ParseGen CLR Compiler Toolkit

GitHub repo size GitHub contributors GitHub stars GitHub forks Instagram Follow LinkedIn Follow

Overview

This project implements a compiler for a custom programming language. The compiler consists of a lexical analyzer, syntax analyzer, and parsing table generator. Its purpose is to tokenize input source code, check for syntactic correctness, and generate CLR parsing tables.

Project Structure

  • main.py: Main program that coordinates lexical analysis, syntax analysis, and parsing table generation.
  • lexer.py: Contains functions for tokenizing input source code.
  • parser.py: Implements syntax analysis and LR(1) parsing table generation.
  • program.txt: Input source code to be processed by the compiler.
  • grammar.txt: Context-free grammar rules for the programming language.
  • README.md: Project documentation.

Components

  1. Lexical Analyzer: Identifies tokens in the source code and removes whitespace and comments.
  2. Syntax Analyzer: Parses the tokenized input according to grammar rules and checks for syntactic correctness.
  3. Parsing Table Generator: Constructs CLR parsing tables based on the given context-free grammar.

Usage

  1. Clone the repository:

    git clone git@github.com:Priyanshuparth/ParseGen-CLR-Compiler-Toolkit.git

  2. Navigate to the project directory:

    cd Compiler-Design-CLR

  3. Run the main program:

    python main.py

  4. Provide the input source code (program.txt) and grammar rules (grammar.txt).

Example Usage

Here's an example of how to use the compiler:

  • Provide the input source code (program.txt) and grammar rules (grammar.txt).
  • Run the main program (main.py) to tokenize and parse the input code.
  • View the generated parsing table and parsing actions to identify any syntactic errors in the input code.
