/*
## Installing

Add to your _deploy.php_

```php
require 'contrib/newrelic.php';
```

## Configuration

- `newrelic_app_id` – newrelic's app id
- `newrelic_api_key` – newrelic's api key
- `newrelic_description` – message to send

## Usage

Since you should only notify New Relic of a successful deployment, the `newrelic:notify` task should be executed right at the end.

```php
after('deploy', 'newrelic:notify');
```

use Deployer\Utility\Httpie;

set('newrelic_app_id', function () {
    throw new \Exception('Please, configure "newrelic_app_id" parameter.');
});

set('newrelic_description', function() {
    return runLocally('git log -n 1 --format="%an: %s" | tr \'"\' "\'"');
});

set('newrelic_revision', function() {
    return runLocally('git log -n 1 --format="%h"');
});
