gruntjs加载外部配置 [英] gruntjs load external config

问题描述

Ahoy grunt-master！

我想将外部配置文件加载到grunt中，以便我可以这样做：

$ grunt dev：homepage

它会载入 homepage-config.json ，然后运行 watch

$ grunt dev：contact

它会载入 contact-config.json ，然后运行 watch

每个配置文件都会为任务提供一个特定的设置：watch，jshint，concat，等等......

在我的Gruntfile中，我有一个名为 dev的任务

  grunt.registerTask（'dev'，'load in external -config.json file，then runs watch'，function（name）{
 
 grunt.initConfig（grunt.file.readJSON（name +'-config.json'））; 
 
 console.log（grunt.config（'jshint.pageConfig.src'）//正确记录无论在我的外部json文件中指定
 
 grunt.task.r un（'watch'）; //用外部文件
 
}）指定的配置正确启动watch; 
  

在 dev 任务中，外部加载的配置工作得很好。那个console.log会返回你所期望的，并且 watch 任务开始于外部指定的设置。

我的问题是，一旦 watch 开始触发任务，那些任务似乎不再可以访问这个外部加载的配置。在 dev 任务和 watch 触发的任务之间的某处，动态加载的配置会被取消。

任何人都可以阐明为什么会发生这种情况，以及我可能如何实现目标？

非常感谢，

解决方案

您需要在手表中指定 nospawn：true 任务配置，以便被调用的任务在相同的上下文中运行。有关更多信息/示例，请参阅文档的本节。

Ahoy grunt-masters!

I would like to load external config files into grunt so that I can do something like this:

$ grunt dev:homepage

and it would load in homepage-config.json, then run watch

$ grunt dev:contact

and it would load in contact-config.json, then run watch

Each config file would provide a particular setup for tasks: watch, jshint, concat, etc...

Inside my Gruntfile I have a task called dev

grunt.registerTask('dev', 'loads in external -config.json file, then runs watch', function(name) {

  grunt.initConfig(grunt.file.readJSON(name + '-config.json'));

  console.log(grunt.config('jshint.pageConfig.src') // correctly logs whatever had been specified in my external json file

  grunt.task.run('watch'); // correctly boots up watch with configuration specified by external file

});

Within that dev task the externally loaded config works just fine. That console.log would return what you'd expect, and the watch task kicks off with the externally specified setup.

My problem is that once that watch starts triggering tasks, those tasks no longer seem to have access to this externally loaded config. Somewhere between the dev task and the tasks triggered by watch, the dynamically loaded config gets blown away.

Can anyone shed light on why this is happening and how I might accomplish my goal?

Many thanks, -James

解决方案

You need to specify nospawn : true in your watch task configuration so that the called tasks run in the same context. See this section of the docs for more info/examples.
