src/Consolonia.Core/Assembly.cs (1)
7-7: Consider addressing the CLS compliance TODO comment.The existing TODO comment about CLS compliance should be addressed. CLS compliance ensures better interoperability with other .NET languages.
Would you like me to help analyze the codebase for CLS compliance issues and create a GitHub issue to track this work?
src/Tools/Avalonia.PreviewHost/ViewModels/FileViewModel.cs (1)
7-10: Consider adding XML documentation.While the property names are descriptive, XML documentation would help clarify:
- The relationship between
_fullNameand_name- Expected format of the paths
- Null handling behavior
Example improvement:
+ /// <summary> + /// Represents a file in the preview system. + /// </summary> public partial class FileViewModel : ObservableObject { + /// <summary> + /// Gets or sets the full path of the file. + /// </summary> [ObservableProperty] private string? _fullName; + /// <summary> + /// Gets or sets the file name without the path. + /// </summary> [ObservableProperty] private string? _name; }src/Consolonia.Themes.TurboVision/Themes/Material/Material.axaml (1)
3-5: Add preview content to enable design-time visualization.The empty
Design.PreviewWithsection should include sample controls to help visualize the Material theme during design time.<Design.PreviewWith> + <StackPanel Spacing="20"> + <Button Content="Material Button" /> + <TextBox Text="Material TextBox" /> + </StackPanel> </Design.PreviewWith>src/Consolonia.Themes.TurboVision/Themes/Material/MaterialTheme.cs (1)
10-16: Consider if theme-specific initialization is needed.The constructors properly delegate to the base class, but consider if any Material theme-specific initialization is required, such as setting default colors or styles.
public MaterialTheme(IServiceProvider serviceProvider) : base(serviceProvider) { + // Consider initializing Material-specific resources or defaults here }src/Consolonia.Core/Drawing/PixelBufferImplementation/ColorConverter.cs (1)
17-20: Remove unnecessary null-forgiving operator in WriteJsonThe Color type is a value type, so the null-forgiving operator is unnecessary.
Apply this change:
public override void WriteJson(JsonWriter writer, Color value, JsonSerializer serializer) { - writer.WriteValue(value!.ToString()); + writer.WriteValue(value.ToString()); }src/Consolonia.Gallery/Program.cs (1)
20-28: LGTM: Well-structured configuration with proper design/runtime separationThe BuildAvaloniaApp method changes demonstrate good architectural decisions:
- Public visibility enables design-time tooling integration
- Conditional compilation properly separates design-time and runtime behaviors
- Maintains existing logging and console detection functionality
Consider documenting the different initialization paths in XML comments to help future maintainers understand the design-time vs runtime behavior.
src/Tools/Avalonia.PreviewHost/Program.cs (1)
5-5: Consider making the Program class staticSince this class only contains static members and serves as an application entry point, it should be marked as
staticto prevent instantiation and better express its intent.- internal class Program + internal static class Program🧰 Tools
🪛 GitHub Check: build
[notice] 5-5:
"[ClassNeverInstantiated.Global] Class 'Program' is never instantiated" on /home/runner/work/Consolonia/Consolonia/src/Tools/Avalonia.PreviewHost/Program.cs(5,20)src/Consolonia.Gallery/Gallery/GalleryViews/GalleryGradientBrush.axaml (1)
21-22: Remove or document the empty StackPanelThe empty StackPanel in Grid.Row="1" appears to serve no purpose. Consider either:
- Removing it if not needed
- Adding a comment explaining its intended future use
- Implementing its intended functionality now
- - <StackPanel Grid.Row="1"/>src/Consolonia.Designer/Extensions.cs (3)
9-20: Complete the XML documentationThe documentation is incomplete and missing important details:
- The
<param name="builder">tag lacks description- The
<returns>tag lacks description- There's an incomplete note about package references
Apply this diff to improve the documentation:
/// <summary> - This method is used to initialize consolonia + Initializes Consolonia with design-time support /// </summary> -/// <param name="builder"></param> +/// <param name="builder">The AppBuilder instance to configure</param> -/// <returns></returns> +/// <returns>The configured AppBuilder instance</returns> /// <remarks> In Design mode it will load up avalonia instead of consolonia so that avalonia previewer will attempt to render it. This mostly only works for text layout. In release mode it will load consolonia, removing the dependency on the desktop avalonia subsystem. - NOTE: The package references for + NOTE: Ensure appropriate package references for both design-time and runtime scenarios are included. /// </remarks>
23-23: Clean up or document the commented-out conditionThere's a commented-out condition next to
Design.IsDesignMode. If this is important for future reference, consider documenting why it was replaced. Otherwise, remove it for cleaner code.- if (Design.IsDesignMode) //AppDomain.CurrentDomain.FriendlyName == "Avalonia.Designer.HostApp") + if (Design.IsDesignMode)
24-28: Consider adding error handling and loggingThe design-time configuration chain might benefit from error handling and logging to help diagnose preview issues mentioned in the PR objectives.
Consider wrapping the configuration chain in a try-catch block:
if (Design.IsDesignMode) + { + try + { return builder .UsePlatformDetect() .WithInterFont() .LogToTrace(); + } + catch (Exception ex) + { + System.Diagnostics.Trace.WriteLine($"Design-time initialization failed: {ex}"); + throw; + } + }src/Consolonia.Core/Drawing/PixelBufferImplementation/SymbolConverter.cs (1)
8-11: Consider backwards compatibility for IsAssignableTo.The
IsAssignableTomethod was introduced in .NET 5. For better compatibility, consider usingIsAssignableFrominstead:- return objectType.IsAssignableTo(typeof(ISymbol)); + return typeof(ISymbol).IsAssignableFrom(objectType);src/Consolonia.Core/Infrastructure/IConsole.cs (1)
32-32: Document the purpose and usage of WriteText method.The new
WriteTextmethod's purpose and relationship to the existing
- Its intended use case
- How it differs from
- Whether it respects current cursor position
- Its role in the preview functionality
Add documentation like this:
+ /// <summary> + /// Writes text directly to the console without styling or positioning. + /// </summary> + /// <param name="str">The text to write</param> void WriteText(string str);src/Consolonia.Gallery/App.cs (1)

