在运行时将选项传递给一个咕task任务 [英] Pass Options to a grunt task while running it

问题描述

我认为有一种方法可以做到这一点，而我之前曾经偶然发现过。
我已阅读这些答案，但他们不是我所说的：

以编程方式将参数传递给grunt任务？

垃圾条件选项

从咕噜模板访问流程/环境

我也看了一下grunt docs，但它不在那里：

https://github.com/gruntjs/grunt/wiki/Configuring-tasks

是有这样的语法？

$ b grunt.task.run'htmlmin：allFiles：collapseWhitespace = true'
/ code>

解决您可以使用该语法，但它意味着将这些参数传递给htmlmin任务： allFiles ，'collapse = true' 。

例如，给定以下任务：

  grunt.registerTask（'so'，function（arg1，arg2）{
 console.log（arg1 +，+ arg2）; 
}）; 
  

运行：

  grunt so：barley：test = true 
  

提供以下输出：

  barley，test = true 
  

还有其他方法可以传递常见问题中描述的参数/共享信息：如何在多个任务之间共享参数？

- 选项可能适用于您

跨多个任务共享参数的另一种方法是要使用 grunt.option 。在这个例子中，在命令行上运行 grunt deploy --target = staging 会导致 grunt.option（'target'）返回分期。

I thought there was a way to do this, and that I'd stumbled on it before. I have read these answers but they're not what I'm talking about:

Programmatically pass arguments to grunt task?

Grunt conditional option

Accessing the process / environment from a grunt template

I also looked at the grunt docs but it isn't there:

https://github.com/gruntjs/grunt/wiki/Configuring-tasks

Is there a syntax like this?

grunt.task.run 'htmlmin:allFiles:collapseWhitespace=true'

解决方案

You can use that syntax but it means pass these arguments to the htmlmin task: allFiles, 'collapse=true'.

For example, given the following task:

grunt.registerTask('so', function(arg1, arg2) {
   console.log(arg1 + ", " + arg2); 
}); 

Running:

grunt so:barley:test=true

Gives the following output:

barley, test=true

There are other ways to pass parameters/share info described in the faq: How can I share parameters across multiple tasks?

--Options may be applicable to you

Another way to share a parameter across multiple tasks would be to use grunt.option. In this example, running grunt deploy --target=staging on the command line would cause grunt.option('target') to return "staging".
