Meanwhile I noticed our linter There is another issue: the import block seems to have inconsistent format across files, some have two blank lines between the code body, while some have only one? |

- 5-5: The import statement for
_load_pmg_settingsis correctly added and follows Python's best practices for import organization.- 2-14: > 📝 NOTE
This review was outside the diff hunks, and no overlapping diff hunk was found. Original lines [17-45]
The test function
test_load_settingsis well-written, covering a comprehensive range of scenarios for loading settings and correctly usingmonkeypatchfor test isolation.pymatgen/io/ase.py (1)
- 34-39: The changes within the
TYPE_CHECKINGblock, including the addition of type hint imports forAny,ArrayLike, andSiteCollection, are correctly implemented and follow best practices for managing type hints.pymatgen/io/lammps/utils.py (2)
- 21-24: Moving the
pybelimport before theTYPE_CHECKINGblock is a strategic change that ensurespybelis available for runtime functionality. Please verify that this change does not negatively impact the runtime behavior of the module.- 26-29: The addition of the
TYPE_CHECKINGblock, including the import ofSequenceandArrayLike, follows best practices for managing type hints and enhances code readability and maintainability.pymatgen/vis/structure_vtk.py (6)
- 27-29: The removal of the
TYPE_CHECKINGblock and re-importingSequencelater in the file could potentially impact type checking and code clarity. Ensure that this change aligns with the project's guidelines on handling type hints and imports for type checking. IfSequenceis used only for type annotations and not executed at runtime, keeping it within aTYPE_CHECKINGblock could be more efficient and clearer.- 16-21: > 📝 NOTE

Consider adding a module-level docstring that provides a brief overview of the module's purpose and functionality. This enhances code readability and maintainability by giving future developers a quick understanding of the module's role within the project.

In the
__init__method, consider validating the input arguments to ensure they meet expected types or constraints. For example,element_color_mappingshould be validated to ensure it's eitherNoneor a dictionary with the correct structure. Adding input validation can prevent runtime errors and improve code robustness.

The
rotate_viewmethod adjusts the camera view based on the axis index and angle. Consider adding error handling or validation for theaxis_indargument to ensure it falls within the expected range (0, 1, or 2). This can prevent unexpected behavior if an invalid axis index is provided.

This review was outside the diff hunks, and no overlapping diff hunk was found. Original lines [146-172]
In the
write_imagemethod, theimage_formatargument is used to determine the writer type. Consider using a more flexible approach that allows for additional image formats without requiring modifications to the method's logic. For example, a dictionary mapping supported formats to their corresponding VTK writer classes could simplify adding support for new formats in the future.

The
set_structuremethod in theMultiStructuresVisclass overrides the method from theStructureVisclass. Ensure that the method's extended functionality is well-documented, and consider adding comments to clarify the reasons for overriding and the additional capabilities provided.pymatgen/io/vasp/outputs.py (10)

The
fft_meshmethod in theWavecarclass efficiently generates an FFT mesh for discrete Fourier transform of the wavefunction. It provides options for scaling the FFT grid and shifting the zero frequency component, which are important for accurate real-space evaluation of the wavefunction. This method is a key component for wavefunction analysis in real space.

i would stick to single blank line above if TYPE_CHECKING:. would be nice if ruff enforced this
There was a problem hiding this comment.
I tried to remove the extra blank line but ruff added it back. ruff seem to have a weird interaction with if TYPE_CHECKING: for some reason?

i see, no worries. not that important

Thanks for reviewing. I guess for such issues we'd better wait until ruff has some solution (or perhaps already has but we don't know about), and run ruff to fix all issues.
