kirun-py 3.3.3

Python Runtime for Kinetic Instructions

kirun-py

Python runtime for KIRun — the Kinetic Instructions execution engine used by the Modlix no-code/low-code platform.

Installation

pip install kirun-py

Overview

KIRun executes FunctionDefinition graphs (DAGs) with:

• Expression evaluation — arithmetic, logical, string, ternary operators
• Schema validation — JSON Schema-based type checking
• 100+ built-in functions — Math, String, Array, Object, Date, JSON, Loop, Context
• Async execution — full async/await support
• Debug support — execution tracing and performance profiling

Quick Start
