audio

Class

Displays an audio clip as a widget.

The value of this widget accepts a byte string. The byte string is the raw audio data that you want the browser to display. You can explicitly define the format of the byte string using the format trait (which defaults to “mp3”).

If you pass "url" to the "format" trait, value will be interpreted as a URL as bytes encoded in UTF-8.

image

Class

Displays an image as a widget.

The value of this widget accepts a byte string. The byte string is the raw image data that you want the browser to display. You can explicitly define the format of the byte string using the format trait (which defaults to “png”).

If you pass "url" to the "format" trait, value will be interpreted as a URL as bytes encoded in UTF-8.

output

Class

Widget used as a context manager to display output.

This widget can capture and display stdout, stderr, and rich output. To use it, create an instance of it and display it.

You can then use the widget as a context manager: any output produced while in the context will be captured and displayed in the widget instead of the standard output area.

Example

(use-package :jupyter-widgets)
(defvar out (make-instance 'output))
(with-output out
  (print "prints to output area")

sidecar

Class

Widget used as a context manager to display output.

This widget can capture and display stdout, stderr, and rich output. To use it, create an instance of it and display it.

You can then use the widget as a context manager: any output produced while in the context will be captured and displayed in the widget instead of the standard output area.

Example

(use-package :jupyter-widgets)
(defvar out (make-instance 'output))
(with-output out
  (print "prints to output area")

video

Class

Displays a video as a widget.

The value of this widget accepts a byte string. The byte string is the raw video data that you want the browser to display. You can explicitly define the format of the byte string using the format trait (which defaults to “mp4”).

If you pass "url" to the "format" trait, value will be interpreted as a URL as bytes encoded in UTF-8.
