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 have been contributions from people using some various packages for integrating BitTorrent into media and other services.
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.
Commands
Here I'll describe what some of the provided commands in ./cmd do.
Note that godo that I invoke in the following examples is a command that 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
$ cd ..
$ ls mnt
