word diff / color-words

[mustafa0x]

There are a few Javascript libraries for performing word diffs, but they're all 10-100x times slower than git diff --word-diff for large documents[1]. Does gitoxide have word-diff functionality (libgit2 doesn't seem to yet)? Does it plan to? Could it be compiled to WASM and used as a self-contained library / method? Is there anything similar for diffing large documents in the browser at the speed of git diff?

[1]: The most performant seems to be diff-match-patch. It remains far slower. Even the C++ implementation is several times slower than git diff.

Thanks for your interest - diffing in gitoxide is definitely in its early stages right now.

Does gitoxide have word-diff functionality (libgit2 doesn't seem to yet)? Does it plan to?

Yes! Currently git-diff can calculate differences between trees, which is the basis to seeing which files changed. These can then be word-diffed with any algorithm, which could already be done with crates on crates.io or the library version of delta.

Could it be compiled to WASM and used as a self-contained library / method?

WASM isn't yet a compilation target and getting gitoxide there is going to be some work. It's going to happen eventually though, even though there isn't a tracking ticket yet, it's tracked in #463 in case you want to stay in the loop.
