This book shows how we can reuse existing libraries and frameworks to create all the ecosystem necessary to support our languages.

The cost of building all the machinery to proper support a language used to be very high. Today with a limited effort we can design a language and obtain:

a fast parser from a concise grammar definition
validation and model transformations with very few code
generate JVM bytecode and get interoperability with other JVM languages
obtain rich editors with syntax highlighting and autocompletion

We will see how to build all of this and more by defining small components in a smart way. The result will be something solid, complete and understandable.
