Too basic (only ICU, no flags support, no substitutions). Frozen after 2 clicks. Sorry, not useful

I love this app - have been using RE's for decades but this really help getting them right quickly rather than laboring over them.

There doesn’t seem to be a way to test and preview regex substitutions in this app. If that is the case, then it’s as good as useless for any serious regex testing. If I’m wrong, I’ll change or delete this review.

Very limited functionality. regex101.com and regex.ai are much more useful.

Freezes often. Can’t open panes. Removing this until a new version comes out.

Friert nach wenigen Sekunden ein. Bekomme nicht einmal Text eingetippt. Ein Klick auf einen Button offenbarte dann das doch etwas ankam. Dafür fror es dann mal wieder ein.

Only supports the ICU regex standard - not PCRE, POSIX...

i couldn't find a way how to use flags. also it doesn't recognize delimeters to eventually ignore them. at the end of the day basic regexp101 has more rich functionality

It’s certainly not the fullest-feature RegExp application out there, and the UI could definitely be improved*, but I nonetheless have found both the reference and the ability to step through group captures useful, so it is still a welcome addition to the developer tools in SetApp. * Why are there no buttons for next and previous group on the main window? Why do the side panels default to closed on first open? Why are case sensitivity, allowing comments, and other options global rather than set on a per-RegExp basis? RegExp language variants?

It is just unusable and the UI/UX is so bad that I don’t know what to do when I open the app

Very limited (compared to well known websites), freezes all the time, not useful.

I wanted to learn Regular Expressions to conduct complex searches for document editing and filing. I had never used Regex before and Expressions made it relatively easy to learn and develop the searches I needed. I will not need it very often as once I ave developed search criteria I save them. Nevertheless, it is reassuring to have Expressions to create new ones in the future.
