From 0 to 1: How to Design and Implement Your Own Scripting Language

This article provides a comprehensive guide on designing and implementing a scripting language from scratch. It begins with an introduction to the fundamental concepts of compilation, including the evolution from machine code to high-level programming languages. The article then delves into the core components of a scripting language interpreter, such as lexical scanning, syntax parsing, bytecode generation, and virtual machine execution.

The author uses a hypothetical scripting language called "eben" as a case study to illustrate the process. The article covers topics such as BNF (Backus-Naur Form) syntax, bytecode instructions, virtual machine architecture, variable handling (global and local), control structures (if statements, loops), functions, closures, object-oriented programming, and garbage collection. Each concept is explained with detailed examples and code snippets, making it accessible to readers with a basic understanding of programming.

The article also includes a historical overview of programming languages and their creators, highlighting the evolution of compilation techniques. It concludes with a discussion on the importance of understanding compilation principles and encourages readers to explore further in the field of computer science.