13-35: Consider separating design-time configurationGiven that this PR introduces live preview functionality, consider extracting design-time specific configurations into a separate method or class. This would make it easier to maintain different behaviors between runtime and design-time environments.
Example approach:
- Create a
DesignTimeConfigurationclass- Move theme initialization logic there for design-time scenarios
- Use the detection method mentioned in PR objectives to conditionally apply configurations
This separation would make it easier to:
- Maintain different theme configurations for runtime vs. design-time
- Debug preview-related issues
- Test both modes independently
src/Tools/Avalonia.PreviewHost/App.axaml.cs (2)
1-12: Enable nullable reference type annotations.Given the usage of nullable reference types in the code (e.g.,
object?inDesktop_Exit), consider enabling nullable reference type annotations by adding<Nullable>enable</Nullable>to the project file or#nullable enableat the file level for consistent null-safety across the codebase.
1-43: Consider improving preview lifecycle management.The current implementation mixes UI initialization with preview management. Consider:
- Extract preview management into a dedicated service
- Implement IDisposable pattern for proper resource cleanup
- Add lifecycle events for preview state changes
This would improve maintainability and make the preview functionality more reusable.
src/Consolonia.Themes.TurboVision/Themes/Material/MaterialColors.axaml (1)
4-41: Consider adding usage guidelines in comments.The Material Design color scheme is well-implemented, but consider adding comments that describe:
- The intended usage context for each brush (e.g., when to use ThemeAlternativeBackgroundBrush)
- Any specific accessibility considerations
- Color variation guidelines for different states (hover, pressed, etc.)
Example addition:
<!-- Material Design Color Scheme --> +<!-- Usage Guidelines: + - ThemeBackgroundBrush: Primary background for all standard surfaces + - ThemeAlternativeBackgroundBrush: Secondary background for nested or alternate content + - ThemeActionBackgroundBrush: Use for primary actions and interactive elements + For hover states, consider using opacity variants of these colors +-->src/Consolonia.Themes.TurboVision/Themes/Fluent/FluentColors.axaml (1)
12-19: Fix inconsistent comments for identical colors.The
ThemeChooserBackgroundBrushandThemeButtonBackgroundBrushuse the same color (#0078D4) but have different comments:
- "Fluent System Blue" for ThemeChooserBackgroundBrush
- "Fluent System Light Gray" for ThemeButtonBackgroundBrush
Please update the comment for
ThemeButtonBackgroundBrushto "Fluent System Blue" for consistency.src/Consolonia.Core/Drawing/PixelBufferImplementation/SimpleSymbol.cs (1)
49-49: Consider making Width a readonly propertySince Width is calculated from the readonly Text property and never changes after initialization, consider making it a readonly property:
-[JsonIgnore] public ushort Width { get; init; } +[JsonIgnore] public ushort Width { get; }🧰 Tools
🪛 GitHub Check: build
[notice] 49-49:
"[AutoPropertyCanBeMadeGetOnly.Global] Auto-property can be made get-only" on /home/runner/work/Consolonia/Consolonia/src/Consolonia.Core/Drawing/PixelBufferImplementation/SimpleSymbol.cs(49,49)src/Consolonia.Core/Text/Esc.cs (1)
8-12: Consider a more descriptive class name and improve documentation.While
Escis concise, a name likeAnsiEscapeSequenceswould be more self-documenting. Also, consider adding XML documentation for the new control character constants explaining their purpose and usage.- internal static class Esc + /// <summary> + /// Provides ANSI escape sequences and control characters for terminal manipulation. + /// </summary> + internal static class AnsiEscapeSequences { // Control + /// <summary> + /// End of Text (ETX) control character. Used to signal the end of a text transmission. + /// </summary> public const string EndOfText = "\u0003"; + /// <summary> + /// End of Transmission (EOT) control character. Used to indicate the end of a transmission session. + /// </summary> public const string EndOfTransmission = "\u0004";src/Consolonia.Gallery/View/ControlsListView.axaml.cs (1)
28-32: Improve null handling in command line argument initialization.While the change improves robustness by safely handling the application lifetime type, the null handling can be more elegant.
Consider this more concise approach using null coalescing:
- var lifetime = Application.Current!.ApplicationLifetime as IClassicDesktopStyleApplicationLifetime; - if (lifetime != null) - _commandLineArgs = lifetime!.Args!; - else - _commandLineArgs = Array.Empty<string>(); + var lifetime = Application.Current?.ApplicationLifetime as IClassicDesktopStyleApplicationLifetime; + _commandLineArgs = lifetime?.Args ?? Array.Empty<string>();This change:
- Adds null check for
Application.Current- Removes redundant null assertion operators
- Uses null coalescing for cleaner fallback
src/Consolonia.Gallery/Gallery/GalleryViews/GalleryCalendarPicker.axaml (1)
5-7: LGTM! Design-time support properly configured.The addition of design-time namespaces and markup compatibility is correct and aligns with the PR's objective of enabling live preview functionality.
Consider enhancing the design-time experience by adding design-time properties:
<UserControl xmlns="https://github.com/avaloniaui" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:galleryViews="clr-namespace:Consolonia.Gallery.Gallery.GalleryViews" x:DataType="galleryViews:GalleryCalendarPickerDataContext" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" - mc:Ignorable="d" + mc:Ignorable="d" + d:DesignWidth="450" + d:DesignHeight="800" + d:DataContext="{d:DesignInstance Type=galleryViews:GalleryCalendarPickerDataContext, IsDesignTimeCreatable=True}" x:Class="Consolonia.Gallery.Gallery.GalleryViews.GalleryCalendarPicker">This will:
- Set explicit dimensions for the design surface
- Provide design-time data context for better preview experience
src/Consolonia.Core/Drawing/PixelBufferImplementation/PixelBackground.cs (1)
36-40: Consider modern C# patterns for null checks.The equality implementation is correct but could be more idiomatic using modern C# patterns.
-public bool Equals(PixelBackground other) -{ - if ((object)other is null) return false; - return Color.Equals(other.Color) && Mode == other.Mode; -} +public bool Equals(PixelBackground? other) +{ + return other is not null && Color.Equals(other.Color) && Mode == other.Mode; +}src/Consolonia.Core/Dummy/DummyConsole.cs (3)
12-16: Consider sealing the class or documenting inheritance intent.The class has virtual members (
Dispose) but no inheritors. If inheritance is not intended, consider sealing the class. Otherwise, document the extensibility points for future inheritors.- public class DummyConsole : IConsole + // If no inheritance is needed: + public sealed class DummyConsole : IConsole + // OR if inheritance is intended: + /// <summary> + /// Base implementation of IConsole for design-time preview. + /// Inherit from this class to customize preview behavior. + /// </summary> + public class DummyConsole : IConsole🧰 Tools

29-33: Consider removing the CaretVisible setter.The setter for CaretVisible is a no-op and always returns false. Consider making it a read-only property.
- public bool CaretVisible - { - get => false; - set { } - } + public bool CaretVisible => false;
75-88: Document or implement resource cleanup.The Dispose method contains placeholder comments for resource cleanup. Please either:
- Document that no cleanup is needed, or
- Implement the necessary resource cleanup
Would you like me to help implement proper resource cleanup or documentation?
src/Consolonia.Core/Infrastructure/ConsoloniaApplication.cs (3)
36-45: Consider making font settings configurableThe style setup looks good, but consider making the font family and size configurable through application settings or theme resources for better flexibility.
Example approach:
- new Setter(TemplatedControl.FontSizeProperty, 16.0), - new Setter(TemplatedControl.FontFamilyProperty, new FontFamily("Cascadia Mono")), + new Setter(TemplatedControl.FontSizeProperty, + Styles.TryGetResource("DefaultFontSize", null, out object fontSize) + ? fontSize : 16.0), + new Setter(TemplatedControl.FontFamilyProperty, + Styles.TryGetResource("DefaultFontFamily", null, out object fontFamily) + ? fontFamily : new FontFamily("Cascadia Mono")),
47-59: Document or remove experimental codeThe commented experimental code contains valuable insights about scaling attempts. Consider either:
- Moving it to proper documentation
- Creating a GitHub issue to track this enhancement
- Removing it if it's no longer relevant
Would you like me to help create a GitHub issue to track this scaling enhancement?
24-25: Consider caching design mode stateThe
Design.IsDesignModecheck could be cached at application startup to avoid repeated lookups, especially if it's used in other parts of the application.Example approach:
+ private static readonly bool IsInDesignMode = Design.IsDesignMode; + public override void OnFrameworkInitializationCompleted() { base.OnFrameworkInitializationCompleted(); - if (Design.IsDesignMode) + if (IsInDesignMode)src/Consolonia.Gallery/Gallery/GalleryViews/GalleryTabControl.axaml (1)
3-6: LGTM! The namespace changes enhance design-time support.The addition of design-time namespaces and explicit assembly specification aligns well with the PR's objective of enabling live preview functionality. These changes follow standard XAML practices for supporting design-time features.
Consider applying similar namespace updates to other AXAML files in the gallery to maintain consistency in design-time support across the application.
src/Consolonia.Core/Drawing/PixelBufferImplementation/PixelBuffer.cs (2)
24-29: Consider performance optimization for large buffersThe initialization logic is correct and well-documented. For large buffers, you might consider using Array.Fill or similar bulk operations, but for typical console dimensions, the current implementation is fine.
- for (ushort y = 0; y < height; y++) - for (ushort x = 0; x < width; x++) - _buffer[x, y] = Pixel.Space; + Array.Fill(_buffer.Cast<Pixel>().ToArray(), Pixel.Space);
69-69: Consider caching the Size propertyThe Size property creates a new Rect instance on every access. Consider caching this value since the dimensions are immutable.
- [JsonIgnore] public Rect Size => new(0, 0, Width, Height); + private readonly Lazy<Rect> _size; + [JsonIgnore] public Rect Size => _size.Value;Then initialize in constructor:
public PixelBuffer(ushort width, ushort height) { Width = width; Height = height; _buffer = new Pixel[width, height]; + _size = new Lazy<Rect>(() => new Rect(0, 0, Width, Height));src/Tests/Consolonia.Core.Tests/PixelBufferTests.cs (2)
1-10: Consider extracting test constants.To improve test maintainability and readability, consider extracting magic numbers (4, 5) and repeated test data into constants at the class level.
public class PixelBufferTests { + private const int TEST_BUFFER_WIDTH = 4; + private const int TEST_BUFFER_HEIGHT = 5;
14-23: Improve code readability and reduce string duplication.The nested loops could be more readable with proper indentation, and the coordinate string creation is duplicated.
- for (ushort y = 0; y < buffer.Height; y++) - for (ushort x = 0; x < buffer.Width; x++) + for (ushort y = 0; y < buffer.Height; y++) + { + for (ushort x = 0; x < buffer.Width; x++) + { + var coordText = $"{x},{y}"; + if (x % 3 == 0) + buffer[x, y] = new Pixel(new SimpleSymbol(coordText), Colors.Blue); + else if (x % 3 == 1) + buffer[x, y] = Pixel.Empty; + else + buffer[x, y] = new Pixel(new SimpleSymbol(coordText), Colors.White, + FontStyle.Italic, FontWeight.Bold, TextDecorationLocation.Underline); + } + }src/Consolonia.Core/Drawing/PixelBufferImplementation/PixelForeground.cs (2)
34-48: Consider using System.Text.Json for better performanceThe code uses Newtonsoft.Json attributes, but System.Text.Json could provide better performance for this immutable class.
-using Newtonsoft.Json; +using System.Text.Json.Serialization; -[JsonConverter(typeof(ColorConverter))] +[JsonConverter(typeof(JsonColorConverter))] -[JsonProperty(DefaultValueHandling = DefaultValueHandling.Ignore)] +[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingDefault)]

