torrent

PkgGoDev

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 downstream services since late 2014. The implementation was specifically created to explore Go's concurrency capabilities, and to include the ability to stream data directly from the BitTorrent network. To this end it supports seeking, readaheads and other features exposing torrents and their files with the various Go idiomatic io package interfaces. This is also demonstrated through torrentfs.

There is support for protocol encryption, DHT, PEX, uTP, and various extensions. There are several data storage backends provided: blob, file, bolt, mmap, and sqlite, to name a few. You can write your own to store data for example on S3, or in a database.

Some noteworthy package dependencies that can be used for other purposes include:

Installation

Install the library package with go get github.com/anacrolix/torrent, or the provided cmds with go install github.com/anacrolix/torrent/cmd/...@latest.

Library examples

There are some small examples in the package documentation.

Mentions

Downstream projects

There are several web-frontends and Android clients among the known public projects:

Help

Communication about the project is primarily through Discussions and the issue tracker.

Command packages

Here I'll describe what some of the packages in ./cmd do. Install them with go get github.com/anacrolix/torrent/cmd/....

torrent

Downloads torrents from the command-line.

torrentfs

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.

$ mkdir mnt torrents
$ torrentfs -mountDir=mnt -metainfoDir=torrents &
$ cd torrents
$ wget http://releases.ubuntu.com/14.04.2/ubuntu-14.04.2-desktop-amd64.iso.torrent

torrent-magnet

Creates a magnet link from a torrent file. Note the extracted trackers, display name, and info hash.
