The chapter introduces an alternative approach to parsing using internal domain-specific languages (DSLs) in Scala, specifically parser combinators. These combinators serve as building blocks for parsers, eliminating the need for standalone parser generators like Yacc or Bison.
An internal DSL for parsing arithmetic expressions using parser combinators in Scala is introduced. The chapter demonstrates creating a parser for arithmetic expressions by leveraging Scala's combinator parsers, incorporating various language features like parameterized types and functions as objects.
