git diff

[dalduba]

Is there a chance that "git diff" will be implemented?

[dalduba]

The case is:
Edit some heavy data in a browser, send only diff to the server when saving.

No, it will never be implemented because it requires a Diff library and it's out of scope. You can use Diff library of your choice (like jsDiff) and implement git diff yourself.

Check my project where I've added git diff without any issues using existing API, even before version 1.0

Thanks for your reply. Could you suggest a library for "git apply" implementation on js?

[dalduba]

Found, that jsdiff has Api for applying patches too.

But seems that jsDiff works only with text. May be you know solutions for binary data?

[jcubic]

I don't think that you can diff binary data in canonical git

[dalduba]

"--binary" key enables binary patches generation

You will need to write your own library in JavaScript to create binary patches. But the git source code is Open Source so you can look at how it was implemented and translate that into JavaScript.
