Grunt命令行参数 [英] Grunt Command Line Parameters

问题描述

我有一个Grunt构建文件。我的构建文件的任务如下所示：

  myTask：{
 options：{
 configFile：config / default.js，
 args：{} 
}，
 dev：{
 configFile：'config / local.js'，
 options ：{args：{}}，
}，
 test：{
 configFile：'config / remote.js'，
 options：{args：{}} 
 
 
 $ / code $ / pre 
 
 $ p 
 
 
  grunt.registerTask（'customTask'，['myTask：dev']）; 
 grunt.registerTask（'customTask-Test'，['myTask：test']）; 
  
目前，我可以从命令行运行以下命令：
 > grunt customTask 
  
一切正常。但是，我需要添加这样的功能： 
 
 
 > grunt customTask --myParam = myValue 
  
我需要在dev中查看myParam的值，任务目标。但是，我无法弄清楚如何去做。 
如果我可以在运行myTask：dev时打印出myParam的值，我会很高兴。换句话说，
我想在运行时看到以下内容： 
 
 
 > grunt customTask 
 
> grunt customTask --myParam = hello 
您输入了hello 
 
> grunt customTask-Test 
 
> grunt customTask-Test --myParam = hello 
  
我该如何做这样的事情？
解决方案
这些都在 grunt.option 页面。 
 
 
 
您的情况可以通过以下方式获得 myParam 的值：
  var target = grunt.option（'myParam'）; 
  
 
I have a Grunt build file. My build file has a task that looks like the following:
myTask: {
  options: {
    configFile: "config/default.js",
    args: {   }
  },
  dev: {
    configFile: 'config/local.js',
    options: { args: {} },
  },
  test: {
    configFile: 'config/remote.js',
    options: { args: {} }
  }
}
...
grunt.registerTask('customTask', ['myTask:dev']);
grunt.registerTask('customTask-Test', ['myTask:test']);
Currently, I can run the following from the command line:
> grunt customTask
Everything works fine. However, I need to add the ability to do something like this:
> grunt customTask --myParam=myValue
I need to look at the value of myParam in my "dev" task target. However, I can't figure out how to do it.
I would be happy if I could just print out the value of myParam when myTask:dev is ran. In other words,
I'd like to see the following when run
> grunt customTask

> grunt customTask --myParam=hello
You entered hello

> grunt customTask-Test

> grunt customTask-Test --myParam=hello
How do I do something like this?
解决方案
This is all explained in the grunt.option page. 

In your case, you could get the value of myParam with:
var target = grunt.option('myParam');
