Generating prompt to input values for a console application.

This is how you can use AutoSpectre .

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="AutoSpectre" Version="0.8.1" />
    <PackageReference Include="AutoSpectre.SourceGeneration" Version="0.8.1" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using ReadData;
Console.WriteLine("Hello,World!");

IReadPersonSpectreFactory factory = new ReadPersonSpectreFactory();
var person = factory.Get();
//Console.WriteLine($"Hello,{person.FirstName} {person.LastName}!");
person.SpectreDump();

using AutoSpectre;

namespace ReadData;
[AutoSpectreForm()]
public class ReadPerson
{

    [TextPrompt(Title = "Enter first name",DefaultValueStyle = "bold",
        DefaultValueSource = nameof(FirstNameDefaultValue))]
    public string? FirstName { get; set; }
    public readonly string? FirstNameDefaultValue = "Andrei";

    [TextPrompt(PromptStyle = "green bold")]
    public string? LastName { get; set; }
    public readonly string? LastNameDefaultValue = "Ignat";


}

The code that is generated is
