Create and publish a library crate

[petr-tik]

Hey Wilfred,
Thanks for such a great command-line tool.

I was wondering if you would consider publishing a library with your work to provide an interface similar to dissimilar's diff
https://docs.rs/dissimilar/1.0.3/dissimilar/fn.diff.html

It would really help people writing tests that calculate and highlight diffs to have AST-powered diffs. I am thinking rust-analyzer and the myriad of text editors being implemented in rust atm.

Appreciate all your work here - thanks again

I would like to see a ‘assert_eq’ macro

Hello, sorry to bump this issue but it would indeed be a great idea.
Any idea on the advancement of this ?

I would like to create new git tooling with git2 crate and difftastic would immensely help to get better diffs.
As the code is already in rust, having it as a crate would help rather than hack stuff around sub-processes etc...

Also, it would help people to maybe create bindings to like python and stuff.

Thanks in advance,
Have a nice day :)
