Written by Clinton L Jeffery, the creator of the Unicon programming language, this book will show you how to implement domain-specific programming languages to reduce the time and cost of creating applications for new or specialized areas of computing. Jeffrey starts with implementing the frontend of a compiler for your language, including a lexical analyzer and parser, including the handling of parse errors.

The book then covers a series of traversals of syntax trees, culminating with code generation for a bytecode virtual machine or native code. It also shows how to manage data structures and output code when writing a preprocessor or a transpiler.
