Grunt，CSSComb和Watch针对所有文件，而不仅仅是新文件

Question

我有csscomb正常运行，它会触发监视，但是有没有办法让csscomb对我正在处理的scss文件运行，而不是在我的项目中运行它们？

这是我的Gruntgile.js。 csscomb设置很奇怪，因为我有两个根文件夹中的sass文件。

Answer 1

使用grunt-newer

https://github.com/tschaub/grunt-newer

然后将css任务更改为

grunt.registerTask('css', [
   'newer:csscomb',
   'compass:dev'
]);
