only the words that are different should be highlighted.

Examples

All candidates from TID atm.

Example	Merged result	Candidate diff
Full tracklist without dur	Works fine	[39] should have only Anemone highlighted
2-digit dur matching 3 digit dur	Works fine and [039] Dold - Untitled 29 [Unterwegs] is not highlighted green as new track
Gap tl to full tl w/o dur	Works fine Cue and labels are added Aly-Us - Follow Me (Bok's Dub) remains and is not using (Full Intention Club Mix) from the candidate (but highlighted in diff for you to check)	Only text differences are highlighted red
New track in Candidate	[23] Gresil - Mutation Blooding II is merged as new track (new cue)
Multiple new tracks added	All new inserted tracks are highlighted
Large gaps	Works fine	[043] Ø [Phase] - Perplexed (Rødhåd's Extended Mix) [Token] is not added (but highlighted) because there's a [042] track and we have a minimum gap of 3 minutes for assuming a new track
Artist aka Alias - Trackname in Original	Polyvinyl - Endgame In Mind (Chlär Remix) [Suara] is not inserted again as [49]	[49] Polyvinyl - Endgame In Mind (Chlär Remix) [Suara] is not highlighted red as text difference
Cue variations (XX:XX vs XX)	Cue variations XX:XX and XX etc are catched
;Chapters and formatted Special:	Chapters are preserved Formatting of '''Special:''' destroyed by the Tracklist Editor API (bug)	Part 2 tracks should not be highlighted red
Original = Candidate	No changes as expected. And adds + highlights new tracks e.g. by adding a trackname for [39] in Candidate.	No Candidate diff (identical)
Candidate tracks with missing brackets around versions are found as new tracks (042, 113)
+ Acapella	The Acapella should not be [04]

I try to run them all again with new updates, but some may fail, esp. the diff may behave differently from version to version.

Diff rules

Highlighting rules

• Don't highlight entire rows or trackText, when only a word or a character is different. For each matched and unmatched track go word by word, then single character per word.
• Go track by track as you did on the matching, do not compare complete texts.
• Don't use a similarity threshold for finding text differences.
• Treat cue, trackText and label as own groups when comparing.
• Never highlight blanks at the beginning or end of a highlight string.
• Never highlight prefix "# ".

Inputs
Original Copy from mix page Do not change given dur, track or label. Do not remove any tracks. Only add new information.	Merged Copy-ready result. You can change the tracklist here and the diff will update.	Candiate Paste e.g. a TID tracklist Take each track with text (not ?). When found in the Original, add dur and label (if exists) to the matched track in Original. When the next Candidate track after the match is ?, then use the dur and add it to the next track after the matched track in Original. Match a track also when Original has no version and Candidate has these version variants (ignored): Extended|Main|Original|Remaster Mix|Edit|Version etc
