Module: core.displaypub
An interface for publishing rich data to frontends.
There are two components of the display system:
- Display formatters, which take a Python object and compute the
representation of the object in various formats (text, HTML, SVG, etc.).
- The display publisher that is used to send the representation data to the
various frontends.
This module defines the logic display publishing. The display publisher uses
the display_data message type that is defined in the IPython messaging
spec.
Authors:
1 Class
-
class IPython.core.displaypub.DisplayPublisher(**kwargs)
Bases: IPython.config.configurable.Configurable
A traited class that publishes display data to frontends.
Instances of this class are created by the main IPython object and should
be accessed there.
-
clear_output(stdout=True, stderr=True, other=True)
Clear the output of the cell receiving output.
-
publish(source, data, metadata=None)
Publish data and metadata to all frontends.
See the display_data message in the messaging documentation for
more details about this message type.
The following MIME types are currently implemented:
- text/plain
- text/html
- text/latex
- application/json
- application/javascript
- image/png
- image/jpeg
- image/svg+xml
Parameters: | source : str
A string that give the function or method that created the data,
such as ‘IPython.core.page’.
data : dict
A dictionary having keys that are valid MIME types (like
‘text/plain’ or ‘image/svg+xml’) and values that are the data for
that MIME type. The data itself must be a JSON’able data
structure. Minimally all data should have the ‘text/plain’ data,
which can be displayed by all frontends. If more than the plain
text is given, it is up to the frontend to decide which
representation to use.
metadata : dict
A dictionary for metadata related to the data. This can contain
arbitrary key, value pairs that frontends can use to interpret
the data. Metadata specific to each mime-type can be specified
in the metadata dict with the same mime-type keys as
the data itself.

1 Function
-
IPython.core.displaypub.publish_display_data(source, data, metadata=None)
Publish data and metadata to all frontends.
See the display_data message in the messaging documentation for
more details about this message type.
The following MIME types are currently implemented:
- text/plain
- text/html
- text/latex
- application/json
- application/javascript
- image/png
- image/jpeg
- image/svg+xml
Parameters: | source : str
A string that give the function or method that created the data,
such as ‘IPython.core.page’.
data : dict
A dictionary having keys that are valid MIME types (like
‘text/plain’ or ‘image/svg+xml’) and values that are the data for
that MIME type. The data itself must be a JSON’able data
structure. Minimally all data should have the ‘text/plain’ data,
which can be displayed by all frontends. If more than the plain
text is given, it is up to the frontend to decide which
representation to use.
metadata : dict
A dictionary for metadata related to the data. This can contain
arbitrary key, value pairs that frontends can use to interpret
the data. mime-type keys matching those in data can be used
to specify metadata about particular representations.
