Description:

libtc 1.3.4

This is a library to interface with a variety of torrent clients,
abstracting away the need to understand a specific client api.

Requirements

Python 3.6 or higher

Installation
pip install libtc

Features
Clients:

rtorrent
Deluge
Transmission
qBittorrent
LilTorrent (local-to-remote interface for other clients)

Methods:

List torrents
Stop/start torrents
Add/remove torrents
Retrieve the actual .torrent file

Other:

Verify local content exist
Discover client config to autoconfigure clients
Move torrents between clients

Commandline interface
The commandline interface allows for basic operations on torrents:
# See available commands
libtc --help

# See help for individual command
libtc "transmission+http://127.0.0.1:9091/transmission/rpc?session_path=%7E/.config/transmission" list --help

# Execute a command
libtc "transmission+http://127.0.0.1:9091/transmission/rpc?session_path=%7E/.config/transmission" list

# Move torrent with infohash da39a3ee5e6b4b0d3255bfef95601890afd80709 from transmission to deluge
libtc "transmission+http://127.0.0.1:9091/transmission/rpc?session_path=%7E/.config/transmission" move \
"da39a3ee5e6b4b0d3255bfef95601890afd80709" \
"deluge://localclient:da39a3ee5e6b4b0d3255bfef95601890afd80709@127.0.0.1:58846?session_path=%7E/.config/deluge"

Session path & fetching torrents
This library can find and use the actual torrent files but this is generally not possible to the APIs.
Therefore it must know where the torrents are stored locally.
These folders must contain the actual .torrent files.
A list of relative torrent paths can be found here:

Deluge
<session_path>/state/

qBittorrent
<session_path>/data/BT_backup/

rtorrent
<session_path>/

Transmission
<session_path>/torrents/

An example could be transmission configured with session_path=/tmp/transmission/ then the actual torrent files would
be store in /tmp/transmission/torrents/.
These are subject to change depending on how it really works out with different client versions.

URL Syntax
The query part of urls are generally optional

Deluge
Syntax: deluge://<username>:<password>@<hostname_or_ip>:<port>?session_path=<path_to_session>
Example: deluge://localclient:da39a3ee5e6b4b0d3255bfef95601890afd80709@127.0.0.1:58846?session_path=%7E/.config/deluge

LilTorrent
Multiple path mappings can be added, they are joined by a ; - apikey is mandatory.
Syntax: liltorrent+<protocol>://<hostname_or_ip>:<port>?apikey=<apikey>&path_mapping=<rewritten_from_path>:<rewritten_to_path>;<another_rewritten_from_path>:<another_rewritten_to_path>
Example: liltorrent+http://localhost:10977?apikey=secret&path_mapping=/a/%3A/b/%3B/s/t/%3A/f/
This example changes /a/horse.gif to /b/horse.gif

qBittorrent
Syntax: qbittorrent+<protocol>://<username>:<password>@<hostname_or_ip>:<port>?session_path=<path_to_session>
Example: qbittorrent+http://admin:adminadmin@localhost:8080?session_path=%7E/.config/qBittorrent

rtorrent
Syntax: rtorrent+<protocol>://<path_or_hostname>:<optional_port>?session_path=<path_to_session>&torrent_temp_path=<path_to_accessible_tmp>
Example: rtorrent+scgi:///path/to/scgi.socket?session_path=%7E/.rtorrent/&torrent_temp_path=%7E/.rtorrent/tmp-libtc
Example: rtorrent+scgi://127.0.0.1:5000?session_path=%7E/.rtorrent/&torrent_temp_path=%7E/.rtorrent/tmp-libtc
Example: rtorrent+http://127.0.0.1:8000/SCGI?session_path=%7E/.rtorrent/&torrent_temp_path=%7E/.rtorrent/tmp-libtc

Transmission
Syntax: transmission+<protocol>://<hostname>:<port>?session_path=<path_to_session>
Example: transmission+http://127.0.0.1:9091/transmission/rpc?session_path=%7E/.config/transmission

LilTorrent usage
This layer can work as an abstraction layer between local clients in different environments,
e.g. in a docker container.
pip install libtc[liltorrent]

LILTORRENT_APIKEY=secretapikey LILTORRENT_CLIENT=rtorrent:///path/to/scgi.socket liltorrent

LILTORRENT_APIKEY is the apikey that the server is accessible through
LILTORRENT_CLIENT is a client URL

Config file syntax
These examples use .toml format, while the actual parsing logic is agnostic to on-disk format, it’s the recommended one.
The display_name is the name shown when client is used. If it is not set, then the config file key is used,
e.g. [clients.another-transmission] is called another-transmission if no display_name is set.
The URL config as described above can also be used and is seen in the last example as deluge-url.
Each key must be unique, e.g. you cannot have two clients with the same key, e.g. two [clients.the-transmission]
[clients]

[clients.deluge]
display_name = "A Deluge"
client_type = "deluge"
host = "127.0.0.1"
port = 58846
username = "localclient"
password = "secretpassword"
session_path = "~/.config/deluge/"

[clients.the-transmission]
display_name = "Some transmission"
client_type = "transmission"
url = "http://127.0.0.1:9091/transmission/rpc"
session_path = "~/.config/transmission-daemon/"

[clients.another-transmission]
display_name = "Horse transmission"
client_type = "transmission"
url = "http://127.0.0.1:9092/transmission/rpc"
session_path = "~/.config/transmission-daemon2/"

[clients.rtorrent]
display_name = "rtorrent"
client_type = "rtorrent"
url = "scgi://127.0.0.1:5000"
session_path = "~/.rtorrent/"

[clients.another-qbittorrent]
display_name = "qBittorrent 1"
client_type = "qbittorrent"
url = "http://localhost:8080/"
username = "admin"
password = "adminadmin"
session_path = "~/.config/qbittorrent/"

# This is an example of using the url syntax
[clients.deluge-url]
display_name = "Deluge url"
client_url = "deluge://localclient:da39a3ee5e6b4b0d3255bfef95601890afd80709@127.0.0.1:58846?session_path=%7E/.config/deluge"

url = "scgi://127.0.0.1:5000"
session_path = "~/.rtorrent/"
label = "alabel"

[clients.deluge-with-label]
display_name = "A Deluge"
client_type = "deluge"
host = "127.0.0.1"
port = 58846
