NFormula

NFormula is a lightweight .NET formula expression engine that allows you to parse and evaluate dynamic expressions written by end users. It supports custom variables ({{...}}), pluggable functions and operators, and is built with extensibility and performance in mind.

✨ Features

  • Supports arithmetic, logical, and comparison operators
  • Allows user-defined functions and operators
  • Manual tokenizer (no regex dependency)
  • Parses variables like {{variableName}}
  • Perfect for rule engines, custom calculations, and expression-based workflows

📦 Installation

dotnet add package NFormula

🚀 Quick Start

var parser = new NFormularParserBuilder()
    .AddDefault()
    .Build();

var expr = parser.Parse("1 + 2 * 3");
var result = expr.Evaluate(); // result = 7

With variable context:

var context = new DictionaryEvaluationContext(new Dictionary<string, object>
{
    { "x", 10 },
    { "y", 5 }
});

var expr = parser.Parse("{{x}} - {{y}}");
var result = expr.Evaluate(context); // result = 5

🧩 Extensibility

You can register your own:

  • IFunction implementations
  • IBinaryOperator or IUnaryOperator implementations

This allows you to fully customize your formula domain.

📚 Use Cases

  • Business rule engines
  • Dynamic forms or workflow conditions
  • Spreadsheet-like formula evaluation
  • Lightweight expression system
