var rspath = require('rspath');

// Simple

var obj = {
    a: true
};

console.log(rspath.pathGet(obj, 'a'));

rspath.pathSet(obj, 'a', false);
console.log(rspath.pathGet(obj, 'a'));

rspath.pathSet(obj, 'a', { hello: 'world' });
console.log(rspath.pathGet(obj, 'a'));

rspath.pathDelete(obj, 'a.hello');
console.log(rspath.pathGet(obj, 'a.hello'));

console.log(rspath.pathGet(obj, 'a'));

// Arrays

obj = {
    a: true,
    b: {
        ba: [],
        bb: [0, 1, 2, 3, 4]
    }
};

console.log(rspath.pathGet(obj, 'b'));
console.log(rspath.pathGet(obj, 'b.bb'));
console.log(rspath.pathGet(obj, 'b.bb[0]'));
console.log(rspath.pathGet(obj, 'b.bb[1]'));
console.log(rspath.pathGet(obj, 'b.bb[2]'));
console.log(rspath.pathGet(obj, 'b.bb[3]'));
console.log(rspath.pathGet(obj, 'b.bb[4]'));
console.log(rspath.pathGet(obj, 'b/bb[4]', '/'));

// Arrays and Objects

    a: true,
    b: {
        ba: [{
            baa: [0, 1, 2, 3, 4]

console.log(rspath.pathGet(obj, 'b'));
console.log(rspath.pathGet(obj, 'b.ba[0].baa[3]'));
console.log(rspath.pathGet(obj, 'b.ba[1].bab[4]'));
console.log(rspath.pathGet(obj, 'b.ba[1].bab[5]'));
console.log(rspath.pathGet(obj, 'b.ba[2]'));
console.log(rspath.pathGet(obj, 'b.ba[2].bac[4]'));
