Learn to design your own programming language in a hands-on way by building compilers, using preprocessors, transpilers, and more, in this fully-refreshed second edition, written by the creator of the Unicon programming language.Purchase of the print or Kindle book includes a free PDF eBookKey Features- Takes a hands-on approach; learn by building the Jzero language, a subset of Java, with example code shown in both the Java and Unicon languages- Learn how to create parsers, code generators, scanners, and interpreters- Target bytecode, native code, and preprocess or transpile code into a high-level languageBook DescriptionThere are many reasons to build a programming language: out of necessity, as a learning exercise, or just for fun. Whatever your reasons, this book gives you the tools to succeed.You'll build the frontend of a compiler for your language and generate a lexical analyzer and parser using Lex and YACC tools. Then you'll explore a series of syntax tree traversals before looking at code generation for a bytecode virtual machine or native code. In this edition, a new chapter has been added to assist you in comprehending the nuances and distinctions between preprocessors and transpilers. Code examples have been modernized, expanded, and rigorously tested, and all content has undergone thorough refreshing. You'll learn to implement code generation techniques using practical examples, including the Unicon Preprocessor and transpiling Jzero code to Unicon. You'll move to domain-specific language features and learn to create them as built-in operators and functions. You'll also cover garbage collection.Dr. Jeffery's experiences building the Unicon language are used to add context to the concepts, and relevant examples are provided in both Unicon and Java so that you can follow along in your language of choice.By the end of this book, you'll be able to build and deploy your own domain-specific language.What you will learn- Analyze requirements for your language and design syntax and semantics.- Write grammar rules for common expressions and control structures.- Build a scanner to read source code and generate a parser to check syntax.- Implement syntax-coloring for your code in IDEs like VS Code.- Write tree traversals and insert information into the syntax tree.- Implement a bytecode interpreter and run bytecode from your compiler.- Write native code and run it after assembling and linking using system tools.- Preprocess and transpile code into another high-level languageWho this book is forThis book is for software developers interested in the idea of inventing their own language or developing a domain-specific language. Computer science students taking compiler design or construction courses will also find this book highly useful as a practical guide to language implementation to supplement more theoretical textbooks. Intermediate or better proficiency in Java or C++ programming languages (or another high-level programming language) is assumed.

In computer science, the primary application of visualization technology is software visualization: the use of graphics to portray information obtained from a static or dynamic analysis of a program. Software visualization is used in several phases of the software development lifecycle, but it is of particular interest in the "e;back- end"e; tasks of debugging, performance tuning, and understanding complex systems in order to maintain them. Software visualization is expected to improve the back end of the software development process which can result in huge cost savings. Debugging, tuning and maintaining programs comprise the majority of the high costs associated with software development. Unfortunately, the rate at which these software technologies have improved has been gradual. The task of writing software visualization tools is difficult, and most existing systems are limited to a narrow scope, such as the visualization of a single well-understood algorithm from a hand-instrumented source program. This book presents software visualization at a level suitable for a senior level undergraduate or graduate course or for the interested technical professional. The approach is to give a survey of the field, and then present a specific research framework designed to reduce the effort required to write visualization tools. A wide range of simple program control flow and data structure visualizations are then presented as examples of how to obtain information about program behavior, and how to present it graphically. Source code fragments and screen images illustrate each example.

Build Your Own Programming Language provides a hands-on approach to designing language features and implementing those features in a simple compiler and programming environment. This book will help you create new or domain-specific languages that include lexical syntax, semantic analysis, parse trees, tree traversals, and code generation.
