Example of easy linting of sprites from sprity-js

SpriteLinter.js

var gutil = require('gulp-util');

module.exports = () => {
    var Sprite = require('./Sprite.js');
    for (var folderName in Sprite) {
        var folder = Sprite[folderName];
        for (var imageName in folder) {
            var image = folder[imageName];
            var hoverImage = folder[imageName + 'Hover'];
            var activeImage = folder[imageName + 'Active'];
            if (hoverImage) {
                if (hoverImage.width != image.width ||
                    hoverImage.height != image.height) {
                    gutil.log(gutil.colors.yellow("[Sprite]"), gutil.colors.red.underline(imageName));
                    gutil.log('Dimensions: ' + image.width + ' x ' + image.height);
                    gutil.log(gutil.colors.green('Hover Dimensions:'), hoverImage.width + ' x ' + hoverImage.height);
                }
            }

            if (activeImage) {
                if (activeImage.width != image.width ||
                    activeImage.height != image.height) {
