function make(style, value, defaultValue, editorDidMount, onChange, options, children) {
  return ReasonReact.wrapJsForReason(ReactCodemirror2.Controlled, {
              style: Js_undefined.fromOption(style),
              value: Js_undefined.fromOption(value),
              defaultValue: Js_undefined.fromOption(defaultValue),
              editorDidMount: Js_undefined.fromOption(editorDidMount),
              onBeforeChange: Rebase.Option[/* mapOr */18]((function (f, _, _$1, value) {
                      return Curry._1(f, value);
                    }), (function (_, _$1, _$2) {
                      return /* () */0;
                    }), onChange),
              options: Js_undefined.fromOption(options)
            }, children);
