Recursive and non-recursive prompt together in Yeoman - recursion

Question

I'm building a Yeoman generator, and have some prompts for the user, I use a prompt queue like this:
var prompts = [{
name: 'name',
message: 'What is the name of this module?'
},{
name: 'desc',
message: 'Describe your module:'
}];
this.prompt(prompts, function (props) {
this.name = props.name;
this.desc = props.desc;
done();
}.bind(this));
But how can I add a recursive question to this prompt? I want to ask the user for dependencies, and let them fill in a name, press enter, fill in another name, until they press enter with a blank answer.

Answer 1

After some attempts i found a solution that works:
var dependencies = [];
var dependency = function(self) {
var dep_quest = {
name: "dependency",
message: "Need any dependencies? (Leave blank to continue)"
};
self.prompt([dep_quest], function(props)
if (props.dependency !== '') {
dependencies.push(props.dependency);
dependency(self);
}
else {
self.dependencies = dependencies;
done();
}
});
}
this.prompt(prompts, function (props) {
this.name = props.name;
this. desc = props.desc;
dependency(self);
}.bind(this));
After the regular questions i call the dependency function that asks one question again and again until a blank answer is provided. Then it calls the done() function.
