gulp rev manifest 添加目录前缀

gulp-rev 生成的manifest默认为：

?

1	"index.css": "index.css?v=04aff97a7b",

　　为避免同名文件覆盖版本号，对替换的路径增加一级目录，如下

?

1	"css/index.css": "css/index.css?v=04aff97a7b",

　

修改gulp-rev下index.js，

123行增加manifest传入参数:

?

1 2 3 4 5 6 7 8 9

opts = objectAssign({         path: 'rev-manifest.json',         merge: false,         // Apply the default JSON transformer.         // The user can pass in his on transformer if he wants. The only requirement is that it should         // support 'parse' and 'stringify' methods.         transformer: JSON,         pwd_base: '' //增加一级目录     }, opts, pth);

　　

146行增加：

?

1	originalFile = opts.pwd_base + originalFile;

　　gulp文件配置增加目录：

?

1	.pipe(rev.manifest({ pwd_base: 'css/' }))
