bencoding

A simple encoder/decoder for decoding and encoding data in the bencoding style

Mapping

• Bencode-integer will be converted to Erlang integers.
• Bencode-strings will be converted to Erlang binary strings.
• Bencode-list will be converted to Erlang lists.
• Bencode-dictionaries will be converted to Erlang maps. (#{})

Use

Get it via hex.pm! Just add

{deps, [bencoding]}.

to your rebar.config.

See https://hex.pm/packages/bencoding for info about the hex package.

Decoding

Use bencoding:decode/1 to decode any bencoded content.

Example: Reading a torrent file:

{ok, F} = file:read_file("test.torrent").
{ok, M, _} = bencoding:decode(F).
M.

M holds the result.

Encoding

Use bencdoing:encode/1 to encode (with M from above):

{ok, B} = bencoding:encode(M).
B.
