DEPRECATED: Use the parse-torrent package instead.

Parse a .torrent file and return an object of keys/values

Works in node and the browser (with browserify). This module is used by WebTorrent!

install

npm install parse-torrent-file

usage

var parseTorrentFile = require('parse-torrent-file')
var path = require('path')

var torrent = fs.readFileSync(path.join(__dirname, 'torrents/leaves.torrent'))
var parsed
try {
  parsed = parseTorrentFile(torrent)
} catch (e) {
  // the torrent file was corrupt
  console.error(e)
}

console.log(parsed.name) // Prints "Leaves of Grass by Walt Whitman.epub"

The parsed torrent object looks like this:

To convert a parsed torrent back into a .torrent file buffer, call parseTorrentFile.encode.

var parseTorrentFile = require('parse-torrent-file')

// parse a torrent
var parsed = parseTorrentFile(/* some buffer */)

// convert parsed torrent back to a buffer
var buf = parseTorrentFile.encode(parsed)

credit

This was originally based on read-torrent by mafintosh. It's basically a pared-down version of that, but it works in the browser (so WebTorrent can use it), doesn't have huge npm dependencies like request (saving on file size), and it has tests. Thanks for publishing good modules, mafintosh!

Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a commit status is reported on all branches. This is required by Greenkeeper because we are using your CI build statuses to figure out when to notify you about breaking changes.

Since we did not receive a CI status on the greenkeeper/initial branch, we assume that you still need to configure it.

If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with greenkeeper/.

We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.

Once you have installed CI on this repository, you’ll need to re-trigger Greenkeeper’s initial Pull Request. To do this, please delete the greenkeeper/initial branch in this repository, and then remove and re-add this repository to the Greenkeeper integration’s white list on Github. You'll find this list on your repo or organization’s settings page, under Installed GitHub Apps.
