KleeneLogic

KleeneLogic is a compact, fast implementation of Kleene's strong three-valued logic (K3) for C# / .NET. It gives you True, False, and Unknown with real logic operators.

Install

dotnet add package KleeneLogic

Quick start

using KleeneLogic;

Kleene a = Kleene.True;
Kleene b = Kleene.Unknown;

var result = a & b | !a;

Why use this

  • bool? (nullable Boolean) has the right values but no operators
  • You can keep uncertainty without collapsing it to false
  • Operators are branch-free and follow K3 truth tables

Control flow semantics

Kleene defines operator true and operator false:

  • if (k) runs only when k == True
  • if (!k) runs only when k == False
  • Unknown is neither true nor false

Defaults (explicit collapse)

Kleene isAllowed = ruleResult.Default(Kleene.False);
bool canProceed = isApproved.Default(false);

Parsing

Kleene k = Kleene.Parse("unknown"); // invariant default

Accepted invariant inputs are case-insensitive true, false, unknown. Alias for unknown: maybe. Numeric forms -1, 0, 1 are also accepted. Overloads accepting an IFormatProvider enable language-specific tokens. No-culture overloads use invariant terms; English culture (en-*) uses yes, no, unknown. Invariant input tokens true, false, maybe are accepted even with an explicit non-invariant culture. Language terms are read from kleene.language-terms.json next to the assembly, with built-in fallback defaults.

JSON (System.Text.Json)

using KleeneLogic;
using KleeneLogic.Serialization;
using System.Text.Json;

var opts = new JsonSerializerOptions();
opts.Converters.Add(new KleeneJsonConverter());

var k = JsonSerializer.Deserialize<Kleene>("null", opts); // Unknown
