# Comm
|
|
|
|
It provides a way to register a Kernel Comm implementation, as per the Jupyter kernel protocol.
|
|
It also provides a base Comm implementation and a default CommManager that can be used.
|
|
|
|
## Register a comm implementation in the kernel:
|
|
|
|
### Case 1: Using the default CommManager and the BaseComm implementations
|
|
|
|
We provide default implementations for usage in IPython:
|
|
|
|
```python
|
|
import comm
|
|
|
|
|
|
class MyCustomComm(comm.base_comm.BaseComm):
|
|
|
|
def publish_msg(self, msg_type, data=None, metadata=None, buffers=None, **keys):
|
|
# TODO implement the logic for sending comm messages through the iopub channel
|
|
pass
|
|
|
|
|
|
comm.create_comm = MyCustomComm
|
|
```
|
|
|
|
This is typically what ipykernel and JupyterLite's pyolite kernel will do.
|
|
|
|
### Case 2: Providing your own comm manager creation implementation
|
|
|
|
```python
|
|
import comm
|
|
|
|
comm.create_comm = custom_create_comm
|
|
comm.get_comm_manager = custom_comm_manager_getter
|
|
```
|
|
|
|
This is typically what xeus-python does (it has its own manager implementation using xeus's C++ messaging logic).
|
|
|
|
## Comm users
|
|
|
|
Libraries like ipywidgets can then use the comms implementation that has been registered by the kernel:
|
|
|
|
```python
|
|
from comm import create_comm, get_comm_manager
|
|
|
|
# Create a comm
|
|
comm_manager = get_comm_manager()
|
|
comm = create_comm()
|
|
|
|
comm_manager.register_comm(comm)
|
|
```
