Expressions

By Apptorium

Open the Mac App Store to buy and download apps.

Description

Expressions allows to play with regular expressions*. Just type your pattern and some text to test it. All the changes are updated while you're typing text or pattern. App highlights the syntax, so the pattern is easy-to-read and modify. If you use subexpressions (groups), you can highlight them by pressing cmd+shift+] (or [ – for decreasing the highlighted group number).
If you don't remember the regex syntax, just press cmd+r or click button in the top-right. You will get the reference sheet, so you don't have to remember everything.
The user interface is very minimalistic and non-distractive. By default the color is the same as your menubar, but you can always switch to dark or light mode (see: Preferences). You can also open app in beautiful full screen mode which is perfect when you want to focus or to demonstrate regular expressions to other people.

* Expressions uses ICU regular expression standard. More information you will find here: https://developer.apple.com/reference/foundation/nsregularexpression

Customer Reviews

Very helpful learning tool

I’m just starting to learn about regular expressions, and I’m very happy to have such a well-made native app to work with.

Great, minimial regex app

Simple and effective, with tasteful design. I’ve used web-based regex tools for years, but I was really happy to find a native one. Well done!

needs to visualize groups

I mislead myself when looking at the screenshots. I thought that the different colors were the differnt groups captured. I am always using regexes to extract a piece of info from within a larger pattern, so seeing the group color different, or explicitly listed, would make this tool more useful for me.

In the meantime, I found this instead: regex101.com
