What is Tree-sitter and how does it work?

Tree-sitter builds fast, incremental parse trees for code—powers editors, now diffs. Parses to CSTs, enabling structural views.

How do structural diffs improve on git diff?

They ignore formatting noise, focus semantics—70% smaller diffs, faster reviews.

Will Git ever support structural hashing natively?

Not soon, but plugins and forks bridge the gap; big players like GitHub are eyeing it.
