RegExRX App Reviews

I was looking for something that would let me replace text over and over again with regular Expressions. This has the cleanest interface of all regular expression editors I’ve tried, even the online ones. I was able to save so much time by using this, it all just felt natural. If you are looking for something powerful to help you with any regular expression endeaveor, this is exactly whatyou need.

Tried some of the other app store regex tools and this one is the best I’ve found...

good and useful application but what a pity that its so unstable ! … crash so often and if we dont save our work often, we can loose a lot of time in doing again and again the same things because suddenly it crashes and we didnt save ... please, an update to fix these too many crashes !!!

Im using the REGEX for many years and this tool is the best I never used. I regret not having found the time to do it ;-) I recommend it for all, and particularly to the 4D developers (its my job) as a great help. The live matching against source text allow to build the regex quietly. More, you can copy the pattern with compatible escaped characters with the code editor of 4D. Bravo

Thats the best tool of its kind that I came across for Mac OS X. My only suggestion is to add a reference card, because sometimes its better to have everything in one place rather than having to search for what you want in a bunch of menus.

Really simple and efficient. Easy to use, very powerful but still simple. I do recommend.

I wish I had bought this app sooner - its not just that it makes working with regular expressions much easier (as you see the result immediately), it also leads me to have much better regular expressions than I would normally manage (by making all the options easily accessible (see screenshot 2 above) - Im currently going over all my old RegEx patterns and find that I can improve nearly all of them! Really really well done, Ken.

Awesome little helper although i like patterns UI a bit more. But anyway this is certainly the best regex application in the App Store as subgroups are easily visible and compared to oyster this app actually works xD

Highlighting of the matches is great, multiline support works very good. But some improvments could improve the workflow very much: 1) Provide a RegEx documentation and a Quickreferens for that 2) Provide a „Copy to Clippboard“ Button with all selectable languages 3) Provide Shortcuts for „Copy to Clippboard“ with the favorite(s) languages (like cmd+1 or something) 4) auto expansion of $-variables in the matched list

Pretty neat tool which helped me a lot optimizing my String-Operations. Would not miss this little app anymore. Great work!

lacks in places, most noteably the inability to have any whitespace, or comments in your regex, makes working with really big regexes unnecessarily difficult. Still, best of its kind I could find on the app store.

By far the best Regex app in the App Store. Only think it lacks is the UI isnt the most beautiful.

Ive been looking for a new tester since my old go-to apps no longer work. I figured that I would give this a shot. The app works, but as I mentioned in the title, it looks horrible on retina displays. Would rate higher given a UI cleanup.

I like how you can view the values of hidden characters by moving the curser over text. I also like how it dynamically shows what gets matched as you type out the regular expression pattern. Also love how it shows the groups in a drop down so you know that you captured what you wanted to.

I love that I can check out my regexps dynamically, before stuffing them into a Perl script or a BBEdit macro. Unlike some of the reviewers, I do not find the GUI to be a problem. But then, Im used to writing sed(1) scripts on the Unix command line, so ANYTHING is a vast improvement!

This App proved very useful. Highly recommended! Its great for learning and developing regular expressions. I was using the App as text processing utility instead of its intended purpose as a development tool -- as such Id like to see an option added to "Save" and "Save As…" for the replaced text. As it is right now you have to load the source text from one fiile then copy and paste the replaced text into a text editor such as BBEdit. That got a little tedious as I needed to do nearly a dozen different replacements on the file. So switching back and forth between this App and BBEdit and remembering to save the changes in BBEdit each time and then correspondingly switch back to this App and reload the modified file so I could process the next expression got a little repetitious and if I ever forgot to reload the changed file then I would lose the previous changes on the following repetition. Even as is this App saved me a ton of time. Thanks!

Ive tried, I think, four different interactive regex tools prior to this one and, from my first half hour with it, this will become my go-to version. For those who havent ever used a tool like this, being able to create some sample text containing all the variants that your regular expression must match and then to build a search pattern step-by-step while verifying immediately that it is matching correctly and teasing out exactly the capture groups you need is much, much more efficient than trying to do the same sort of verification in-place in the code using normal code debugging tools. Several of the earlier tools Ive tried were very good but always seemed to lack some component that kept them from being great. This app seems to have pretty much everything Im looking for: a clear interface with simple text boxes for the search pattern, source text and match list; a clear, pop-up list of the various pattern components, sensibly grouped, color coding of the pattern to make review easier, and (very important for me) the best display Ive seen yet of all matches and (in a collapsible list), all captured groups within each match. The only expected feature that I didnt find, and not a biggie, is that the app doesnt show the name of named capture groups in the Match List display, just the match number. This would only matter in very complex patterns but it should be easy for them to add. Highly recommended.

Regular expressions are challenging, but a good one is like magic. A bad one can be bizarre beyond belief. The examples that come with this application are a great help in getting powerful features embedded in your code, or just in parsing text files. An incredibly good deal and if you are at all interested in regexes (sp?) you need this application. It is quick, well thought out, has a clean interface and lots of useful options.

Regular Expressions are complex and one little change can totally ruin your results. This app and the free samples make it easy for a novice to get the results they need and powerful enough for an expert to test extremely complicated expressions. Thanks for making the app and thanks for making it a real bargain.

Ive only been using it for a couple of weeks but Ive found it very useful and intuitive. Works as advertised.
