Patterns is the ultimate tool for working with regular expressions. Build great patterns quickly and effortlessly with regex syntax highlighting, live match view, replace mode, built-in quick reference, and much more. Whether you're a seasoned regex wizard or new to regex, Patterns is the only tool you'll ever need. FEATURES: - Regular expression syntax highlighting makes it easy to see how your pattern is interpreted by the regex engine.
