Note

This documentation is for a development version of IPython. There may be significant differences from the latest stable release.

Module: kernel.zmq.kernelbase

Base class for a kernel that talks to frontends over 0MQ.

1 Class

class IPython.kernel.zmq.kernelbase.Kernel(**kwargs)

Bases: IPython.config.configurable.SingletonConfigurable

__init__(**kwargs)

abort_request(stream, ident, parent)

abort a specific msg by id

clear_request(stream, idents, parent)

Clear our namespace.

dispatch_control(msg)

dispatch control requests

dispatch_shell(stream, msg)

dispatch shell requests

do_apply(content, bufs, msg_id, reply_metadata)

Override in subclasses to support the IPython parallel framework.

do_clear()

Override in subclasses to clear the namespace

This is only required for IPython.parallel.

do_complete(code, cursor_pos)

Override in subclasses to find completions.

do_execute(code, silent, store_history=True, user_experssions=None, allow_stdin=False)

Execute user code. Must be overridden by subclasses.

do_history(hist_access_type, output, raw, session=None, start=None, stop=None, n=None, pattern=None, unique=False)

Override in subclasses to access history.

do_inspect(code, cursor_pos, detail_level=0)

Override in subclasses to allow introspection.

do_is_complete(code)

Override in subclasses to find completions.

do_one_iteration()

step eventloop just once

do_shutdown(restart)

Override in subclasses to do things when the frontend shuts down the kernel.

enter_eventloop()

enter eventloop

execute_request(stream, ident, parent)

handle an execute_request

getpass(prompt='')

Forward getpass to frontends

Raises:StdinNotImplentedError if active frontend doesn’t support stdin. :

raw_input(prompt='')

Forward raw_input to frontends

Raises:StdinNotImplentedError if active frontend doesn’t support stdin. :

record_ports(ports)

Record the ports that this kernel is using.

The creator of the Kernel instance must call this methods if they want the connect_request() method to return the port numbers.

send_response(stream, msg_or_type, content=None, ident=None, buffers=None, track=False, header=None, metadata=None)

Send a response to the message we’re currently processing.

This accepts all the parameters of IPython.kernel.zmq.session.Session.send() except parent.

This relies on set_parent() having been called for the current message.

set_parent(ident, parent)

Set the current parent_header

Side effects (IOPub messages) and replies are associated with the request that caused them via the parent_header.

The parent identity is used to route input_request messages on the stdin channel.

start()

register dispatchers for streams
