Text Converter Flow

This project demonstrates an interactive text transformation tool built with PocketFlow.

Features

• Convert text to UPPERCASE
• Convert text to lowercase
• Reverse text
• Remove extra spaces
• Interactive command-line interface
• Continuous flow with option to process multiple texts

Getting Started

1. Install the required dependencies:

pip install -r requirements.txt

2. Run the application:

python main.py

How It Works

The workflow features an interactive loop with branching paths:

graph TD
    Input[TextInput Node] -->|transform| Transform[TextTransform Node]
    Transform -->|input| Input
    Transform -->|exit| End[End]
    Input -->|exit| End

Here's what each part does:

1. TextInput Node: Collects text input and handles menu choices
2. TextTransform Node: Applies the selected transformation to the text

Example Output
