PR Code Suggestions

Category	Suggestions
Enhancement	Enhance the coordinate function to accept additional arguments dynamically. **To ensure that the coordinate partial function is reusable and customizable for different strategies, consider adding kwargs to allow passing additional arguments such as min_value and max_value directly. This enhancement will make the function more flexible and reduce redundancy in specifying these values in multiple places. pygeoif/hypothesis/strategies.py [43-48] coordinate = partial( st.floats, allow_infinity=False, allow_nan=False, allow_subnormal=False, width=32, + **kwargs, # Allows passing additional arguments dynamically )
	Add validation for min_xyz and max_xyz in the Srs dataclass. For the Srs dataclass, consider adding a method to validate the min_xyz and max_xyz attributes to ensure they are within reasonable bounds. This validation can prevent potential errors when generating coordinates based on these values. pygeoif/hypothesis/strategies.py [52-69] @dataclass(frozen=True) class Srs: name: str min_xyz: Tuple[Optional[float], Optional[float], Optional[float]] max_xyz: Tuple[Optional[float], Optional[float], Optional[float]] + def __post_init__(self): + # Example validation logic + if self.min_xyz[0] is not None and self.max_xyz[0] is not None: + if self.min_xyz[0] > self.max_xyz[0]: + raise ValueError("Minimum X value cannot be greater than maximum X value.") +
	Set default max_points to reflect minimum valid geometry in line_strings and linear_rings. To ensure that the max_points parameter in line_strings and linear_rings functions adheres to their geometric definitions, consider adding a default value that reflects the minimum required points for a valid geometry. For line_strings, a minimum of 2 points is required, and for linear_rings, at least 4 points are needed to form a valid ring. pygeoif/hypothesis/strategies.py [257-263] def line_strings( draw: st.DrawFn, *, - max_points: Optional[int] = None, + max_points: int = 2, # Default to the minimum valid value srs: Optional[Srs] = None, has_z: Optional[bool] = None, ) -> LineString:
	Rename max_points to max_size in multi_points for clarity. To avoid potential confusion and ensure clarity in the API, consider renaming the max_points parameter in the multi_points function to max_size or max_count. This change would make it clearer that the parameter controls the number of points in the MultiPoint object, not the maximum value of the points themselves. pygeoif/hypothesis/strategies.py [407-414] def multi_points( draw: st.DrawFn, *, - min_points: int = 1, - max_points: Optional[int] = None, + min_size: int = 1, # Renamed for clarity + max_size: Optional[int] = None, # Renamed for clarity srs: Optional[Srs] = None, has_z: Optional[bool] = None, ) -> MultiPoint:
	Add GEOMETRYCOLLECTION to the regular expression to handle all geometry types. The regular expression gcre is updated to include more geometry types but lacks the GEOMETRYCOLLECTION type. Consider adding it to handle all geometry types appropriately. pygeoif/factories.py [58-60] gcre: Pattern[str] = re.compile( - r"POINT|LINESTRING|LINEARRING|POLYGON|MULTIPOINT|MULTILINESTRING|MULTIPOLYGON", + r"POINT|LINESTRING|LINEARRING|POLYGON|MULTIPOINT|MULTILINESTRING|MULTIPOLYGON|GEOMETRYCOLLECTION", )
	Add more specific property tests for line geometries to cover edge cases. The tests for line geometries include several @given decorators from Hypothesis. While these tests are well-structured, consider adding edge case scenarios or more specific property tests to further validate the geometrical operations and properties. For example, testing with extremely large coordinates, lines with zero length, or lines that form specific shapes could uncover edge cases not covered by more general tests. tests/hypothesis/test_line.py [36-37] -@given(line_strings()) -def test_bounds(line: geometry.LineString) -> None: +# Example for an additional test case +@given(line_strings(min_points=2, max_points=2, allow_collinear=True)) +def test_zero_length_line_bounds(line: geometry.LineString) -> None:
	Add a description or example for the Hypothesis strategies. Consider adding a brief description or usage example for the Hypothesis strategies provided for geometries. This will help users understand how they can leverage these strategies for property-based testing in their projects. README.rst [36-37] It provides Hypothesis strategies for all geometries for property based -testing with Hypothesis_. +testing with Hypothesis_. These strategies can be used to generate random geometries for testing purposes, enhancing the robustness of your tests.
	Align the visual style of newly added badges. For the newly added badges, consider aligning their visual style to ensure a consistent and professional look in the README file. README.rst [53-55] -.. image:: https://img.shields.io/badge/property_based_tests-hypothesis-green +.. image:: https://img.shields.io/badge/property_based_tests-hypothesis-green?style=flat-square :target: https://hypothesis.works :alt: Hypothesis
	Add a section on how to contribute to the project. Add a section or a note about how to contribute to the project, including running tests with Hypothesis. This encourages community contributions and helps new contributors get started. README.rst [420] .. _Hypothesis: https://hypothesis.works +Contributing +------------ +We welcome contributions! To get started, please see our contribution guidelines. To run tests locally, you'll need to install Hypothesis. +
