1 month ago This pull request adds a new report_missing method to the crepr.py file. The method is implemented as a Typer command that analyzes Python files to identify and count classes without a __repr__ method. It provides a summary report for each file, highlighting classes missing the __repr__ method.

A new command function report_missing has been introduced in the application. This function analyzes a list of file paths to identify classes that do not implement a __repr__ method. It retrieves class information, checks for the presence of the __repr__ method, and reports the count and names of classes lacking this method. Additional helper functions enhance modularity and error handling.

crepr/crepr.py |
Added method report_missing(files: Annotated[list[pathlib.Path], file_arg]) -> None to analyze specified files for classes without a __repr__ method. Introduced several helper functions for modularity and error handling. |
__repr__, as described in the issue.crepr/crepr.py include the addition of new command functions and enhancements to the CLI, which are directly related to the new report_missing function introduced in the main PR.Review effort [1-5]: 4
In the land of code where rabbits hop,
A method was added, now classes won’t flop.
Withreport_missing, we’ll find every case,
No more lost classes in the__repr__race!
Hooray for the changes, let’s give them a cheer,
For clearer code paths, we hold so dear! 🐇✨

| ⚡ Key issues to review Code Duplication The `report_missing` function duplicates some logic from other parts of the codebase, such as getting the module and iterating through class members. Consider refactoring common operations into separate functions. Error Handling The function doesn't handle potential exceptions that might occur when reading files or inspecting modules. Consider adding try-except blocks for robustness. |

| Error handling |
✅ Add error handling for file operations and module imports___Suggestion Impact:The suggestion to add error handling for file operations was implemented. The commit added try-except blocks around the module loading and class inspection processes, handling specific exceptions and providing error messages. code diff: ```diff + try: + # Attempt to load the module + module = get_module(file_path) + except ModuleNotFoundError: + # Handle the case where __init__.py is missing or the module cannot be loaded + typer.secho( + f"Error: Couldn't load module '{file_path}'.

| Enhancement |
✅ Simplify the loop for creating no_repr_classes using a list comprehension___Suggestion Impact:The commit refactored the code to use list comprehensions for extracting classes and filtering those without a __repr__ method, aligning with the suggestion's intent. code diff: ```diff +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 AttributeError as e: + raise AttributeError(f"Error processing classes in {file_path}: {e}") + + +def filter_no_repr(classes): + """Filter out classes without a __repr__ method.""" + return [ + obj.__name__ for obj in classes + if get_repr_source(obj)[1] == -1 ```no_repr_classes list. This can make the code more concise and potentially more efficient.** [crepr/crepr.py [366-372]](https://github.com/cleder/crepr/pull/52/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R366-R372) ```diff -for _, obj in inspect.getmembers(module, inspect.isclass): - if not is_class_in_module(obj, module): - continue - _, lineno = get_repr_source(obj) - if lineno == -1: - no_repr_classes.append((lineno, obj.__name__)) - class_count += 1 +class_members = inspect.getmembers(module, inspect.isclass) +no_repr_classes = [(get_repr_source(obj)[1], obj.__name__) + for _, obj in class_members + if is_class_in_module(obj, module) and get_repr_source(obj)[1] == -1] +class_count = len([obj for _, obj in class_members if is_class_in_module(obj, module)]) ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 7Why: The suggestion improves code conciseness and readability by using list comprehensions, which is a more Pythonic approach. However, it doesn't address a critical issue, so the score is moderate. | 7 |
Use enumerate() to simplify the loop that prints class names without __repr__ methods___ **Consider usingenumerate() in the loop that prints class names without __repr__ methods. This can simplify the code by providing both the index and the class name directly.** [crepr/crepr.py [380-381]](https://github.com/cleder/crepr/pull/52/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R380-R381) ```diff -for lineno, class_name in no_repr_classes: - typer.echo(f"{file_path}: {class_name}") +for i, (_, class_name) in enumerate(no_repr_classes, 1): + typer.echo(f"{file_path}: {i}. {class_name}") ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 6Why: Using `enumerate()` simplifies the loop and improves readability by directly providing an index, but it is not a critical change, so it receives a moderate score. | 6 | |

✅ Use an f-string for the entire output message instead of string concatenation___Suggestion Impact:The suggestion to use an f-string for the output message was implemented in the refactored code. code diff: ```diff + typer.secho( + f"In module '{file_path}': {count_no_repr} class(es) don't have a __repr__ method:", + fg="yellow" ```This can make the code more readable and potentially more efficient.** [crepr/crepr.py [375-379]](https://github.com/cleder/crepr/pull/52/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R375-R379) ```diff typer.secho( - f"In module '{file_path}': {len(no_repr_classes)} class(es) " - "don't have a __repr__ method:", + f"In module '{file_path}': {len(no_repr_classes)} class(es) don't have a __repr__ method:", fg="yellow" ) ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 5Why: The suggestion enhances code readability by using f-strings, which are more efficient and cleaner than string concatenation. This is a minor improvement, hence a moderate score. | 5 |

| Performance |
Use a generator expression instead of a list for better memory efficiency___ **Consider using a generator expression instead of a list comprehension forno_repr_classes to improve memory efficiency, especially for large modules with many classes.** [crepr/crepr.py [363-372]](https://github.com/cleder/crepr/pull/52/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R363-R372) ```diff -no_repr_classes = [] +no_repr_classes = ( + (lineno, obj.__name__) + for _, obj in inspect.getmembers(module, inspect.isclass) + if is_class_in_module(obj, module) + and (_, lineno := get_repr_source(obj))[1] == -1 +) +class_count = sum(1 for _ in inspect.getmembers(module, inspect.isclass) if is_class_in_module(_, module)) -for _, obj in inspect.getmembers(module, inspect.isclass): - if not is_class_in_module(obj, module): - continue - _, lineno = get_repr_source(obj) - if lineno == -1: - no_repr_classes.append((lineno, obj.__name__)) - class_count += 1 - ``` Suggestion importance[1-10]: 7Why: The suggestion to use a generator expression can improve memory efficiency, which is beneficial for large modules. However, it slightly complicates the code and the performance gain may not be significant for smaller modules. | 7 |
| Maintainability |
Use a more descriptive variable name for better code readability___ **Consider using a more descriptive variable name instead of_ for the first item in the tuple unpacking of get_repr_source(obj) to improve code readability.**
[crepr/crepr.py [369-371]](https://github.com/cleder/crepr/pull/52/files#diff-abcd7c4a2773c8234cdc05070d0abd10b0245a1a15f470288240c6d3a108f576R369-R371)
```diff
-_, lineno = get_repr_source(obj)
+repr_source, lineno = get_repr_source(obj)
if lineno == -1:
no_repr_classes.append((lineno, obj.__name__))
```
Suggestion importance[1-10]: 6Why: Using a more descriptive variable name enhances code readability and maintainability, although it is a minor improvement. | 6 |
