RegExp is a regular expression tester for developers, on Mac, iPhone and iPad. Write a pattern, paste your text, and see every match and capture group as you type, with the same engine your code uses. Six flavors, real engines: • Swift Regex • NSRegularExpression (Objective-C and Swift) • JavaScript (ECMAScript) • PCRE2, the engine of PHP • Go and Go (POSIX) Write and understand patterns: • Matches and capture groups highlighted in the test string, with their names • Errors marked right in the pattern, unbalanced brackets too • Substitution with each engine's replacement syntax, and a list mode that extracts one line per match • A quick reference of each flavor's syntax: select an item to insert it • Copy the pattern as ready-to-use Swift, Objective-C, JavaScript, Go or PHP code • Jump between matches; slow patterns time out instead of freezing the app Keep your patterns: • Sessions and folders, your own regex notebook, synced with iCloud across your devices • Search, duplicate, export and import sessions, or open one in its own window • Shortcuts actions, Spotlight search, and a Services menu item on the Mac for selected text Most of RegExp is free. RegExp Pro, a one-time purchase that works with Family Sharing, adds: • Explain: what every part of a pattern does, in plain language, and what the selected flavor doesn't support • Test cases: strings a pattern must or must not match, checked on every run • Apple Intelligence: write a pattern from a description, or get a summary of one (on supported devices) • The advanced options of every flavor RegExp speaks English, German, French, Spanish, Italian, Portuguese, Ukrainian, Russian, Japanese and Chinese.
