Class Method Summary

• .build_ast(tokens : Array(Token)) : AST::Node

  ------------------------------------------------------------------------- Build AST from flat token list using the Shunting Yard algorithm.

• .clear_expression(expression : String)

  ------------------------------------------------------------------------- Legacy methods kept for internal backward compatibility -------------------------------------------------------------------------

• .compile(expression : String) : AST::Node

  ------------------------------------------------------------------------- Compile only: return AST root for repeated evaluation -------------------------------------------------------------------------

• .evaluate(expression : String)
• .has_left_associativity(operator : String) : Bool
• .parse(expression : String, env : Hash(String, Float64)) : Float64

  ------------------------------------------------------------------------- High-level parse: tokenize → build AST → evaluate with env -------------------------------------------------------------------------

• .precedence(operator : String) : Int32

  ------------------------------------------------------------------------- Operator helpers (unchanged) -------------------------------------------------------------------------

• .should_pop?(op1 : String, op2 : String) : Bool
• .tokenize(expression : String) : Array(Token)

  Tokenizes an infix expression string into an Array of Token.
