Emojify 😎 [10 points]

Task Overview

Create a command-line tool that encodes and decodes text messages using emojis. This task combines elements of cryptography, Unicode handling, and command-line interface design using the click library.

Objectives

1. Implement a simple substitution cipher using emojis as the cipher alphabet.
2. Create a command-line interface using click for encoding and decoding messages.
3. Handle Unicode characters correctly to support a wide range of emojis.

Requirements

• Python 3.7+
• click library
• emoji library

Install the required packages using:

pip install click emoji

Usage

Run the script with the following commands:

Encode a message:

python emojify.py encode "Your message here"

Decode a message:

python emojify.py decode "Your 😎 emoji 😊 message 😍 here"

Specifications

• The tool accepts two main commands: encode and decode.
• Encoding:
  • Input: A plain text message
  • Output: The message with each letter substituted by a unique emoji
• Decoding:
  • Input: An emoji-encoded message
  • Output: The original plain text message
• The emoji-to-letter mapping is consistent within a session but randomized between runs.
• Supports the 26 letters of the English alphabet (case-insensitive).
• Preserves spaces and punctuation in the original message.

Bonus Challenges

• Add support for numbers and special characters. [2 points]
• Create a simple GUI to encode and decode using a framework like Tkinter or PyQt [5 points]

Happy emoji-ing! 🚀
