Iniline refined git diff with live update (video demo included)

I often compare my files to the latest version committed in git and I thought it could be interesting to see these changes inline in the buffer, refined to character level, so I created this package as a proof of concept. I'm putting it here in case someone finds it interesting and wants to productify it (more testing, polishing, melpa), because I don't have the time to finish it. Video demo of how it works: https://i.imgur.com/I7ITkoE.gif Code: https://gist.github.com/codecoll/84245ad37efd947a4d8e3fd494a00091

That looks neat. Could you `M-x report-emacs-bug` as a feature suggestion, with your code?

This is better than diff-hl-mode. MELPA?

Looks cool, but has too many problems for now.

Function `my-inline-diff` bracket not pair. Didn't find incf function, so I replace it with cl-incf. Revert not work:` wrong type argument overlayp, nil ` ​ Emacs29 on macOS

Yep, there are still some bugs, but it's unlikely I'll have the time to work on them in the near future. I thnk the concept is promising, though, that's why I posted the code, in case somebody wants to finish it.

>Function my-inline-diff bracket not pair. Fixed. It's a copy paste error. I should have checked it. Thanks. As for the errors, [see this answer](https://reddit.com/r/emacs/comments/tjm6ly/iniline_refined_git_diff_with_live_update_video/i1mc7n4/).

Yes that make sense

Yes, please, just somebody should iron out the remaining bugs. I don't think there are many, but I won't have time to work on this in the near future, that's why I posted the code in case somebody's interested.

I guess it's quicker if someone finishes the code and puts on MELPA, because the core devs have enough things to work on.

"Quicker" doesn't really factor into it, to my mind. Improvements to Emacs are welcomed by the maintainers, and a better default Emacs benefits everyone. You should feel free to propose improvements and provide code.

Does this functionality exist in other editors/IDE's? Is this something others generally find useful? It seems nifty and perhaps useful for minor edits, but would likely end up getting in the way for larger changes. Currently I use hl-diff, then diff-mode / [diff-ansi](https://gitlab.com/ideasman42/emacs-diff-ansi) to get a fuller context of how things have changed.

I like this idea. It can behave a little bit odd, though. For example, if I change the word "coordinate" to "reverse", it doesn't show what I'd expect ("coordinate" is red and "reverse" is green), but several added and removed short strings: "\[coo\]r\[dinat\]\[evers\]e". For a more complex example, the result is even worse. A simple, several-line source code change can create a very messy diff, because it diffs on the character level. Do anyone has an idea how to fix this?

The line "--word-diff-regex=." sets up character-level diffs. You can try commenting out this line to get word-level diffs.

Thanks! I tried it, and it solves the messy diff issue, but introduces another one. If there is "// Something", and I remove the space between the "//" and "Something", then it generates a larger diff than I expected. I'd expect a red space, but it considers that "// Something" was removed, and "//Something" is added. Also, it doesn't show whitespace differences. This idea is great, it just needs additional work. Maybe I'll try to solve these issues, if no one else does. I already created a minor mode out of this, and added a unique overlay category so it doesn't mess up other overlays. And I made the narrowing feature toggleable.
