# Vincenzo
Vincenzo is a BitTorrent client with vim-like keybindings and a terminal based UI.

## Introduction
Vincenzo aims to be a fast, lightweight, and multi-platform client.

Another goal is for users to be able to use the [library](crates/vincenzo) to create any other kind of software, that is powered by the BitTorrent protocol.

The official UI binary is very niched, targeting a very specific type of user: someone who loves using the terminal, and vim keybindings. Altough users could create other UIs using the library.

Vincenzo offers 3 binaries and 1 library:

- [vcz](crates/vcz) - Main binary with both UI and daemon.
- [vcz_ui](crates/vcz_ui) - UI binary.
- [vczd](crates/vcz_daemon) - Daemon binary.
- [vincenzo](crates/vincenzo) - Library

## Features
- Multi-platform.
- Multithreaded. One OS thread specific for I/O.
- Async I/O with tokio.
- Communication with daemon using CLI flags, TCP messages or remotely via UI binary.
- Detached daemon from the UI.
- Support for magnet links.

## How to use
Downloading a torrent using the main binary (the flags are optional and could be omitted in favour of the configuration file).

```bash
vcz -d "/tmp/download_dir" -m "" -q
```

## Configuration
The binaries read a toml config file.
It is located at the default config folder of your OS.
- Linux: ~/.config/vincenzo/config.toml
- Windows: C:\Users\Alice\AppData\Roaming\Vincenzo\config.toml
- MacOS: /Users/Alice/Library/Application Support/Vincenzo/config.toml

### Default config file:
```toml
download_dir = "/home/alice/Downloads"
# default
daemon_addr = "127.0.0.1:3030"
```

## Daemon and UI binaries
Users can control the Daemon by using CLI flags that work as messages.

Let's say on one terminal you initiate the daemon: `vczd`. Or spawn as a background process so you can do everything on one terminal: `vczd &`.

And you open a second terminal to send messages to the daemon, add a torrent: `vczd -m "magnet:..."` and then print the stats to stdout `vczd --stats`.

You can also run the UI binary (maybe remotely from another machine) to control the Daemon: `vcz_ui --daemon-addr 127.0.0.1:3030`.

CLI flags of Daemon

```
Usage: vczd [OPTIONS]

Options:
--daemon-addr The Daemon will accept TCP connections on this address
-d, --download-dir The directory in which torrents will be downloaded
-m, --magnet Download a torrent using it's magnet link, wrapped in quotes
-q, --quit-after-complete If the program should quit after all torrents are fully downloaded
-s, --stats Print all torrent status on stdout
-h, --help Print help
-V, --version Print version
```
