RegEx Knife

By Mark Alldritt

This app is only available on the App Store for iOS devices.


RegEx Knife is an easy and useful tool for working with Regular Expressions.  RegEx Knife is unique in how it allows you to highlight capture groups within a Regular Expression, edit them and immediately see the results. RegEx Knife also makes it easy to experiment with regular expression substitutions.

Version 2 retains the simplicity of the original RegEx Knife, with the added advantage that it works on your iPhone as well as your iPad.

New Features in RegEx Knife 2.0:

- Runs on all iOS devices from iPhones to the 12" iPad Pro.
- iOS multi-tasking and split-view support.
- Spotlight searching finds expression names and expression content.
- Reorganized UI makes regular expression options more accessible and makes it easier to work with long bodies of sample text.

Im using iPhone8plus 256 model-

This app is very nice, but im not move to LunchViewController->MainVC

Great Tool

As the saying goes "does what it says on the tin". I code for work and manipulate vast amounts of information, this tool is fantastic for quickly testing expressions against a data set which is easily manipulated. Has saved me untold time trying to sort out the correct expression.
