Rulewright.Core

Foundation package for Rulewright: the immutable domain model a rule is made of, plus the result and trace types an evaluation produces.

Zero dependencies.

Install

dotnet add package Rulewright.Core

You almost certainly want Rulewright instead — it includes this package. Install Rulewright.Core directly only when you are writing something that plugs into Rulewright and does not need the rest of it: a rule generator, an analyzer, or a custom function library.

What is in it

The rule model — RuleSet, Rule, and the condition tree: ConditionNode with its two shapes, ConditionGroup (AND/OR/NOT over children) and ConditionLeaf (a field path or computed expression, a ConditionOperator, and a constant). Everything is immutable after construction and validated in the constructor.

using Rulewright.Core;

var rule = new Rule(
    "adults-only",
    new ConditionLeaf("Customer.Age", ConditionOperator.GreaterThanOrEqual, 18),
    new[] { new RuleAction(RuleAction.SetOutputType, "Eligible", true) });

Actions — RuleAction and its four types: setOutput replaces, addToOutput sums, appendToOutput collects into a list, removeOutput deletes the key.

Value expressions — ValueExpression and its three shapes, LiteralExpression, FieldExpression, and OperatorExpression (arithmetic, concat, coalesce). Pure data: a closed operator vocabulary, never embedded code.

Results and traces — RuleEvaluationResult, FiredRule (with the RuleBranch that ran), EvaluationTrace, RuleTrace, and ConditionTraceNode, whose Passed is null for a node short-circuiting skipped. CompilationMode reports whether an evaluation ran compiled delegates or the interpreter, so a fallback is never silent.

Custom function contracts — IRuleFunction, IRuleFunctionMetadata, RuleFunctionDescriptor, and RuleFunctionValueKind: implement IRuleFunction to back the custom operator, and add the metadata interface so a builder UI can discover it.

Package Downloads
Rulewright.Serialization

Rulewright JSON-to-domain mapping, structural schema validation with JSON pointer errors, and canonical rule hashing. JSON parsing is abstracted behind IRuleJsonReader; no JSON library dependency.
Rulewright.Execution

Rulewright execution engine: expression-tree rule compiler, dynamic-fact interpreter fallback, thread-safe compiled delegate cache, and the RulewrightBuilder/RulewrightEngine public API.
Rulewright.Extensions.Functions

Built-in custom functions and registration/discovery helpers for Rulewright (the 'custom' operator).
Rulewright

The Rulewright rule engine — everything you need in one package: the core domain model, JSON parsing and schema validation, the expression-tree evaluation engine, the System.Text.Json adapter, and the built-in custom functions. Rules are plain JSON; evaluation is compiled expression trees. Install this unless you want to pick pieces individually.
