EasyStyledProperty# Roslyn Source Generators Sample

用于 Avalonia 的 StyledProperty 源生成器,让您通过简单的特性标注自动生成 StyledProperty 和属性代码。A set of three projects that illustrates Roslyn source generators. Enjoy this template to learn from and modify source generators for your own needs.

安装## Content

SourceGenerators

dotnet add package EasyStyledProperty**You must build this project to see the result (generated code) in the IDE.**

• SampleSourceGenerator.cs: A source generator that creates C# classes based on a text file (in this case, Domain Driven Design ubiquitous language registry).

使用方法- SampleIncrementalSourceGenerator.cs: A source generator that creates a custom report based on class properties. The target class should be annotated with the Generators.ReportAttribute attribute.

1. 在您的 Avalonia 控件类上添加特性### SourceGenerators.Sample

A project that references source generators. Note the parameters of ProjectReference in SourceGenerators.Sample.csproj, they make sure that the project is referenced as a set of source generators.

using EasyStyledProperty;### SourceGenerators.Tests Unit tests for source generators. The easiest way to develop language-related features is to start with unit tests. [StyledProperty("Text", typeof(string), "默认文本")] [StyledProperty("IsEnabled", typeof(bool), true)]## How To? [StyledProperty("FontSize", typeof(double), 14.0)]### How to debug? public partial class MyControl : AvaloniaObject- Use the [launchSettings.json](Properties/launchSettings.json) profile. {- Debug tests. // 源生成器会自动生成: // - public static readonly StyledProperty<string> TextProperty### How can I determine which syntax nodes I should expect? // - public string Text { get; set; }Consider using the Roslyn Visualizer toolwindow, witch allow you to observe syntax tree. // - public static readonly StyledProperty<bool> IsEnabledProperty // - public bool IsEnabled { get; set; }### How to learn more about wiring source generators? // - public static readonly StyledProperty<double> FontSizePropertyWatch the walkthrough video: [Let’s Build an Incremental Source Generator With Roslyn, by Stefan Pölz](https://youtu.be/azJm_Y2nbAI) // - public double FontSize { get; set; }The complete set of information is available in [Source Generators Cookbook](https://github.com/dotnet/roslyn/blob/main/docs/features/source-generators.cookbook.md). }

2. 高级选项

[StyledProperty("Command", typeof(ICommand), null, BindsTwoWayByDefault = true, PropertyChangedCallback = "OnCommandChanged", CoerceCallback = "CoerceCommand")] public partial class MyButton : Button { private static void OnCommandChanged(AvaloniaObject obj, AvaloniaPropertyChangedEventArgs args) { // 属性变更回调 } private static object CoerceCommand(AvaloniaObject obj, object value) { // 值强制转换 return value; } }
