code: function(abbr, syntax) {
  			var snippet = this.expand(abbr, null, syntax);
  			if (snippet === null) {
  				return null;
  			}
  
  			if (Array.isArray(snippet)) {
  				return snippet.join('\n');
  			}
  			
  			if (typeof snippet !== 'string') {
  				return snippet.data;
  			}
  			
  			return snippet + '';
  		}
docs: Same as <code>expand</code> method but transforms output into
  Emmet snippet
  @param {String} abbr
  @param {String} syntax
  @returns {String}
