A couple of issues with JSHint: 'is defined but never used' and 'is not defined'

Question

I have this application pretty modular and as such, JSHint is giving me the 'x' is defined but never used error.

My setup goes like this:

app/assets/scripts/bootstrap.js: var x = 5;

app/assets/scripts/kickstart.js: console.log(x);

And here's the output I get from JSHint:

app/assets/scripts/bootstrap.js
  line 1  col 6   'x' is defined but never used.

app/assets/scripts/kickstart.js
  line 1  col 13  'x' is not defined.

2 problems

I know I could us something like /* exported x */ but would be really cumbersome if I have lots of variables like this.

Is there anyway to solve these 2 issues without disabling their specific options? Because they could come in handy in other, more important, situations.

You can add this at the top of the file.

/*jshint unused: false, undef:false */

Notice that options can be applied to specific scopes. This works for unused, but apparently not for undef.

(function () {
  /*jshint unused: false */

  // Stuff
}());

`Is there anyway to solve these 2 issues without disabling their specific options` - This is from the question :) – thefourtheye Mar 20 '14 at 03:41
@thefourtheye That's why I've added the part about scope options. – sabof Mar 20 '14 at 03:42
That doesn't really help much, I would have to add a similar comment to a bunch of files. That's what I want to avoid. – rfgamaral Mar 20 '14 at 03:51
@RicardoAmaral You can also have a JSON configuration file in a folder. In that case the options will be applied to all files in that folder – sabof Mar 20 '14 at 03:53
Won't that apply a global configuration to the folder? – rfgamaral Mar 20 '14 at 03:57
@RicardoAmaral Yes. But you can have several folders. – sabof Mar 20 '14 at 04:02

I'm not going to restructure my folder structure to work around an issue like this, that's bad design and it means something is broken. – rfgamaral Mar 20 '14 at 09:42
