Programmatically pass arguments to grunt task?
提问by Nick Heiner
I have a grunt task that calls other grunt tasks. I want to call a subtask with programmatically determined arguments. Is this possible? I spent some time digging around the lib/grunt.jsand lib/grunt/task.js, but couldn't figure it out.
我有一个调用其他 grunt 任务的 grunt 任务。我想使用以编程方式确定的参数调用子任务。这可能吗？我花了一些时间在lib/grunt.js和lib/grunt/task.js周围挖掘，但无法弄清楚。
I'm using grunt-compasswith the following arguments specified in Gruntfile.js:
我正在使用Gruntfile.js 中grunt-compass指定的以下参数：
compass: {
default_options: {
src: 'components/201',
dest: 'build',
require: ['zurb-foundation']
}
}
I want to be able to override them at runtime:
我希望能够在运行时覆盖它们：
tasks/my-task.js:
任务/我的-task.js：
// simplified example
module.exports = function(grunt) {
grunt.registerTask('foo', 'bar', function() {
var chooseDest = doWork();
grunt.task.run('compass', {src: 'src', dest: chooseDest});
});
};
For reference:
以供参考：
$ grunt --version
grunt-cli v0.1.6
grunt v0.4.0rc6

I figured it out. Use the <%= %>syntax in Gruntfile.js:
我想到了。使用<%= %>Gruntfile.js 中的语法：
compass: {
default_options: {
src: 'components/<%= myTask.src %>',
dest: 'build',
require: ['zurb-foundation']
}
}
Then you can set it in your task:
然后你可以在你的任务中设置它：
grunt.config.set('myTask.src', getSrc());
回答by Thomas Decaux
You can edit all the Grunt config:
您可以编辑所有 Grunt 配置：
grunt.config('compass.default_options.src', 'blabla');
Just before run the task. But your solution is "cleaner".
就在运行任务之前。但是您的解决方案“更干净”。
