Transmission RPC Ruby

Transmission RPC Ruby is a Ruby library to communicate with Transmission RPC (bittorrent client). This library is based on this spec and currently supports RPC versions >= 14

Installation

gem install transmission-rpc-ruby

Then require it

require 'transmission'

Getting started

To get started with this gem you need to decide if you are using this library to connect to one or multiple transmission daemons. Both is possible

Single connection

Just set up a single configuration with will be used throughout any library calls

Transmission::Config.set host: 'some.host', port: 9091, ssl: false, credentials: {username: 'transmission', password: '********'}

torrents = Transmission::Model::Torrent.all

Multiple connections

Introducing the Transmission::RPC class, which represent all the raw rpc connection requests.

rpc = Transmission::RPC.new host: 'some.host', port: 9091, ssl: false, credentials: {username: 'transmission', password: '********'}

torrents = Transmission::Model::Torrent.all connector: rpc

This Object can be passed to any of the Transmission::Model classes. Examples are shown below.

Configuration options

Both Transmission::Config and Transmission::RPC take the same arguments, these are the default settings:

{
  host: 'localhost',
  port: 9091
  path: '/transmission/rpc',
  ssl: false,
  credentials: {username: 'transmission', password: '********'},
  session_id: ''
}

Torrents

To work with torrents you need use the Transmission::Model::Torrent class

Get all torrents

torrents = Transmission::Model::Torrent.all

If only a few fields are required

torrents = Transmission::Model::Torrent.all fields: ['id']

Find a torrent

id = 1
torrent = Transmission::Model::Torrent.find id

If only a few fields are required

torrent = Transmission::Model::Torrent.find id, fields: ['id']

Add a torrent

filename = 'http://example.com/torrent.torrent'
torrent = Transmission::Model::Torrent.add arguments: {filename: filename}

NOTE: you can also specify a magnet link instead

You can also ask for certain fields too

filename = 'http://example.com/torrent.torrent'
torrent = Transmission::Model::Torrent.add arguments: {filename: filename}, fields: ['id']

Or use an RPC connector instance

rpc = Transmission::RPC.new host: 'some.host', port: 9091, ssl: false, credentials: {username: 'transmission', password: '********'}

filename = 'http://example.com/torrent.torrent'
torrent = Transmission::Model::Torrent.add arguments: {filename: filename}, fields: ['id'], connector: rpc

Torrent instance methods

id = 1
torrent = Transmission::Model::Torrent.find(id)

torrent.start!
torrent.start_now!
torrent.stop!
torrent.verify!
torrent.re_announce!

torrent.move_up!
torrent.move_down!
torrent.move_top!
torrent.move_bottom!

torrent.finished?
# => true

torrent.to_json
# => {"id"=>132, "name"=>"Torrent Name", ....}

You can access the torrent accessors & mutators via instance methods too

# uploadLimited
torrent.upload_limited
torrent.upload_limited = true

torrent.save!

The save! method will update the torrent on your remote transmission daemon.

To find all the torrent accessors & mutators visit spec

Change torrent location

id = 1
torrent = Transmission::Model::Torrent.find(id)

# Copies torrent to new location
torrent.set_location '/some/new/path'

# Moves torrent to new location
torrent.set_location '/some/new/path', true

Start & Stop all torrents

You can also start and stop all torrents

Transmission::Model::Torrent.start_all!

Transmission::Model::Torrent.stop_all!

Dealing with multiple torrents

If you want to change multiple torrents at once:

ids = [1, 2, 3]
torrents = Transmission::Model::Torrent.find ids

This will return a Transmission::Model::Torrent instance which takes the same methods as described before.

torrents.start!
torrents.stop!
# ...

torrents.to_json
# => [{"id"=>132, "name"=>"Torrent Name", ....}, {...}]

# uploadLimited
torrents.upload_limited = false
torrents.save!

This will change uploadLimited for all torrents with ids 1, 2 & 3.

NOTE: If using Transmission::Model::Torrent you will only be able to modify their mutators.

To find out if a torrent instance contains multiple torrents

torrents.is_multi?
# => true

Session

To find out more about the current session use the Transmission::Model::Session class.

Get session

session = Transmission::Model::Session.get

If only a few fields are required

session = Transmission::Model::Session.get fields: ['version']

If used with a connector

options = {}
rpc = Transmission::RPC.new options

session = Transmission::Model::Session.get connector: rpc

Change session

Like the Transmission::Model::Torrent class, you change some session properties

session = Transmission::Model::Session.get

# alt-speed-enabled
session.alt_speed_enabled
session.alt_speed_enabled = true

session.save!

To find all the session accessors & mutators visit spec

Session Stats

You can also retrieve some session stats by using the Transmission::Model::SessionStats class

session_stats = Transmission::Model::SessionStats.get

# activeTorrentCount
session_stats.active_torrent_count

For session stats there are no mutators. To find out more about the accessors visit the spec

RPC Connector

If it is not desired to use any of the Transmission::Model classes you can use the RPC connector

Examples

rpc = Transmission::RPC.new host: 'some.host', port: 9091, ssl: false, credentials: {username: 'transmission', password: '********'}

session_body = rpc.get_session

ids = [1, 2, 3]

torrent_bodies = rpc.get_torrent ids
rpc.start_torrent ids
