用来合并html页面里边的js和css，并对js和css增加文件版本号。
var destDir = "dist";
var merge = require('gulp-ya-merge');
gulp.task('merge', function () {
gulp.src('mall/**/*.phtml')
.pipe(merge({
rootPath: process.cwd() + '/share/static/',
}))
.pipe(gulp.dest('/dest/mall/'));
});比如：

<?php if (isset($this->v['mobileUrl'])): ?>
<meta name="mobile-agent" content="format=html5; url=<?= $this->v['mobileUrl'] ?>"/>
<?php endif ?>
<?php if (isset($this->v['is_seo_tag']) && !empty($this->v['is_seo_tag'])): ?>
<!-- <meta name="robots" content="nofollow">-->
<?php endif; ?>
