# NOB

NOB - its a source generator that allows you not to write boilerplate code in the WPF.

## Features

1. Generate property

2. Generate INotifyPropertyChanged

3. Generate ICommand

4. Generate Command (only without parameters)

## Example

Make your viewmodel a partial class, add the viewmodel attribute to the class, the property attribute to the fields, the command attribute to the methods.

```CSharp    

    [ViewModel]

    public partial class MainWindowViewModel

    {

        [Property]

        private string text1;

        [Command]

        private void ClearText1() => PropertyText1 = "";

        public MainWindowViewModel() { }

    }

```

And this is what your viewmodel will become

```CSharp    

using System;

using System.ComponentModel;

using System.Windows.Input;

using GeneratedCommand;

namespace GeneratedAttribute

{

  [AttributeUsage(AttributeTargets.Class)]

  public class ViewModelAttribute : Attribute { }

  [AttributeUsage(AttributeTargets.Field)]

  public class PropertyAttribute : Attribute { }

  [AttributeUsage(AttributeTargets.Method)]

  public class CommandAttribute : Attribute { }

}

namespace GeneratedCommand

{

  public class Command : ICommand

  {

  private readonly Action _execute;

  private readonly Func _canExecute;

  public event EventHandler CanExecuteChanged

  {

    add { CommandManager.RequerySuggested += value; }

    remove { CommandManager.RequerySuggested -= value; }

  }

  public Command(Action execute, Func canExecute = null)

    => (_execute, _canExecute) = (execute, canExecute);

  public bool CanExecute(object parameter) => true;

  public void Execute(object parameter) => _execute();

  }

}

namespace NOB.SampleProject.ViewModels

{

  public partial class MainWindowViewModel : INotifyPropertyChanged

  {

    public string PropertyText1

    {

      get => text1;

      set 

      {

        text1 = value; OnPropertyChanged(nameof(PropertyText1));

      }

    }

  private Command commandClearText1;

  public Command CommandClearText1

  {

    get => new(ClearText1);

  }

  public event PropertyChangedEventHandler PropertyChanged;

  public void OnPropertyChanged(string propertyName = null) 

  { 

    PropertyChanged?.Invoke(this, new(propertyName)); 

  }

 }

}

```
