Adding an array as property of a new key

[amir-rahnama]

gruntConfig = {
        env: {
            //dynamically created. 
            chrome: {
                CAPS: []
            }
        }
};

grunt.registerTask('test:sauce:' + key, ['env:' + key + ':CAPS']);

I dynamically create the above config for grunt-dev but when later I wanna grab the CAPS in my test file, I realize that it is empty.

Why is that?
When I set the gruntConfig.env

When I wanna get the gruntConfig.env

Any updates on this?

This is happening because you are not deep extending the object in the following code chunk:

function add(value, key) {
    if (process.env[key]) return grunt.log.writeln(key + ' already exists, leaving unchanged.');

    var data = {};
    data[key] = value;
    _.extend(process.env, data);
  }

This is expected behavior outside of grunt-env. Environment variables are strings only, so your array is being toString()ed into an empty ""

I'll add this as a reminder in the readme.
