A way detect task end

[froboy]

I think I might have found a solution to this... I'm using a promise to check to see that preview.html exists, which is the last item that Grunticon writes to the destination directory, then using runSequence to make sure all of the things run together. This is kind of a mess, but it seems to work now:

// Task: Handle icons
// We have to do this in a few steps until
// https://github.com/filamentgroup/gulpicon/issues/1 is resolved
gulp.task('minifyIcons', function() {
  return gulp.src(config.icons.files)
      .pipe(svgmin())
      .pipe(gulp.dest(config.icons.min));
});

// Based on https://github.com/filamentgroup/gulpicon#usage
var iconFiles = glob.sync("source/assets/icons/svg/*.svg");
var iconConfig = require("./source/assets/icons/config.js");
iconConfig.dest = "public/assets/icons/";
gulp.task('makeIcons', gulpicon(iconFiles, iconConfig));

gulp.task('waitForIcons', function(callback) {
  var trigger = iconConfig.dest + 'preview.html';
  return pWaitFor(() => pathExists(trigger, '1000')).then(() => {
    console.log('Yay! The icons now exist.');
  });
});

gulp.task('reloadIcons', function() {
  return gulp.src('', {read: false})
    .pipe(browserSync.reload({stream:true}));
});

gulp.task('icons', function (callback) {
  runSequence('minifyIcons', 'makeIcons', 'waitForIcons', 'reloadIcons', callback);
});

This requires the includes as stated in https://www.npmjs.com/package/p-wait-for.
