Karpfen Connectors

Starter templates for connecting to a karpfen runtime server via its HTTP + WebSocket API.

Starter templates

Directory	Language
python_starter/	Python
java_starter/	Java
scala_starter/	Scala

Each starter contains a KarpfenConnector client class and a Main/main.py entry point that runs a minimal lightbulb demo against a local Karpfen server (127.0.0.1:8080).

Example models

example_models/ holds three DSL files that are loaded by all starters:

File	Purpose
domain.kmeta	Metamodel — defines Lightbulb and Room types
world.kmodel	World model — instantiates a room with a lightbulb
lightbulb.kstates	State machine — drives the lightbulb through light_off → movement_detected → light_on states

Running a starter

Start a Karpfen runtime server first, then from the relevant directory, execute the run.sh files or the respective main classes directly
