Latest commit 1de6196 @daronco daronco Allow newer versions of BBB using the highest version we support
If a user sets a new version of BBB we don't support yet, now the gem will
use the highest version supported.
This will be useful in most of the cases, since the changes in BBB's API
are usually backwards compatible.
Still raise exceptions if trying to use a version lower than the lowest
supported tough.

This is a ruby gem that provides access to the API of BigBlueButton. See the documentation of the API here.

It enables a ruby application to interact with BigBlueButton by calling ruby methods instead of HTTP requests, making it a lot easier to interact with BigBlueButton. It also formats the responses to a ruby-friendly format and includes helper classes to deal with more complicated API calls, such as the pre-upload of slides.

A few features it has:

  • Provides methods to perform all API calls and get the responses;

  • Converts the XML responses to ruby hashes, that are easier to work with;

  • Converts the string values returned to native ruby types. For instance:

    • Dates are converted DateTime objects (e.g. “Thu Sep 01 17:51:42 UTC 2011”);

    • Response codes are converted to boolean (e.g. “SUCCESS” becomes true);

  • Deals with errors (e.g. timeouts) throwing BigBlueButtonException exceptions;

  • Support to multiple BigBlueButton API versions (see below).
