I bought this application based on the love affair I have with CodeRunner, but this one just misses the perfect mark. Seems like some of the valid regex Ive thrown into it dont validate and when copying code out of it in php code, it uses double quotes and escaped slashes which really nag my work flow since theyre not pretty and not efficient. The issues ive had with code runner are with character classes and utf-8 testing using p{L} type checks which never seem to validate. I want to love this app, and over time perhaps those features will also be added in, but right now its not the be all end all of regex testing, and in fact, i could probably do more with CodeRunner considering it ties into the libraries installed on my machine.
Great for testing smaller simple regex, but doesnt quite pass muster when pitted against unicode.
