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.
• If you have a syntax error in your pattern, a helpful error message lets you know the exact nature of the error.
