Crate yamp 

YAMP - Yet Another Minimal Parser

A lightweight, efficient YAML parser that treats all scalar values as strings, avoiding YAML’s numerous type-related pitfalls.

Features

• All scalar values are strings (no implicit type conversion)
• Supports basic YAML structures (objects, arrays, scalars)
• Preserves comments during parsing
• Supports multiline strings (literal | and folded >)
• Zero dependencies
• Predictable, secure behavior

Example

use yamp::{parse, emit, YamlValue};
use std::borrow::Cow;

let yaml = "name: John\nage: 30";
let parsed = parse(yaml).expect("Failed to parse");

// Using the new helper methods for cleaner access
if let Some(name) = parsed.get("name").and_then(|n| n.as_str()) {
    assert_eq!(name, "John");
}

// Or using the traditional approach
if let YamlValue::Object(map) = &parsed.value {
    let age = &map.get(&Cow::Borrowed("age")).unwrap().value;
    // Note: age is a string "30", not a number
    assert_eq!(age, &YamlValue::String(Cow::Borrowed("30")));
}

let output = emit(&parsed);
