Overview

‘RuboCop::AST::Builder` is an AST builder that is utilized to let `Parser` generate ASTs with Node.

buffer = Parser::Source::Buffer.new('(string)')
buffer.source = 'puts :foo'

builder = RuboCop::AST::Builder.new
require 'parser/ruby25'
parser = Parser::Ruby25.new(builder)
root_node = parser.parse(buffer)
