Nu Plugin From Bencode

A converter plugin from the bencode format for Nushell.

The plugin was last tested on nushell version 0.90.1.

The plugin is unstable as the interface Nu for plugins is unstable.

The plugin could be useful for inspecting a BitTorrent metainfo file (*.torrent), but it is primarily used to explore writing a Nu plugin.

Installation

cargo install nu_plugin_from_bencode

Register the plugin:

register <path to plugin>/nu_plugin_from_bencode

By default, cargo installs to $HOME/.cargo/bin on Unix systems.

Usage

The from bencode command is provided with no parameter arguments.

To use:
