ronin-core

The lossless, error-tolerant RON (Rusty Object Notation) concrete-syntax-tree engine that powers RONin.

ronin-core parses RON text into a full-fidelity CST (built on rowan) that preserves every byte — comments, whitespace, ordering, and trailing commas — so print(parse(src)) == src. Parsing is error-tolerant (it recovers and reports diagnostics rather than failing), and the crate exposes a typed AST, structural-edit transforms, a deterministic formatter, and a bounded CST-backed undo stack.

It is the WASM-clean core of the workspace: its only dependency is rowan, with no filesystem, UI, async-runtime, or network code, so it builds for wasm32-unknown-unknown and is reusable by future frontends (LSP, browser/VSCode).
