// gulp 对象，提供了若干方法

// 处理css

gulp.task('css', function () {
//解决异步的问题
	return gulp.src('./public/less/main.less')
		.pipe(less())
		.pipe(cssmin())
		.pipe(autoprefixer())
		.pipe(rev())
		.pipe(gulp.dest('./release/public/css'))
		.pipe(rev.manifest())
		.pipe(rename('css-manifest.json'))
		.pipe(gulp.dest('./release/rev'));

});

// 处理图片

gulp.task('image', function () {
  return gulp.src(['./public/images/**/*', './uploads/*'], {base: './'})
	.pipe(imagemin())
	.pipe(rev())
	.pipe(gulp.dest('./release'))
	.pipe(rev.manifest())
	.pipe(rename('image-manifest.json'))
	.pipe(gulp.dest('./release/rev'));

});

// 处理js

gulp.task('useref', function () {
  return gulp.src('./index.html')
	.pipe(useref())
	.pipe(gulpif('*.js', uglify()))
	.pipe(gulpif('*.js', rev()))
	.pipe(gulp.dest('./release'))
	.pipe(rev.manifest())
	.pipe(rename('js-manifest.json'))
	.pipe(gulp.dest('./release/rev'));

});

// 其它

gulp.task('other', function () {
  return gulp.src(['./api/*', './public/fonts/*', './public/libs/*', './views/*.html'],       {base: './'})
	.pipe(gulp.dest('./release'));

});

// 替换

gulp.task('rev', ['css', 'image', 'useref'], function () {
  gulp.src(['./release/rev/*.json', './release/index.html'])
	.pipe(revCollector())
	.pipe(gulp.dest('./release'));

}); //[]依赖

//gulp 默认执行
gulp.task('default', ['rev', 'other']);

// gulp.task('default', function () {
// 	console.log('默认');
// })

// gulp.task('demo', ['css', 'image'], function () {
// 	console.log(11);
// });
