# Npgsql Source Generators

Registering all enums one by one is tedious. Use this.

## Usage

Place `[PostgresEnum]` attribute on the enums you want to register...

```cs

namespace MyCoolApp;

[PostgresEnum]

public enum Status {

    Completed,

    InProgress,

    Started,

    Queued

}

[PostgresEnum(Name = "process_priority")]

public enum Priority {

    High,

    Medium,

    Low

}

```

...and register them

```cs

var source = new NpgsqlDataSourceBuilder(connectionString).npgSourceBuilder

    .MapPostgresEnums()

    .Build();

services.AddDbContext(options => options.UseNpgsql(source));

```

```cs

public class MyDbContext : DbContext

{

    protected override void OnModelCreating(ModelBuilder builder)

    {

        base.OnModelCreating(builder);

        builder.RegisterPostgresEnums();

    }    

}

```

> [!TIP]

> In Npgsql 9.0, you can use *just* this instead of the previous two

```cs

builder.Services.AddDbContext(options => options.UseNpgsql(

    "",

    o => o.MapPostgresEnums()));

```
