Exporting the depcheck ‘special’ property so it can be used in the op…

[edj-boston]

I added a special property to the gulp plugin that is a duplicate of the depcheck dependency inside the plugin itself. It allows you to bring in special parsers and pass them as options, like so:

var gulpDepcheck = require('gulp-depcheck');

gulp.task('package', gulpDepcheck({
    ignoreMatches : [ 'bootstrap',  'jquery' ],
    specials : [
        gulpDepcheck.special.babel,
        gulpDepcheck.special['gulp-load-plugins']
    ]
}));

Notes:
1.) If someone passes their own version of depcheck as an option, it will not be used by the special property. But they can pass their own specials in like so:

var depcheck = require('depcheck');
var gulpDepcheck = require('gulp-depcheck');

gulp.task('package', gulpDepcheck({
    depcheck : depcheck,
    ignoreMatches : [ 'bootstrap',  'jquery' ],
    specials : [
        depcheck.special.babel,
        depcheck.special['gulp-load-plugins']
    ]
}));

2.) I could not get your code to build on my machine:

[16:14:38] Starting '_license'...
[
  {
    package: 'has',
    version: '1.0.1',
    license: 'UNKNOWN'
  }
]
[16:14:39] '_license' errored after 112 ms

But it did lint at least.

Thank you so much for sending a PR! It looks great, there are only a few really minor issues that I would like to ask you to address (see comments).

Apart from that, if you want to, would you mind adding yourself as a contributor to the package.json file? Once these things are done, I am happily going to merge this 😊

Can you please change this to indentation with two spaces instead of four?

[edj-boston]

Done.

Can you please change this to indentation with two spaces instead of four?

[edj-boston]

Done.

[goloroden]

Can you please remove the second const, indent the line with six spaces, and add a comma to the end of the first line?

[edj-boston]

Done.

[goloroden]

Can you please rename dc to depcheck, and also change the subsequent ones?

[edj-boston]

There will be a variable naming conflict between the global depcheck and the const depcheck within the gulpDepcheck scope. Do you have a different preferred name, or another workaround?

Ah, okay, I see… hmmm. What do you think about this one:

• The global one is depcheck, as it represents the module.
• The local one could be called depcheckInstance, as this now is the specific one you are going to deal with.

What do you think?

[edj-boston]

Makes sense! Fixed.
