Update the diff table of contents to use hierarchical views and edit distance renames

Authored by epriestley on Apr 28 2020, 7:23 PM.



Ref T13520. Generally, make the table of contents look and more like the paths panel:

  • Show a hierarchy, with compression for single-sibling children.
  • Use the same icons, instead of "M D" and "(img)" stuff.
  • Use EditDistanceMatrix to do a piece-by-piece diff of paths changes.
  • Show path changes within the path list.

I'm not entirely sold on this, but it was complicated to write and I've never heard the term "sunk cost fallacy". I think this is mostly a net improvement, but may need some adjustments and followup.

Test Plan

Viewed various changes in Differential and Diffusion, saw a more usable table of contents.
