Huskui.Avalonia.Code 1.1.0

Huskui.Avalonia.Code

A syntax-highlighted code viewer extension for Huskui.Avalonia, powered by TextMate grammars with a lightweight inline renderer.

Relationship to Huskui.Avalonia

Huskui.Avalonia.Code is an extension library for Huskui.Avalonia — it cannot be used standalone.

• Prerequisite: You must install Huskui.Avalonia and use HuskuiTheme in your application
• Auto-loading: Once the assembly is loaded, HuskuiTheme automatically merges the extension's theme resources via the [HuskuiExtension] mechanism — no manual style includes needed
• Shared namespace: Controls are mapped to https://github.com/d3ara1n/Huskui.Avalonia, using the same husk: XAML prefix as the core library

Installation

dotnet add package Huskui.Avalonia
dotnet add package Huskui.Avalonia.Code

<husk:CodeViewer Code="{Binding SourceCode}" Language="csharp" />

C# Example

var viewer = new CodeViewer
{
    Language = "csharp",
    Code = """
        public class Hello
        {
            public void Greet() => Console.WriteLine("Hello!");
        }
        """
};

Language Support

CodeViewer uses TextMate grammars through TextMateSharp.Grammars. Languages are resolved through built-in aliases and file-extension-style mappings, then fall back to plain text if no grammar is available.

Supported Languages

Note: The full list of supported languages depends on the bundled TextMate grammars. If a language is not recognized, the code is rendered as plain text without syntax highlighting.

Features

• Syntax Highlighting — TextMate-based tokenization with Huskui Radix light/dark token themes
• Line Numbers — Optional lightweight line number gutter
• Copy to Clipboard — Header bar with language label and copy button
• Lightweight Rendering — Code content is rendered as Avalonia inlines without embedding an editor control
• Custom Inlines — Override rendering by providing your own InlineCollection
• Monospace Font — Defaults to Cascadia Code, Consolas, Courier New, monospace

Dependencies

• Huskui.Avalonia — Core control library (required)
• TextMateSharp.Grammars — Bundled grammars and themes
