--------------------------------

### Quickstart: Basic Greenstalk Operations

Source: https://github.com/justinmayhew/greenstalk/blob/main/README.rst

This snippet demonstrates the fundamental usage of the Greenstalk client, including connecting to a beanstalkd server, putting a job onto the queue, reserving a job, accessing its properties, deleting it, and closing the client connection. Ensure a beanstalkd instance is running on the default host and port.

```pycon
>>> import greenstalk
>>> client = greenstalk.Client(('127.0.0.1', 11300))
>>> client.put('hello')
1
>>> job = client.reserve()
>>> job.id
1
>>> job.body
'hello'
>>> client.delete(job)
>>> client.close()
```

--------------------------------

### Consumer Example

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/index.md

Example of a consumer reserving, processing, and deleting a job from the queue. Requires the greenstalk library.

```python3
import greenstalk

with greenstalk.Client(('127.0.0.1', 11300)) as client:
    while True:
        job = client.reserve()
        print(job.body)
        client.delete(job)
```

--------------------------------

### Import Greenstalk Library

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Start by importing the Greenstalk library to use its functionalities.

```pycon3
>>> import greenstalk
```

--------------------------------

### Consumer: Receive and Deserialize JSON Job

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Example of a consumer reserving a job, deserializing the JSON string body, and extracting data.

```python3
job = client.reserve()
payload = json.loads(job.body)
send_registration_email(payload['user_id'])
```

--------------------------------

### Producer: Send JSON Serialized Job

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Example of a producer serializing a Python dictionary to a JSON string before sending it as a job body.

```python3
payload = {'user_id': user_id}
body = json.dumps(payload)
client.put(body)
```

--------------------------------

### Create a Greenstalk Client (Unix Domain Socket)

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Instantiate a Client object to connect to a beanstalkd server using a Unix domain socket path.

```pycon3
>>> client = greenstalk.Client('/var/run/beanstalkd/socket')
```

--------------------------------

### Create a Greenstalk Client (TCP/IP)

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Instantiate a Client object to connect to a beanstalkd server running on a specific host and port using TCP/IP.

```pycon3
>>> client = greenstalk.Client(('127.0.0.1', 11300))
```

--------------------------------

### Reserve and Consume a Job

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Use the 'reserve' method to retrieve a job from the watch list. It blocks until a job is available or a timeout occurs.

```pycon3
>>> job = client.reserve()
>>> job.id
1
>>> job.body
'hello'
```

--------------------------------

### Insert a Job

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

Use the 'put' method to insert a job into the currently used tube. The job body is the only required argument.

```pycon3
>>> client.put('hello')
1
```

--------------------------------

### Delete a Reserved Job

Source: https://github.com/justinmayhew/greenstalk/blob/main/docs/overview.md

After successfully processing a job, use the 'delete' method to permanently remove it from the server.

```pycon3
>>> client.delete(job)
```
