# Opal

A client library for the Gemini and Titan protocols targeting .NET Standard 2.0 and .NET 7

## Features

- Asynchronous requests

- Typed Gemtext document handling

- Event-based user input

- Configurable redirect behavior

- Optional client certificate support with creation and persistence

- Optional TOFU semantics with persistent certificate caching

- No external dependencies

## Usage

Install the Nuget package

```

Install-Package Opal -Version 1.7.6

```

Create an instance of a client and make requests

```csharp

// the default behavior is to automatically follow redirects and to persit 

// local and remote certificates to disk

var client = new OpalClient();

var response = await client.SendRequestAsync("gemini.circumlunar.space");

if (response is GemtextResponse gmi)

{

  // the response body may accessed directly...

  await using (var reader = new StreamReader(gmi.Body))

    Console.WriteLine(reader.ReadToEnd());

  

  // ... or as a collection of strongly-typed ILine objects

  foreach (var line in gmi.AsDocument())

  {

    if (line is LinkLine link)

      Console.WriteLine($"Found link to {link.Uri}");

     

    Console.WriteLine(line);

  }

}

```
