Working with ansible-vault

---

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

// Create a new layer which is the width of the device and with a heigh
// of 0.5px.
CALayer *topBorder = [CALayer layer];
topBorder.frame = CGRectMake(0.0f, 0.0f, self.view.frame.size.width, 0.5f);

// Set the background colour of the new layer to the colour you wish to
// use for the border.
topBorder.backgroundColor = [[UIColor blueColor] CGColor];

// Add the later to the tab bar's existing layer

A result type (based on swiftz) that can represent either an error or success:

enum Result<X, T> {
  case Err(() -> X)
  case Ok(() -> T)
}

Now we need a way to chain multiple results together without lots of nesting of if statements -- or exceptions. To do so, we can define a new bind (result, next) operator (implementation borrowed from swiftz) that operates on Result types (a.k.a flatMap or >>=):

• If the result is Err, the result is immediately returned.
