    Is there a way to use it with git without having to change your global git config? I.e. `git diff | omnidiff` or something?You can do this with delta: `git diff | delta --side-by-side`

    cool to see fresh Rust software with copyleft license !I feel safer, as a user, enjoying the freedoms that the AGPL provides me. (No evil middleman will be able to give me non-free versions of this program.)

    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?Any interest in getting the setup upstreamed[1] so that users only need to `git config --global diff.tool omnidiff` to enable it by default? Disclosure: I created `git difftool` a long time ago, and am always happy when builtin support for useful tools are added to it. Feel free to reach out if you'd like help making that happen.[1] https://github.com/git/git/tree/master/mergetools

    Delta has a really nice way to show diffs with its diff-so-fancy mode, it's more similar to GitHub's UI where not only the line is colored up differently but there's a different shade of color to highlight the characters.There's a screenshot and video of it here that I wrote a while back: https://nickjanetakis.com/blog/awesome-git-diffs-with-delta-...In OmniDiff's readme and web version I didn't see a way to do that.In a different comment you mentioned OmniDiff is much better than Delta and you mentioned "About a third of diffs are significantly better.". Can you provide some examples of these? I've never seen Delta fail a diff.Also Delta has a package for Arch in its official repos. For folks who just want a "it works" experience, that's a pretty big win. With Delta the same package can be installed in the same way on Debian, Arch and macOS with Brew using standard package managers. With OmniDiff, there's 3 different ways to install it (manual deb package on Debian, manual package compile on Arch and brew install on a Mac). Just something to think about, as someone who has public dotfiles that work in those 3 environments, I'd skip OmniDiff based on this alone.

    Wow, I've often wished I had a tool like this. Thanks!Since most people do click-and-run most of the time (based on decades long research, n=1), I'll just add paste the link for more examples: https://ivankovic.github.io/omnidiff/showcase/content.html

    This looks really good. It does look like you put a ton of effort into it, I'll give it a try.I feel like the moved code cases would look great in https://github.com/andunieee/twain, I was looking into how I could slurp your code and make it work there (although for some reason I have the impression that I had already seen this repository in the past, I can't remember where).

    Really well done, I like this a lot. It produces much more minimal diffs than other tools I've tried.One feature I miss from difftastic is showing diffs side-by-side on wide terminals, and unified when narrow.

    How is it better or worse compared to https://github.com/dandavison/delta ?
  • smallnix
    Very cool! I'd love to see support for figma or Photoshop, perhaps it's already possible via export to an image format, but native would be cool.

    How does it compare with diffstatic?

    You have a good core idea here. You're pretty much killing your project in infancy with the AGPL+donation license model. Meanwhile, some other projects will take the core idea of "language aware differ" and release BSD, and one of those will win, including perhaps making it into git/future version controls.IMO, you should seek to make this a standard that wins, and hopefully other opportunities that come will be where you make commercial hay. My unsolicited 2c.

    I am sorry, I looked through the examples and I am not sure I prefer the output of omnidiff... Seeing how everyone else over here is instead overly enthusiastic makes me feel extremely dumb :D
