Formatter

Problem

Formatters must reproduce code with canonical spacing without changing meaning.

Why tree-sitter.zig helps

The tree gives exact spans for every construct; named/anonymous distinctions tell layout rules where whitespace is significant.

API

TreeCursor walk emitting node.text() plus layout rules per type.

Architecture

Parse → walk → emit with spacing rules → verify by reparse
