Constant Summary

LiteralNode =

Immutable AST node for literal values using Ruby’s Data class Because sometimes you just want to say what you mean, immutably

Data.define(:value) do
  def accept(visitor)
    visitor.visit_literal_node(self)
  end

  def to_ast
    self
  end

  # Pattern matching support
  def deconstruct
    [value]
  end

  def deconstruct_keys(_keys)
    { value: value }
  end

  # Type inference
  def inferred_type
    case value
    when String then :string
    when Symbol then :parameter
    when Integer then :integer
    when Float then :float
    when TrueClass, FalseClass then :boolean
    when NilClass then :null
    else :unknown
    end
