tur-json

JSON parsing and serialization for Turmeric via yyjson: parse, emit, and in-place patch (get-in / set-in / merge).

Overview

tur-json is a Tier 3 spice (cmake-dep -- pulls in yyjson 0.10.0 via tur fetch). It wraps yyjson's fast SAX/DOM parser behind a small Turmeric surface: json-parse returns a result<doc>, json-emit / json-emit-pretty serialize back to text, and the json/patch module exposes dotted-path read/write helpers.

Use it for application config, REST payloads, and any JSON I/O where you want yyjson's speed without dropping to inline C.
