Obsah

Rychlý start

dotnet add package RuleEval
using RuleEval.Abstractions;
using RuleEval.Core;

var ruleSet = RuleSetBuilder
    .Create("pricing")
    .AddInput("segment")
    .AddInput("age")
    .AddRule(rule => rule
        .When("segment", ".*Perspektiva.*")
        .When("age", "INTERVAL<15;24>")
        .ThenOutput("formula", "C2/240")
        .WithPrimaryKey("id", 1))
    .Build();

var evaluator = new RuleSetEvaluator();
var result = evaluator.EvaluateFirst(
    ruleSet,
    EvaluationContext.FromPositional("7BN Perspektiva Důchod", 15m),
    new EvaluationOptions(CaptureDiagnostics: true));

Console.WriteLine(result.Status);
Console.WriteLine(result.Match?.Outputs[0].RawValue); // C2/240

Volitelná integrace s Microsoft.Extensions.DependencyInjection

using Microsoft.Extensions.DependencyInjection;
using RuleEval.DependencyInjection;

services.AddRuleEval();

EvaluationContext — pozičně nebo dle názvů

Vstupní hodnoty lze předat dvěma způsoby. Pořadí pozičních hodnot odpovídá sloupci Order definice pravidel.

// Pozičně — hodnoty ve stejném pořadí jako vstupní pole v RuleSet
var result = evaluator.EvaluateFirst(
    ruleSet,
    EvaluationContext.FromPositional("7BN Perspektiva Důchod", 15m));

// Dle názvů — nezávislé na pořadí
var result = evaluator.EvaluateFirst(
    ruleSet,
    EvaluationContext.FromNamed(new Dictionary<string, object?>
    {
        ["segment"] = "7BN Perspektiva Důchod",
        ["age"]     = 15m,
    }));

Console.WriteLine(result.Status);                        // Matched
Console.WriteLine(result.Match?.Outputs[0].RawValue);    // C2/240

Vyhodnocení z databáze

dotnet add package RuleEval.Database
dotnet add package RuleEval.Database.DependencyInjection

DB schéma vrací sloupce (Name, ColNr, Order, Type) a data (Col01, Col02, …). ColNr určuje fyzický sloupec v datové tabulce, Order určuje pořadí pro poziční vyhodnocení.

SQL Server

using RuleEval.Database;
using RuleEval.Database.DependencyInjection;

// Registrace
services.AddRuleEvalDatabase(connectionString: "...",
    columnsStoredProcedure: "[Rule].p_GetSchemaColBySchemaCode",
    rowsStoredProcedure:    "[Rule].p_GetTranslatorDataBySchemaCode");

// Vyhodnocení
var repository = serviceProvider.GetRequiredService<IRuleSetRepository>();

// Pozičně — pořadí dle sloupce Order v DB
var result = await repository.EvaluateFirstAsync(
    "Rule1Schema1",
    EvaluationContext.FromPositional("EE.*hodnota", "Ahoj.*hodnota"));

// Dle názvů — Name sloupce z DB schématu
var result = await repository.EvaluateFirstAsync(
    "Rule1Schema1",
    EvaluationContext.FromNamed(new Dictionary<string, object?>
    {
        ["Input1 Obor"] = "EE.*hodnota",
        ["Input2"]      = "Ahoj.*hodnota",
    }));

Console.WriteLine(result.Status);                        // Matched
Console.WriteLine(result.Match?.Outputs[0].RawValue);    // Vystup1

Zkratky na RuleSetRepository

// Výsledek evaluace
EvaluationResult result = await repository.EvaluateFirstAsync(key, context);

// Hodí výjimku při NoMatch / AmbiguousMatch / InvalidInput
EvaluationResult result = await repository.EvaluateFirstOrThrowAsync(key, context);

// Přímo hodnota konkrétního výstupního pole, nebo null
string? value = await repository.GetFirstOutputAsync(key, context, outputName: "Vystup x");

// Hodí výjimku, pokud výstup chybí
string value  = await repository.GetFirstOutputOrThrowAsync(key, context, outputName: "Vystup x");
