## Usage

```js

const { yamlAST, loc } = require('pseudo-yaml-ast');

const assert = require('assert');

const ast = yamlAST(`

  obj:

    arr:

    - nums:

      - 1

      - 2

      - 3

      strs1:

      - '1'

      - '2'

      - '3'

    str: '1'

    num: 1

`);

assert.deepEqual(Object.keys(ast), ['obj']);

assert.deepEqual(ast[loc].start.line, 2);

assert.deepEqual(ast[loc].end.line, 14);

assert.deepEqual(Object.keys(ast.obj), ['arr', 'str', 'num']);

assert.deepEqual(ast.obj[loc].start.line, 2);

assert.deepEqual(ast.obj[loc].end.line, 13);

assert.deepEqual(ast.obj.str[loc].start.line, 12);

assert.deepEqual(ast.obj.str[loc].end.line, 12);

assert.deepEqual(ast.obj.num[loc].start.line, 13);

assert.deepEqual(ast.obj.num[loc].end.line, 13);

assert.deepEqual(ast.obj.arr[0][loc].start.line, 4);

assert.deepEqual(ast.obj.arr[0][loc].end.line, 12);

assert.deepEqual(Object.keys(ast.obj.arr[0]), ['nums', 'strs1']);

assert.deepEqual(ast.obj.arr[0].nums[loc].start.line, 4);

assert.deepEqual(ast.obj.arr[0].nums[loc].end.line, 8);

assert.deepEqual(ast.obj.arr[0].strs1[loc].start.line, 8);

assert.deepEqual(ast.obj.arr[0].strs1[loc].end.line, 12);
