在运行时导出自定义EditorFormatDefinition

Question

在我构建的Visual Studio扩展中,我需要在Visual Studio编辑器中突出显示方法调用.例如:

我想使用HSV颜色根据唯一调用的数量来划分色谱.

如果我将每种颜色导出为自己的EditorFormatDefinition,我可以实现突出显示:

[Export(typeof(EditorFormatDefinition))]
[ClassificationType(ClassificationTypeNames = "red-background")]
[Name("red-background")]
[UserVisible(true)]
[Order(After = Priority.High)]
public sealed class RedBackground : ClassificationFormatDefinition
{
    public RedBackground()
    {
        DisplayName = "red-background";
        BackgroundColor = Colors.Red;
    }
}

但是,这需要我手动设置我想提前使用的所有颜色.有没有办法EditorFormatDefinitions在运行时导出？

IContentTypeRegistryService中的某些注册表,IClassificationTypeRegistryService允许在运行时创建新的内容类型和分类.是否存在类似的API EditorFormatDefinitions.

或者,是否可以EditorFormatDefinition在Visual Studio中动态MEF导出？

解决方案是使用IClassificationFormatMapServiceto来请求特定的IClassificationFormatMap.然后我们可以请求TextFormattingRunProperties并创建一组新的文本格式属性,我们可以将其添加到IClassificationFormatMap.

//No reason to use identifier, just a default starting point that works for me.
var identiferClassificationType = registryService.GetClassificationType("identifier");
var classificationType = registryService.CreateClassificationType(name, SpecializedCollections.SingletonEnumerable(identiferClassificationType));
var classificationFormatMap = ClassificationFormatMapService.GetClassificationFormatMap(category: "text");
var identifierProperties = classificationFormatMap
    .GetExplicitTextProperties(identiferClassificationType);

//Now modify the properties
var color = System.Windows.Media.Colors.Yellow;
var newProperties = identifierProperties.SetForeground(color);
classificationFormatMap.AddExplicitTextProperties(classificationType, newProperties);

//Now you can use or return classificationType...
