In these pages, we will walk step-by-step through two complete interpreters for a full-featured language. I assume this is your first foray into languages, so I’ll cover each concept and line of code you need to build a complete, usable, fast language implementation.

Provides for having Java-like snippets interpreted at runtime. If you need a bit more than that, then consider embedding e.g. JPython or another small interpreter.

Explore the Interpreter Design Pattern in Java with real-world examples, class diagrams, and step-by-step implementation. Learn when and how to use this powerful behavioral pattern.

Basically we need two things for our very simple interpreter: The parser. It’s job is to consume a stream of character and create a higher level representation of our program. The interpreter. It takes the higher representation produced by the parser and executes it. A grammar. This defines the structure of our language. A parser generator.