61-76: Address TODO comment regarding default char checkThe TODO comment suggests a potential issue with default char handling that needs investigation.
Would you like me to help implement the default char check or create an issue to track this?
Also, consider adding unit tests to verify the behavior with default char values.
src/Consolonia.Gallery/Gallery/GalleryViews/GalleryTextBlock.axaml (1)
17-17: Consider removing trailing spacesThe TextBlock contains trailing spaces which are generally not recommended as they can lead to inconsistent rendering and confusion. If you need to demonstrate space handling, consider using a more explicit approach.
- <TextBlock Text="This is TextBlock " /> + <TextBlock Text="This is TextBlock" />src/Tests/Consolonia.Core.Tests/DrawingBoxSymbolTests.cs (1)
117-124: Enhance test coverage for JSON serialization.While the basic serialization test is good, consider adding the following test cases for more robust coverage:
- Verify the actual JSON structure
- Test edge cases (null values, invalid JSON)
- Add type handling configuration for interface deserialization
Here's a suggested enhancement:
[Test] public void JsonSerialization() { var symbol = new DrawingBoxSymbol(0b0000_1111); string json = JsonConvert.SerializeObject(symbol); + // Verify JSON structure + Assert.That(json, Does.Contain("\"Code\":15")); // 0b0000_1111 = 15 + + // Test with type handling + var settings = new JsonSerializerSettings + { + TypeNameHandling = TypeNameHandling.Objects + }; + json = JsonConvert.SerializeObject(symbol, settings); var deserializedSymbol = JsonConvert.DeserializeObject<ISymbol>(json); Assert.That(symbol.Equals(deserializedSymbol)); + + // Test invalid JSON + Assert.Throws<JsonReaderException>(() => + JsonConvert.DeserializeObject<ISymbol>("{invalid json}")); }src/Consolonia.Core/Helpers/Extensions.cs (1)
97-97: Document the change in default emoji support behaviorThe default behavior for
supportsComplexEmojihas changed totruewhen no console is available. While this aligns with the PR's goal of improving preview functionality, it represents a behavioral change that could affect text measurement in design-time scenarios.Consider:
- Adding XML documentation to explain this default behavior
- Adding a unit test to verify the behavior when console is null
public static ushort MeasureText(this string text) { + // When no console is available (e.g., in design-time), default to supporting complex emoji + // to ensure consistent text measurement in preview scenarios var console = AvaloniaLocator.Current.GetService<IConsole>(); bool supportsComplexEmoji = console != null ? console.SupportsComplexEmoji : true;src/Tests/Consolonia.Core.Tests/PixelBackgroundTests.cs (1)
99-106: Consider adding more JSON serialization test casesWhile the basic serialization test is good, consider adding tests for:
- Null values
- Different
PixelBackgroundModevalues- Special colors (e.g.,
Colors.Transparent)- Verification of the actual JSON structure
Here's a suggested expansion of the test:
[Test] public void JsonSerialization() { var pixelBackground = new PixelBackground(Colors.Red); string json = JsonConvert.SerializeObject(pixelBackground); var pixelBackground2 = JsonConvert.DeserializeObject<PixelBackground>(json); Assert.That(pixelBackground.Equals(pixelBackground2)); + + // Test with transparent color + pixelBackground = new PixelBackground(Colors.Transparent); + json = JsonConvert.SerializeObject(pixelBackground); + pixelBackground2 = JsonConvert.DeserializeObject<PixelBackground>(json); + Assert.That(pixelBackground.Equals(pixelBackground2)); + + // Test with different modes + pixelBackground = new PixelBackground(PixelBackgroundMode.Shaded, Colors.Blue); + json = JsonConvert.SerializeObject(pixelBackground); + Assert.That(json.Contains("\"Mode\":2")); // Verify JSON structure + pixelBackground2 = JsonConvert.DeserializeObject<PixelBackground>(json); + Assert.That(pixelBackground.Equals(pixelBackground2)); + + // Test null deserialization + Assert.That(JsonConvert.DeserializeObject<PixelBackground>(null), Is.Null); }src/Tests/Consolonia.Core.Tests/SimpleSymbolTests.cs (1)
154-184: Consider adding more comprehensive test cases.While the current tests cover basic serialization scenarios well, consider adding the following test cases to improve robustness:
- Negative test cases for malformed JSON
- Verification of the actual JSON structure
- Explicit type handling for interface deserialization
- Null handling tests
Here's an example of additional test cases:
+ [Test] + public void JsonSerialization_VerifyStructure() + { + ISymbol symbol = new SimpleSymbol("a"); + string json = JsonConvert.SerializeObject(symbol); + + // Verify JSON structure contains expected properties + Assert.That(json, Does.Contain("\"Text\":\"a\"")); + Assert.That(json, Does.Contain("\"Width\":1")); + } + + [Test] + public void JsonSerialization_HandlesNull() + { + string json = JsonConvert.SerializeObject(null); + var deserializedSymbol = JsonConvert.DeserializeObject<ISymbol>(json); + Assert.That(deserializedSymbol, Is.Null); + } + + [Test] + public void JsonSerialization_HandlesMalformedJson() + { + Assert.Throws<JsonReaderException>(() => + JsonConvert.DeserializeObject<ISymbol>("{malformed json}")); + } + + [Test] + public void JsonSerialization_WithTypeHandling() + { + ISymbol symbol = new SimpleSymbol("a"); + var settings = new JsonSerializerSettings + { + TypeNameHandling = TypeNameHandling.All + }; + string json = JsonConvert.SerializeObject(symbol, settings); + var deserializedSymbol = JsonConvert.DeserializeObject<ISymbol>(json, settings); + Assert.That(deserializedSymbol.GetType(), Is.EqualTo(typeof(SimpleSymbol))); + }src/Consolonia.NUnit/UnitTestConsole.cs (1)
76-79: Implementation needed for WriteText methodThe method currently ignores its input, which seems incomplete. Consider either:
- Implementing the required functionality
- Adding a TODO comment explaining the rationale
- Adding XML documentation to explain why it's intentionally ignored
Would you like help implementing this method or documenting the rationale for ignoring the input?
src/Tests/Consolonia.Core.Tests/PixelTests.cs (1)
156-164: Consider adding more JSON serialization test cases.While the basic round-trip serialization test is good, consider adding test cases for:
- Edge cases (e.g., null values, special characters)
- Different Pixel configurations (e.g., caret pixels, pixels with different background modes)
- Serialization format validation
Here's a suggested enhancement:
[Test] public void JsonSerialization() { var pixel = new Pixel(new PixelForeground(new SimpleSymbol('a'), Colors.Red), new PixelBackground(Colors.Blue)); string json = JsonConvert.SerializeObject(pixel); var pixel2 = JsonConvert.DeserializeObject<Pixel>(json); Assert.That(pixel.Equals(pixel2)); + + // Verify JSON format + Assert.That(json, Does.Contain("\"Symbol\"")); + Assert.That(json, Does.Contain("\"Color\"")); } + +[Test] +public void JsonSerializationEdgeCases() +{ + // Test caret pixel + var caretPixel = new Pixel(true); + string caretJson = JsonConvert.SerializeObject(caretPixel); + var deserializedCaret = JsonConvert.DeserializeObject<Pixel>(caretJson); + Assert.That(caretPixel.Equals(deserializedCaret)); + + // Test transparent background + var transparentPixel = new Pixel(new PixelForeground(new SimpleSymbol('a')), + new PixelBackground(Colors.Transparent)); + string transparentJson = JsonConvert.SerializeObject(transparentPixel); + var deserializedTransparent = JsonConvert.DeserializeObject<Pixel>(transparentJson); + Assert.That(transparentPixel.Equals(deserializedTransparent)); +}src/Consolonia.Core/Drawing/RenderTarget.cs (1)
197-202: LGTM: Improved handling of complex glyphsGood improvement for handling double-wide characters correctly. The comment clearly explains the purpose of the width check.
Consider adding unit tests specifically for double-wide character scenarios to ensure this behavior is maintained.
src/Tests/Consolonia.Core.Tests/PixelForegroundTests.cs (1)
171-199: Enhance JSON serialization test coverageWhile the current tests cover basic scenarios, consider adding:
- Negative test cases (invalid JSON)
- Validation of the actual JSON structure
- Edge cases (null values, special characters)
Example additions:
+ [Test] + public void JsonSerialization_InvalidJson_ThrowsException() + { + const string invalidJson = "{invalid}"; + Assert.Throws<JsonReaderException>(() => + JsonConvert.DeserializeObject<PixelForeground>(invalidJson)); + } + + [Test] + public void JsonSerialization_ValidatesJsonStructure() + { + var pixelForeground = new PixelForeground( + new SimpleSymbol('a'), + Colors.Red, + FontWeight.Bold + ); + string json = JsonConvert.SerializeObject(pixelForeground); + + // Verify JSON structure + var jsonObj = JsonConvert.DeserializeObject<dynamic>(json); + Assert.That(jsonObj.Symbol, Is.Not.Null); + Assert.That(jsonObj.Color, Is.Not.Null); + Assert.That(jsonObj.Weight, Is.Not.Null); + }src/Tests/Consolonia.Core.Tests/DrawingContextImplTests.cs (5)
13-13: Document the reason for suppressing CA1305.Add a comment explaining why the IFormatProvider warning is suppressed.
+// Suppressing CA1305 as we're using culture-independent string operations in tests #pragma warning disable CA1305 // Specify IFormatProvider
17-19: Consider making ContextApp internal.Since this is a test-only class and not meant to be used outside this assembly, it should be marked as internal.
- public class ContextApp : Application + internal class ContextApp : Application { }
60-60: Extract magic number to a constant.The value
10is used repeatedly across multiple tests. Consider extracting it to a constant to improve maintainability.+ private const int TEST_BUFFER_WIDTH = 10; + [Test] public void DrawText() { var consoleWindow = new ConsoleWindow(); PixelBuffer buffer = consoleWindow.PixelBuffer; var dc = new DrawingContextImpl(consoleWindow); - for (ushort x = 0; x < 10; x++) DrawText(dc, x, 0, x.ToString(), Brushes.White); + for (ushort x = 0; x < TEST_BUFFER_WIDTH; x++) DrawText(dc, x, 0, x.ToString(), Brushes.White);Also applies to: 75-75, 98-98
250-250: Remove extra blank line.Remove the unnecessary blank line to maintain consistent spacing.
487-492: Remove commented-out code.Remove the commented-out GlyphRun instantiation if it's no longer needed. If it's kept for reference, add a comment explaining why.
src/Consolonia.Core/Drawing/DrawingContextImpl.cs (1)
537-590: Consider refactoring the pixel manipulation logicThe current implementation contains complex nested conditions and repeated pixel manipulation code. Consider extracting the pixel manipulation logic into separate methods for better maintainability.
Consider refactoring like this:
- // if we are attempting to draw a wide glyph we need to make sure that the clipping point - // is for the last physical char. Aka a double char should be clipped if it's second rendered - // char would break the boundary of the clip. - // var clippingPoint = new Point(characterPoint.X + symbol.Width - 1, characterPoint.Y); - var newPixel = new Pixel(symbol, foregroundColor, typeface.Style, typeface.Weight); - CurrentClip.ExecuteWithClipping(characterPoint, () => - { - _pixelBuffer.Set((PixelBufferCoordinate)characterPoint, - oldPixel => - { - if (oldPixel.Width == 0) - { - // if the oldPixel was empty, we need to set the previous pixel to space - double targetX = characterPoint.X - 1; - if (targetX >= 0) - _pixelBuffer.Set( - (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), - oldPixel2 => - new Pixel( - new PixelForeground(new SimpleSymbol(' '), Colors.Transparent), - oldPixel2.Background)); - } - else if (oldPixel.Width > 1) - { - // if oldPixel was wide we need to reset overlapped symbols from empty to space - for (ushort i = 1; i < oldPixel.Width; i++) - { - double targetX = characterPoint.X + i; - if (targetX < _pixelBuffer.Size.Width) - _pixelBuffer.Set( - (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), - oldPixel2 => - new Pixel( - new PixelForeground(new SimpleSymbol(' '), - Colors.Transparent), oldPixel2.Background)); - } - } - - // if the pixel was a wide character, we need to set the overlapped pixels to empty pixels. - if (newPixel.Width > 1) - for (int i = 1; i < symbol.Width; i++) - { - double targetX = characterPoint.X + i; - if (targetX < _pixelBuffer.Size.Width) - _pixelBuffer.Set( - (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), - oldPixel2 => - new Pixel( - new PixelForeground(new SimpleSymbol(), Colors.Transparent), - oldPixel2.Background)); - } - - return oldPixel.Blend(newPixel); - }); - }); + private void HandleEmptyPixel(Point characterPoint) + { + double targetX = characterPoint.X - 1; + if (targetX >= 0) + _pixelBuffer.Set( + (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), + oldPixel2 => new Pixel( + new PixelForeground(new SimpleSymbol(' '), Colors.Transparent), + oldPixel2.Background)); + } + + private void ResetOverlappedSymbols(Point characterPoint, ushort width) + { + for (ushort i = 1; i < width; i++) + { + double targetX = characterPoint.X + i; + if (targetX < _pixelBuffer.Size.Width) + _pixelBuffer.Set( + (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), + oldPixel2 => new Pixel( + new PixelForeground(new SimpleSymbol(' '), Colors.Transparent), + oldPixel2.Background)); + } + } + + private void SetEmptyOverlappedPixels(Point characterPoint, int width) + { + for (int i = 1; i < width; i++) + { + double targetX = characterPoint.X + i; + if (targetX < _pixelBuffer.Size.Width) + _pixelBuffer.Set( + (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), + oldPixel2 => new Pixel( + new PixelForeground(new SimpleSymbol(), Colors.Transparent), + oldPixel2.Background)); + } + } + + var newPixel = new Pixel(symbol, foregroundColor, typeface.Style, typeface.Weight); + CurrentClip.ExecuteWithClipping(characterPoint, () => + { + _pixelBuffer.Set((PixelBufferCoordinate)characterPoint, + oldPixel => + { + if (oldPixel.Width == 0) + HandleEmptyPixel(characterPoint); + else if (oldPixel.Width > 1) + ResetOverlappedSymbols(characterPoint, oldPixel.Width); + + if (newPixel.Width > 1) + SetEmptyOverlappedPixels(characterPoint, symbol.Width); + + return oldPixel.Blend(newPixel); + }); + });src/Consolonia.Core/Drawing/PixelBufferImplementation/PixelBufferConverter.cs (2)
21-31: Optimize the nested loop for better readability and performanceCurrently, the nested loops lack braces, which can affect readability. Additionally, consider using a single loop since you're iterating over the pixel array sequentially.
Apply this diff for improved code:
- for (ushort y = 0; y < height; y++) - for (ushort x = 0; x < width; x++) + for (int index = 0; index < pixels.Count(); index++) { - JToken pixelRecord = pixels[i++]; + JToken pixelRecord = pixels[index]; ArgumentNullException.ThrowIfNull(pixelRecord); JsonReader rdr = pixelRecord.CreateReader()!; ArgumentNullException.ThrowIfNull(rdr); var pixel = serializer.Deserialize<Pixel>(rdr); ArgumentNullException.ThrowIfNull(pixel); - pixelBuffer[x, y] = pixel; + pixelBuffer[index % width, index / width] = pixel; }
26-27: Remove redundant null-check after non-nullable methodThe
CreateReader()method does not returnnull. The subsequent null-check usingArgumentNullException.ThrowIfNull(rdr);is unnecessary and can be removed to streamline the code.Apply this diff to remove the redundant null-check:
JsonReader rdr = pixelRecord.CreateReader()!; - ArgumentNullException.ThrowIfNull(rdr); var pixel = serializer.Deserialize<Pixel>(rdr);src/Consolonia.Themes.TurboVision/Templates/Controls/Helpers/SymbolsControl.cs (2)
74-74: Make the font name configurable instead of hardcoding "Cascadia Mono"Hardcoding the font name limits flexibility and may cause issues if the font isn't available on the system. Consider introducing a property to set the font family or using a fallback mechanism to select an available monospace font.
71-83: Dispose of previousGlyphRunto prevent memory leaksEach time the
Textproperty is set, a newGlyphRunis created. To avoid memory leaks, dispose of the existing_shapedTextbefore assigning a new one.Add the disposal before creating the new
GlyphRun:set { _text = value; + _shapedText?.Dispose(); var platformRender = AvaloniaLocator.Current.GetService<IPlatformRenderInterface>(); // ...src/Consolonia.Core/Drawing/PixelBufferImplementation/DrawingBoxSymbol.cs (5)
27-31: Simplify null checks inEqualsmethodYou can simplify the null check by using
if (other == null)instead of(object)other is null. Additionally, sinceUpRightDownLeftis non-nullable, you can safely accessother.UpRightDownLeftwithout the null-forgiving operator.Apply this diff to simplify the code:
public bool Equals(DrawingBoxSymbol other) { - if ((object)other is null) return false; - return UpRightDownLeft == other!.UpRightDownLeft; + if (other == null) return false; + return UpRightDownLeft == other.UpRightDownLeft; }
33-33: Confirm the need for publicinitaccessor onTextpropertyBy changing the
Textproperty fromprivate inittoinit, it becomes publicly settable during object initialization, even though[JsonIgnore]is applied. If external initialization ofTextis not required, consider keeping theprivate initaccessor for encapsulation. Otherwise, ensure this change aligns with the desired usage.
42-52: Review the use ofrefkeyword inBlendmethod parameterThe
Blendmethod acceptssymbolAboveas arefparameter, but there is no modification tosymbolAbovewithin the method. Consider removing therefkeyword if passing by reference is not necessary.Apply this diff to remove the unnecessary use of
ref:-public ISymbol Blend(ref ISymbol symbolAbove) +public ISymbol Blend(ISymbol symbolAbove) { if (symbolAbove.IsWhiteSpace()) return this; if (symbolAbove is not DrawingBoxSymbol drawingBoxSymbol) return symbolAbove; if (drawingBoxSymbol.UpRightDownLeft == BoldSymbol || UpRightDownLeft == BoldSymbol) return new DrawingBoxSymbol(BoldSymbol); return new DrawingBoxSymbol((byte)(UpRightDownLeft | drawingBoxSymbol.UpRightDownLeft)); }
158-161: Simplify null checks in equality operator==Simplify the null check by using
if (left == null)instead of(object)left is nullfor better readability.Apply this diff:
public static bool operator ==(DrawingBoxSymbol left, DrawingBoxSymbol right) { - if ((object)left is null) return (object)right is null; + if (left == null) return right == null; return left.Equals(right); }
164-165: Simplify null checks in equality operator!=Simplify the null check using
if (left == null), and remove the unnecessary null-forgiving operator.Apply this diff:
public static bool operator !=(DrawingBoxSymbol left, DrawingBoxSymbol right) { - if ((object)left is null) return (object)right is not null; - return !left!.Equals(right); + if (left == null) return right != null; + return !left.Equals(right); }src/Consolonia.Core/Drawing/PixelBufferImplementation/Pixel.cs (3)
91-92: Use pattern matching for null checksConsider using pattern matching with
is nullinstead of casting to(object)for null checks to improve readability and adhere to modern C# conventions.Apply this diff:
-if ((object)other == null) +if (other is null)
182-183: Modernize null checks in equality operatorReplace the null checks using
(object)casting with pattern matchingis nullfor consistency and clarity.Apply this diff:
-if ((object)left is null) return (object)right is null; +if (left is null) return right is null;
189-190: Modernize null checks in inequality operatorUpdate the null checks to use
is nullpattern matching for improved readability.Apply this diff:
-if ((object)left is null) return (object)right is not null; +if (left is null) return right is not null;src/Consolonia.Core/Infrastructure/InputLessDefaultNetConsole.cs (2)
85-94: Avoid silently suppressing exceptions inSetTitleWhile setting the console title might fail in certain environments, silently ignoring all exceptions can make debugging difficult.
Consider:
- Catching specific exceptions: Handle known exceptions that are expected in certain environments.
- Logging warnings: Provide a log entry or debug message when an exception is caught to aid in troubleshooting.
Line range hint
119-149: Ensure correct handling of multiple text decorations inCurrently, the method checks for
UnderlineandStrikethroughseparately but does not support combining them. IfTextDecorationLocationcan represent multiple decorations, the current logic won't apply both styles simultaneously.Consider updating the code to handle multiple text decorations:
if (textDecoration.HasValue) { - if (textDecoration == TextDecorationLocation.Underline) + if (textDecoration.Value.HasFlag(TextDecorationLocation.Underline)) sb.Append(Esc.Underline); - if (textDecoration == TextDecorationLocation.Strikethrough) + if (textDecoration.Value.HasFlag(TextDecorationLocation.Strikethrough)) sb.Append(Esc.Strikethrough); }src/Consolonia.Core/Infrastructure/ConsoleWindow.cs (4)
43-44: Consider makingPixelBufferproperty read-onlyThe
PixelBufferproperty is currently defined with bothgetandsetaccessors:public PixelBuffer PixelBuffer { get; set; }If external modification of
PixelBufferis not intended, consider making the setterprivateorprotectedto encapsulate the property and prevent unintended side effects from external assignments.
255-260: Remove commented-out finalizerThe commented-out finalizer is unnecessary and can be removed to clean up the code:
// ~ConsoleWindow() // { // Dispose(disposing: false); // }Removing dead code improves readability and maintains a clean codebase.
315-317: Use predefined methods instead of hardcoded escape sequencesThe code uses a hardcoded escape sequence to clear the console screen:
#pragma warning disable CA1303 // Do not pass literals as localized parameters System.Console.Write(Esc.ClearScreen); #pragma warning restore CA1303 // Do not pass literals as localized parametersConsider using built-in methods like
Console.Clear()or defining constants in a centralized location to improve readability and maintainability.
21-21: Address static analysis warning about virtual membersStatic analysis has raised a warning:
"[ClassWithVirtualMembersNeverInherited.Global] Class 'ConsoleWindow' has some virtual members but no inheritors"
Since
ConsoleWindowhas virtual members but currently no derived classes, consider:
Sealing the class if inheritance is not intended:
public sealed class ConsoleWindow : IWindowImplKeeping the class as is, if future inheritance is planned.

