The RABX specification is a [Perl module](https://github.com/mysociety/commonlib/blob/master/perllib/RABX.pm) by [mySociety](https://www.mysociety.org/).

## Usage

```ruby
require 'rabx/message'
```

Dump a RABX message:

```ruby
RABX::Message.dump('R', 'RPC.method', ['argument', 3])
# => "R1:0,10:RPC.method,L1:2,T8:argument,I1:3,"
RABX::Message.dump('S', {name: 'foo', email: 'foo@example.com'})
# => "S1:0,A1:2,T4:name,T3:foo,T5:email,T15:foo@example.com,"
RABX::Message.dump('E', 404, 'Not Found')
# => "E1:0,3:404,9:Not Found,N"
```

Load a RABX message:

```ruby
message = RABX::Message.load("R1:0,10:RPC.method,L1:2,T8:argument,I1:3,")
message.type # "R"
message.method # "RPC.method"
message.argumetns # ["argument", 3]

message = RABX::Message.load("S1:0,A1:2,T4:name,T3:foo,T5:email,T15:foo@example.com,")
message.type # "S"
message.value # {"name"=>"foo", "email"=>"foo@example.com"}

message = RABX::Message.load("E1:0,3:404,9:Not Found,N")
message.type # "E"
message.code # "404"
message.text # "Not Found"
message.extra # nil
```

See the [documentation](http://www.rubydoc.info/gems/rabx-message) to see how to work with `RABX::Message` instances.
