Does anyone know of a regular expression tutorial that doesn't use a designer?
Check out Expresso I have used it in the past to build my RegEx. It is good to help learning too. Not really a tutorial but you can test out regex's with it.
RegEx Buddy, while also not a tutorial in itself, has been one of the best tools for me. The on the fly highlighting helps.
I learned the basics of RegEx with this tutorial It talks about what happens behind the scenes and doesn't depend on a certain platform.
RegexBuddy is also nice, if I may add. There is a variety of similr tools available. A simple google search "regex tool" reveals most of them. As far as for the tutorial, I can recommend the book "Mastering Regular Expressions" (I read the first, there is probably a newer edition by now)
This is a great and quick getting started guide:
The absolute bare minimum every programmer should know about regular expressions
