NAME

Net::BitTorrentSync - A Perl interface to the BitTorrent Sync API

VERSION

version 0.1

SYNOPSIS

use Net::BitTorrentSync;

set_config('/path/to/config_file');

add_folder('/path/to/folder');

my $folders = get_folders();

remove_folder($folders->[0]->{secret});

DESCRIPTION

BitTorrent Sync uses the BitTorrent protocol to sync files between two or more machines, or nodes (computers or mobile phones) without the need of a server. It uses "secrets", a unique hash string given for each folder that replaces the need for a tracker machine. The more nodes the network has, the faster the data will be synched between the nodes, allowing for very fast exchange rates. In addition, folders and files can be shared as read-only, or as read and write.

This is a complete wrapper of the published BitTorrent Sync API. It can be used to connect your Perl application to a running BitTorrent Sync instance, in order to perform any action such as adding, removing folders/files, querying them, setting preferences, and fetch information about the BitTorrent Sync instance.

!WARNING!

The BitTorrent Sync technology and the existing BitTorrent Sync client are not open source or free software, nor are their specs available in any shape or form other than the API. Therefore, there is no guarantee whatsoever that the communication between nodes is not being monitored by BitTorrent Inc. or by any third party, including the US Government or any Agency on behalf of the US Government.

REQUIREMENTS

In order to run these commands you must have a running instance of the BitTorrent Sync client, available for download here: http://www.bittorrent.com/sync/downloads.

No other non-perl requirements are needed.

METHODS

set_config

add_folder

Adds a folder to Sync. If a secret is not specified, it will be generated automatically. The folder will have to pre-exist on the disk and Sync will add it into a list of syncing folders. Returns '0' if no errors, error code and error message otherwise.

dir (required) - specify path to the sync folder
secret (optional) - specify folder secret
selective_sync (optional) - specify sync mode, selective - 1, all files (default) - 0

get_folders

Returns an array with folders info. If a secret is specified, will return info about the folder with this secret.

	[
	    {
			dir		 => "/path/to/dir/"
	        secret	 => "A54HDDMPN4T4BTBT7SPBWXDB7JVYZ2K6D",
	        size	 => 23762511569,
	        type	 => "read_write",
	        files	 => 3206,
	        error	 => 0,
	        indexing => 0
	    }
	]


    secret (optional) - if a secret is specified, will return info about the folder with this secret

remove_folder

Removes folder from Sync while leaving actual folder and files on disk. It will remove a folder from the Sync list of folders and does not touch any files or folders on disk. Returns '0' if no error, '1' if there’s no folder with specified secret.

secret (required) - specify folder secret

get_files

Returns list of files within the specified directory. If a directory is not specified, will return list of files and folders within the root folder. Note that the Selective Sync function is only available in the API at this time.

	[
	    {
	        name  => "images",
	        state => "created",
	        type  => "folder"
	    },
	    {
	        have_pieces  => 1,
	        name 		 => "index.html",
	        size 		 => 2726,
	        state 		 => "created",
	        total_pieces => 1,
	       	type 		 => "file",
	        download 	 => 1 # only for selective sync folders
	    }
	]


    secret (required) - must specify folder secret
    path (optional) - specify path to a subfolder of the sync folder.

set_file_prefs

Selects file for download for selective sync folders. Returns file information with applied preferences.

secret (required) - must specify folder secret
path (required) - specify path to a subfolder of the sync folder.
download (required) - specify if file should be downloaded (yes - 1, no - 0)

get_folder_peers

Returns list of peers connected to the specified folder.

	[
	    {
	       	id			=> "ARRdk5XANMb7RmQqEDfEZE-k5aI=",
	        connection 	=> "direct", # direct or relay
	        name 		=> "GT-I9500",
	        synced		=> 0, # timestamp when last sync completed
	        download 	=> 0,
	        upload 		=> 22455367417
	    }
	]


    secret (required) - must specify folder secret

get_secrets

Generates read-write, read-only and encryption read-only secrets. If ‘secret’ parameter is specified, will return secrets available for sharing under this secret. The Encryption Secret is new functionality. This is a secret for a read-only peer with encrypted content (the peer can sync files but can not see their content). One example use is if a user wanted to backup files to an untrusted, unsecure, or public location. This is set to disabled by default for all users but included in the API.

	{
	    read_only  => "ECK2S6MDDD7EOKKJZOQNOWDTJBEEUKGME",
	    read_write => "DPFABC4IZX33WBDRXRPPCVYA353WSC3Q6",
	    encryption => "G3PNU7KTYM63VNQZFPP3Q3GAMTPRWDEZ"
	}


    secret (required) - must specify folder secret
    type (optional) - if type=encrypted, generate secret with support of encrypted peer

	NOTE: there seems to be some contradiction in the documentation wrt to secret being required.

get_folder_prefs

Returns preferences for the specified sync folder.

	{
	    search_lan 		 => 1,
	    use_dht 		 => 0,
