Error: Unexpected end of input

[robtarr]

I have a project that i Just started a couple of months ago, and set up jsdox. I just made some changes, and recently upgraded to Node 4.3.1 (not sure if that is causing the problem). But when I try to run jsdox now, I get:

Error generating docs for file featurama-client.js [SyntaxError: Unexpected end of input]

    at Socket.emit (events.js:169:7)
    at Pipe._onclose (net.js:469:12)

This is the file I'm running it on is this:

module.exports = function() {
  var list = {};

  /**
   *  Enable the indicated feature
   *
   *  @param    {String} featureName
   */
  function on(featureName) {
    list[featureName] = true;
  }

  /**
   *  Disable the indicated feature
   *
   *  @param    {String} featureName
   */
  function off(featureName) {
    list[featureName] = false;
  }

  /**
   *  Return the on/off status of the indicated feature
   *
   *  @param    {String} featureName
   */
  function enabled(featureName) {
    return list[featureName];
  }

  return {
    init: _buildList,
    on: on,
    off: off,
    enabled: enabled
  };
}();

It seems like deleting any line of code from this snippet (I've already ripped out some) fixes the problem. This, however, is not a very good solution. :)

I've traced it back to line 17 of jsdoc3-parser, and I've tried to play with the maxBuffer size, but have not had any luck.
execFile(cmd, ['-X', filename], { maxBuffer: 5120 * 1024 }, jsdocParser._onComplete.bind(null, cb));

Thanks for filing the issue. Here are a few questions that might help
troubleshoot the issue:

• Does it work with a previous node version?
• Does it work with a newer node version?
• Can you revert your file changes and test?

It doesn't seem like a library issue at first glance.

• It does work in 0.12
• It does not work in 4.3.1 or 5.7.0
• It does not work with the reverted changes

Would love any insight into this. Is anybody else using this with 4.3.1?

Thanks for the info! We should add those node versions to the travis config
to see what fails.

I ran jsdox on the code provided in the first comment on this thread, but did not get any errors (using node 5.9.0).

As the build is working fine on Travis, I suspect there may be some encoding issues with your original file. And as just removing lines randomly also helps, it may be just that re-saving fixes the encoding.
