Crate slr_config

This crate implements the parsing for the SLRConfig format. Basic usage revolves around the creation and use of the ConfigElement type, like so:

#[macro_use]
extern crate slr_config;

use slr_config::{ConfigElement, ElementRepr};
use std::path::Path;

fn main()
{
    // Parse config element from value.
    let root = ConfigElement::from_str("key = value").unwrap();
    assert_eq!(root.as_table().unwrap()["key"].as_value().unwrap(), "value");

    // Create a new table and print it to a string.
    let mut root = ConfigElement::new_table();
    let val = ConfigElement::new_value("value");
    root.insert("key", val);
    assert_eq!(root.to_string(), "key = value\n");

    // Compile-time schemas automate the above process in many situations.
    slr_def!
    {
        struct TestSchema
        {
            key: u32 = 0,
            arr: Vec<u32> = vec![]
        }
    }

    let mut schema = TestSchema::new();
    schema.from_element(&ConfigElement::from_str("key = 5, arr = [1, 2]").unwrap(), None).unwrap();
    assert_eq!(schema.key, 5);
    assert_eq!(schema.arr.len(), 2);
    assert_eq!(schema.arr[0], 1);
    assert_eq!(schema.arr[1], 2);

    let elem = schema.to_element();
    assert_eq!(elem.as_table().unwrap()["key"].as_value().unwrap(), "5");
    assert_eq!(elem.as_table().unwrap()["arr"].as_array().unwrap()[0].as_value().unwrap(), "1");
}
