Programmatically pass arguments to grunt task?

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.js and lib/grunt/task.js, but couldn't figure it out.

I'm using grunt-compass with the following arguments specified in Gruntfile.js:

compass: {

  default_options: {

    src: 'components/201',

    dest: 'build',

    require: ['zurb-foundation']

  }

}

I want to be able to override them at runtime:

tasks/my-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:

$ grunt --version

grunt-cli v0.1.6

grunt v0.4.0rc6

I figured it out. Use the <%= %> syntax in Gruntfile.js:

compass: {

  default_options: {

    src: 'components/<%= myTask.src %>',

    dest: 'build',

    require: ['zurb-foundation']

  }

}

Then you can set it in your task:

grunt.config.set('myTask.src', getSrc());
