Libby

Libby is a tiny messaging library built on Bamboo with pluggable transports (ZMQ or RabbitMQ). It gives you:

• Keywords — typed, named values (show / modify) served over RPC, with a registry, auto-generated keys.list / keys.describe / keys.read services, and CLI coercion.

• LibbyDaemon — a base class for peers: lifecycle, RPC handlers, and pub/sub, in a few overrides.

• Client — a long-lived, in-process handle for reading and writing keywords from scripts, and for blocking on a keyword condition with wait_for (libby’s ktl.waitFor).

• Keygrabber: a daemon that polls keywords from other peers and writes them to a time-series database for dashboarding.

• libby CLI — a command-line front end for keyword peers (show / modify / list / describe / waitfor), with TAB completion and wildcard listing to find which peers are up.
