grunt-init template conditional prompts

Question

I'm creating a new grunt-init template for my project and was wondering if there is a way to do conditional prompts based on the answers given to previous prompts.

My main goal is to be able to use the Github API to create an issue when I create a new module in my project. After asking for the module information, I would ask if a Github issue should be created. If yes, then ask for information like assignee, milestone, labels. If no, I don't care about any of those features.

Right now, I can just default them to blanks, but I'd like to just skip those prompts entirely.

The init property exposes a init.prompts() object which you could modify based on the answers.

Something like this:

exports.template = function(grunt, init, done) {
    init.process([
        init.prompt('create_github_issue', function(value, props, done) {
            init.prompts['milestone'] = init.prompt('milestone');
            done();
        })
    ], function(err, props) {
        // handle all the props
        done();
    });
};

See the gruntplugin template for how to implement an init task.
