RegEx Knife version 1.0.4 is available in the App Store. This version fixes bugs that escaped my notice when developing RegEx Knife 1.0.3.
I see Script Debugger as a tool that makes professional developers money by saving them a lot of time. Those that really need Script Debugger know it and would pay much more because of this simple equation. In fact, if I had more courage I would raise the price even further.
As a followup to my Getting Yosemite AppleScript Progress Information post I would like to offer this PSA.
Development on Script Debugger 1.0 started in 1993. Version 1.0 was released in late 1994 and was introduced publicly at MacWorld in San Francisco in January 1995.
