## Getting Started

To install:

`pip install pyzeebe`

For full documentation please visit: https://pyzeebe.readthedocs.io/en/stable/

## Usage

### Worker

The `ZeebeWorker` class gets jobs from the gateway and runs them.

```python
import asyncio

from pyzeebe import ZeebeWorker, Job, create_insecure_channel


channel = create_insecure_channel(hostname="localhost", port=26500) # Create grpc channel
worker = ZeebeWorker(channel) # Create a zeebe worker


async def on_error(exception: Exception, job: Job):
    """
    on_error will be called when the task fails
    """
    print(exception)
    await job.set_error_status(f"Failed to handle job {job}. Error: {str(exception)}")


@worker.task(task_type="example", exception_handler=on_error)
def example_task(input: str) -> dict:
    return {"output": f"Hello world, {input}!"}


@worker.task(task_type="example2", exception_handler=on_error)
async def another_example_task(name: str) -> dict: # Tasks can also be async
    return {"output": f"Hello world, {name} from async task!"}

loop = asyncio.get_running_loop()
loop.run_until_complete(worker.work()) # Now every time that a task with type `example` or `example2` is called, the corresponding function will be called
```

Stop a worker:

```python
await zeebe_worker.stop() # Stops worker after all running jobs have been completed
```

### Client

```python
from pyzeebe import ZeebeClient, create_insecure_channel

# Create a zeebe client
channel = create_insecure_channel(hostname="localhost", port=26500)
zeebe_client = ZeebeClient(channel)

# Run a Zeebe process instance
process_instance_key = await zeebe_client.run_process(bpmn_process_id="My zeebe process", variables={})

# Run a process and receive the result
process_instance_key, process_result = await zeebe_client.run_process_with_result(
    bpmn_process_id="My zeebe process",
    timeout=10000
)

# Deploy a BPMN process definition
await zeebe_client.deploy_process("process.bpmn")

# Cancel a running process
await zeebe_client.cancel_process_instance(process_instance_key=12345)

# Publish message
await zeebe_client.publish_message(name="message_name", correlation_key="some_id")

```

## Tests
