Avalona下AvaloniaEdit的使用

安装3个包：

Install-Package Avalonia.AvaloniaEdit
Install-Package AvaloniaEdit.TextMate
Install-Package TextMateSharp.Grammars

在App.xaml的<Application.Styles>下增加：

<StyleInclude Source="avares://AvaloniaEdit/Themes/Fluent/AvaloniaEdit.xaml" />

前台代码：

<Window xmlns="https://github.com/avaloniaui"
        ...
        xmlns:AvaloniaEdit="clr-namespace:AvaloniaEdit;assembly=AvaloniaEdit"
        ...>
  ...
  <AvaloniaEdit:TextEditor Text="Hello AvaloniaEdit!"
                           ShowLineNumbers="True"
                           FontFamily="Cascadia Code,Consolas,Menlo,Monospace"/>
  ...
</Window>

后台代码：

//First of all you need to have a reference for your TextEditor for it to be used inside AvaloniaEdit.TextMate project.
var _textEditor = this.FindControl<TextEditor>("Editor");

//Here we initialize RegistryOptions with the theme we want to use.
var  _registryOptions = new RegistryOptions(ThemeName.DarkPlus);

//Initial setup of TextMate.
var _textMateInstallation = _textEditor.InstallTextMate(_registryOptions);

//Here we are getting the language by the extension and right after that we are initializing grammar with this language.
//And that's all 😀, you are ready to use AvaloniaEdit with syntax highlighting!
_textMateInstallation.SetGrammar(_registryOptions.GetScopeByLanguageId(_registryOptions.GetLanguageByExtension(".cs").Id));
