Project Ideas on Haskell

Some project ideas that you can explore using Haskell, catering to different levels of experience:

 Beginner Projects

1. Calculator: Build a simple command-line calculator that can handle basic arithmetic operations. You can expand this by adding support for parentheses and operator precedence.

2. To-Do List Application: Create a console-based to-do list where users can add, remove, and view tasks. This can help you practice working with lists and user input.

3. Guess the Number Game: Implement a simple game where the user has to guess a randomly generated number within a specific range. Use Haskell's random library for number generation.

4. Text-based Adventure Game: Create a text-based game that allows users to navigate through different rooms and scenarios. This project can help you learn about state management in Haskell.

 Intermediate Projects

5. Command-Line File Manager: Develop a command-line tool to navigate directories, list files, and perform basic file operations (copy, delete, move).

6. Markdown to HTML Converter: Write a program that can parse a simple Markdown file and convert it into HTML format. This will help you understand parsing and data representation.

7. Web Scraper: Build a web scraper that extracts specific information from a website (like weather data, headlines, etc.) and outputs it in a structured format (like JSON).

8. Simple Database: Create a lightweight, file-based database system that supports basic CRUD operations. You can use CSV files for data storage initially.

 Advanced Projects

9. Functional Reactive Programming (FRP) Game: Design a small game using FRP principles. You can explore libraries like `reflex` or `reactive-banana`.

10. Web Application with Yesod: Develop a simple web application using Yesod, focusing on a RESTful API for a specific domain (like a blog, task manager, etc.).

11. Real-time Chat Application: Implement a chat application using Haskell and websockets. You can leverage libraries like `warp` and `websockets` for this.

12. Compiler or Interpreter for a Simple Language: Create a compiler or interpreter for a small programming language (like a subset of Lisp or a simple functional language).

 Research and Experimental Projects

13. Formal Verification Tool: Build a small tool that can verify properties of Haskell programs. This could involve exploring concepts from type theory or model checking.

14. Distributed System Simulation: Simulate a distributed system (like a simplified version of a peer-to-peer network) using Haskell's concurrency features.

15. Machine Learning Library: Start creating a simple machine learning library in Haskell, exploring basic algorithms like linear regression, decision trees, etc.

 Creative Projects

16. Music Generator: Create a program that generates music based on certain algorithms or styles. You can use Haskell libraries for audio synthesis.

17. Art Generator: Write code to generate visual art based on mathematical concepts or algorithms (like fractals, cellular automata, etc.).

18. Interactive Fiction Tool: Develop a platform for writing and playing interactive fiction, allowing users to create branching paths in storytelling.

 Tips for Project Development

- Start small and gradually build complexity.

- Use GitHub or other version control systems to track your progress.

- Consider writing tests to ensure code correctness.

- Engage with the Haskell community for feedback and support.

These project ideas can help you learn Haskell while also enhancing your programming skills in general. Choose a project that aligns with your interests and skill level, and have fun coding!
