RoslynPad.Editor.Avalonia

A Roslyn-powered code editor control for Avalonia, built on AvaloniaEdit. Provides completion, diagnostics, signature help, quick actions, and code folding out of the box.

Key Types

RoslynCodeEditor

The main editor control. Extends CodeTextEditor with full Roslyn integration.

<Window xmlns:editor="clr-namespace:RoslynPad.Editor;assembly=RoslynPad.Editor.Avalonia">
 <editor:RoslynCodeEditor x:Name="Editor"
 FontFamily="Consolas" />
</Window>

var documentId = await editor.InitializeAsync(
 host,
 new ClassificationHighlightColors(),
 workingDirectory,
 documentText: string.Empty,
 SourceCodeKind.Script);

Properties: IsCodeFoldingEnabled, IsBraceCompletionEnabled, ContextActionsIcon

ClassificationHighlightColors

Default syntax highlighting colors with configurable brushes.

Brushes: TypeBrush, MethodBrush, KeywordBrush, StringBrush, CommentBrush, BraceMatchingBrush, and more.

ThemeClassificationColors

Creates syntax highlighting from a VS Code Theme (from the RoslynPad.Themes package).

var theme = await themeReader.ReadThemeAsync(themeFile, ThemeType.Dark);
var colors = new ThemeClassificationColors(theme);
await editor.InitializeAsync(host, colors, workingDirectory, "", SourceCodeKind.Script);

AvalonEditTextContainer

Bridges AvaloniaEdit's TextDocument to Roslyn's SourceTextContainer.

CreatingDocumentEventArgs

Raised during initialization. Use to customize document creation (e.g., for REPL chaining):

editor.CreatingDocument += (sender, args) =>
{
 args.DocumentId = host.AddRelatedDocument(
 previousDocumentId,
 new DocumentCreationArgs(args.TextContainer, workingDirectory,
 SourceCodeKind.Script, args.TextContainer.UpdateText));
};
