Compiler

A Python-based compiler project implementing a lexer and parser for a custom language, using PLY (Python Lex-Yacc). This project demonstrates how to write a full-featured lexer and parser capable of handling declarations, function definitions, control statements, and more.

Features

  • Lexical analysis and parsing for a C-like custom language
  • Handles variables, functions, types, control flows (if, else, for, etc.), and more
  • Based on PLY (Python Lex-Yacc)

Prerequisites

  • Python 3.6+
    Make sure Python is installed and available in your environment.

  • PLY package
    Install PLY via pip:

    pip install ply

Installation

Windows

  1. Clone the repository:

    git clone https://github.com/HoomanMoradnia/Compiler.git
cd Compiler

  2. Install dependencies:

    pip install ply

  3. Run the compiler:

    python Compiler.py

    You can modify the test input at the bottom of Compiler.py or adjust it to take input from a file.

Linux

  1. Clone the repository:

    git clone https://github.com/HoomanMoradnia/Compiler.git
cd Compiler

  2. Install dependencies:

    pip3 install ply

  3. Run the compiler:

    python3 Compiler.py

    You can modify the test input at the bottom of Compiler.py or redirect input as needed.

Usage

  • The main file is Compiler.py. It contains both the lexer and parser logic.
  • By default, running the script will process sample code defined in the if __name__ == "__main__": block at the end of Compiler.py.
  • To parse your own code, you can replace the test_input variable in the script or refactor the file to accept external input.
