What This Document Is
This document provides focused instruction on the Parser phase – Phase 2 – of compiler construction, as taught in CISC 672 at the University of Delaware. It delves into the critical role of parsing within the broader compilation process, building upon foundational knowledge established in earlier phases. The material centers around practical implementation using parser generator tools and the resulting Abstract Syntax Tree (AST) representation.
Why This Document Matters
This resource is essential for students actively engaged in building a compiler. It’s particularly valuable when you’re ready to translate a defined grammar into executable code and begin structuring the program’s representation. Students who are struggling to connect theoretical grammar concepts with practical parser implementation will find this a helpful guide. It’s best utilized *after* a solid understanding of lexical analysis and formal grammars has been established. Accessing the full content will empower you to move forward confidently in your compiler construction project.
