StringDVar represents shorthand interpolation of a variable into a string. It allows you to take an instance variable, class variable, or global variable and omit the braces when interpolating.

"#@variable"

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

def ===(other)
  other.is_a?(StringDVar) && variable === other.variable
end

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

def child_nodes
  [variable]
end

def copy(variable: nil, location: nil)
  node =
    StringDVar.new(
      variable: variable || self.variable,
      location: location || self.location
    )

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

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

def format(q)
  q.text('#{')
