In Python, a regular expression is denoted as RE (REs, regexes or regex pattern) are imported through re module. Python supports regular expression through libraries. In Python regular expression supports various things like Modifiers, Identifiers, and White space characters. Depending on what you're doing, you can instead use conditional compilation and MacScript to shell to Unix utilities (e.g., grep, perl) for regex handling. The goal of my regular expression is to allow me to break apart IP Table log files so that I can build a basic web front-end to allow me to view the traffic on the network. The MAC address is optional, because the way that this firewall works, is by providing the MAC address when the outbound address is not available.
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.
