Pondermatic

Functional effect system-driven rules engine for Clojure/ClojureScript & Javascript

Overview

Pondermatic is a functional effect system-driven rules engine designed for use with Clojure, ClojureScript, and JavaScript. It provides a robust framework for defining and executing rules in a declarative manner. Pondermatic helps manage side effects in a predictable and composable way, making it easier to integrate with various data sources and build complex rule-based systems.

Features

• Functional effect system for managing side effects in a predictable and composable way
• Seamless integration with Clojure, ClojureScript, and JavaScript projects
• Declarative rule definitions for clear and concise rule management
• Integration with various data sources for flexible data handling

Architecture

Pondermatic's architecture consists of the following key components:

• Ruleset: Defines the rules to be executed.
• Dataset: Contains the data to be processed by the rules.
• Engine: Executes the rules on the dataset and manages the state.

Installation

Clojure/ClojureScript

Add the following dependency to your deps.edn file:

{:deps {tech.totalperspective/pondermatic {:mvn/version "1.11.10"}}}

JavaScript

Install via npm:

npm install @totalperspective/pondermatic

Usage

Clojure/ClojureScript

(ns example.core
  (:require [pondermatic.core :as p]))

(def rules
  (p/ruleset
   [{:id :example-rule
     :rule/when {:data/key ?value}
     :rule/then {:data/new-key ?value}}]))

(def data
  (p/dataset
   [{:key "value"}]))

(def engine (p/->engine "example" :reset-db? true))

(-> engine
    (p/|> {:->db rules})
    (p/|> {:->db data})
    p/stop)

JavaScript

import pondermatic from '@totalperspective/pondermatic';

// Create a new engine instance
const engine = pondermatic.createEngine('example', true);

// Define a ruleset
const rules = pondermatic.ruleset([
  {
    id: 'example-rule',
    'rule/when': { 'data/key': '?value' },
    'rule/then': { 'data/new-key': '?value' }
  }
]);

// Define a dataset
const data = pondermatic.dataset([{ key: 'value' }]);

// Load the ruleset into the engine
pondermatic.sh(engine, { '->db': rules });

// Load the dataset into the engine
pondermatic.sh(engine, { '->db': data });

// Stop the engine
pondermatic.stop(engine);
