Ha, this app is great. The funny thing is that I just wrote the same kind of app (free) for PERL testing. I was getting tired of typing into terminal, and more importantly, I was tired of trying to format multi-line code in the terminal (it's just so hard to read). I went ahead and got it; it's only a buck, and it does just what it says it does. I had been relying on dreamweaver to edit my code - which works, but you have to keep uploading it to a server to test your code, which is time consuming.
