BERT

A BERT (Binary ERlang Term) serialization library for Ruby. It can encode Ruby objects into BERT format and decode BERT binaries into Ruby objects.

See the BERT specification at bert-rpc.org.

Instances of the following Ruby classes will be automatically converted to the proper simple BERT type:

  • Fixnum
  • Float
  • Symbol
  • Array
  • String

Instances of the following Ruby classes will be automatically converted to the proper complex BERT type:

  • NilClass
  • TrueClass
  • FalseClass
  • Hash
  • Time
  • Regexp

To designate tuples, simply prefix an Array literal with a t or use the BERT::Tuple class:

t[:foo, [1, 2, 3]]
BERT::Tuple[:foo, [1, 2, 3]]

Both of these will be converted to (in Erlang syntax):

{foo, [1, 2, 3]}

Installation

gem install bert -s http://gemcutter.org

Usage

require 'bert'

bert = BERT.encode(t[:user, {:name => 'TPW', :nick => 'mojombo'}])
# => "\203h\002d\000\004userh\003d\000\004bertd\000\004dictl\000\000\
      000\002h\002d\000\004namem\000\000\000\003TPWh\002d\000\004nickm\
      000\000\000\amojomboj"

BERT.decode(bert)
# => t[:user, {:name=>"TPW", :nick=>"mojombo"}]

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
