The repository for the book 'Crafting Interpreters', containing the full Markdown text, a static site generator, and complete implementations of two interpreters (jlox in Java and clox in C) for the Lox scripting language. It teaches readers how to build a full-featured, dynamically typed language from scratch, covering parsing, bytecode compilation, and garbage collection.

Use cases

• learn how to write an interpreter for a programming language
• understand how bytecode virtual machines work
• build my own scripting language from scratch
• learn parsing and lexical analysis hands-on
• study garbage collection implementation in C
• find a tutorial on compilers and language design
• implement closures and classes in a language runtime

When to choose

• you want a hands-on, code-first introduction to interpreters and language implementation
• you prefer learning by writing every line of a real language yourself
• you want a free, complete book covering both tree-walking and bytecode VM approaches

When to avoid

• you need a production-ready interpreter or compiler toolchain
• you want formal compiler theory rather than practical implementation
• you need a maintained software tool - this is primarily a book, not a library
