JSON Parsing a File of Standalone Objects in Ruby

I have a JSON file with discrete objects that are not enclosed in another composite object (e.g. an array). The reason for this is that I don't want to rely on the assumption that they will all fit into memory.

In other words, I'd like to iterate over them, reading, parsing, and processing them one at a time.

In YAML I can do this using YAML.load_documents. Is there such a thing in (Ruby) JSON?

Thanks, Keith

So basically you want a streaming parser for JSON.

Try yajl-ruby, a gem with ruby bindings to the Yajl JSON streaming parser library, or JSON::Stream a streaming pure-ruby JSON parser.
