ConfigManager Implementation Plan: Phases 7-9

For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

Goal: Complete the ConfigManager UI by implementing form ViewModels, dialogs, and polish features.

Architecture: Each settings section gets a dedicated FormViewModel that wraps the model and provides two-way binding with change tracking. Dialogs follow the AvaloniaDialogService pattern from SecureStoreManager.

Tech Stack: Avalonia 11.2, MVVM, TDD with xUnit/NSubstitute/Shouldly

Prerequisites: Phases 1-6 complete (13 tasks, all services and basic UI shell implemented)

Phase 7: Form ViewModels

Task 14: Create DataSyncFormViewModel

Files:

Files:

Modify: NEW/src/Utils/JdeScoping.ConfigManager/ViewModels/MainWindowViewModel.cs
Create: NEW/tests/JdeScoping.ConfigManager.Tests/ViewModels/MainWindowViewModelTests.cs

Step 1: Write the failing test

            .Returns(new ValidationResult());
        _validationService.ValidatePipelines(Arg.Any<PipelinesConfigModel>())
            .Returns(new ValidationResult());
    }

    [Fact]
    public void SelectingDataSyncNode_LoadsDataSyncFormViewModel()
    {
        // Arrange
        var config = new ConfigModel { DataSync = new DataSyncSection { MaxDegreeOfParallelism = 8 } };
        var sut = CreateViewModel();
        sut.LoadConfigForTesting(config, null);

        var dataSyncNode = sut.TreeNodes
            .SelectMany(n => n.Children)
            .First(n => n.SectionKey == "DataSync");

            _autoDiscoveryService,
            _dialogService,
            _logger);
    }
}

Step 2: Run test to verify it fails

Run: dotnet test NEW/tests/JdeScoping.ConfigManager.Tests/ --filter "MainWindowViewModelTests" Expected: FAIL - methods not implemented

Step 3: Update MainWindowViewModel with form selection logic

Add to MainWindowViewModel.cs:

// Add field
private readonly IDialogService _dialogService;
private readonly IFileSystem _fileSystem;

// Update constructor to include new services
public MainWindowViewModel(
    IFileSystem fileSystem,
    IConfigFileService configFileService,
    IValidationService validationService,
    IBackupService backupService,
    IAutoDiscoveryService autoDiscoveryService,
    IDialogService dialogService,
    ILogger<MainWindowViewModel> logger)
{
    _fileSystem = fileSystem;
    _configFileService = configFileService;
    _validationService = validationService;
    _backupService = backupService;
    _autoDiscoveryService = autoDiscoveryService;
    _dialogService = dialogService;
    _logger = logger;

    // ... existing command initialization
}

// Add test helper method
public void LoadConfigForTesting(ConfigModel? appSettings, PipelinesConfigModel? pipelines)
{
    _appSettings = appSettings;
    _pipelines = pipelines;
    BuildTreeNodes();
}

// Update OnSelectedNodeChanged
private void OnSelectedNodeChanged()
{
    if (_selectedNode == null || _appSettings == null)
    {
        SelectedFormViewModel = null;
        return;
    }

    SelectedFormViewModel = _selectedNode.SectionKey switch
    {
        "DataSync" => new DataSyncFormViewModel(_appSettings.DataSync, MarkAsChanged),
        "DataAccess" => new DataAccessFormViewModel(_appSettings.DataAccess, MarkAsChanged),
        "Auth" => new AuthFormViewModel(_appSettings.Auth, MarkAsChanged),
        "Ldap" => new LdapFormViewModel(_appSettings.Ldap, MarkAsChanged),
        "Search" => new SearchFormViewModel(_appSettings.Search, MarkAsChanged),
        "ExcelExport" => new ExcelExportFormViewModel(_appSettings.ExcelExport, MarkAsChanged),
        _ when _selectedNode.NodeType == TreeNodeType.Pipeline && _pipelines != null
            => _pipelines.Pipelines.TryGetValue(_selectedNode.SectionKey!, out var pipeline)
                ? new PipelineFormViewModel(_selectedNode.SectionKey!, pipeline, MarkAsChanged)
                : null,
        _ => null
    };
}

private void MarkAsChanged()
{
    HasUnsavedChanges = true;
    if (_selectedNode != null)
        _selectedNode.IsModified = true;
}

// Update OpenFolderAsync
private async Task OpenFolderAsync()
{
    var folder = await _dialogService.ShowFolderPickerAsync("Select Configuration Folder");
    if (folder != null)
    {
        await LoadConfigAsync(folder);
    }
}

Step 4: Run test to verify it passes

Run: dotnet test NEW/tests/JdeScoping.ConfigManager.Tests/ --filter "MainWindowViewModelTests" Expected: PASS

Step 5: Commit

git add NEW/src/Utils/JdeScoping.ConfigManager/
git add NEW/tests/JdeScoping.ConfigManager.Tests/
git commit -m "feat(configmanager): wire up form selection in MainWindowViewModel"

