Build a Programming Language Parser

Have you ever wondered how programming languages understand the code you write? The secret lies in parsing, the crucial first step in turning human-readable text into machine-interpretable instructions. This course will guide you through the foundational principles and practical steps of building a parser, enabling you to transform raw source code into structured data that your own programming language can process. What you'll learn: * Understand the core concepts of lexical analysis and syntactic parsing. * Implement a tokenizer to convert source code into a stream of tokens. * Apply parsing techniques to correctly identify and process identifiers, numbers, and strings. * Construct a basic Abstract Syntax Tree (AST) to represent the hierarchical structure of parsed code. * Incorporate fundamental error handling mechanisms for a more robust parser. * Practice building a functional parser through clear, written examples and exercises. You will begin by exploring essential terminology and theoretical foundations, then progressively build a practical parser by implementing each component step-by-step using only written explanations and code snippets. This course is ideal for beginners with basic programming knowledge who are curious about how programming languages work and want to build their own language components. Embark on your journey to understand and create programming languages from the ground up.
