The pull request introduces a new command, report_missing, to the crepr module, which identifies and reports classes that do not implement a __repr__ method in specified source files. It includes several helper functions to process files, load modules, extract classes, filter those without a __repr__, and report the results. This enhancement allows users to easily find classes lacking a __repr__, improving the module's usability in code quality checks.
| File | Change Summary |
|---|---|
| crepr/crepr.py | Added methods: report_missing, process_file, load_module, extract_classes, filter_no_repr, report_results. |
__repr__, which is directly addressed by the newly added report_missing command in this pull request.🐰 In the code where classes dwell,
A__repr__gap we know too well.
Withreport_missing, we now can see,
Which classes lack their identity!
So hop along, let's tidy up,
And fill the code with a cheerful cup! 🍵

| ⚡ Key issues to review Error Handling The error handling in the `load_module` and `extract_classes` functions may lead to silent failures. The `CreprError` is caught and printed, but the function doesn't return or raise an exception, potentially causing issues in the calling function. Code Duplication The error handling pattern is repeated in multiple functions. Consider creating a decorator or utility function to handle these errors consistently across the module. Possible Performance Issue The `filter_no_repr` function calls `get_repr_source` for each class, which might be inefficient for large numbers of classes. Consider caching the results or optimizing this operation. |

| Error handling |
✅ Propagate errors to the caller for centralized error handling instead of handling them locally___Suggestion Impact:The suggestion to propagate errors instead of handling them locally was implemented. The load_module function now returns None if an error occurs, and the extract_classes function no longer handles errors locally. code diff: ```diff def process_file(file_path: pathlib.Path) -> None: """Process a single file and report classes without a __repr__ method.""" module = load_module(file_path) - classes = extract_classes(module, file_path) + if module is None: + typer.secho(f"Error: Could not load module from {file_path}", fg="red", err=True) + return + + classes = extract_classes(module) no_repr_classes = filter_no_repr(classes) report_results(file_path, classes, no_repr_classes) - -def load_module(file_path: pathlib.Path): +def load_module(file_path: pathlib.Path) -> Optional[ModuleType]: """Load a module from a given file path.""" try: return get_module(file_path) except CreprError as e: typer.secho(e.message, fg="red", err=True) - - -def extract_classes(module, file_path: pathlib.Path): + return None + +def extract_classes(module: ModuleType) -> List[Type]: """Extract classes from a module.""" - try: - return [ - obj - for _, obj in inspect.getmembers(module, inspect.isclass) - if is_class_in_module(obj, module) - ] - except CreprError as e: - typer.secho(e.message, fg="red", err=True) - - -def filter_no_repr(classes): + return [ + obj for _, obj in inspect.getmembers(module, inspect.isclass) + if is_class_in_module(obj, module) + ] ```load_module and extract_classes functions, consider raising the CreprError instead of handling it immediately to allow for centralized error handling.** [crepr/crepr.py [397-413]](https://github.com/cleder/crepr/pull/53/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R397-R413) ```diff def load_module(file_path: pathlib.Path): """Load a module from a given file path.""" - try: - return get_module(file_path) - except CreprError as e: - typer.secho(e.message, fg="red", err=True) + return get_module(file_path) def extract_classes(module, file_path: pathlib.Path): """Extract classes from a module.""" - try: - return [ - obj for _, obj in inspect.getmembers(module, inspect.isclass) - if is_class_in_module(obj, module) - ] - except CreprError as e: - typer.secho(e.message, fg="red", err=True) + return [ + obj for _, obj in inspect.getmembers(module, inspect.isclass) + if is_class_in_module(obj, module) + ] ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 9Why: Centralizing error handling by propagating errors to the caller improves code maintainability and allows for more consistent error management across the application. | 9 |

✅ Simplify error handling by propagating exceptions to the caller___Suggestion Impact:The suggestion to propagate exceptions instead of handling them locally was implemented. The load_module and extract_classes functions were modified to remove local exception handling and propagate exceptions to the caller. code diff: ```diff -def load_module(file_path: pathlib.Path): +def load_module(file_path: pathlib.Path) -> Optional[ModuleType]: """Load a module from a given file path.""" try: return get_module(file_path) except CreprError as e: typer.secho(e.message, fg="red", err=True) - - -def extract_classes(module, file_path: pathlib.Path): + return None + +def extract_classes(module: ModuleType) -> List[Type]: """Extract classes from a module.""" - try: - return [ - obj - for _, obj in inspect.getmembers(module, inspect.isclass) - if is_class_in_module(obj, module) - ] - except CreprError as e: - typer.secho(e.message, fg="red", err=True) - - -def filter_no_repr(classes): + return [ + obj for _, obj in inspect.getmembers(module, inspect.isclass) + if is_class_in_module(obj, module) + ] ```load_module and extract_classes functions, consider raising the CreprError instead of handling it locally, as it's already being caught in the calling function.** [crepr/crepr.py [397-413]](https://github.com/cleder/crepr/pull/53/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R397-R413) ```diff def load_module(file_path: pathlib.Path): """Load a module from a given file path.""" - try: - return get_module(file_path) - except CreprError as e: - typer.secho(e.message, fg="red", err=True) + return get_module(file_path) def extract_classes(module, file_path: pathlib.Path): """Extract classes from a module.""" - try: - return [ - obj for _, obj in inspect.getmembers(module, inspect.isclass) - if is_class_in_module(obj, module) - ] - except CreprError as e: - typer.secho(e.message, fg="red", err=True) + return [ + obj for _, obj in inspect.getmembers(module, inspect.isclass) + if is_class_in_module(obj, module) + ] ``` Suggestion importance[1-10]: 9Why: Propagating exceptions to the caller simplifies the code and avoids redundant error handling, which is already managed in the calling function.
