Crate hedl_toon 

HEDL ↔ TOON Conversion

Bidirectional conversion between HEDL documents and TOON (Token-Oriented Object Notation) format. Uses the official toon-format crate for spec-compliant parsing and serialization.

Overview

This crate provides conversion between HEDL and TOON using the official TOON parser. TOON is designed for efficient processing by Large Language Models while maintaining human readability.

Quick Start

use hedl_toon::hedl_to_toon;
use hedl_core::Document;

let hedl = r#"%V:2.0
%NULL:~
%QUOTE:"
%S:User:[id, name]
---
users:@User
 |u1, Alice
 |u2, Bob
"#;

let doc = hedl_core::parse(hedl.as_bytes())?;
let toon = hedl_to_toon(&doc)?;
println!("{}", toon);
