CodeMirror: Closebrackets Demo

Type a bracket like '[', '(', '{', '"', or ''' and the addon will auto-close it. Type the closing variant when directly in front of a matching character and it will overwrite it.

If you backspace over a starting bracket while inside empty brackets (e.g. {|}), it will delete the closing bracket for you.

(function() {
  var DEFAULT_BRACKETS = "()[]{}''\"\"";

CodeMirror.defineOption("autoCloseBrackets", false, function(cm, val, old) {
    var wasOn = old && old != CodeMirror.Init;
    if (val && !wasOn)
      cm.addKeyMap(buildKeymap(typeof val == "string" ? val : DEFAULT_BRACKETS));
    else if (!val && wasOn)
      cm.removeKeyMap("autoCloseBrackets");
  });
