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](https://github.com/anacrolix/dht), PEX, [uTP](https://github.com/anacrolix/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 package `torrent` as a library for your own applications.
Many of the sub-packages can be used for other purposes: [bencode](https://godoc.org/github.com/anacrolix/torrent/bencode), and [tracker](https://godoc.org/github.com/anacrolix/torrent/tracker), in particular.
Note that the [`godo`](https://github.com/anacrolix/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.
torrentfs mounts a FUSE filesystem at `-mountDir`. The contents are the torrents described by the torrent files and magnet links at `-metainfoDir`. Data for read requests is fetched only as required from the torrent network, and stored at `-downloadDir`.
