How do I match a closing bracket in Emacs lisp

Question

I would think this was really simple. I am trying to match closing delimiters in Emacs Lisp regex. I can match {}()[ no problem, but I cannot match ]. I have been using re-builder and have tried "[\\}\\)\\]]", "[\\}\\)]]", "[\\}\\)\\\]]", "[\\}\\)\\\\]]"and it still won't match the closing square bracket. The brace and the parenthesis match just fine. What am I doing wrong?

Answer 1

Put the ] as the first character after the [ which starts the character class, e.g.

[])}]
