Patterns - The Regex App

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 new to regex and ready to learn, or a seasoned regex wizard looking to save valuable time, Patterns is the tool for the job. FEATURES: - Regular expression syntax highlighting makes it easy to see how your pattern is interpreted by the regex engine. No more confusion about what needs to be escaped. - The Matches view lets you inspect all matches and captured text produced by your regex, alongside your search text. Clicking on a match or group highlights both the matched search text and the specific portion of your regex that produced the match or capture. - See matches, replacements, and filter results in real time while you edit your pattern. - Use the Copy Code feature to quickly export your pattern for use in a number of different programming languages. - The built-in regular expression quick reference sheet helps you learn and expand your knowledge of regex syntax. - Customize the regex engine for different regex "flavors". Supported flavors are: Oniguruma, POSIX Basic (BRE), POSIX Extended (ERE), Perl (PCRE), emacs, Java, Ruby, bash, grep, and sed.
