pirn-core 0.4.0

A pipeline framework where everything is a knot.

pirn-core

The core of pirn — a pipeline framework where everything is a knot. Imports as pirn.

pirn-core carries the engine, run/manager machinery, the connector public surface (pirn.connectors.*), the shared provider bases (pirn.core.providers.*), and the sweet_tea registry plumbing. Its base install is domain-free (constraint C2): import pirn pulls no heavy backend, and core never imports a pirn_<domain> package.

Install

pip install pirn-core

Backends are optional extras (none installed by default):

pip install "pirn-core[postgres,s3,kafka]"   # pick the backends you need

Domains

The domain libraries ship as separate, independently-installable packages that each depend on pirn-core and self-register their knots under library="pirn":

Package	Imports as	Domain
pirn-signal	pirn_signal	Digital signal processing
pirn-data	pirn_data	Data engineering / analytics
pirn-ml	pirn_ml	ML engineering (depends on pirn-data)
pirn-agents	pirn_agents	LLM agents
pirn-health	pirn_health	Health / clinical
pirn-oilgas	pirn_oilgas	Oil & gas

Install a domain (it pulls pirn-core automatically):

pip install pirn-signal