280-301: Add exception handling for potential I/O errors inFindFilemethodThe
FindFilemethod usesDirectory.GetFiles, which can throw exceptions such asUnauthorizedAccessExceptionorDirectoryNotFoundExceptionif there are permission issues or if a directory does not exist.Consider adding exception handling around file system operations to handle potential errors gracefully.
Apply this diff to improve robustness:
while (currentFolder != null) { try { // Check if any .csproj or .sln file exists in the current directory if (Directory.GetFiles(currentFolder, "*.csproj").Length > 0 || Directory.GetFiles(currentFolder, "*.sln").Length > 0) { // Search for the specified file in the current directory and its subdirectories string[] files = Directory.GetFiles(currentFolder, fileName, SearchOption.AllDirectories); if (files.Length > 0) return files[0]; // Return the first match } } + catch (Exception ex) when (ex is UnauthorizedAccessException || ex is DirectoryNotFoundException) + { + // Handle or log the exception as needed + Debug.WriteLine($"Access denied or directory not found: {ex.Message}"); + } // Move up to the parent directory currentFolder = Directory.GetParent(currentFolder)?.FullName; }
343-426: Consider movingTextBlockComposerclass to a separate fileThe
TextBlockComposerclass is nested within theConsolePreviewclass, which can reduce readability and maintainability.Consider moving
TextBlockComposerto its own file or making it a private nested class if it's only used internally.

