## Overview

Cottle is an open-source (MIT) templating engine for C# .NET designed to be
light (no external dependency & simple API), fast (see
[benchmark](https://r3c.github.io/cottle/benchmark.html)) and extensible (see
[advanced features](https://cottle.readthedocs.io/en/stable/page/05-advanced.html)).

## Sample

```sh
Hello, {name}!

{if len(messages) > 0:
    You have {len(messages)} new message{if len(messages) > 1:s} in your mailbox!
|else:
    You have no new message.
}
```

```cs
var document = Document.CreateDefault(template).DocumentOrThrow;

return document.Render(Context.CreateBuiltin(new Dictionary<Value, Value>
{
    ["messages"] = GetMessages(),
    ["name"] = "JC Denton"
}));
```
