[Vimperator]semiAutoComplete （テキトウにコードを書いていたらタブを押して初めて自動補完が有効になるコードとなった

semiAutoComplete.js

let (cl = commandline) {
  cl._autocompleteTimer = new Timer(200, 500, function autocompleteTell(tabPressed) {
    if (events.feedingKeys || !options["autocomplete"])
      return;

    if (!this._completions && this._commandWidget.value.length >= 2) {
      this._completions = CommandLine.Completions(this._commandWidget.inputField);
      this._completions.complete(false, false);
    }

    let ctx = this._completions.context;
    let argsContext = ctx.contexts["/ex/args"];
    if (argsContext && argsContext.filter.length >= 3) {
      this._completions.complete(true, false);
      this._completions.itemList.show();
      return;
    }
    //this.resetCompletions();
    //this._completions = null;
    this._completionList.hide();
  }.bind(cl));
