Get list of files using synchronous globbing

deglob.js

// problem: the order of the files it finds can be different each time glob searches the exact same path
// solution: use synchronous globbing instead

var _ = require('lodash'),
    glob = require('glob')
;

function deglob() {
    var syncGlob = glob.sync,
        patterns = _.flatten(arguments, true);

    return _.flatten(patterns.map(function (pattern) {
        return syncGlob(pattern).map(function (file) {
            return pattern.charAt(0) === '!' ? ('!' + file) : file;
        });
    }), true);
}

var files = deglob(
    ['scripts/app/**.js'],
    ['scripts/lib/**.js']
);

// `files` will now be an expanded list of individual files that's in the exact same order every time
