The Qore "tibrv" module provides direct TIBCO Rendezvous support, allowing Qore programs to send and receive Rendezvous messages directly. Note that to use this software, you must have a licensed version of TIBCO Rendezvous from TIBCO, Inc (so this module depends on non-free software).
Xenograte Community Toolkit is based on Xenograte, a platform which enables users to manage and orchestrate worker processes, and easily design the flow of data shared among them. Xenograte works either on one server or across multiple servers/clouds. The Toolkit provides a CLI and other resources for building, testing, and debugging worker processes, in Ruby, on a single machine. You can then easily weave these worker processes together into powerful integrations or automations.
