Build a Programming Language and CLI Interpreter

Have you ever wondered how programming languages function at their core, or how command-line tools process your instructions? This course demystifies the entire process, guiding you through the creation of your own simple programming language and its custom command-line interface (CLI) interpreter. By the end of this course, you will possess a clear understanding of language design principles, interpreter development, and how to build interactive command-line applications. You'll be able to bring your own miniature programming language to life, executing its code directly from your terminal. What you'll learn: * Understand the fundamental components of a programming language, from lexing to execution. * Design a simple language syntax and define its operational semantics. * Implement a parser to transform source code into an Abstract Syntax Tree (AST). * Develop an interpreter capable of executing your custom language's programs. * Create a command-line interface (CLI) to run your language files, including modern argument parsing. * Apply basic error handling and reporting techniques for a robust language implementation. The course begins with an exploration of core terminology and foundational concepts in language theory and CLI design. From there, you will progressively build each component of your language and its interpreter through clear, step-by-step written explanations and practical code snippets. This course is designed for absolute beginners with no prior experience in language design, compiler theory, or advanced CLI development. Start your journey into the fascinating world of programming language creation.
