Plugin's API

The console is integrated with ImJoy, you can use the ImJoy API to control the console.

API	Description	Parameters
.echo	Print a message to the console	msg: string
.clear	Clear the console
.exec	Execute Python code	code: string; show_code: bool = true
.restart	Restart the console
.get_content	Get the content of the console

.ready	A promise that resolves when the console is ready

Using ImJoy API in the console

You can also control other ImJoy plugins from the console using ImJoy API. For example, you can use the following code to control the ImageJ.JS:

import numpy as np

arr = np.random.randint(0, 255, (100,100), dtype=np.uint8)

ij = await api.createWindow(src="https://ij.imjoy.io")
await ij.viewImage(arr)

The complete ImJoy API can be found here.

Additonal APIs

API	Description	Parameters
api.restart	Restart the console
api.insertHtml	Insert HTML to the console	html: string; width: string; height: string
api.mountNativeFs	Mount a native file system to the console	mountPoint: string;
api.openEditor	Open a Python script editor

Usage example:

# restart the console
await api.restart()
# insert HTML as an iframe
await api.insertHtml("<h1>Hello World</h1>", width="100%", height="100px")
