I have been researching what the ultimate diff tool would look like, based on actual diffs in open source repositories. OmniDiff can diff: code (25 languages), config, images, PDFs, archives, cursors, fonts... It's fast. It can diff C++ files of tens of thousands of lines in under 100ms, on a 2023 ThinkPad T14s. It's open source. AGPLv3. It's based on real diffs. I looked at the 7400 repositories that are listed in Gentoo packages, sampled 2000 diffs and solved them manually to get a good…

From the discussion
A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
It would be nice if you checked out lazygit and consider adding support to it's recently added OSC1717, adding supporting for staging in the main diff view directly: https://github.com/stefanhaller/diff-line-metadata-spec Also it would be nice to have a more thorough and comprehensive comparison against difftastic,…
Nicely done OP. Does it do 3-way diffs for merges as well? The instructions only mention the two-way `git difftool` configuration so maybe that'll be a future feature?
