Joshua Coppersmith “RegexBuddy is to regex what the pocket calculator was to arithmetic. And the painstaking improvements in ‘flavors’ is admirable.” 18 September 2013, Kansas, USA—later: “This is one of those very rare programs that makes me laugh—a different sort of laugh, that shake your head and grin laugh—for the mysterious reason that is a combination of intrigue for the subject and respect for those articulating it. Having studied Jeffrey’s book I thought, “Ok, now…gasp…it’s time to start using all this.” But with RegexBuddy I have basically no fear. Oddly, not because the program “does it for me,” (even with RegexMagic) but because I can co-discover with the program what I’m trying to say “in Regex.” Thus, I play, I learn. I need a regex for a meta function on a website, I learn. It is to regex what the best language learning courses are to natural language. “I guess I gotta say using this is something of a thrill. And for my part, much safer than roller coasters.” 2 November 2013, Kansas, USA

Daniel Marohn “My done code so far can be clearly divided into pre and post RegexBuddy times. I knew all about regexes before and used them if needed, but without RegexBuddy, debugging took longer than writing code. After buying RegexBuddy I use regexes wherever useful, reduce code and finally have time for real business logic.” 7 February 2008, Germany—5 years later: “I bought RegexBuddy 5 years ago. I think there are less than 30 working days than since, that I did not use it. I got all the free updates/bugfixes over the years and finally asked myself: WHY? I was more than willing to pay for updates after two years or so but it was always free. This is really fair and best practice for consumer satisfaction. “As a coder I know that a software is never ‘finished’. But I always thought that regexbuddy 3 is as closed as possible to this state. When I got your mail about version 4 I was surprised. You really managed to add THIS lot of valuable things under the hood; leaving the interface intact—I am really impressed. Coding is one thing, concurrently knowing about UX a complete other.” 1 August 2013, Germany
