The Guiding Principles and New Rules document is now in effect.
So every now and again I run into RegEx's. I have no real need to learn them, except a compulsion to continue understanding the "in" things in computers, but I have discovered that they are fantastic when you need to do large scale transforms of structured text.
The problem is, I have no editor which makes this process easy. My current favorite website is this one (RegExr) which has an excellent quick reference and shows me in real time what I'm writing, so I can figure things out. It's how I've been learning so far, and I also use it for practical tasks.
Is there any free software though which will let me do something similar locally though? I'd kind of like not to be dependent on a website's continued existence to process text/test out regex's, and unfortunately, Notepad++'s support is pretty poor.
Rexexps are a unix standby and correspondingly the editors that make best use of them are *nix natives. Most have windows ports though - look into vi, emacs, and acme.
I've found "Programmer's Notepad" to be one of the best freeware text editors available, supporting a variety of languages and offering a robust regular expression engine. The only negative I've found is that it doesn't support hex expressions (e.g., [\x00-\xFF]).
Related but separate, the documentation indicates that it doesn't support multi-line expressions, but it can be done with creative use of \w,\W and \s expressions and lookaround constructs.
