You type the first parameter of the function, `first_name`, then a dot (`.`) and then hit `Ctrl+Space` to trigger the completion.

But, sadly, you get nothing useful:

### Add types { #add-types }

Let's modify a single line from the previous version.

We will change exactly this fragment, the parameters of the function, from:

```Python
    first_name, last_name
```

to:

		}
		var hint string
		if endpoint.URL != nil {
			hint = fmt.Sprintf("Run the following command to add write permissions: `sudo chown -R %s %s && sudo chmod u+rxw %s`",
				username, endpoint.Path, endpoint.Path)
		} else {
			hint = fmt.Sprintf("Run the following command to add write permissions: `sudo chown -R %s. <path> && sudo chmod u+rxw <path>`", username)
		}
		if !exit {

    val proxySelector = RecordingProxySelector()
    val socketAddress = InetSocketAddress.createUnresolved("myproxy", 8008)
    proxySelector.proxies.add(Proxy(Proxy.Type.HTTP, socketAddress))

    // Define two host names for the DNS routing of fake proxy servers
    val proxyServer1 = InetAddress.getByAddress("proxyServer1", byteArrayOf(127, 0, 0, 2))

### Custom OpenAPI *path operation* schema { #custom-openapi-path-operation-schema }

The dictionary in `openapi_extra` will be deeply merged with the automatically generated OpenAPI schema for the *path operation*.

So, you could add additional data to the automatically generated schema.

// Supported status types
const (
	Enabled  Status = "Enabled"
	Disabled Status = "Disabled"
)

// DeleteMarkerReplication - whether delete markers are replicated - https://docs.aws.amazon.com/AmazonS3/latest/dev/replication-add-config.html
type DeleteMarkerReplication struct {
	Status Status `xml:"Status"` // should be set to "Disabled" by default
}

// IsEmpty returns true if DeleteMarkerReplication is not set

                """
            ),
        ] = Default(generate_unique_id),
    ) -> Callable[[DecoratedCallable], DecoratedCallable]:
        """
        Add a *path operation* using an HTTP GET operation.

        ## Example

        ```python
        from fastapi import APIRouter, FastAPI

        app = FastAPI()
        router = APIRouter()

        for (int i = 0; i < 100; i++) {
            SID groupSid = mock(SID.class);
            List<SID> members = new ArrayList<>();
            for (int j = 0; j < 50; j++) {
                members.add(mock(SID.class));
            }
            largeMap.put(groupSid, members);
        }

        when(sidResolver.getLocalGroupsMap(any(CIFSContext.class), anyString(), anyInt())).thenReturn(largeMap);

    // retry, we return true and try a new route.
    return true
  }
