Project Overview:

This project is a Context-Free Grammar (CFG) parser implemented in Prolog. It parses source code written in a specific grammar defined in the project and checks for syntax errors.

Features:

• Parsing: Parses source code according to the defined CFG rules.
• Error Checking: Identifies syntax errors in the source code.
• Input: Reads source code from a file.
• Output: Prints the parsed tokens and identifies if the code is syntax-free or contains errors.

Usage:

1. Ensure you have a Prolog interpreter installed on your system.
2. Clone or download the project files to your local machine.
3. Open your Prolog interpreter and consult the main file (e.g., main.pl).
4. Run the parser predicate to start parsing the source code.
5. Provide the path to the source code file when prompted.

Project Structure:

• main.pl: Main Prolog file containing the parser logic and predicates.
• grammar.pl: Defines the CFG rules for parsing.
• input.txt: Example input file containing source code to be parsed.

Example Usage:

?- parser.
Enter the path to the source code file: input.txt.
