SER502-Funlang-Team29

Overview:

• This repository contains the source code, documentation, and demonstration materials for the implementation of "Funlang", a custom programming language designed and developed as part of a team project for the SER502 course.
• Dive into FUNLANG – a programming language designed to make writing code simpler, intuitive, and, most importantly, fun with every line of code.

Basic flow

TOOLS that are used:

• The parsing technique that we would be utilizing for the project is a ‘Top-down’ descent parser. This is the common approach for parsing context-free grammars.
• Recursive Descent Parser: Each non-terminal in grammar corresponds to a parsing function. These functions recursively call each other to parse the input according to the grammar rules defined.

Instructions/Steps to install:**

MacOS (Need to install Homebrew):

homebrew install swi-prolog

Python: refer to https://www.python.org/downloads/

Src folder elements:

• grammar.pl: grammar for Funlang
• tokenize.py: takes Funlang source code as input and generates a list of tokenized code with special characaters as seperate tokens
• parser.pl: takes a list of Funlang tokenized code as input and generates an appropriate parsed tree based on our grammar
• Evaluator.pl: takes a parsed Funlang program tree as input and evaluates the program
• run_program.sh: one liner bash script to invoke the parser and evaluator

How to run the one liner bash script:

./run_program.sh <file-path>/<file-name>
