Summary of Changes

Hello @Col0ring, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the modelscope_studio.components.pro library by adding a powerful MonacoEditor component, complete with a diff editing mode. This integration brings advanced code editing capabilities to Gradio applications, offering features like syntax highlighting, code completion, and diff viewing. The changes span both backend Python definitions and frontend Svelte/React implementations, ensuring a seamless and well-documented user experience.

Highlights

  • New MonacoEditor Component: Introduced a new MonacoEditor component and its DiffEditor variant within the modelscope_studio.components.pro library, providing a rich code editing experience.
  • Frontend Integration: Integrated the Monaco Editor into the frontend using @monaco-editor/react, with support for both local and CDN loading modes.
  • Comprehensive Documentation and Examples: Added extensive documentation in both English and Chinese, along with multiple examples demonstrating basic usage, diff editing, customization options, and JavaScript-based configurations for the new editor.
  • Event Handling: The new editor components support mount, change, and validate events, allowing for dynamic interaction and validation within Gradio applications.

Code Review

This pull request introduces a new MonacoEditor component and its diff editor variant. The implementation looks good overall, with both Python backend and Svelte/React frontend parts. I've found a few issues related to documentation, code design, and a potential bug in the React component. My review includes suggestions to add docstrings, provide example values, refactor a circular import, fix inconsistencies, correct a typo in the documentation, and resolve a stale closure bug in the diff editor component.

The local import from .. import ModelScopeProMonacoEditor inside the __init__ method is used to work around a circular dependency. This is a code smell and can lead to confusion and maintenance issues. A better approach would be to refactor the code to break the circular dependency. For example, you could move the shared LOADER configuration to a separate file that both modules can import from without creating a cycle.

Example refactor:

  1. Create a new file backend/modelscope_studio/components/pro/monaco_editor/config.py with the LOADER config.
  2. Import LOADER from config.py in both monaco_editor/__init__.py and monaco_editor/diff_editor/__init__.py.

The onChange and onValidate props are used inside handleEditorMount, which is only called once when the component mounts. This creates a stale closure, meaning if these props change, the editor will continue to use the old functions from the initial render. To fix this, you should wrap them with the useFunction hook, similar to how beforeMount and afterMount are handled.

    const beforeMountFunction = useFunction(beforeMount);
    const afterMountFunction = useFunction(afterMount);
    const onChangeFunction = useFunction(onChange);
    const onValidateFunction = useFunction(onValidate);
    const disposablesRef = useRef<IDisposable[]>([]);
    const editorRef = useRef<editor.IStandaloneDiffEditor | null>(null);
    const [isEditorReady, setIsEditorReady] = React.useState(false);
    const [value, setValue] = useValueChange({
      onValueChange,
      value: valueProp,
    });
    const handleEditorMount: MonacoDiffEditorProps['onMount'] = (
      editor,
      monaco
    ) => {
      editorRef.current = editor;
      if (isNumber(line)) {
        editor.revealLine(line);
      }
      setIsEditorReady(true);
      const modifiedEditor = editor.getModifiedEditor();
      const mountDisposable = modifiedEditor.onDidChangeModelContent((e) => {
        const newValue = modifiedEditor.getValue();
        setValue(newValue);
        onChangeFunction?.(newValue, e);
      });

      const validateDisposable = monaco.editor.onDidChangeMarkers((uris) => {
        const editorUri = modifiedEditor.getModel()?.uri;
        if (editorUri) {
          const currentEditorHasMarkerChanges = uris.find(
            (uri) => uri.path === editorUri.path
          );
          if (currentEditorHasMarkerChanges) {
            const markers = monaco.editor.getModelMarkers({
              resource: editorUri,
            });
            onValidateFunction?.(markers);
          }
        }
      });
      disposablesRef.current.push(mountDisposable, validateDisposable);
    };

The docstring for the ModelScopeProMonacoEditor class is empty. Please add a comprehensive docstring explaining what the component does, its parameters, and how to use it. This is important for maintainability and for other developers to understand the component.

The example_value method currently returns None. To improve usability and testing, it's better to provide a meaningful example value, such as a sample code snippet string.

The loading parameter has a default value of None, which is inconsistent with the MonacoEditor component where it defaults to "Editor is loading...". For consistency and better user experience, it's recommended to use the same default value.

loading: str | None = "Editor is loading...",

There is a typo in the property name modified_Language. It should be modified_language to match the actual parameter name in the component's implementation.
