UniC: A C Compiler Frontend

UniC is a C compiler frontend implemented in Python, comprising a Lexer, Parser, Semantic Analyzer, and Symbol Table Manager.

Overview

This project was developed as part of the Compiler Design lab sessional during my BTech IT undergraduate course. UniC aims to provide a basic C compiler frontend, demonstrating the fundamental concepts of compiler design.

Features

• Lexer: Tokenizes C source code into lexical units
• Parser: Parses tokens into an Abstract Syntax Tree (AST)
• Semantic Analyzer: Performs semantic checks on the AST
• Symbol Table Manager: Manages symbol tables for identifier storage

Implementation Details

• Programming Language: Python
• Libraries : anytree
• Compiler Components: Lexer, Parser, Semantic Analyzer, Symbol Table Manager
• DFA : We designed the following DFA to implement the lexer.

Getting Started

To explore UniC, follow these steps:

1. Clone the repository: git clone https://github.com/SatyaSP/UniC.git
2. Navigate to the project directory: cd UniC
3. Activate the unic_venv virtual environment.
4. Run the compiler frontend using Python: python unic.py

If you are on windows you can also use unic.cmd or unic.ps1 to directly run commands on command prompt or powershell to provide the C file path. (.\unic <path/to/c/file.c>). Alternatively you can add this directory to you environment path variables list to use this command globally in your terminal.
