What is Regex Assistant?
The Regex Assistant is a specialized tool designed for the Openclaw Skills library to simplify the often-complex world of regular expressions. It serves as a dedicated testing and debugging environment, allowing developers to verify pattern accuracy, inspect capture groups, and preview text transformations in real-time.
By leveraging this skill, users can automate data validation and text processing workflows with high precision. Whether you are a seasoned developer or just starting with pattern matching, this tool within the Openclaw Skills collection provides the necessary transparency to debug regex logic efficiently.
Regex Assistant Use Cases
- Validating user input formats such as emails, phone numbers, and identity cards.
- Extracting specific data points from unstructured logs or large text files.
- Performing batch text cleaning and formatting via regex-based replacement.
- Debugging complex capture groups and non-greedy matching behavior.
- Rapidly generating standard regex patterns for common development tasks.
How Regex Assistant Works
- The user provides a specific command (match, findall, groups, sub, or pattern) along with the regex pattern and target text.
- The skill processes the request using a Python-based engine with full Unicode support.
- The tool evaluates the pattern against the text, identifying matches or executing replacements as defined.
- Detailed results, including match positions and group contents, are returned via the CLI for immediate verification.
Regex Assistant Setup
To use this tool from the Openclaw Skills repository, ensure you have Python 3 installed and follow these steps:
# Navigate to the regex-assistant directory
cd regex-assistant
# Test a pattern match for an email address
python3 script/main.py match "[\w.+-]+@[\w-]+\.[\w.-]+" "[email protected]"