Maintainability	Refactor repeated srs checks into a helper function to reduce code duplication. To improve code readability and maintainability, consider refactoring the repeated pattern of checking srs and setting longitudes, latitudes, and elevations in _point_coords_2d and _point_coords_3d functions into a separate helper function. This will reduce code duplication and make the codebase easier to maintain. pygeoif/hypothesis/strategies.py [127-129] -if srs: - longitudes = srs.longitudes() - latitudes = srs.latitudes() +def get_coordinates(srs, dimension='2d'): + if dimension == '2d': + return srs.longitudes(), srs.latitudes() + else: + return srs.longitudes(), srs.latitudes(), srs.elevations()
	Refactor code to avoid direct len usage in conditions for better readability. The convex_hull function uses noqa: PLR2004 to bypass linting rules. Consider refactoring the code to avoid using len in conditions directly, enhancing readability and maintainability. pygeoif/functions.py [124] -if len(points) <= 2: # noqa: PLR2004 +points_count = len(points) +if points_count <= 2:
	Update the from_coordinates method's type hint for clarity and consistency. The method from_coordinates in the LineString class uses a type hint for coordinates that is not consistent with the method's documentation and usage. Update the type hint to match the expected input. pygeoif/geometry.py [407] -def from_coordinates(cls, coordinates: LineType) -> "LineString": +def from_coordinates(cls, coordinates: Sequence[PointType]) -> "LineString":
	Integrate new line and polygon types throughout the codebase. The introduction of Line2D, Line3D, Poly2d, and Poly3d types adds clarity to the type definitions. However, it's important to ensure that these new types are fully integrated and utilized throughout the codebase. This includes updating function signatures, type checks, and documentation to reflect the new, more specific types. This will enhance code readability and maintainability by making the expected data structures clearer. pygeoif/types.py [33-48] -Line2D = Sequence[Point2D] -Line3D = Sequence[Point3D] -LineType = Union[Line2D, Line3D] +# Ensure that functions accepting or returning lines use LineType in their type hints.
Possible issue	Ensure input is sorted for the groupby function in dedupe to work correctly. The dedupe function uses groupby without sorting the input, which may not work as expected for unsorted data. Ensure the input is sorted or revise the approach to handle unsorted data correctly. pygeoif/functions.py [79] -return cast(LineType, tuple(coord for coord, _count in groupby(coords))) +return cast(LineType, tuple(coord for coord, _ in groupby(sorted(coords))))
Bug	Remove or correct the nonsensical assertion in the test. The assertion assert gc1 != gc1 is always false and does not make sense in a test. It looks like a mistake. Review the logic behind this assertion. tests/test_geometrycollection.py [399] -assert gc1 != gc1 # noqa: PLR0124 +# Correct or remove the assertion as appropriate
Best practice	Use consistent data structures for assertions in test cases. Consider using a consistent data structure for assertions in test cases. In the updated code, tuples are used for assertions, whereas the original code used lists. This inconsistency might lead to confusion or errors in future test modifications or when comparing results. It's generally a good practice to stick to one type of data structure for similar operations unless there's a specific reason to do otherwise. tests/test_functions.py [154] -assert hull == ((0, 0), (1, 0), (1, 1), (0, 0)) +assert hull == [(0, 0), (1, 0), (1, 1), (0, 0)]
	Add job dependencies to the GitHub Actions workflow to optimize CI resource usage. The workflow has been split into separate jobs for running tests with and without hypothesis, and for test coverage. This modular approach is good for clarity and specific testing goals. However, consider adding job dependencies using needs to ensure that basic tests pass before running more complex or resource-intensive tests like hypothesis or coverage tests. This can help to quickly identify fundamental issues before using more CI resources. .github/workflows/run-all-tests.yml [29-33] hypothesis-tests: + needs: [cpython, static-tests, pypy] runs-on: ubuntu-latest
Performance	Dynamically adjust Hypothesis max_examples based on the environment to optimize test run times. Registering the 'exhaustive' profile with 10,000 examples for Hypothesis is a good practice for thorough testing. However, running this many examples can be time-consuming, especially in CI environments. Consider dynamically adjusting the max_examples based on the environment (local vs. CI) to balance thoroughness with test run times. For CI, a lower number of examples might be sufficient, while local or pre-release testing could use the exhaustive profile. tests/conftest.py [11] -settings.register_profile("exhaustive", max_examples=10_000) +import os +max_examples = 10_000 if os.getenv('CI') != 'true' else 1000 +settings.register_profile("exhaustive", max_examples=max_examples)

