Yeoman uses a thing called Inquirer.js for the prompt system. Here's an example of how you can ask Question 2 if Question 1 was true:
inquirer.prompt([{
name: 'movie',
type: 'confirm',
message: 'Have you seen a movie lately?'
}, {
when: function (response) {
return response.movie;
},
name: 'good-or-not',
message: 'Sweet! Was it any good?'
}], function (response) {});
From the Inquirer.js documentation:
when: (Function) Receive the current user answers hash and should return true or false depending on wheter or not this question should be asked.

How would you add on a question if it was true though?

@cameronroe If the user answers 'no' to the question 'Have you seen a movie lately?' then the next message will not display. To add another question after 'Sweet! Was it any good?', add another when: function(response){} with the same syntax. You can also change the type for subsequent questions.

@Our_Benefactors, the
first argument in the when() method is the answers-hash. So if you don't have the required answer for the question, you can return false; in the method function. For example : when: function(ans){ if(ans.prompt1 === false) {return false;} else {return true;}}. Good Luck...

Is there a way to pass the params in when to the prompt? I generated a list in the when and I need to pass that list as the choices for the current promt.
