The Basic Idea in Code Assume: class StandardTokenParsers { type Parser = Input ⇒ ParseResult where type Input = Reader[Token] // a stream <strong>of</strong> Tokens with positions. and we assume a class Token with subclasses ⊲ case class Keyword(chars : String) for keywords, ⊲ case class NumericLit(chars : String) for numbers, ⊲ case class StringLit(chars : String) for strings, ⊲ case class Identifier(chars : String) for identifiers. 30
In each case, chars represents the characters making up the token. 31