PR Code Suggestions

Category	Suggestions
Maintainability	Use more descriptive variable names for better readability. Consider using a more descriptive variable name instead of coordinate for the partial function that creates a hypothesis strategy for generating float coordinates. A more descriptive name could improve code readability and maintainability. pygeoif/hypothesis/strategies.py [43-48] -coordinate = partial( +float_coordinate_strategy = partial( st.floats, allow_infinity=False, allow_nan=False, allow_subnormal=False, width=32, )
	Refactor geometry generation strategies for better readability. In the geometry_collections function, instead of using st.one_of with a large list of strategies, consider defining a separate strategy that encapsulates this logic. This can improve code readability and make it easier to manage the strategies used for generating different geometry types. pygeoif/hypothesis/strategies.py [578-603] -st.one_of( - points(srs=srs, has_z=has_z), - line_strings(max_points=max_points, srs=srs, has_z=has_z), - linear_rings(max_points=max_points, srs=srs, has_z=has_z), - polygons( - max_points=max_points, - min_interiors=min_interiors, - max_interiors=max_interiors, - srs=srs, - has_z=has_z, - ), - multi_points(max_points=max_points, srs=srs, has_z=has_z), - multi_line_strings( - max_points=max_points, - max_lines=max_geoms, - srs=srs, - has_z=has_z, - ), - multi_polygons( - max_points=max_points, - min_interiors=min_interiors, - max_interiors=max_interiors, - max_polygons=max_geoms, - srs=srs, - has_z=has_z, - ), -) +def geometry_strategy(srs, has_z, max_points, max_geoms, min_interiors, max_interiors): + return st.one_of( + points(srs=srs, has_z=has_z), + line_strings(max_points=max_points, srs=srs, has_z=has_z), + linear_rings(max_points=max_points, srs=srs, has_z=has_z), + polygons( + max_points=max_points, + min_interiors=min_interiors, + max_interiors=max_interiors, + srs=srs, + has_z=has_z, + ), + multi_points(max_points=max_points, srs=srs, has_z=has_z), + multi_line_strings( + max_points=max_points, + max_lines=max_geoms, + srs=srs, + has_z=has_z, + ), + multi_polygons( + max_points=max_points, + min_interiors=min_interiors, + max_interiors=max_interiors, + max_polygons=max_geoms, + srs=srs, + has_z=has_z, + ), + )
	Use consistent data structures for expected values in tests. Consider using a consistent data structure for the expected hull values across all tests for clarity and maintainability. If tuples are preferred for immutability or other reasons, ensure all tests use tuples. If lists are preferred for their mutability or other reasons, ensure all tests use lists. tests/test_functions.py [154] -assert hull == ((0, 0), (1, 0), (1, 1), (0, 0)) +assert hull == [(0, 0), (1, 0), (1, 1), (0, 0)]
	Improve readability by aligning Union types consistently. For better readability and maintainability, consider aligning the Union types in PolygonType similarly to Poly2d and Poly3d. This will make the type definitions more consistent and easier to understand at a glance. pygeoif/types.py [45-48] -PolygonType = Union[ - Poly2d, - Poly3d, -] +PolygonType = Union[Poly2d, Poly3d]
Enhancement	Add validation for min and max XYZ values in the Srs class. For the Srs dataclass, consider adding a method to validate the min_xyz and max_xyz upon initialization to ensure that the minimum values are not greater than the maximum values. This can help prevent logical errors when generating coordinates within these bounds. pygeoif/hypothesis/strategies.py [52-69] @dataclass(frozen=True) class Srs: name: str min_xyz: Tuple[Optional[float], Optional[float], Optional[float]] max_xyz: Tuple[Optional[float], Optional[float], Optional[float]] + def __post_init__(self): + for min_val, max_val in zip(self.min_xyz, self.max_xyz): + if min_val is not None and max_val is not None and min_val > max_val: + raise ValueError("Minimum XYZ values must not exceed the maximum XYZ values.") +
	Improve error messages for better debugging. When raising ValueError in functions like line_strings, linear_rings, and polygons for invalid max_points, consider adding more context to the error message, such as the function name and the received max_points value. This can help in debugging and understanding the source of the error more quickly. pygeoif/hypothesis/strategies.py [281] -raise ValueError("max_points must be greater than 1") +raise ValueError(f"line_strings: max_points must be greater than 1, got {max_points}")
	Improve the efficiency and correctness of duplicate removal in dedupe function. Consider using a more efficient way to remove duplicates from coords in the dedupe function. The current implementation using groupby assumes that the input is sorted and only removes consecutive duplicates. If the input is not sorted, this method will not work as expected. Instead, you can use an ordered dictionary to preserve the order of elements while removing duplicates. pygeoif/functions.py [79] -return cast(LineType, tuple(coord for coord, _count in groupby(coords))) +from collections import OrderedDict +return cast(LineType, tuple(OrderedDict.fromkeys(coords)))
	Add "GEOMETRYCOLLECTION" to the regular expression for parsing WKT strings. The regular expression gcre is updated to include "MULTIPOINT|MULTILINESTRING|MULTIPOLYGON" but is missing "GEOMETRYCOLLECTION" which is also a valid geometry type in WKT. Consider adding "GEOMETRYCOLLECTION" to the regular expression to support parsing WKT strings that represent geometry collections. pygeoif/factories.py [58-60] gcre: Pattern[str] = re.compile( - r"POINT|LINESTRING|LINEARRING|POLYGON|MULTIPOINT|MULTILINESTRING|MULTIPOLYGON", + r"POINT|LINESTRING|LINEARRING|POLYGON|MULTIPOINT|MULTILINESTRING|MULTIPOLYGON|GEOMETRYCOLLECTION", )
	Include Python 3.7 in the testing matrix for broader compatibility testing. To ensure broad compatibility and catch potential issues across different Python versions, consider including Python 3.7 in the testing matrix. This can help identify any version-specific issues early in the development process, especially if the library is intended to support Python 3.7. .github/workflows/run-all-tests.yml [12] -python-version: ['3.8', '3.9', '3.10', '3.11', '3.12', '3.13-dev'] +python-version: ['3.7', '3.8', '3.9', '3.10', '3.11', '3.12', '3.13-dev']
	Add a description or example for the Hypothesis strategies. Consider adding a brief description or usage example for the Hypothesis strategies provided for geometries. This will help users understand how they can leverage these strategies for property-based testing in their projects.

