JSDoc 3 parse error getter/setter with the same name in strict mode

Question

I am getting error when compiling the following code to generate a document with JSDoc 3. If I remove the first line, "user strict";, then it works. Is this a bug in JSDoc, or I am missing something?

Code:

"use strict";

var BaseClass = require("./BaseClass").BaseClass;

/**
 * @class
 * @extends BaseClass
  */
 var MyClass = BaseClass.extend(
 /** @lends MyClass.prototype */
 {
     /**
      * Initializer.
      * @public
      */
     initialize:function () {
         this._id = -1;
     },

     /**
      * Property id
      * @public
      * @property {number} id
      */
     get id() {
         return this._id;
     },

     set id(id) {
         this._id = id;
     }
 }); 

 exports.MyClass = MyClass;

Here's the error I am seeing:

./jsdoc3/jsdoc -c ./conf.json

Answer 1

As noted above, this syntax is legal in JavaScript's strict mode. I suspect this is a parser bug in the version of Mozilla Rhino that JSDoc uses.

As a workaround, you can use the following plugin to comment out the "use strict" declaration before JSDoc parses the file:

exports.handlers = {
    beforeParse: function(e) {
        e.source = e.source.replace(/['"]use strict['"]/g, "//'use strict'");
    }
};
