Writing an Interpreter in Object Pascal

Writing an Interpreter in Object Pascal

The book provides fully working code and explains in plain English how the code works and why certain decisions were made, including alternative designs. The book makes liberal use of code throughout the book chapters.

This is part 1 of a series that will show you how to write an interactive interpreter in Object Pascal. Part 1 of the series will cover introductory material including a description of the language we'll create, a full lexical analyzer for the language, how to use DUnitX for unit testing, and an introduction to the essential concepts in syntax analysis, recursive descent, grammar, and EBNF. Along the way, we'll create a REPL, give a detailed discussion of how to parse expressions and build a simple interactive calculator to illustrate the theory. The book provides fully working code and explains in plain English how the code works and why certain decisions were made, including alternative designs. The book makes liberal use of code throughout the book chapters. Everything is done without the help of third-party tools. All you need is a standard installation of Free Pascal or Embarcaderos's excellent Delphi (including the free community edition). The text is geared to hobbyists and midlevel developers who need an easy introduction to lexical analysis and parsing. It's also for students starting out in compiler and interpreter design and need something more digestible before getting immersed in compiler theory.

Long-awaited revision to a unique guide that covers both compilers and interpreters Revised, updated, and now focusing on Java instead of C++, this long-awaited, latest edition of this popular book teaches programmers and software engineering students how to write compilers and interpreters using Java. You?ll write compilers and interpreters as case studies, generating general assembly code for a Java Virtual Machine that takes advantage of the Java Collections Framework to shorten and simplify the code. In addition, coverage includes Java Collections Framework, UML modeling, object-oriented programming with design patterns, working with XML intermediate code, and more.

While there are many books on particular languages, there are very few that deal with all aspects of object-oriented programming languages. The Interpretation of Object-Oriented Programming Languages provides a comprehensive treatment of the main approaches to object-oriented languages, including class-based, prototype and actor languages. This revised and extended edition includes a completely new chapter on Microsoft's new C# language, a language specifically designed for modern, component-oriented, networked applications. The chapter covers all aspects of C# that relate to object-oriented programming. It now also includes a new appendix on BeCecil, a kernel language that can implement object-oriented constructs within a single framework.
