Probably needs an update
This app has been useful, but recently I can’t exit from a custom RegEx back to the main menu. I’m guessing the app needs to be updated. Otherwise I’d give this a much higher star rating.
Hands down the best
I couldn’t find it in the AppStore sometime ago. Thanks for RegEx Knife.
Please support Chinese.
When there are Chinese characters in the regular expression, they will not be displayed.
Tool for what?
Developer should integrate this into shortcuts where it will actually be useful for different types of extractions and maybe a different more up to date UI
Works for basic regexes and that’s it
It’s nice for simple regexes. Unfortunately, I wanted to use a conditional substitution, but the syntax for that varies by engine and the app doesn’t specify what uses. Would be 5 stars otherwise.
