Does Emacs provide a shorter way of matching an emacs-lisp symbol
(identifier) than the following:
"\\(" "\\(?:" "\\w\\|\\s_" "\\)+" "\\)"
Thanks in advance,
Nordlöw

You mean the concatenation of those strings? (BTW, if you want to make
it easier to read then rx is an alternative.)
You do not need two level of parenthesis. Use either the shy group or
the submatch group type parenthesis.

He needs two if he wants to match the entire symbol in a matching group,
though.

Yes, my bad.

I don't think so. In fact, you should also add \\_< and \\_>, so it
doesn't match half symbols.
