A command line tool for interacting with a Zenoh session.

Typical use cases include:

• Tests

zenoh-cli makes use of codecs for encoding and decoding to and from the wire payloads on the zenoh network bus. By default, zenoh-cli bundles the following codecs:

• text
• base64
• JSON

A plugin system is in place to allow for easily extending the available codecs in zenoh-cli, see below.

pip install zenoh-cli

usage: zenoh [-h] [--mode {peer,client}] [--connect CONNECT] [--listen LISTEN] [--config CONFIG] [--log-level LOG_LEVEL] {info,network,scout,delete,put,subscribe,get} ...

Zenoh command-line client application

positional arguments:
  {info,network,scout,delete,put,subscribe,get}

options:
  -h, --help            show this help message and exit
  --mode {peer,client}
  --connect CONNECT     Endpoints to connect to. (default: None)
  --listen LISTEN       Endpoints to listen on. (default: None)
  --config CONFIG       A path to a configuration file. (default: None)
  --log-level LOG_LEVEL

zenoh-cli comes with a plugin system for easily extending it with custom encoders and decoders (codecs) for the data values. The plugin system makes use of the entrypoints provided by setuptools, see here for details. zenoh-cli gather plugins from two custom "groups":

• zenoh_cli.codecs.encoders
• zenoh_cli.codecs.decoders
