neco-toml

日本語

zero dependency TOML subset parser.

Features

• Line-oriented key = value parsing
• Empty values followed by - item lines converted to lists
• Scalar parsing for null, bool, number, and string values
• Field order preserved as Vec<(String, TomlValue)>
• ParseError with line-oriented position and message

Usage

Parse

use neco_toml::{parse, TomlValue};

let value = parse("name = neco").unwrap();
assert!(matches!(value, TomlValue::Map(_)));

Read fields

use neco_toml::{parse, TomlValue};

let value = parse("name = neco").unwrap();
let TomlValue::Map(fields) = value else { panic!("map") };
assert!(fields.iter().any(|(key, value)| {
    key == "name" && matches!(value, TomlValue::String(text) if text == "neco")
}));

API

Format support

The supported subset covers flat configuration-shaped TOML with scalar values and simple arrays. It preserves duplicate keys in source order and does not implement the full TOML v1.0 grammar.
