## Setup

Install gem:

```
gem install script
```

And require it in your script file:

```
require 'script'
```

## Usage

### Steps

Reason about the step as a logical group of commands. Lets take for instance, the deploy script which builds a docker image, pushes it to Dockerhub and eventually creates the deployment on Kubernetes.

```ruby
#!/usr/local/bin/ruby

require "script"

deploy = Script.new

deploy.step("Setup tools") do

  `sudo apt-get install -y google-cloud-sdk kubectl`
  `gcloud auth activate-service-account $GCLOUD_SERVICE_ACCOUNT_NAME`
  `gcloud config set project dummy-project`
  `gcloud container clusters get-credentials default --zone us-east`
  
end

deploy.step("Deploy docker image") do

  `docker pull dummy`
  `docker build --cache-from dummy -t dummy`
  `docker build -t scripter/script .`
  `docker push dummy`
  
end

deploy.step("Deploy to Kubernetes cluster") do

  `kubectl apply -f k8s.yml --record`
  
end

# Finally, run the script

deploy.run
```

The steps are run in order in which they are registered.