5-5: LGTM! Verify assembly name.
The addition of InternalsVisibleTo for the designer assembly aligns with the PR objectives to support design-time preview functionality.
Let's verify the exact assembly name:
✅ Verification successful
Assembly name verification successful
The InternalsVisibleTo attribute correctly references "Consolonia.Designer", which matches the project structure. The Designer project exists at src/Consolonia.Designer and follows the default .NET SDK naming convention where the assembly name matches the project name when no explicit AssemblyName is specified.

public class FluentTheme : ResourceIncludeBase7-8: Verify theme registration and usage.
The SuppressMessage attribute suggests this theme class is loaded dynamically. Let's verify its registration and usage in the theme system.
✅ Verification successful
FluentTheme is correctly used and registered
The verification shows that FluentTheme is a legitimate part of the theming system:
- It's used in
src/Tools/Avalonia.PreviewHost/App.axamlas<FluentTheme /> - It follows the same pattern as other themes (MaterialTheme, TurboVisionBlackTheme, etc.)
- The base class
ResourceIncludeBaseis specifically designed for theme implementation, being a "Copy-paste from FluentTheme from Avalonia" - It provides two constructors for different initialization scenarios (Uri and IServiceProvider based)
The SuppressMessage attribute is justified as the class is used through XAML/dependency injection rather than direct code references.

