Comp407: Compiler Construction Study Guide

This repository contains the collected labs, resources, and study materials for the Comp407 Compiler course. It is organized to support the weekly progression of the course, with each lab isolated in its own directory.

⚡ Quick Start (VS Code)

To build and run a lab instantly:

1. Open a grammar file (e.g., labs/lab03/grammar/lab03.g).
2. Press Ctrl+Shift+B and select "Java: Compile Lab".
3. To run, use the "Run Current Lab" task (accessible via F1 > Run Task).

📂 Repository Structure

The project follows a standardized layout to keep things clean and predictable:

• lib/: Contains core dependencies (antlr-3.4-complete.jar).
• labs/: The core coursework, numbered by week:
  • grammar/: ANTLR grammar files (.g).
  • src/: Your handwritten Java code (e.g., Main.java).
  • tests/: Sample input files (.txt) to test your parser.
  • output/: Generated and compiled artifacts (Git-ignored).
• resources/: General course-wide study guides and exercises.

🛠️ How to Run Manually

If you prefer using the terminal, run these commands from the root of the repository.

1. Generate Parser

java -jar ./lib/antlr-3.4-complete.jar -o ./labs/lab01/output/ ./labs/lab01/grammar/lab01.g

2. Compile Java

javac -cp ".:./lib/antlr-3.4-complete.jar" -d ./labs/lab01/output/ ./labs/lab01/src/*.java ./labs/lab01/output/*.java

3. Run Program

java -cp ".:./lib/antlr-3.4-complete.jar:./labs/lab01/output/" Main
