Everything is imported into your namespace.


You get the two Bencode-related functions: bencode and bdecode. For more on Bencoding, see the BitTorrent Protocol documentation.


Imports the tracker response-related functions compact and uncompact.


bencode ( ARGS )

Expects a single value (basic scalar, array reference, or hash reference) and returns a single string.

Bencoding is the BitTorrent protocol's basic serialization and data organization format. The specification supports integers, lists (arrays), dictionaries (hashes), and byte strings.

bdecode ( STRING )

Expects a bencoded string. The return value depends on the type of data contained in the string.

compact ( LIST )

Compacts a list of IPv4:port strings into a single string.

A compact peer is 6 bytes; the first four bytes are the host (in network byte order), the last two bytes are the port (again, in network byte order).

uncompact ( STRING )

Inflates a compacted string of peers and returns a list of IPv4:port strings.
