RSCG – Sera.Union
 
 

Generate tagged union

This is how you can use Sera.Union .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

	<ItemGroup>
	  <PackageReference Include="Sera.Union" Version="0.7.0" />
	</ItemGroup>

</Project>

The code that you will use is

using UnionTypesDemo;

Console.WriteLine("Save or not");
var data = SaveToDatabase.Save(0);
Console.WriteLine(data.IsNotFound);
data = SaveToDatabase.Save(1);
if(data.IsOk)
{
    Console.WriteLine(data.Tag);
    Console.WriteLine(data.Ok);
}

The code that is generated is

// <auto-generated/>

RSCG – RSCG_NameGenerator
 
 

Generating unique names for assemblies

This is how you can use RSCG_NameGenerator .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

	<PropertyGroup>
	
		<OutputType>Exe</OutputType>
		<TargetFramework>net8.0</TargetFramework>
		<ImplicitUsings>enable</ImplicitUsings>
		<Nullable>enable</Nullable>
	</PropertyGroup>

	<ItemGroup>
		<PackageReference Include="RSCG_NameGenerator" Version="2024.26.8.2002" >
			<OutputItemType>Analyzer</OutputItemType>
			<ReferenceOutputAssembly>false</ReferenceOutputAssembly>
		</PackageReference>
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using Generated.TestNameGenerator;
//by just putting here
//you will not deploy the dll when you deploy the project
//name are generated in the code source
Console.WriteLine($"Name:{TheAssemblyInfo.GeneratedName}");
Console.WriteLine($"Nice:{TheAssemblyInfo.GeneratedNameNice}");
Console.WriteLine($"Small:{TheAssemblyInfo.GeneratedNameSmall}");
//if you want to generate a new name every time you run the app
//put in the csproj
//<ReferenceOutputAssembly>false</ReferenceOutputAssembly>
//but the dll will be deployed with the app
//Console.WriteLine(NameGenerator.NameGeneratorData.Generate().UniqueNameLong);

The code that is generated is

                // <auto-generated/>
                namespace Generated.TestNameGenerator
                {
                    public static class TheAssemblyInfo
                    {
                        public const string AssemblyName = "TestNameGenerator";
                        public const string GeneratedNameNice = "Sir Winston Churchill is feeling private in Naypyidaw";
                        public const string GeneratedNameSmall = "private-Sir Winston Churchill";
                        public const string GeneratedName = "private-Sir Winston Churchill-Naypyidaw";
                        
                    }
                }
