Designing Grammars with ANTLR for Language Processing

Learning how computers interpret structured text is a powerful skill for any developer. ANTLR is the industry standard tool for generating parsers that can read, validate, and process complex language inputs. By the end of this course, you will understand the principles of formal language definition and parser generation. You will gain practical experience writing ANTLR grammars, implementing lexer rules, and structuring parser rules to reliably analyze input text and prepare it for further application logic. What you'll learn: * Understand the core components of a grammar, including lexers, tokens, and parser rules. * Practice defining context-free grammars using sequences, alternatives, and repetition operators. * Apply advanced parsing features like predicates and semantic actions for complex language requirements. * Configure robust error handling and recovery strategies within your ANTLR grammar definitions. * Build the foundational structure for traversing the generated Abstract Syntax Tree (AST) to implement application logic. The course begins with defining the anatomy of a language and core ANTLR concepts before moving into practical rule definition and structure. We guide you through applying these rules to create a complete, functional grammar that handles both valid and invalid input. This course is designed for beginner developers, data engineers, and software architects who need to process structured data or define custom Domain-Specific Languages (DSLs). No prior experience with compiler construction or parsing tools is required. Start defining your own custom language processors today.