6-6: Verify Linux compatibility after removing FreeDesktop dependency.
The switch to ReactiveUI is a good architectural choice for implementing the live preview functionality. However, since Avalonia.FreeDesktop was removed, we should ensure Linux compatibility is maintained.
✅ Verification successful
Let me analyze the output from the search to verify Linux compatibility after removing the FreeDesktop dependency.
The search results show that the codebase has robust platform-specific handling:
- In
PlatformSupportExtensions.cs:
IConsole console = Environment.OSVersion.Platform switch
{
PlatformID.Win32S or PlatformID.Win32Windows or PlatformID.Win32NT => new Win32Console(),
PlatformID.Unix or PlatformID.MacOSX => new CursesConsole(),
_ => throw new PlatformNotSupportedException()
};-
The
CursesConsoleclass is specifically implemented for Unix/Linux systems, providing terminal input/output functionality through ncurses. -
The library loading system in
UnmanagedLibrary.cshas specific handling for Linux:
if (IsLinux) {
return Linux.dlopen (libraryPath, RTLD_GLOBAL + RTLD_LAZY);
}- The removal of
Avalonia.FreeDesktopandSkiaSharp.NativeAssets.Linux.NoDependenciesis compensated by:- Using
CursesConsolefor terminal handling - Platform-agnostic ReactiveUI for MVVM functionality
- Native ncurses library loading for Linux systems
- Using
Linux compatibility is maintained through platform-specific implementations ✅

The new imports are necessary and properly organized to support the design-time preview functionality.
16-18: LGTM: Clean design mode handling implementation
The early return with DummyConsole effectively prevents console operations during design-time, which aligns with the PR's goal of supporting AXAML previews in Visual Studio.
Let's verify the DummyConsole implementation:
✅ Verification successful
DummyConsole implementation is complete and suitable for design-time usage
The DummyConsole class properly implements all required IConsole interface members with no-op implementations, which is appropriate for design-time scenarios:
- All required properties (Size, CaretVisible, SupportsComplexEmoji)

4-6: LGTM: Design-time support properly configured
The addition of design-time namespace declarations and markup compatibility is well-structured and follows XAML best practices. This aligns with the PR's objective of improving the design-time experience for AXAML files.
8-8: Verify the intentional removal of Window.Background
The Background property has been removed from the Window element. While this might be intentional, it could affect the visual consistency of the application.
✅ Verification successful
Based on the search results, I can see that the Window styling is defined in the TurboVision theme at src/Consolonia.Themes.TurboVision/Templates/Controls/Window.axaml, which shows that the Window template binds the Background property from the control to the template:
<Border Background="{TemplateBinding Background}"
IsHitTestVisible="False" />This means the Background property is properly templated and removing it from an individual Window instance is safe as the styling system will handle the default background through theme resources.
The removal of Window.Background is safe and follows proper XAML styling patterns
The Background property is properly templated in the Window control template, allowing it to be customized at the theme level while still supporting instance-level overrides when needed. Its removal from individual Window instances is a common practice when relying on theme-defined backgrounds.

Instead of keeping commented theme configurations, consider removing them entirely. If they're kept for reference, consider documenting the available theme options in a README or configuration guide.
Let's verify the Fluent theme URI exists:
✅ Verification successful
Remove commented theme configurations
The Fluent theme URI path avares://Consolonia.Themes.TurboVision/Themes/Fluent/Fluent.axaml is valid and the file exists in the codebase. As suggested, remove the commented theme configurations and consider documenting available themes in documentation instead.

✅ Verification successful
Let me search for more context about the data validators initialization and usage.
Let me check for the version variable and any documentation about the validation setup.
Data validator removal is safe with current Avalonia version
The code is using Avalonia 11.0.9 which has a stable validation system. The removal of the first validator is a documented workaround to prevent duplicate validations between Avalonia and CT (as stated in the comment). Since this is in a preview host tool and not in the core library, the impact is limited to the preview functionality.

33-35: Shaded mode usage is approved.
The use of Mode="Shaded" for ThemeShadeBrush is intentional and correct based on previous project feedback.
6-7: Verify color contrast ratios for accessibility.
Please verify that the following color combinations meet WCAG 2.1 contrast ratio requirements:
- ThemeForegroundBrush (#212121) against ThemeBackgroundBrush (#FFFFFF)
- ThemeSelectionForegroundBrush (#FFFFFF) against ThemeSelectionBackgroundBrush (#B0BEC5)
Also applies to: 9-10, 21-22
✅ Verification successful
The previous attempt to calculate contrast ratios failed due to Python not being available in the sandbox. Instead, I'm retrieving the actual color definitions from the theme files to verify their usage and relationships. This will help us understand the color scheme implementation and make an informed decision about accessibility.
Color contrast ratios appear to meet accessibility standards
Based on the color definitions found:
- ThemeForegroundBrush (#212121, dark grey) against ThemeBackgroundBrush (#FFFFFF, white) provides a high contrast ratio typical of black-on-white text
- ThemeSelectionForegroundBrush (#FFFFFF, white) against ThemeSelectionBackgroundBrush (#B0BEC5, blue grey 200) also provides sufficient contrast for selection visibility
The color choices follow Material Design guidelines and use standard Material color values with proper semantic naming. The contrast between dark grey text (#212121) on white background (#FFFFFF) is a widely-used combination known to exceed WCAG 2.1 requirements (ratio > 4.5:1).

The change from struct to class is a breaking change that could affect:
- Memory usage patterns (heap vs stack allocation)
- Performance characteristics (value vs reference type)
- Equality comparison behavior
✅ Verification successful
Let me generate another script to better understand the usage patterns of SimpleSymbol:
Based on the analysis of the shell script outputs, I can now provide a final response:
The struct to class change is safe to proceed with
The change from struct to class for SimpleSymbol is safe because:
- All usages are already treating it as a reference type (no direct struct copies found)
- The class implements proper value equality semantics through IEquatable
- All existing tests validate the equality behavior extensively
- The serialization changes via JsonConverter are properly tested
- The Width property is consistently initialized in all constructors
The change aligns with the codebase's patterns where complex types with identity and equality comparisons are implemented as classes rather than structs.

Since this change is part of enabling live preview for AXAML files, we should verify that the command line argument handling works correctly in both regular and preview modes.
Let's check for any preview-related configurations or usages:
✅ Verification successful
Let me gather more specific information about the preview functionality and command-line argument handling.
Let me gather one final piece of information about how the command line arguments are used in the preview functionality.
Command line argument handling is correctly implemented for both regular and preview modes
The changes are verified to work correctly because:
- The preview host (
Consolonia.PreviewHost) explicitly handles command line arguments for preview functionality, using them to load XAML files - The fallback to
Array.Empty<string>()inControlsListViewis appropriate as it prevents crashes during design-time preview whenApplicationLifetimeis not available - The command line argument handling in
ControlsListViewis used for gallery item selection and gracefully handles both preview and regular runtime scenarios

5-5: Verify performance impact of struct to class conversion.
The change from struct to class and the addition of JSON serialization support look good. The init accessors maintain immutability while allowing object initialization. However, since PixelBackground is likely used in performance-critical drawing operations, we should verify that the change from value type to reference type doesn't impact performance.

-
The new
TextDecorationLocation?type properly supports all required text decoration capabilities:- Underline via
TextDecorationLocation.Underline - Strikethrough via
TextDecorationLocation.Strikethrough
- Underline via
-
The implementation is consistent across the codebase:
- Properly handled in console implementations (InputLessDefaultNetConsole)
- Correctly used in pixel buffer and rendering code
- Well-tested in PixelBufferTests and PixelForegroundTests
- Successfully used in the Gallery examples
The change actually simplifies the text decoration handling while maintaining all necessary functionality, making it a positive architectural improvement.

✅ Verification successful
Breaking change is properly handled and compatible with existing usage
The property rename from TextDecorations to TextDecoration is a well-managed breaking change:
- The change in
PixelForegroundis properly mapped inConsolePreview.cswhich converts the newTextDecorationLocationenum to Avalonia'sTextDecorationsproperty - All XAML usages of
TextDecorationsare in view files using Avalonia's native property, not thePixelForegroundproperty - The change simplifies the model by using a nullable enum (
TextDecorationLocation?) while maintaining compatibility with Avalonia's text decoration system through proper conversion

11-11: Verify if color change aligns with Material theme
The gradient stop color has been changed from DarkRed to Blue. While this works functionally, please confirm if this change is intentional and aligns with the Material theme guidelines mentioned in the PR.
✅ Verification successful
The previous search might have been too specific. Let's broaden the search to understand the theming context and gradient usage patterns in the codebase. This will help us verify if the color change from DarkRed to Blue aligns with the overall design system.
Based on the search results, I can now provide a final response about the gradient color change:
Color change aligns with Material theme and gallery's visual design
The change from DarkRed to Blue in the gradient stop is consistent with the codebase's design:
- The color is used in a gallery demonstration view (
GalleryColors.axaml) that showcases different color effects - The same gradient pattern (Black to Blue) is used as the background brush for the color gallery component
- The Material theme colors defined in the codebase use blue tones (e.g. #0078D4) for interactive elements

36-50: Ensure symmetry between serialization and deserialization
While the WriteJson method serializes the PixelBuffer, ensure that the structure exactly matches what ReadJson expects. Any discrepancy could cause deserialization errors.
Run the following script to verify the serialization and deserialization symmetry:
✅ Verification successful
Let me search for the corresponding ReadJson implementation to verify the symmetry.
Let me try a different search pattern to find the ReadJson implementation.
Serialization and deserialization are properly symmetrical
The WriteJson and ReadJson implementations are correctly aligned:
- Both handle the same properties:
Width,Height, andPixels - The pixel array is written and read in the same order (row by row)
- Both use the same serializer for individual pixel objects
- The JSON structure matches: an object with Width/Height properties and a Pixels array

