pyrlang.notebook module¶

class
pyrlang.notebook.notebook.
Notebook
(options: dict)¶ Bases:
pyrlang.gen_server.GenServer
Implements a flow for performing remote calculations from Erlang on Python node, while storing the results on Python side until they are ready. Each call result is stored in notebook history and a value index is returned to the caller. This index can be used as an argument in subsequent calls.
-
history_
= None¶ Recent calculation results indexed by integers or names.
-
history_ids_
= None¶ Log of recent value ids in their creation order. Values, which were deleted because of history size limit, are also deleted here.
-
history_limit_
= None¶ History dict will be trimmed when its length is greater than this limit to save memory. Attempt to refer to a trimmed value will create value_not_found exception, also propagated to Erlang side.
-
nb_batch
(batch: List[tuple], param: Dict[term.atom.Atom, any])¶ Take a remote call from Erlang to execute batch of Python calls.
-
nb_call
(param: dict)¶ Remote call from
py.erl
: Calls function defined inargs
, stores the result in history.Parameters: param -- contains path
: list of strings where first one is to be imported and remaining are used to find the function;args
: list of arguments for the callable;kwargs
;immediate
: will return the value instead of the value ref if this isTrue
, also will not update the history.Returns: Index for stored history value.
-
nb_retrieve
(value_id)¶ Remote call from
py.erl
: Retrieves a historical value by index.
-
value_id_
= None¶ Next id to be used as result index.

new_context
(options: dict) → term.pid.Pid¶ Create a new remote-call notebook context. Node_name argument will be automatically prepended to args by Rex.
