Explore why someone would build a new interpreter, examine the aspects that influence the design of the runtime and of the programming language, and work through the steps to concretely implement the interpreter.
Key Features
Design a programming language to solve a particular problem, rather than a general-purpose one Follow a bottom-up approach, from designing runtime to building a language-specific interpreter Build an interpreter from scratch, focusing on achieving a minimally viable product
Book DescriptionDesigning a custom programming language can be the most effective way to solve certain types of problemsespecially when precision, safety, or domain-specific expressiveness matters. This book guides you through the full process of creating your own language and interpreter, from design to implementation, using modern C++.
Youll start by exploring when and why building a language is worth it, and how to design one to match a specific problem domain. Along the way, youll examine real-world interpreter architectures and how their design decisions affect language capabilities.
The book then walks through the entire process of building an interpreter: defining the syntax, building a parser and semantic model, designing an abstract syntax tree, generating executable instructions, and implementing a runtime. All examples are in modern C++, with a focus on clean architecture and real-world usability.
By the end, youll have a fully working interpreter for a domain-specific language designed to handle network protocolsplus the knowledge and tools to design your own language from scratch. What you will learn
Gain hands-on experience building a programming language from scratch Write an interpreter that can be embedded into existing environments Reason about similarities and distinctions in programming languages Understand the execution models of different languages Identify the requirements for the runtime environment of an interpreter Implement a lexer, parser, analyzer, and execution instruction emitter
Who this book is forThis book is tailored for intermediate to advanced software developers, particularly those interested in language design and implementation. It's ideal for programmers seeking to expand their skill set and tackle complex problems efficiently. Professionals working in roles such as software engineers, language designers, or system architects will benefit from the practical insights and hands-on experience provided in the book. Good understanding of C++ programming and basic understanding of language design concepts are recommended to fully grasp the content.
