Are there any good tricks to help remember RegEx? [closed]

Question

I don't always write Regular Expressions, but when I do, I feel like I'm learning it all over again. I'm looking for methods to retain the important parts, and put some method to the madness.

Answer 1

You should use the exact same trick that's used for remembering any API: use an accurate reference.

For example, when I need to work with Regular Expressions in JavaScript, I use the reference on MDN. If I need regex in PHP, I'll use the php.net reference. If I need regex in .NET, I'll use the MSDN reference.

It's better to not remember and look it up each time than it is to remember incorrectly and write it wrong.
