# ParserNodeExt

[![Build Status](https://github.com/synvert-hq/parser_node_ext/actions/workflows/main.yml/badge.svg)](https://github.com/synvert-hq/parser_node_ext/actions/workflows/main.yml)

[![Gem Version](https://img.shields.io/gem/v/parser_node_ext.svg)](https://rubygems.org/gems/parser_node_ext)

It assigns names to the child nodes of the [parser](https://rubygems.org/gems/parser).

```ruby

# node is a send node

node.receiver # get the receiver of node

node.message # get the message of node

node.arguments # get the arguments of node

```

It also adds some helpers

```ruby

# node is a hash node

node.foo_pair # get the pair node of hash foo key

node.foo_value # get the value node of the hash foo key

node.foo_source # get the source of the value node of the hash foo key

node.keys # get key nodes of the hash node

node.values # get value nodes of the hash node

# all nodes

node.to_value # get the value of the node, like `true`, `false`, `nil`, `1`, `"foo"`

node.to_source # get the source code of the node

```
