bert

An updated Erlang BERT encode/decoder, based on Tom Preston-Werner’s bert.erl. This library uses maps instead of dicts, so requires Erlang/OTP R17 and higher.

See BERT RPC specification for the specs.

Requirements

• Erlang R17+
• rebar3

Build

$ rebar3 compile

Test

$ rebar3 eunit

Usage

Encode a term:

Term = #{key => [{some, "tuple"}, {true, 42}]},
bert:encode(Term).
> <<131,104,3,100,0,4,98,101,114,116,100,0,4,100,105,99,116,
  108,0,0,0,1,104,2,100,0,3,107,101,...>>

Decode a binary:

Bin = <<131,104,3,100,0,4,98,101,114,116,100,0,4,100,105,99,116,108,0,0,0,1,104,2,
        100,0,3,107,101,121,108,0,0,0,2,104,2,100,0,4,115,111,109,101,107,0,5,116,
        117,112,108,101,104,2,104,2,100,0,4,98,101,114,116,100,0,4,116,114,117,101,
        97,42,106,106>>,
bert:decode(Bin).
> #{key => [{some, "tuple"}, {true, 42}]}
