Lizerium.Localization.Ai.Analyzer

Roslyn analyzer and AI CodeFix provider for Lizerium.Localization.Toolkit.

The analyzer detects localizable C# text and offers a CodeFix that asks the AI localization service for translations, writes keys to Strings.en.resx and Strings.ru.resx, and replaces source text with generated localization API calls.

CodeFix

Use Ctrl + . -> Create localization key (AI).

For a plain string:

var text = "Hello World";

the CodeFix creates a key such as MainWindow_Render_Text1, writes AI-generated en and ru values, and replaces the literal with:

var text = L.MainWindow.Render.Text1();

For an interpolated string:

var details = $"Log directory: {AppContext.BaseDirectory} | {5}";

the CodeFix stores the resource value as Log directory: {0} | {1} and replaces the source with:

var details = L.MainWindow.Render.Text2(AppContext.BaseDirectory, 5);

If the local AI service is unavailable or returns incomplete data, the CodeFix falls back to the original source text so the project remains compilable.

AI Server Configuration

The analyzer is distributed through the NuGet/toolkit package, so it cannot use a normal application settings file. Configure its AI servers with environment variables before starting Visual Studio:

LIZERIUM_OLLAMA_URL=http://localhost:11434
LIZERIUM_OLLAMA_MODEL=qwen2.5:7b
LIZERIUM_OLLAMA_GENERATE_ENDPOINT=/api/generate
LIZERIUM_LIBRETRANSLATE_URL=http://localhost:5000
LIZERIUM_AI_TIMEOUT_SECONDS=30

If variables are not set, these same values are used as defaults. Lizerium.AI.LocalizationAssistant.Core also exposes AiLocalizationOptions for direct NuGet usage from custom tools or applications.

XAML

Plain Roslyn analyzers do not provide native quick actions inside the Visual Studio XAML editor. XAML conversion is exposed through Lizerium.Localization.Core.XamlLocalizationService and the WPF {loc:Loc Key} markup extension. A VSIX or editor command can reuse that service to convert selected XAML text and write RESX keys.
