Patterns - The Regex App App Reviews

I think it does what it should, and for me it was all pretty self-explanatory. Well made simple app for quickly testing regex syntax. It doesnt have a specific Javascript mode, but for me it has worked to use it in Ruby mode so far when building syntax for javascript, Im not sure if they differ.

Just what I needed! I never created a regex that easily :)

Im kind of annoyed by the escaping bugs I get when exporting to different formats, as specially PHP. I dont like to always double check my regex on copy-paste. I mean, whats the point when I already tested it in Patterns. My suggestion would be to use instead of " for the string encapsulation and make sure everything inside is escaped as should be !

And the regex matching is not always correct either

Small but very useful App, that every Developer should have in his tool box!

Thansk for updating with Sierra support. If you need to fiddle with RegExp this is the best tool out there hands down.

Works great and saves so much time when writing regular expressions.

Its a very decent app, the fact that you can use different technologies to perform the regex is priceless. However it currently has a very annoying bug where it scrolls to the bottom of the search text whenever you modify the regular expression. If you have to scroll at all (I prefer you keep my scroll position) then scroll to the top. Not a serious bug, but still frustrating. Other than that, awesome app and infinitely useful if you use regexes on a weekly basis.

Nice app so far, however the help screen scrolls at an excessively slow rate when using the two finger trackpad scroll. Not consistent with OS settings that apply to scrolling in other apps. (On Macbook Pro, OSX Lion 10.7.2) Also, it would be nice to be able to have multiple windows open at a time, to be able to try different regex options without losing your work on the first one. Would rate 5 stars if these features were fixed/added.

Overall really great app. I would like to see an overhaul of the reference sheet. Perhaps have an index on the side for easy access to different groups.

I cant give much of a review as to the performance of this app, because by limiting the amount of space that you have to enter your regex, theyve basically made this app pointless to me. Such potential, wasted for no real reason. I guess Ill keep looking.

Excellent app for developers, but the help section needs some improvement.

This app is good for previewing regex matches and replacements, but its kind of useless because it cant do batch file regex match and replacements.

This app is simply invaluable for quickly testing and composing regular expressions, and seeing results interactively. It works very well, and has saved me so much time by not making me run scripts over and over to test. This app easily pays for itself in one use! I would like to see the rows in the search/replace lined up, so if you scroll one the other scrolls too, to keep them in line. Also, might be nice to see the matches $1/$2 and such color-coded in the search column so you can see whats being matched.

This app has already proven itself very useful when I need a quick way of checking whether my regex is actually matching the text I think its matching. For that alone, its worth the price. The reference sheet is also very useful. My only suggestion for an improvement would be providing support for complete regexes - ie, if I select Perl as the language, I should be able to evaluate s/^[Ff]o.+/Bar/ and see the output. As it is, entering ^[Ff]o.+ will show me what text is matched, and I can provide replacement text in the "Replace" panel, but I cant construct the full regex that Id use in a Perl script. Otherwise, this is a fantastic app, and well worth it to anyone who finds themselves dealing with regexes just often enough that they dont always remember the right syntax.

I thought this would be a mild time saver (Im reasonably good at building expressions anyway) and simply "worth the money" when building something very complex. But in just the past few days its become the place I *start* for every batch of text I need to process. The live preview makes far more difference than I had anticipated and my old methods seem painfully slow by comparison. It is now essential to my workflow. Developer: How about adding a Service: "Send selection to Patterns" to help move text around? THANKS!

Works very well to test regexes. The built-in cheat sheet is clear and effective. Regex highlighting is also very useful to ensure you got the correct syntax. Overall a very nice little tool for developers! Highly recommended for anyone who has to work with regexes.

This is really a nice app, light and efficient. What would make me give it 5 stars would be to be able to see the matched patters in parentheses ($1, $2, etc.). This feature is missing in version 1.0.1.

When I need to write a regex Patterns is my app of choice. Simple to use. Really like the Regex Cheatsheet that it includes. Saves me time looking for codes each time. Definitely worth the $3.

Just as CodeRunner, Patterns is great tool that will help you to get things done without creating disposable projets or scripts. The code generator allows you to focus of the already-hard-enough task : writting a regular expression. Totally worth the money.
