rexi is a simple yet powerful CLI tool designed for developers, data scientists, and anyone interested in working with regular expressions directly from the terminal. Built with Python and leveraging the textual library, rexi offers a user-friendly terminal UI to interactively work with regular expressions.

• Interactive UI: Built on top of the textual library, providing a clean and intuitive interface to work with.
• Regex Evaluation: Supports evaluating regular expressions using either match or finditer modes, allowing users to select the most suitable method for their needs.
• Real-time Feedback: Instantly see how your regular expression patterns match or find iterations over your input, enhancing learning and debugging experiences.
• Easy to Use: Get started quickly with a simple command. rexi reads input directly from stdin, streamlining the process of testing regular expressions.

pip install rexi

cat /etc/hosts | rexi

Once the UI is open, you can:

1. Write a Regex Pattern: Enter your regex pattern in the designated input area.
2. Choose a Mode: Select either match or finditer to apply your regex pattern.
3. View Results: See the marked output based on your regex pattern and selected mode in real-time.
