Thanks for the link! I tried it. What I like better about Regex Buddy is subtle. I dislike having to keep clicking on Match Expression in Regex Designer.
Also, probably the biggest thing Regex Buddy has going for it, is the example where someone provides you a regex that does exactly what you need, but it looks like gibberish, there is a mode that explains what each token means to try and help you understand what is going on.
The Linux tool, Regex Coach that I mentioned in the original article is less useful, as it does not even have an easy way to insert a token by english name, instead of knowing it in advance.
