In this final chapter, we will build a fully functioning DSL and integrate it into a web application. In doing so, we will cover the issues you will encounter when integrating your own DSLs into existing applications. The DSL we will look at is a proof of concept DSL that implements a simple state machine style game engine with server-side engine logic, which supports a HTML user interface.
The DSL was written to support teaching Groovy, so we will start by looking at how we can use DSL techniques to help with teaching programming to kids
We will see how those ideas evolved into the proof of concept game engine DSL we will build in this chapter
We will look at how we can structure the game engine as a pattern of Groovy classes and then see how we can implement an AST transform to generate that pattern
We will see how we can integrate the DSL into a spring boot game server with a MongoDB session store
Finally, we will build a simple mobile UI for the game with HTML5...
