A YAML parser that represents YAML as a hierarchical structure of nodes and tokens.

Purpose
-------

[](#purpose)

The library enables working with YAML not only as data but as a full structure of the source text represented by nodes and tokens. It provides base layer for the analysis and modification of YAML with isolated impact and without side effects.

Unlike [`symfony/yaml`](https://github.com/symfony/YAML), which is designed for `YAML → array`and `array → YAML` conversion, this library provides a mechanism for analyzing and precisely manipulating the source YAML.
