ANTLR Fundamentals: Defining Grammars and Generating Parsers

Do you need to process complex structured text, create a domain-specific language, or understand how compilers work? ANTLR is the industry standard tool for language recognition. This course provides a clear, text-based introduction to ANTLR, enabling you to design, implement, and test custom grammars. You will gain the practical skills necessary to transform written specifications into functional parsing tools capable of validating and interpreting input data. What you'll learn: * Understand the core concepts of language recognition, including tokenization, lexing, and parsing. * Design and write robust ANTLR grammars, distinguishing between lexer rules and parser rules. * Apply Listeners and Visitors to traverse the abstract syntax tree (AST) and execute custom logic. * Practice resolving common grammar issues like ambiguity and left recursion using ANTLR features. * Configure and integrate generated parsers into various programming language environments for practical use. The course begins with defining key terminology and setting up the ANTLR environment. We then move step-by-step through writing simple grammars, generating parser code, and implementing tree traversal patterns using practical, textual examples. This course is intended for software developers and computer science students who are beginners in compiler design and language processing. No prior experience with ANTLR or formal grammar definition is required. Start reading now to build your first language recognition tool.
