Practical Interpreter Construction

Learn How to Craft An Interpreter The Practical Way

About the Book

Despite the fact that interpreters are in every single computer system, only rare programmers are able to design and write them. Constructing and coding an interpreter needs different mental processes and experience. The programmer must understand the internals of the programming languages, compilers and the computer. This book is for programmers who have always wanted to learn to write their own interpreter but kept away because of dull, theory heavy and difficult to understand books.  It is written by a pragmatic programmer using first person language with a theory-free attitude. By reading this book, you will learn tokenizing, parsing and finally interpreting source code. All of these separate parts of the interpreter give you different skills you can benefit from in your whole programming career.
