Walkthrough

The pull request introduces several modifications across multiple files in the quizgen module. In src/quizgen/quizgen.py, the main function has been updated to eliminate the use of argparse, opting instead for manual command-line argument parsing through sys.argv. A new function, print_help, has been added to assist users by providing usage instructions when no command is specified. The command handling has been streamlined to directly evaluate the first argument from sys.argv, and the check for the batch processing flag has been adjusted to look for "--batch" within sys.argv. The command construction has also been revised to include all arguments while excluding the --batch flag.

In the scripts located in src/quizgen/scripts/, new import statements for the os module have been added to facilitate dynamic path construction for various scripts. Specifically, the paths for convert_questions.py, generate_questions.py, and generate_embeddings.py are now built using os.path.join and os.path.dirname(__file__), replacing hardcoded paths. Additionally, minor indentation corrections have been made in conditional blocks that check for existing output files, ensuring proper alignment of the continue statements. No changes have been made to the declarations of exported or public entities in the script files.

src/quizgen/scripts/convert_questions_batch.py (1)

Line range hint 1-58: Suggestion: Update PR description and title

The changes in this file improve the script's portability and robustness, which are valuable improvements. However, they don't directly align with the PR objective of "significantly improve CLI" as stated in the PR title.

Consider updating the PR title and description to more accurately reflect the nature of these changes. For example:

• Title: "Improve script portability and robustness"
• Description: "This PR enhances the convert_questions_batch.py script by improving its portability across different operating systems and making it more robust when run from various locations."

This will help reviewers and future maintainers understand the purpose and impact of these changes more clearly.

src/quizgen/scripts/generate_embeddings_batch.py (2)

28-32: Approve: Improved path handling, but consider a small enhancement.

The use of os.path.join and os.path.dirname(__file__) to construct the script_path is a good improvement. It makes the script more portable and robust, aligning with the objective of improving the CLI.

However, to ensure compatibility when the script is run as a module (using the -m flag), consider using __file__ directly:

script_path = os.path.join(os.path.dirname(os.path.abspath(__file__)), "generate_embeddings.py")

This change ensures the correct path is used regardless of how the script is executed.

---

Line range hint 1-65: Consider additional CLI improvements to align with PR objective.

While the current changes improve the script's robustness, they don't significantly enhance the CLI interface itself. To better align with the PR objective of "significantly improve CLI", consider the following suggestions:

1. Add more informative error messages for common failure scenarios.
2. Implement logging with different verbosity levels (e.g., DEBUG, INFO, WARNING).
3. Add a --version argument to display the script version.
4. Provide a --dry-run option to show what would be processed without actually generating embeddings.
5. Allow specifying a custom name for the output files instead of always using .npy.

These enhancements would provide users with more control and information, significantly improving the CLI experience.

src/quizgen/quizgen.py (2)

24-27: Consider the trade-offs of removing argparse.

While simplifying the command-line interface by removing the argparse dependency, this change comes with some trade-offs:

Pros:

• Simplified code structure
• Direct control over argument parsing

Cons:

• Loss of automatic help generation and argument validation
• Reduced flexibility for adding new commands or options
• Potential for errors in manual argument parsing

Consider whether the benefits outweigh the costs in terms of maintainability and extensibility.

---

1-61: Overall CLI improvement with some concerns.

The changes significantly simplify the CLI implementation by removing the argparse dependency. This aligns with the PR objective of improving the CLI. However, there are some concerns:

1. Reduced robustness in argument parsing and validation.
2. Potential difficulties in maintaining and extending the CLI in the future.
3. Loss of some user-friendly features provided by argparse.

Consider addressing these concerns to ensure that the CLI improvement doesn't come at the cost of long-term maintainability and user experience.

src/quizgen/scripts/generate_questions_batch.py (2)

30-34: Improved script path handling.

The change to use os.path.join and os.path.dirname(__file__) for constructing the script path is a significant improvement. It makes the script more robust and portable, aligning well with the PR objective of improving the CLI.

Consider using pathlib.Path for consistency with the rest of the script:

script_path = pathlib.Path(__file__).parent / "generate_questions.py"

This approach is more consistent with the use of pathlib elsewhere in the script and provides a cleaner, more Pythonic way of handling paths.

---

Line range hint 1-89: Suggestions for future improvements.

The changes made have improved the script's robustness, which aligns well with the PR objective. For future iterations, consider the following enhancements:

1. Implement more robust error handling, especially around the subprocess.run call.
2. Add logging to provide better visibility into the script's execution, particularly for batch operations.
3. Consider using a configuration file for default values (like model names) to make the script more maintainable.

These suggestions are not critical for this PR but could further improve the CLI in the future.

src/quizgen/scripts/convert_questions_batch.py (2)

5-5: LGTM: Import of os module

The addition of the os module import is appropriate and necessary for the changes made in the script. It's correctly placed with other imports at the top of the file.

---

28-28: Approve: Improved script path construction

The new method of constructing the script_path using os.path.join(os.path.dirname(__file__), "convert_questions.py") is a significant improvement. It makes the script more robust and portable across different operating systems and when run from various locations.

However, this change doesn't seem to directly relate to the PR objective of "significantly improve CLI". Consider updating the PR description to accurately reflect the nature of these changes, such as "Improve script portability and robustness".

To ensure the script works as expected with the new path construction, you can run the following verification:

This script changes to the directory containing convert_questions_batch.py, runs it with the --help flag, then changes to the root directory and runs it again. If both executions succeed, it confirms that the script can be run from different locations.

src/quizgen/scripts/generate_embeddings_batch.py (1)

5-5: LGTM: Import of os module is appropriate.

The addition of the os module import is necessary for the subsequent changes in the file and follows good import practices.

src/quizgen/quizgen.py (2)

6-20: LGTM: Clear and informative help function added.

The new print_help() function provides clear and concise information about the CLI usage, covering all available commands and the batch processing option. The formatting is consistent and easy to read, which will improve the user experience.

---

58-61: Efficient command construction, but consider error handling.

The use of list comprehension for command construction is efficient and clear. However, consider adding error handling for cases where required arguments might be missing.

To verify the robustness of the command construction, we can check for proper argument handling in the subscripts:
