torrent
This repository implements BitTorrent-related packages and command-line utilities in Go. The emphasis is on use as a library from other projects. It's been used 24/7 in production by a downstream, private service since late 2014.
There is support for protocol encryption, DHT, PEX, uTP, and various extensions. See the package documentation for a more complete list. There are several data storage backends provided: blob, file, and mmap, and you can write your own, such as to store data on S3, or in a database. You can use the provided binaries in ./cmd
, or use torrent
as a library for your own applications.
Many of the sub-packages can be used for other purposes: dht, bencode, and tracker, in particular.
Installation
Install the library package with go get github.com/anacrolix/torrent
, or the provided cmds with go get github.com/anacrolix/torrent/cmd/...
.
Library example
There is a small example in the package documentation.
Other projects using Torrent
Commands
Here I'll describe what some of the provided commands in ./cmd
do.
Note that the godo
command which is invoked in the following examples builds and executes a Go import path, like go run
. It's easier to use this convention than to spell out the install/invoke cycle for every single example.
torrent
Downloads torrents from the command-line.
$ go get github.com/anacrolix/torrent/cmd/torrent
$ torrent 'magnet:?xt=urn:btih:KRWPCX3SJUM4IMM4YF5RPHL6ANPYTQPU'

torrentfs
torrentfs mounts a FUSE filesystem at -mountDir
. The contents are the torrents described by the torrent files and magnet links at -torrentPath
. Data for read requests is fetched only as required from the torrent network, and stored at -downloadDir
.
$ mkdir mnt torrents
$ godo github.com/anacrolix/torrent/cmd/torrentfs -mountDir mnt -torrentPath torrents &
$ cd torrents
$ wget http://releases.ubuntu.com/14.04.2/ubuntu-14.04.2-desktop-amd64.iso.torrent
