An erlang implementation of Bittorrent’s bencode format. See: http://bittorrent.org/beps/bep_0003.html
- There is no depth limit.
- No error handing. Invalid input will cause a crash.
This library can be built with rebar3: $ rebar3 compile
or you can include it in your projects as a dependency in rebar.config:
{deps, [%% ... Other dependencies
{bencode, {git, "https://github.com/hyperimpose/bencode.git", {branch, "master"}}}]}.There are two functions exported by bencode: decode/1 and encode/1.
%% Encode an erlang term:%%%% This function will return the following bencoded binary:%% <<"d4:testi123ee">>bencode:encode(#{<<"test"=>123>>}).
%% Decode an erlang term:%%%% This function will return an erlang dictionary:%% #{<<"test" => 123>>}bencode:decode(<<"d4:testi123ee">>).
%% See the next section for the supported terms and their equivalents.The bencoded values map to Erlang terms as follows:
| Bencode | Erlang |
|---|---|
| dictionaries | map() #{} (If there are duplicate keys the last one is kept) |
| lists | list() [] (Including strings/iolists etc.) |
| integers | integer() |
| strings | binary() |
Atoms or other terms are not supported.
