如何同时运行两个grunt监视任务 [英] How to run two grunt watch tasks simultaneously

问题描述

是否可以同时运行两个监视任务？

据我所知，我可以在 watch 设置中执行任意数量的任务只需启动 grunt watch ，它就会像所有人一样观看它。

  ... 
 watch：{
 A：{
 files：js / dev / ** / *。coffee，
 tasks：[coffee，requirejs] 
}，
 B：{
 files：js / dev / ** / *。coffee，
 tasks：[coffee] 
}，
 C：{
 files：js / dev / ** / *。html，
 tasks：[copy] 
} 
} 
 ... 
  

...但我不需要这个。我只想为开发和生产制定不同的任务。正如你所猜测的那样， A （制作）和 B （开发）之间的唯一区别是缩小和拼接。我不需要同时启动 A 和 B 任务。 首先，我带着这个想法

  grunt.registerTask（prod，[watch：A，watch：C]）; 
 grunt.registerTask（dev，[watch：B，watch：C]）; 
  

但这没有奏效。只是第一个监视任务正在工作（ C 从来没有工作）。是否有可能做我想做的事？

解决方案

我发现使用 grunt-concurrent 工作：

  concurrent：{
 options：{
 logConcurrentOutput：true 
}，
 prod：{
 tasks：[watch：A，watch： C] 
}，
 dev：{
 tasks：[watch：B，watch：C] 
} 
} 
  

然后：

  grunt.registerTask（prod，[concurrent：prod]）; 
 grunt.registerTask（dev，[concurrent：dev]）; 
  

Is it possible to run two watch tasks simultaneously?

I understand that I can have any number of tasks I want inside watch settings and just launch grunt watch and it will watch all of them, like this

...
watch: {
    A: {
        files: "js/dev/**/*.coffee",
        tasks: ["coffee", "requirejs"]
    },
    B: {
        files: "js/dev/**/*.coffee",
        tasks: ["coffee"]
    },
    C: {
        files: "js/dev/**/*.html",
        tasks: ["copy"]
    }
}
...

...but I don't need this. I just want to have different set of tasks for development and production. As you can guess, the only difference between A (production) and B (development) is minification and concatenation. I don't need to launch A and B tasks at the same time.

First I came with this idea

grunt.registerTask("prod", ["watch:A", "watch:C"]);
grunt.registerTask("dev", ["watch:B", "watch:C"]);

But this didn't work. Just first watch tasks is working (C never works). Is that possible to do what I want?

解决方案

I've found using grunt-concurrent works:

concurrent: {
  options: {
    logConcurrentOutput: true
  },
  prod: {
    tasks: ["watch:A", "watch:C"]
  },
  dev: {
    tasks: ["watch:B", "watch:C"]
  }
}

Then:

grunt.registerTask("prod", ["concurrent:prod"]);
grunt.registerTask("dev", ["concurrent:dev"]);
