Crate frostwalker

A TOML-like configuration language parser that supports single depth arrays, integers, strings and boolean literals.

This library isn’t intended to compete with toml. Frostwalker and toml have differing goals and I would recommend you use toml over Frostwalker as it supports more features, but Frostwalker has no dependencies apart from the standard library.

The use of this library is easy and doesn’t require much work:

use frostwalker::parse;

let parsed_output = parse("yes = true\r\nkey = \"value\"\r\narray = [ 1, 5 ]");
let hashmap = parsed_output.unwrap();
assert_eq!(hashmap.get("yes").unwrap(), "true");

assert_eq!(hashmap.get("key").unwrap(), "value");

assert_eq!(hashmap.get("array").unwrap(), "2");
assert_eq!(hashmap.get("array[0]").unwrap(), "1");
assert_eq!(hashmap.get("array[1]").unwrap(), "5");
