alt Hacker NewsNicely 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.
At the moment the algorithm for code diffing is a particularly efficient implementation of APTED which is a tree diffing algorithm that doesn’t natively construct anything useful for a three way diff. I have a notebook with a bunch of failed attempts at a good algorithm for a three way merge, but so far nothing particularly impressive.
It’s a long term goal to solve, but it’s the hardest one.
I’ll definitely reach out to you to upstream. Thank you for the kind offer!