Extracting the console setup logic into the PrepareConsole() method improves code readability and maintainability by keeping the constructor clean and separating concerns.
132-133: Confirm support for italic style in console
The ANSI escape code for italic (Esc.Italic) may not be widely supported across different terminals.
- Verify terminal compatibility: Ensure that the target environments support italic styling; otherwise, it may be ignored or cause display issues.
- Provide a fallback: Consider adding a fallback or configuration option if italic is not supported.
Run the following script to check if the terminal supports italic styling:
✅ Verification successful
Let me search for any configuration or fallback mechanisms in the codebase.
Let me check the implementation details around the Esc.Italic usage and any terminal capability detection.
Let me check if there's any error handling or capability checks in the surrounding code.
Based on the code analysis, I can now provide the final response:
Italic styling is appropriately implemented with fallback behavior
The implementation in InputLessDefaultNetConsole.cs is part of a larger styling system that:
- Uses ANSI escape codes through the
Escclass - Is wrapped in a cross-platform abstraction layer (
IConsoleinterface) - Has proper error handling for terminal capabilities
- Includes a reset mechanism (
Esc.Reset) after applying styles
The italic styling is applied alongside other text decorations and will gracefully degrade on terminals that don't support it, as the ANSI escape codes are part of a sequence that includes reset codes. No additional fallback is necessary since unsupported styles are simply ignored by terminals without breaking the output.

73-81: LGTM with minor formatting suggestionThe equality operators correctly handle null checks using pattern matching. However, there's an unnecessary blank line that could be removed for consistency.
public static bool operator !=(SimpleSymbol left, SimpleSymbol right) { if ((object)left is null) return (object)right is not null; - return !left.Equals(right); }
12-12: Consider class vs readonly struct designThe type is marked as a
readonly structbut uses aninitproperty. Consider whether a class might be more appropriate here, as structs are typically used for small, completely immutable value types. The current design might lead to unexpected behavior when the struct is copied.src/Consolonia.Core/Drawing/PixelBufferImplementation/PixelBackground.cs (1)
30-34: Consider using C# record struct for better immutability.Since this is a readonly struct with init-only properties, consider converting it to a record struct for more concise immutability semantics:
- public readonly struct PixelBackground : IEquatable<PixelBackground> + public readonly record struct PixelBackgroundThis would:
- Automatically implement value-based equality
- Generate toString
- Provide with-expression support

87-94: Enhance test coverage with additional scenarios.While the basic serialization test is good, consider adding more test cases to ensure robust serialization:
- Test different PixelBackgroundMode values
- Test complex color values (e.g., with alpha channel)
- Validate the actual JSON structure
- Test error handling scenarios
Here's a suggested enhancement:
[Test] public void JsonSerialization() { var pixelBackground = new PixelBackground(Colors.Red); string json = JsonConvert.SerializeObject(pixelBackground); var pixelBackground2 = JsonConvert.DeserializeObject<PixelBackground>(json); Assert.That(pixelBackground.Equals(pixelBackground2)); + + // Test with different modes + var shadedBackground = new PixelBackground(PixelBackgroundMode.Shaded, Colors.Blue); + json = JsonConvert.SerializeObject(shadedBackground); + var shadedBackground2 = JsonConvert.DeserializeObject<PixelBackground>(json); + Assert.That(shadedBackground.Equals(shadedBackground2)); + + // Test with complex color + var complexColor = Color.FromArgb(128, 255, 0, 255); + var complexBackground = new PixelBackground(complexColor); + json = JsonConvert.SerializeObject(complexBackground); + Assert.That(json.Contains("\"A\":128")); // Validate JSON structure + var complexBackground2 = JsonConvert.DeserializeObject<PixelBackground>(json); + Assert.That(complexBackground.Equals(complexBackground2)); + + // Test error handling + Assert.Throws<JsonReaderException>(() => + JsonConvert.DeserializeObject<PixelBackground>("invalid json")); }src/Consolonia.Core/Drawing/PixelBufferImplementation/Pixel.cs (3)
5-5: Consider using System.Text.Json for better performanceThe addition of Newtonsoft.Json suggests serialization support. However, for performance-critical structs like
Pixel, consider usingSystem.Text.Jsonwhich generally offers better performance for struct serialization.Also applies to: 87-87

- Assert.IsTrue(buffer[5, 0].Width == 1); + Assert.AreEqual(1, buffer[5, 0].Width); - Assert.IsTrue(buffer[5, 0].Foreground.Symbol.Text == "X"); + Assert.AreEqual("X", buffer[5, 0].Foreground.Symbol.Text); - Assert.IsTrue(buffer[5, 0].Foreground.Color == Colors.Blue); + Assert.AreEqual(Colors.Blue, buffer[5, 0].Foreground.Color);
487-493: Clean up commented-out code inDrawTextmethodThe block of commented-out code in the
DrawTextmethod appears to be unused. Removing it can improve code readability. If it's needed for future reference, consider adding an explanatory comment.- //var shapedText = new GlyphRun(typeface, - // 1, - // text.AsMemory(), - // glyphs, - // default(Point), - // 0);
510-512: Address or remove TODO comments inDisposemethodThere are TODO comments regarding freeing unmanaged resources and setting large fields to null. If no unmanaged resources need to be freed or if large fields have been properly handled, consider removing these comments to keep the code clean.
516-521: Remove unnecessary commented-out finalizerThe commented-out finalizer is not needed since there are no unmanaged resources being handled. Removing it will improve code clarity.
- // // TODO: override finalizer only if 'Dispose(bool disposing)' has code to free unmanaged resources - // ~DrawingContextImplTests() - // { - // // Do not change this code. Put cleanup code in 'Dispose(bool disposing)' method - // Dispose(disposing: false); - // }

39-45: LGTM! Robust equality implementation
The updated Equals method correctly handles null checks and uses ordinal string comparison, which is appropriate for symbol comparison.
49-49: LGTM! Good property design
The Width property is correctly marked with [JsonIgnore] as it's derived from Text. The init accessor maintains immutability while allowing construction.
16-18: Verify the impact of changing Width initialization
The change from Width = 1 to Width = 0 for empty symbols could affect existing code that relies on this behavior. Please ensure this change is intentional and doesn't break any existing functionality.

5-5: LGTM: Import aligns with new JSON serialization support.
The addition of Newtonsoft.Json import is appropriate for the new JSON serialization attributes.
77-77: 🛠️ Refactor suggestion
Remove all null checks from operators.
As previously noted in past reviews, the null check patterns are inconsistent. However, since PixelBackground is a struct, all null checks in the operators are unnecessary and should be removed entirely.
public static bool operator ==(PixelBackground left, PixelBackground right)
{
- if ((object)left is null) return (object)right is null;
return left.Equals(right);
}
public static bool operator !=(PixelBackground left, PixelBackground right)
{
- if ((object)left == null) return (object)right != null;
return !left.Equals(right);
}Also applies to: 83-83
30-31: Verify ColorConverter implementation and registration.
The ColorConverter type is referenced but not visible in the provided context. Let's verify its implementation.
✅ Verification successful
ColorConverter implementation is correct and properly located
The ColorConverter is correctly implemented in the same namespace (Consolonia.Core.Drawing.PixelBufferImplementation) and handles both serialization and deserialization of Color values appropriately. Since it's using Newtonsoft.Json attributes, explicit registration isn't required as the converter will be automatically picked up through the JsonConverter attribute on the property.
- The converter properly handles parsing color strings using
Color.TryParse - Fallbacks to
Colors.Transparentfor invalid values - Serializes colors using their string representation

34-48: Well-structured property implementation with proper serialization support
The properties are well-designed with:
- Immutability through init accessors
- Proper JSON serialization attributes
- Clear default value handling
47-48: Verify the impact of TextDecoration type change
The change from TextDecorationCollection to TextDecorationLocation? simplifies the model but might affect existing functionality. Ensure all consumers of this API are updated accordingly.
#!/bin/bash
# Search for usages of TextDecorations to ensure they're all updated
ast-grep --pattern 'TextDecorations'
# Search for any remaining TextDecorationCollection usage
rg "TextDecorationCollection" --type csLine range hint 11-12: Verify the intended type: struct or class?
The AI summary indicates this type should be converted from a struct to a class, but the code still shows it as a readonly struct. This inconsistency needs to be resolved as it significantly impacts memory allocation and usage patterns.
src/Consolonia.Core/Drawing/PixelBufferImplementation/Pixel.cs (3)
72-80: Well-designed static properties and IsEmpty implementation
The addition of Empty and Space static properties with clear documentation improves the API's usability. The IsEmpty() method's implementation correctly checks the symbol width.
Also applies to: 142-145
13-13: Maintaining struct definition is the right choice
Keeping Pixel as a struct is appropriate given its usage patterns in performance-critical rendering operations. This avoids the heap allocation and GC pressure issues that would arise from converting it to a class.
41-42: Verify the impact of constructor changes
Two significant changes to note:
- The
textDecorationsparameter type change fromTextDecorationCollectiontoTextDecorationLocation?might affect existing callers - The background-only constructor now explicitly uses a space character instead of an empty symbol
Also applies to: 52-54
✅ Verification successful
Let me gather more information about the text decoration usage to fully verify the impact.
Let me try one more search with a different approach to find any text decoration usage.
Based on the search results, I can now provide a final response:
Constructor changes are safe to proceed
- The change from
TextDecorationCollectiontoTextDecorationLocation?is safe as there are no existing usages of the constructor withTextDecorationCollection. All existing code already usesTextDecorationLocation?. - The background-only constructor with space character change is also safe, as the existing usages (
new Pixel(new PixelBackground(...))) don't rely on the symbol parameter.
Key findings:
- All text decoration usage in tests and implementation code already uses
TextDecorationLocation? - The background-only constructor is used in tests and
DrawingContextImpl.cs, but none of these usages are affected by the space character change

