Overview

Wrapper for regular magic comments not bound to an editor.

Simple comments can only specify one setting per comment.

Examples:

frozen string literal comments

comment1 = RuboCop::MagicComment.parse('# frozen_string_literal: true')
comment1.frozen_string_literal # => true
comment1.encoding              # => nil

encoding comments

comment2 = RuboCop::MagicComment.parse('# encoding: utf-8')
comment2.frozen_string_literal # => nil
comment2.encoding              # => 'utf-8'
