@younndai/yon is the convenience entry point for the YON toolchain — install one package and get the parser, generator, runner, converter, domain schemas, AI relay, examples, and benchmarks. Prefer to pull only what you need? Every tool also ships as its own package — install those directly instead.

Install

npm install @younndai/yon

Use

Import the tools by namespace from the meta-package:

import { parser, generator, runner } from "@younndai/yon";

const ast = parser.parse(source);

…or import directly from each package — both styles work and resolve to the same code:

import { parse } from "@younndai/yon-parser";

What's included

| Namespace | Package | What it does | |---|---|---| | parser | @younndai/yon-parser | Parse, validate, and format YON | | generator | @younndai/yon-generator | Build valid YON documents from code | | runner | @younndai/yon-runner | Execute YON workflows | | converter | @younndai/yon-converter | Convert between YON and JSON/CSV/INI | | domains | @younndai/domains | Official domain schemas (fetch / validate / classify) | | aiRelay | @younndai/ai-relay | Provider-agnostic LLM gateway | | examples | @younndai/yon-examples | Example corpus | | benchmarks | @younndai/yon-benchmarks | Performance benchmark suite |

The normative specification lives separately in @younndai/yon-spec — the tools above depend on it.
