Overview

Takes an array of ‘requirements` hashes for a dependency at the old version and a new version, and generates a set of new `requirements` hashes at the new version.

A requirements hash is a basic description of a dependency at a certain version constraint, and it includes the data that is needed to update the manifest (i.e. the ‘.tf` file) with the new version.

A requirements hash looks like this for a registry hosted requirement: “‘ruby {

requirement: "~> 0.2.1",
groups: [],
file: "main.tf",
source: {
  type: "registry",
  registry_hostname: "registry.terraform.io",
  module_identifier: "hashicorp/consul/aws"
}

}

And like this for a git requirement: “‘ruby {

requirement: nil,
groups: [],
file: "main.tf",
source: {
  type: "git",
  url: "https://github.com/cloudposse/terraform-null-label.git",
  branch: nil,
  ref: nil
}

}
