# Cfn Status

Helper library provides status of CloudFormation stack.

## Usage

Add this line to your gem's gemspec:

```ruby
  gem.add_development_dependency "cfn-status"
```

Require it to your library:

```ruby
require "cfn/status"
```

Use like so:

```ruby
status = Cfn::Status.new(stack_name)
status.run # prints out stack events
```

The `status.run` will:

* print out the most recent stack events and return right away if the stack is in a completed state.
* print out the most recent stack events and poll for more events until the stack in a completed state.

To find out whether the most recent completed state of the stack was a success or a fail, you can use `status.success?`.

```ruby
status.success?
```

If you need to just wait for the stack to complete, you can also use `status.wait`.

```ruby
status.wait
status.success?
```
