Hi @disrupted, thanks for this. Is your request satisfied by using the --stat argument to git diff/show/log etc? That gives output like this with delta:

@dandavison this definitely goes in the right direction and I didn't know about it, so thanks for pointing it out.

I was thinking something more like this, where it would show the number of changes (additions/deletions) in the header for each file.

Most of the time I use delta with fzf (inside of forgit) so it would be really cool to show this information. Here's a small mockup of what I mean:

Hi @disrupted, I agree that could be nice. One concern however is that delta would have to process an entire file before starting to emit any of the output for that file, in order for it to be able to compute the diff summary. At the moment delta's processing is more stream-oriented than that, and it would raise the possibility of poor performance in the case of large files.

I like that idea, too !

Maybe the --shortstat option comes close to what @disrupted is imagining. It can be used with git diff -p, git show -p and git log -p.

As with --stat, git would do the calculation (and git is pretty efficient in that).

There are some caveats though :

1. When using with git diff or git show, you need to also apply the -p/--patch flag; otherwise only the shortstat will be outputted.
2. It will be a summary of changes in all files affected by the according commit. (There's the --numstat option, but that will output all statistics as a header, followed by all the diffs, and it would probably need to be parsed and reformatted.) I'm not aware of any way to have shortstats for each individual file inline, but maybe that's also possible somehow ? After all, git is a Jack of all trades in many regards... 😆