These strategies can be used to generate random geometries for testing purposes, ensuring your code handles a wide range of input scenarios.
	Improve alt texts for badges for better accessibility and SEO. For better accessibility and SEO, consider adding more descriptive alt texts for the newly added badges. This helps users who rely on screen readers and also improves the discoverability of your documentation. README.rst [43-63] -:alt: Documentation -:alt: Hypothesis -:alt: Black -:alt: Mypy +:alt: Documentation for pygeoif on Read the Docs +:alt: Property based testing with Hypothesis for pygeoif +:alt: Code style enforced with Black for pygeoif +:alt: Type checking with Mypy for pygeoif
	Add a table of contents for better navigability. To enhance the documentation's navigability, consider adding a table of contents (TOC) at the beginning. This would help users quickly find the information they're looking for, especially as the documentation grows. README.rst [36-37] +.. contents:: + :local: + :depth: 2 + It provides Hypothesis strategies for all geometries for property based testing with Hypothesis_.
Best practice	Simplify conditional checks for boolean values. Instead of using if has_z is True: and if has_z is False: in the point_coords function, you can simplify the conditionals by directly using if has_z: and elif not has_z:. This makes the code cleaner and more Pythonic. pygeoif/hypothesis/strategies.py [183-186] -if has_z is True: +if has_z: return draw(_point_coords_3d(srs=srs)) -if has_z is False: +elif not has_z: return draw(_point_coords_2d(srs=srs))
	Avoid magic numbers and improve code readability in convex_hull function. In the convex_hull function, the condition if len(points) <= 2 uses a code quality rule suppression comment # noqa: PLR2004. Instead of suppressing the linting rule, consider refactoring the code to avoid using magic numbers directly in the condition. Define a constant with a meaningful name to represent the minimum number of points required to form a polygon. pygeoif/functions.py [124] -if len(points) <= 2: # noqa: PLR2004 +MIN_POINTS_FOR_POLYGON = 3 +if len(points) < MIN_POINTS_FOR_POLYGON:
	Avoid using .example() in tests for deterministic behavior. To avoid potential flakiness in tests due to the stochastic nature of .example(), consider using a more deterministic approach for testing the ValueError exception. Using .example() can lead to non-deterministic behavior and make tests less reliable. tests/hypothesis/test_line.py [17] -line_strings(max_points=1).example() +with pytest.raises(ValueError): + line_strings(max_points=1)
	Enhance test determinism by avoiding .example() for exception testing. Similar to the suggestion for test_line.py, consider removing the use of .example() for testing exceptions in test_max_points_lt_3. This change aims to enhance the determinism and reliability of the test. tests/hypothesis/test_linear_ring.py [15] -linear_rings(max_points=3).example() +with pytest.raises(ValueError): + linear_rings(max_points=3)
	Ensure consistency in badge styles. To maintain consistency in the documentation, consider using the same badge style for all badges. For example, if other badges use a specific color scheme or badge style, ensure the new badges for Hypothesis and Black follow suit. README.rst [53-57] -.. image:: https://img.shields.io/badge/property_based_tests-hypothesis-green -.. image:: https://img.shields.io/badge/code_style-black-000000.svg +.. image:: https://img.shields.io/badge/property_based_tests-hypothesis-<your_color_scheme> +.. image:: https://img.shields.io/badge/code_style-black-<your_color_scheme>.svg
	Verify the validity of newly added external links. Ensure all external links, especially those added recently, are valid and lead to the intended web pages. Broken links can significantly impact user trust and the credibility of the documentation. README.rst [420] -.. _Hypothesis: https://hypothesis.works +.. _Hypothesis: https://hypothesis.works # Ensure this link is valid and accessible
Possible issue	Remove or correct the self-inequality assertion in tests. The assertion assert gc1 != gc1 is likely a mistake, as it checks if an object is not equal to itself, which should always be false. This might have been intended as a test for the equality operator, but as written, it does not serve a useful testing purpose. Consider removing or correcting this line. tests/test_geometrycollection.py [399] -assert gc1 != gc1 # noqa: PLR0124 +# Corrected or removed line
Bug	Ensure consistent tuple structure in Polygon.coords property. In the Polygon class, the coords property uses a cast to PolygonType but does not handle the case where self._geoms[1] is empty, which could lead to a mismatch in the expected tuple structure. It's safer to always return a tuple with two elements, the second being an empty tuple if there are no interiors. pygeoif/geometry.py [580-588] -if self._geoms[1]: - return cast( - PolygonType, - ( - self.exterior.coords, - tuple(interior.coords for interior in self.interiors if interior), - ), - ) -return cast(PolygonType, (self.exterior.coords,)) +return cast( + PolygonType, + ( + self.exterior.coords, + tuple(interior.coords for interior in self.interiors if interior) if self._geoms[1] else (), + ), +)

