Regex Helper

This skill tests regex patterns against input text and returns all matches.

Examples

• "Test the regex \d+ against 'I have 42 cats and 7 dogs'"
• "Find all email addresses in this text: ..."
• "Does 'hello-world_123' match ^[a-z-_0-9]+$ ?"

Instructions

Call the run_js tool with the following exact parameters:

• script name: index.html
• data: A JSON string with the following fields:
  • pattern: the regex pattern (without delimiters, e.g., "\d+")
  • text: the text to test against
  • flags: (optional) regex flags like "gi" for global case-insensitive. Default is "g".
