napari-listener 0.1.0b1

Control napari via local socket.

napari-listener

Opens a socket to listen for commands to control napari from other processes. This can be useful for controlling napari programmatically from other applications, or for improving general OS integration (e.g. opening data from a file or UrL in a running instance of napari).

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation

You can install napari-listener via pip:

pip install napari-listener

Usage

Once installed, napari-listener can be started from the napari > Plugins > Start Listening menu. You will see a new docked widget that displays the address and port for the listener.

The listener is a TCP server that expects app-model command IDs. It will execute any valid app-model command, but napari-listener registers its own additional commands for demonstration purposes in https://github.com/aganders3/napari-listener/blob/main/src/napari_listener/_actions.py.

You can test napari-listener using a TCP client such as netcat or curl to send an app-model command (and optional args). For example:

% nc 127.0.0.1 40256 <<< "napari:open-file /path/to/local/file"
