Torrentfile

Library for managing Torrent files and magnet links

Parse and create torrent files

Include a couple of CLI tools as an example of use

Usage

Reading Torrent Files

You can read a file from disk of from memory

tFile, err := Open("path/example.torrent") // Open torrent file from path
tFile, err := FromMem(buffer) // Open torrent file from memory 

TFile is a struct of type TorrentFile containing the parsed fields

Creating Torrent Files

 buffer, err := NewTorrentFile(&config, "path/file.torrent")

Create a new torrent file based on the provided config. Second argument can be a single file or a folder for a multi-file torrents.

If a folder is specified as a second argument, library will traverse the whole folder structure adding every file to the torrent file

You can specify the current fields in config:

type TConfig struct {
    Announce     string
    AnnounceList [][]string
    Encoding     string
    Comment      string
    CreatedBy    string
    UrlList      []string
    PieceSize    int
    Md5          bool
    Private      bool
}

Piece Size is 32Kb by default. Some trackers will need some specific setting here depending on the size of the torrent.file

Magnet Links

Library allows to create and read Magnet links

    func ParseMagnetURI(uri string) (*MagnetLink, error) // Returns a struct with the parsed Magnet Link
    func NewMagnetURI(magnet *MagnetLink) string // Returns a string with the generted Magnet URI

Fields supported by the library:

• xt (Exact Topic)
• dn (Display Name)
• tr (Address Tracker)
• xl (Exact Length)
• kt (Keyword Topic)
• as (Acceptable Sources)
• xs (Exact Sources)
• mt (Manifest Topic)

Note: Most of the BitTorrent clients accept only a single "mt" field. But as this is not strictly defined I decided to allow multiple manifest topics. If you just want to support 1 read the first element of the array
