Usage

Nuze is available on crates.io:

cargo install nuze

A REPL instance supports multiple Zenoh sessions each identified with a name (a Nu string). On startup, a session named default is created. All commands use this session unless the argument --session (-s) is supplied:

$ nuze
41aa8953> zenoh session list
╭───┬─────────┬──────────────────────────────────╮
# │  name   │               zid                │
├───┼─────────┼──────────────────────────────────┤
│ 0 │ default │ 41aa8953ad1abda60a9149e25c54067d │
╰───┴─────────┴──────────────────────────────────╯
41aa8953> zenoh zid -s default --short
41aa8953

If you would like to start Nuze without the default session, use the --no-default-session (-0) argument.

The Nuze CLI can be consulted with:

$ nuze --help

To get the list of available commands:

41aa8953> help zenoh

To get help on a specific command:

41aa8953> help zenoh liveliness declare-token
