is_file_in

is_file_in / isFileIn

A function(filename, specs) thats checks if 'someFile.ext' passes through an of Array of minimatch / RegExp / callbacks specs, with inclusion OR negation/exclusion '!' flag

The Array of filename specifications (or simply filenames), can expressed in either:

• String in gruntjs's-like expand minimatch format (eg '**/*.coffee') and its exclusion cousin (eg '!**/DRAFT*.*')

• RegExps that matches filenames (eg /./) again with a

[..., '!', /regexp/, ...]

negation / exclusion pattern.

• A function(filename){} callback, returning true if filename is to be matched. Consistently it can have a negation / exclusion flag before it:

[..., '!', function(f){ return f === 'excludeMe.js' }, ...]
```.

  Note the trap: use a `true` (i.e matched) as the function result, preceded by '!' for **exclusion**. The common trap is to return a `false` for your *excluded matches* and then all your non-excluded with match with `true`, which is probably not what you want!.

* @todo: NOT IMPLEMENTED: An `Array<String|RegExp|Function|Array>, recursive, i.e

[ ..., ['AllowMe*.*', '!', function(f){ return f === 'excludeMe.js' }, [.., []], ...], ...]

# Examples

```javascript

var specs = [
 '**/recources/*',
 '!badFile.json',
 /.*\.someExtension$/i, '!',
 /.*\.excludeExtension$/i,
 function(fn) { return fn === 'includedFile.ext' },
 '!', function(fn) { return _.startsWith('DRAFT') }
];

isFileIn('someFile.someExtension', specs) // true

isFileIn('someFile.otherExtension', specs) // false

isFileIn('includedFile.ext', specs) //true

isFileIn('DRAFTFile.ext', specs) // false

See the specs for more examples.
