Contains the classes needed by [RuboCop](https://github.com/rubocop-hq/rubocop) to deal with Ruby's AST, in particular:
* `RuboCop::AST::Node`
* `RuboCop::AST::NodePattern` ([doc](docs/modules/ROOT/pages/node_pattern.adoc))

This gem may be used independently from the main RuboCop gem. It was extracted from RuboCop in version 0.84 and its only
dependency is the `parser` gem, which `rubocop-ast` extends.

## Installation

Just install the `rubocop-ast` gem

```sh
gem install rubocop-ast
```

or if you use bundler put this in your `Gemfile`

```ruby
gem 'rubocop-ast'
```

## Usage

Refer to the documentation of `RuboCop::AST::Node` and [`RuboCop::AST::NodePattern`](docs/modules/ROOT/pages/node_pattern.adoc)

### Parser compatibility switches

The main `RuboCop` gem uses [legacy AST output from parser](https://github.com/whitequark/parser/#usage).
This gem is meant to be compatible with all settings. For example, to have `-> { ... }` emitted
as `LambdaNode` instead of `SendNode`:

```ruby
RuboCop::AST::Builder.emit_lambda = true
```
