RegEx Knife version 1.0.5 is available in the App Store. This version fixes a crashing bug that occurs when working with Regular Expressions containing 10 or more capture groups.
RegEx Knife has had 622 downloads so far (~60/month) – still hardly a rush. Clearly the iPad isn’t the best place to be doing RegEx development, but its handy when you need it.
I have several large text files (>1MB each) that I regularly need to search (no pun intended) for specific quotes. I’ve longed for a good regex editor (use BBEdit on my Mac) to use on the iPad, and also a good way to develop, test, store, and re-use particular patterns. Regex Knife has filled the bill for the latter purpose, and I’m so happy to have found it. Recognize your name from Script Debugger, which I’ve used for forever…I’m still testing out various text editors to see which I like.
