nu_plugin_msgpack

A plugin for nushell that provides the commands from msgpack and to msgpack to convert between Nu types and MsgPack, which is a JSON-like binary serialization format.

Installation

# download and install the plugin
cargo install --git https://github.com/hulthe/nu_plugin_msgpack.git

# register the plugin with nu, you should put this in your `config.nu`
register ~/.cargo/bin/nu_plugin_msgpack

Quirks

There's not a 1 to 1 mapping between Nu-types and MsgPack-types. Here are some conversions that to msgpack does which might trip you up:

• filesize becomes an integer of bytes. This is consistent with to json.
• duration becomes an integer of nanoseconds. This is consistent with to json.
• range becomes an array. This is consistent with to json.
• The following Nu types become nil: block, closure, error, cell_path, and match_pattern.

Additionally Nu dates are converted to the MsgPack timestamp extension type. This differs from to json which converts dates to strings.
