Silverfly is a versatile parsing framework that provides extensive support for building custom parsers with ease. It

supports Pratt parsing, a powerful method for parsing expressions and statements in a flexible manner.

## Features

- **Flexible Parsing**: Supports Pratt parsing for complex expression handling.

- **Extensible**: Easily extend the parser and lexer with custom rules.

- **Documentation**: Comprehensive instructions available in the wiki.

## Installation

To install Silverfly, you can use NuGet:

```bash

dotnet add package Silverfly

```

## Usage

```csharp

using Silverfly;

namespace Sample;

public class Program

{

    public static void Main(string[] args)

    {

        while (true)

        {

            Console.Write("> ");

            var input = Console.ReadLine();

            var parsed = new ExpressionGrammar().Parse(input);

            var context = new EvaluationContext();

            EvaluationListener.Listener.Listen(context, parsed.Tree);

            Console.WriteLine("> " + evaluated);

        }

    }

}

```

Silverfly uses the brilliant library from [MrKWatkins](https://github.com/MrKWatkins/Ast/) to build an AST.
