Example simple usage

using Config.Net;
using TakasakiStudio.Lina.AutoDependencyInjection;
using TakasakiStudio.Lina.AutoDependencyInjection.Attributes;
using TakasakiStudio.Lina.Utils.LoaderConfig;
using Microsoft.Extensions.DependencyInjection;

var serviceCollection = new ServiceCollection();

serviceCollection.AddLoaderConfig<IAppConfig>();
serviceCollection.AddAutoDependencyInjection<Program>();

var services = serviceCollection.BuildServiceProvider();

services.GetRequiredService<IFooService>().PrintAppName();

public interface IFooService 
{
    public void PrintAppName();
}

[Service<IFooService>]
public class FooService : IFooService
{
    private readonly IAppConfig _appConfig;
    
    public FooService(IAppConfig appConfig)
    {
        _appConfig = appConfig;
    }
    
    public void PrintAppName()
    {
        Console.WriteLine(_appConfig.AppName);
    }
}

public interface IAppConfig 
{
    [Option(DefaultValue = "Test")]
    public string AppName { get; }
}

Config example usage

using Config.Net;
using TakasakiStudio.Lina.Utils.LoaderConfig;
using Microsoft.Extensions.DependencyInjection;

var serviceCollection = new ServiceCollection();

var config = serviceCollection.AddLoaderConfig<IAppConfig>();

Console.WriteLine(config.AppName); // instant use

var services = serviceCollection.BuildServiceProvider();

Console.WriteLine(services.GetRequiredService<IAppConfig>().AppName); // DI usage

public interface IAppConfig 
{
    [Option(DefaultValue = "Test")]
    public string AppName { get; }
}

Database example usage

using Config.Net;
using TakasakiStudio.Lina.Database;
using TakasakiStudio.Lina.Database.Models;
using TakasakiStudio.Lina.Utils.LoaderConfig;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Metadata.Builders;
using Microsoft.Extensions.DependencyInjection;

var serviceCollection = new ServiceCollection();

var config = serviceCollection.AddLoaderConfig<IAppConfig>();
serviceCollection.AddLinaDbContext<Program>((builder, assembly) =>
    builder.UseMySql(config.DatabaseUrl, ServerVersion.AutoDetect(config.DatabaseUrl),
        optionsBuilder => optionsBuilder.MigrationsAssembly(assembly)));

public interface IAppConfig 
{
    [Option(DefaultValue = "Server=localhost;Database=test;User Id=root;Password=root;")]
    public string DatabaseUrl { get; }
}

public class User : BaseEntity<int>
{
    public string Name { get; set; } = string.Empty;
}

public class UserConfiguration : IEntityTypeConfiguration<User>
{
    public void Configure(EntityTypeBuilder<User> builder)
    {
        builder.ToTable("Users");
        builder.HasKey(x => x.Id);
        builder.Property(x => x.Name).IsRequired();
    }
}

Validation example usage

using FluentValidation;
using TakasakiStudio.Lina.Common;
using TakasakiStudio.Lina.Common.Extensions;
using TakasakiStudio.Lina.Database.Models;

var user = new User()
{
    Name = "",
    Cpf = "",
    Cnpj = "",
};

if (!await user.IsValid())
{
    Console.WriteLine("invalid");
}

user.Name = "Foo";
user.Cpf = "349.306.930-80";
user.Cnpj = "82.099.001/0001-08";

await user.Validate();

Console.WriteLine("Valid");

public class User : BaseValidated<User>
{
    public required string Name { get; set; }
    public required string Cpf { get; set; }
    public required string Cnpj { get; set; }
    
    protected override void SetupValidator(LinaAbstractValidator<User> rules)
    {
        rules.RuleFor(x => x.Name).NotEmpty();
        rules.RuleFor(x => x.Cpf).ValidCpf();
        rules.RuleFor(x => x.Cnpj).ValidCnpj();
    }
}
