Monaco 中的 TypeDefinitionProvider 和 ImplementationProvider、DefinitionProvider 类似，右键点击变量名称，现在 “选择转到类型定义”， 跳到指定位置。

通过 registerTypeDefinitionProvider 添加 TypeDefinitionProvider 处理方法

实现 provideTypeDefinition 并返回 Definition

Definition 中定义了跳转位置

代码实现如下

export function typeDefinitionProvider(
  editor: monacoEditor.editor.IStandaloneCodeEditor,
  monaco: typeof monacoEditor
) {
  monaco.languages.registerTypeDefinitionProvider("mySpecialLanguage", {
    provideTypeDefinition(model, position, token) {
      const word = model.getWordAtPosition(position);
      if (!word) {
        return null;
      }
      const text = model.getValue();
      const regex = new RegExp(`\\b${word.word}\\b`, 'g');
      let match;
      let firstOccurrenceRange: monacoEditor.Range | null = null;
      while ((match = regex.exec(text)) !== null) {
        const start = model.getPositionAt(match.index);
        const end = model.getPositionAt(match.index + word.word.length);
        firstOccurrenceRange = new monaco.Range(start.lineNumber, start.column, end.lineNumber, end.column);
        break;
      }
  
      if (firstOccurrenceRange) {
        return [
          {
            uri: model.uri,
            range: firstOccurrenceRange,
          }
        ];
      }

      // Provide a dummy type definition as an example
      const typeDefinitionRange = new monaco.Range(position.lineNumber, word.startColumn, position.lineNumber, word.endColumn);
  
      return [
        {
          uri: model.uri,
          range: typeDefinitionRange,
        }
      ];
    }
  })
}
