var vimBinding = document.createElement('script');
vimBinding.setAttribute('src', 'https://rawgit.com/jakub-m/vim-in-textarea/master/jsvim.js');
 
 
// browser support for onload may be iffy ...
vimBinding.onload = function () {
  var vim = new VIM();

  Array.prototype.forEach.call(document.querySelectorAll('textarea'), function (instance){
      vim.attach_to(instance);
