How does it compare to Difftastic[1]? Both built on top of TreeSitter and solve similar problems.
Difftastic only diffs code, which is only 2/3 of all diffs.
When only measured on stuff difftastic supports:
Difftastic is perfect on 64% of diffs and near-perfect on 17% more.
Omnidiff is perfect on 90% of diffs and near-perfect on 5% more.
Speed is
p50 - 35ms difftastic vs 4ms OmniDiff p99 - 637ms vs 420ms
Difftastic is MIT vs AGPL.
Care to elaborate? What does Omnidiff offer for non-code files?
Note that you do need a terminal with image support, like kitty, alacritty.
If you do not have image support, it does its best with image2ascii, but it is obviously severely limited.

I did not find examples in the repo or any way to test what "perfect" or "near perfect" in those cases mean. On the playground you compare against unix diff only. Based on my quick comparisons with difft, I do not see much difference. Could you add a link to comparisons or show how it differs and what are those numbers based on??? I'm not dismissive, just looking for a proof or showcase.
Fair warning: the true comparison is fairly complex and doesn’t really lend itself to “quick comparison”.
Also, the research is NOT complete.