[sourcery-ai]

suggestion (performance): Consider using a set for deduplication to improve efficiency.

Using a set to remove duplicates before casting back to a tuple might be more efficient than relying on groupby, especially for large datasets.

[sourcery-ai]

issue (bug_risk): Ensure that points are sorted before constructing the hull.

The algorithm assumes that points are pre-sorted. If they're not, the resulting hull might not be correct. Consider adding a sort operation if not already handled.

[sourcery-ai]

suggestion (testing): Consider renaming multi_poly to geom_collection for clarity.

The variable name multi_poly might be misleading in the context of testing GeometryCollection. A name like geom_collection would more accurately reflect the tested type.

[sourcery-ai]

issue (testing): Update the module docstring to reflect the correct test subject.

The current docstring suggests that the module tests MultiPolygons, but it actually tests GeometryCollection. Please update it accordingly.

[sourcery-ai]

suggestion (testing): Add tests for mixed dimensionality within GeometryCollection.

Currently, the tests either use 2D or 3D geometries exclusively. It would be beneficial to add a test case that includes a mix of 2D and 3D geometries within a single GeometryCollection to ensure proper handling of mixed dimensionality.

[sourcery-ai]

suggestion (testing): Verify individual points in MultiPoint after convex hull operation.

While the test checks the bounds of the convex hull against the MultiPoint, it would be more thorough to also verify that each point within the MultiPoint is correctly represented in the convex hull.

[sourcery-ai]

suggestion (testing): Ensure Polygon interiors are preserved after convex hull operation.

The test verifies the bounds of the convex hull, but it should also check that the interiors (holes) of the Polygon are correctly handled or explicitly document the expected behavior if they are not preserved.

[sourcery-ai]

suggestion (testing): Add test for LineString simplification.

In addition to testing the convex hull, consider adding a test case for LineString simplification to ensure that the simplification process retains the essential shape of the LineString.