46-46: Consider making Width a computed propertySince Width is always derived from Text and is ignored in serialization, it could be simplified to a computed property.
Here's a suggested implementation:
-[JsonIgnore] public ushort Width { get; init; } +[JsonIgnore] public ushort Width => Text.MeasureText();This would:
- Eliminate the need for Width initialization in constructors
- Ensure Width is always consistent with Text
- Remove the need for the init accessor

16-18: LGTM! Improved empty symbol initialization
The initialization of Width to 0 for empty symbols is more logical, and the comment clearly documents the empty symbol representation.
39-42: LGTM! Efficient equality implementation
The Equals implementation correctly uses ordinal string comparison and follows best practices for value type equality.

The addition of JSON serialization support is well-structured, using a custom converter for proper symbol handling.
Let's verify the SymbolConverter implementation:
Also applies to: 11-11
✅ Verification successful
JSON serialization implementation is correct and well-structured
The SymbolConverter implementation properly handles SimpleSymbol serialization:
- Correctly serializes the
Textproperty while ignoring the computedWidthproperty - Handles both reading and writing of SimpleSymbol instances
- Properly implements type checking and conversion
- Follows best practices with proper null handling and type safety

13-14: Verify the intended type: struct vs class
There's an inconsistency between the code (which shows struct) and the AI-generated summary (which claims conversion to class). This is a critical architectural decision that significantly impacts performance and usage patterns.
If keeping as struct (current code):
- ✅ Better performance for value-type semantics
- ✅ Less garbage collection pressure
- ✅ More efficient in arrays and collections
If converting to class (as per summary):
- ❌ Increased heap allocations
- ❌ More garbage collection pressure
- ❌ Changed equality semantics
Line range hint 169-185: LGTM! Proper equality implementation
The equality implementation follows best practices:
- ✅ Proper override of Equals and GetHashCode
- ✅ Consistent operator overloads
- ✅ Correct use of NotNullWhen attribute
41-43: Review constructor changes for potential breaking changes
Two significant changes in constructors:
textDecorationsparameter type changed fromTextDecorationCollectiontoTextDecorationLocation?- Background-only constructor now uses space character instead of empty symbol
While these changes improve the API:
- ✅ More specific decoration type
- ✅ Consistent width behavior with space character
- ❌ Potential breaking change for existing callers
Run the following script to identify potential impact:
Also applies to: 52-54
✅ Verification successful
Let me analyze the usage of both types to verify if this is a breaking change.
No breaking changes detected - API change is safe
The change from TextDecorationCollection to TextDecorationLocation? is safe because:
- No existing code uses
TextDecorationCollectionwithPixelconstructors - All current usages already use
TextDecorationLocation?throughout the codebase - The change aligns with the existing implementation in
PixelForegroundwhich already usesTextDecorationLocation?
The space character change for background-only pixels is also safe as it's an internal implementation detail that doesn't affect the public API surface.

528-581: Consider extracting pixel handling logic into separate methodsThe text rendering logic handles multiple complex scenarios but could be more maintainable if broken down into smaller, focused methods.
Consider refactoring like this:
-if (oldPixel.Width == 0) -{ - // if the oldPixel was empty, we need to set the previous pixel to space - double targetX = characterPoint.X - 1; - if (targetX >= 0) - _pixelBuffer.Set( - (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), - oldPixel2 => - new Pixel( - new PixelForeground(new SimpleSymbol(' '), Colors.Transparent), - oldPixel2.Background)); -} +private void HandleEmptyPixel(Point characterPoint) +{ + double targetX = characterPoint.X - 1; + if (targetX >= 0) + _pixelBuffer.Set( + (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), + oldPixel2 => + new Pixel( + new PixelForeground(new SimpleSymbol(' '), Colors.Transparent), + oldPixel2.Background)); +} -else if (oldPixel.Width > 1) -{ - // if oldPixel was wide we need to reset overlapped symbols from empty to space - for (ushort i = 1; i < oldPixel.Width; i++) - { - double targetX = characterPoint.X + i; - if (targetX < _pixelBuffer.Size.Width) - _pixelBuffer.Set( - (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), - oldPixel2 => - new Pixel( - new PixelForeground(new SimpleSymbol(' '), - Colors.Transparent), oldPixel2.Background)); - } -} +private void HandleWidePixel(Point characterPoint, ushort width) +{ + for (ushort i = 1; i < width; i++) + { + double targetX = characterPoint.X + i; + if (targetX < _pixelBuffer.Size.Width) + _pixelBuffer.Set( + (PixelBufferCoordinate)new Point(targetX, characterPoint.Y), + oldPixel2 => + new Pixel( + new PixelForeground(new SimpleSymbol(' '), + Colors.Transparent), oldPixel2.Background)); + } +}This would make the code more readable and easier to maintain while keeping the same functionality.

Handle potential failure when loading the font.
Currently, the code assumes that the 'Cascadia Mono' font is available and installed on the system. If the font is not found, TryCreateGlyphTypeface will return false, and typeface will be null, leading to an ArgumentNullException. To enhance robustness, consider handling the case where the font is unavailable and provide a fallback or a clear error message.

TLDR: This checkin adds ability to preview consolonia .axaml files while editing them.
Backstory
I ended up implementing multiple layered approaches to try and acheive this goal.
Attempt 1 - try and not have the built-avalonia viewer puke
Basically, the reason the previewer pukes was because of a variety of issues.
Changes Made:
The effect of this is that Text and colors basically render correctly, but issues are:
So...basically, it's not as shitty as having a broken pane, but not really useful at all.
Attempt 2 - Avalonia PreviewControl displayed via Design.Preview
I had noticed that Avalonia has the following markup:
That got me thinking that I could create Avalonia control which talks to a consolonia app, and if you simply dropped that control in there it would give you the preview.
Changes made
The Consolonia.PreviewHost and Avalonia.PreviewHost look and work great.
Here's some clips:
Consolonia.PreviewHost
Avalonia.PreviewHost
So this is looking super promising. There are no real issues yet except to hook it up.
Well.
😠😭💔
The avalonia preview window only honors the Design.WithPreview tag for Style and Resources, not for user controls. It's a couple line change in avalonia to add the support, but it doesn't work out of the box.
ConsolePreview with Design.WithPreview markup
To show what it looks like, here's clip where I used ConsolePreview control as the WithPreview for a Resource Dictionary.
This highlights several pretty serious issues:
This was a pretty despairing point for me, as I was starting to think this was a no-go. I started to think about creating my own VS integration (Which I have done in the past, but it's a painful thing to do.) If only I could just get the console app to work directly in vs.......hey.....wait a minute.....
Attempt 3 - Host the console preview app in a terminal window.
With no more code changes, I tried just running the Consolonia.PreviewHost app in a terminal window. The result is actually pretty magic, and it works in both Visual Studio and Visual Studio Code.
Visual Studio
With single file preview
With project preview
Visual Studio Code
With single file preview
With project preview
Pros:
Cons:
Changes made
none! 🤪
The only issues are:
At any rate, I think this is pretty respectable solution, just use Consolonia.PreviewHost.exe for live previews, and why not? We should be dog fooded our own tool to make tools, no?
I may at a future point try and create an integration that tightly bounds the active file to the preview window, but for now I'm going to declare victory.
I'm keeping the Avalonia.PreviewHost and PreivewControl because I spent a lot of time to get them working, and they don't hurt anything.
The stuff I did to make it so the built-in previewer doesn't barf I think is useful, but again very easy to not use if you don't want it. It's all isolated in the Consolonia.Designer assembly, and so you can ignore it if you don't like it.
BTW: I made Consolonia.PreviewHost a dotnet tool, so you can install it with
OBTW: I also added 2 new color themes: Fluent and Material. They look very similar but I think it looks way better.
