I see this line of code and the regular expression just panics me…
quickExpr = /^(?:[^#<]*(<[\w\W]+>)[^>]*$|#([\w\-]*)$)/
Can someone please explain little by little what it does?
Thanks,G
Here’s what I can extract:
^beginning of string.(?:non-matching group.[^#<]*any number of consecutive characters that aren’t#or<.(<[\w\W]+>)a group that matches strings like<anything_goes_here>.[^>]*any number of characters in sequence that aren’t a>.The part after the
|denotes a second regex to try if the first one fails. That one is#([\w\-]*):#matches the#character. Not that complex.([\w\-]*)is a group that matches any number of word characters or dashes. BasicallyThings-of-this-form$marks the end of the regex.I’m no regex pro, so please correct me if I am wrong.
