1. SyntaxTree::
2. AliasNode

Alias represents the use of the alias keyword with regular arguments (not global variables). The alias keyword is used to make a method respond to another name as well as the current one.

alias aliased_name name

For the example above, in the current context you can now call aliased_name and it will execute the name method. When you’re aliasing two methods, you can either provide bare words (like the example above) or you can provide symbols (note that this includes dynamic symbols like :“left-#{middle}-right”).

def initialize(left:, right:, location:)
  @left = left
  @right = right
  @location = location
  @comments = []
end

def ===(other)
  other.is_a?(AliasNode) && left === other.left && right === other.right
end

def accept(visitor)
  visitor.visit_alias(self)
end

def child_nodes
  [left, right]
end

def copy(left: nil, right: nil, location: nil)
  node =
    AliasNode.new(
      left: left || self.left,
      right: right || self.right,
      location: location || self.location
    )

  node.comments.concat(comments.map(&:copy))
  node
end

def deconstruct_keys(_keys)
  { left: left, right: right, location: location, comments: comments }
end

def format(q)
  keyword = "alias "
  left_argument = AliasArgumentFormatter.new(left)

  q.group do
    q.text(keyword)
    q.format(left_argument, stackable: false)
    q.group do
      q.nest(keyword.length) do
        left_argument.comments.any? ? q.breakable_force : q.breakable_space
        q.format(AliasArgumentFormatter.new(right), stackable: false)
      end
    end
  end
end

def var_alias?
  left.is_a?(GVar)
end