                        <NumericUpDown Value="{Binding LookbackMultiplier}" Minimum="1" Maximum="10" Increment="0.1"
                                       Background="#232A35" Foreground="#E6EDF5"/>
                    </StackPanel>
                    <StackPanel Grid.Column="1">
                        <TextBlock Text="Purge Retention (days)" Foreground="#9BA8B8" FontSize="12" Margin="0,0,0,4"/>
                        <NumericUpDown Value="{Binding PurgeRetentionDays}" Minimum="1" Maximum="365"
                                       Background="#232A35" Foreground="#E6EDF5"/>
                    </StackPanel>
                </Grid>
            </StackPanel>
        </Border>
    </StackPanel>
</UserControl>

Step 2: Create DataSyncFormView.axaml.cs

using Avalonia.Controls;

namespace JdeScoping.ConfigManager.Views.Forms;

public partial class DataSyncFormView : UserControl
{
    public DataSyncFormView()
    {
        InitializeComponent();
    }
}

Step 3: Create remaining form views following the same pattern

(Repeat for DataAccessFormView, AuthFormView, LdapFormView, SearchFormView, ExcelExportFormView, PipelineFormView - each with appropriate fields from the corresponding FormViewModel)

Step 4: Verify build

Run: dotnet build NEW/src/Utils/JdeScoping.ConfigManager/ Expected: Build succeeded

Step 5: Commit

git add NEW/src/Utils/JdeScoping.ConfigManager/Views/Forms/
git commit -m "feat(configmanager): add form views for all configuration sections"

Task 26: Add DataTemplates for Form Selection

Files:

Modify: NEW/src/Utils/JdeScoping.ConfigManager/Views/MainWindow.axaml

Step 1: Add DataTemplates to MainWindow.axaml

Add inside the Window before DockPanel:

<Window.DataTemplates>
    <DataTemplate DataType="{x:Type forms:DataSyncFormViewModel}">
        <views:DataSyncFormView/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type forms:DataAccessFormViewModel}">
        <views:DataAccessFormView/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type forms:AuthFormViewModel}">
        <views:AuthFormView/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type forms:LdapFormViewModel}">
        <views:LdapFormView/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type forms:SearchFormViewModel}">
        <views:SearchFormView/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type forms:ExcelExportFormViewModel}">
        <views:ExcelExportFormView/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type forms:PipelineFormViewModel}">
        <views:PipelineFormView/>
    </DataTemplate>
</Window.DataTemplates>

Add namespaces:

xmlns:forms="using:JdeScoping.ConfigManager.ViewModels.Forms"
xmlns:views="using:JdeScoping.ConfigManager.Views.Forms"

Step 2: Verify build

Run: dotnet build NEW/src/Utils/JdeScoping.ConfigManager/ Expected: Build succeeded

Step 3: Commit

git add NEW/src/Utils/JdeScoping.ConfigManager/Views/MainWindow.axaml
git commit -m "feat(configmanager): add DataTemplates for form view selection"

Task 27: Update App.axaml.cs with All Service Registrations

Files:

Modify: NEW/src/Utils/JdeScoping.ConfigManager/App.axaml.cs

Step 1: Update ConfigureServices

private void ConfigureServices(IServiceCollection services)
{
    // Logging
    services.AddLogging(builder => builder
        .AddConsole()
        .SetMinimumLevel(LogLevel.Debug));

    // Services
    services.AddSingleton<IFileSystem, FileSystem>();
    services.AddSingleton<IAutoDiscoveryService, AutoDiscoveryService>();
    services.AddSingleton<IBackupService, BackupService>();
    services.AddSingleton<IDiffService, DiffService>();
    services.AddSingleton<IValidationService, ValidationService>();
    services.AddScoped<IConfigFileService, ConfigFileService>();

    // Platform Services
    services.AddSingleton<IDialogService>(sp =>
        new AvaloniaDialogService(GetMainWindow));

    // ViewModels
    services.AddTransient<MainWindowViewModel>();
}

private Window? GetMainWindow()
{
    return (ApplicationLifetime as IClassicDesktopStyleApplicationLifetime)?.MainWindow;
}

Step 2: Update MainWindow creation

if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
{
    desktop.MainWindow = new Views.MainWindow
    {
        DataContext = Services.GetRequiredService<MainWindowViewModel>()
    };
}

Step 3: Verify build

Run: dotnet build NEW/src/Utils/JdeScoping.ConfigManager/ Expected: Build succeeded

Step 4: Run all tests

Run: dotnet test NEW/tests/JdeScoping.ConfigManager.Tests/ Expected: All tests pass

Step 5: Commit

git add NEW/src/Utils/JdeScoping.ConfigManager/App.axaml.cs
git commit -m "feat(configmanager): complete service registrations in App.axaml.cs"

Task 28: Final Integration Test

Step 1: Run the application

Run: dotnet run --project NEW/src/Utils/JdeScoping.ConfigManager/ Expected: Application launches with dark theme UI

Step 2: Verify tree view appears

Expected: Settings and Pipelines folders visible with section nodes

Step 3: Verify form selection works

Click on DataSync node Expected: DataSync form appears with numeric inputs

Step 4: Run full test suite

Run: dotnet test NEW/tests/JdeScoping.ConfigManager.Tests/ -v normal Expected: All tests pass

Step 5: Final commit

git add -A
git commit -m "feat(configmanager): complete Phases 7-9 implementation"
