Scala Parser Combinators: The Easier Way to Create an External DSL
summary
Shows how Scala parser-combinators builds an external DSL that replaces a bulky XML profile with a concise text format, turning a 115-line XML example into a 32-line DSL equivalent. Implements a 200-line parser that lives next to and produces plain Scala model classes, avoids parser-generator setup, composes small parsers into larger ones, and integrates directly into the application stack — a working, production-oriented parser that reduced boilerplate and improved readability.
