Tiny Ini

Is a small source generator which generates methods for serializing and deserializing structs.

Serialization

[TinyIni.IniSerializable]
public struct Config
{
  public int Version = 0;
  public Display Display = new()
  {
    Height = 1080,
    Width = 1920,
    VSync = VSync.Enabled
  };

  public Graphics Graphics = new()
  {
    MSAA = 16,
    Advanced = new AdvancedGraphics
    {
      GraphicsAPI = GraphicsAPI.Vulkan
    }
  };
  public Input InputKeyboard = new()
  {
    JumpKey = 32
  };
  public Input InputGamepad = new()
  {
    JumpKey = 16
  };

  public Config() {}
}

[omitted for brevity]

public struct Graphics
{
  public byte MSAA;
  public AdvancedGraphics Advanced;
}

public struct AdvancedGraphics
{
  public GraphicsAPI GraphicsAPI;
}

public struct Display
{
  public int Width;
  public int Height;
  public VSync VSync;
}

public struct Input
{
  public byte JumpKey;
}

public enum VSync
{
  Enabled,
  Disabled,
  Adaptive
}

public enum GraphicsAPI
{
  Vulkan,
  DirectX12
}

TinyIni.Save("config.ini", in config);

_config.ini

Version=0

[Display]
Width=1920
Height=1080
VSync=Enabled

[Graphics]
MSAA=16

[Graphics/Advanced]
GraphicsAPI=Vulkan

[InputKeyboard]
JumpKey=32

[InputGamepad]
JumpKey=16

Deserialization

TinyIni.Load("config.ini", ref config);

Installation

Clone

Clone this repository into your solution directory.
git clone https://github.com/AQtun81/TinyIni

Add analyzer reference in your project

<ItemGroup>
  <ProjectReference Include="..\TinyIni\TinyIni.csproj"
                    OutputItemType="Analyzer"
                    ReferenceOutputAssembly="false"/>
</ItemGroup>

Compile your project

You won't see IntelliSense for any generated code until the project is built at least once.

Add [TinyIni.IniSerializable] attribute above any struct you wish to serialize

[TinyIni.IniSerializable]
public struct Config
{
  // ...

Use the generated Load and Save methods

// this will additionally create a new file if one isn't already present
TinyIni.Load($"config.ini", ref config);

// this will generate new fields and remove obsolete ones
TinyIni.Save($"config.ini", in config);

FAQ

Unity support

You'll have to do some additional steps in order to use Tiny Ini with Unity.

1. git clone https://github.com/AQtun81/TinyIni
2. Inside of TinyIni.csproj downgrade Microsoft.CodeAnalysis.Common and Microsoft.CodeAnalysis.CSharp to 4.3.0-3.final
3. Uncomment //#define TINY_INI_COMPATIBILITY inside of Program.cs to enable support for older versions of C#
4. Build the project for release dotnet build -c release
5. Copy the dll file to somewhere inside of your Assets folder
6. Click on the .dll file to open the Plugin Inspector window
7. Uncheck Any Platform, Editor and Standalone checkmarks, under Asset Labels create and assign a new label called RoslynAnalyzer

Refer to Unity's documentation for more details.

Godot support

Godot 4 C# projects use MSBuild so following the default instructions for C# projects will work.
Versions prior to that are not supported.
