Xdg.Net is a ***small*** (the .dll is only 11 KB), [***fast***](./src/Xdg.Benchmarks/README.md) and ***portable*** (Completely supports .NET Standard 2.0 and even NativeAOT!) .NET implementation of the [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) and XDG user directories for Windows, MacOS and Linux/FreeBSD.

## Installation
Use [NuGet](http://docs.nuget.org/docs/start-here/installing-nuge) to install [Xdg.Directories](thttps://www.nuget.org/packages/Xdg.Directories).

From the .NET CLI:

```bash
dotnet add package Xdg.Directories
```

or from Visual Studio's package manager:

```pwsh
Install-Package Xdg.Directories
```

## Usage

### Base Directories, C#

```csharp
using System;
using Xdg.Directories;

// Prints /home/$USER/.local/share
Console.Writeline(BaseDirectory.DataHome);

// Prints /home/$USER/.cache
Console.Writeline(BaseDirectory.CacheHome)
```

### User Directories, F#

```fsharp
open Xdg.Directories

// Prints /home/$USER/Documents
printfn "%s" UserDirectory.DesktopDir
```

## Default Locations

If any of the respective XDG environment are specified, the variable will always be returned.
Otherwise, the value depends on the operating system.

Inspiration is taken from the [Go implementation](https://github.com/adrg/xdg) for Windows and MacOS directories.
