# `Geekeey.Process`

Process is a .NET library for interacting with external command-line interfaces. It provides a convenient model for
launching processes, redirecting input and output streams, awaiting completion, handling cancellation, and more.

## Features

- **Input and Output redirection:** flexible piping model, that allows to redirect the process's streams.
- **Immutability:** The `Command` object is immutable, ensuring thread safely and allowing sharing of a base
  configuration.

## Getting Started

### Install the NuGet package:

```shell
dotnet add package Geekeey.Process
```

You may need to add our NuGet feed to your `nuget.config` this can be done by running the following command:

```shell
dotnet nuget add source -n geekeey https://code.geekeey.de/api/packages/geekeey/nuget/index.json
```

### Usage

```csharp
public static Task<int> Main()
{
  var stdout = new StringBuilder();
  var cmd = new Command("git").WithArguments(["config", "--get", "user.name"]) | stdout;
  await cmd.ExecuteAsync();
  Console.WriteLine(stdout.ToString());
  return 0;
}
```

```csharp
public static Task<int> Main()
{
  var stdout = new StringBuilder();
