Dep-Logic is a Python library that provides a robust API for working with package version specifiers and dependencies, supporting logical operations (AND, OR) on them. It is currently at version 0.5.2 and sees active development with several releases per year.

Specifier

✓ from dep_logic import Specifier

✗ from dep_logic import Specifier

This quickstart demonstrates how to create `Specifier` and `SpecifierSet` objects, perform logical AND/OR operations on them, check version containment, and define a `Dependency` object.

from dep_logic import Specifier, SpecifierSet, Dependency # Define specifiers spec1 = Specifier(">=1.0.0,<2.0.0") spec2 = Specifier("~=1.5.0") # equivalent to >=1.5.0,==1.*,==1.5.*, <1.6.0 for a minor release # Perform logical operations combined_spec_and = spec1 & spec2 # Intersection combined_spec_or = spec1 | spec2 # Union print(f"Specifier 1: {spec1}") print(f"Specifier 2: {spec2}") print(f"Intersection (AND): {combined_spec_and}") print(f"Union (OR): {combined_spec_or}") # Check if a version satisfies a specifier assert combined_spec_and.contains("1.5.2") assert not combined_spec_and.contains("1.0.0") # Define a dependency my_dependency = Dependency("my_package", Specifier(">=1.0.0,<2.0.0")) print(f"Dependency: {my_dependency}")

Debug

Known issues

breakingThe `Specifier` and `SpecifierSet` classes are no longer directly importable from the top-level `dep_logic` package. The previously suggested import path `from dep_logic import Specifier` (intended for versions >=0.3.0) is no longer valid, indicating a further change or reversion.

fix

Consult the library's documentation or source code to find the current import path for `Specifier` and `SpecifierSet`, as they are not available directly under `dep_logic`.

affects: >0.3.0

breakingThe `Dependency` API was significantly reworked. The `DependencySpecifier` class was removed, and `Dependency` now takes a `name` and `specifier` directly upon initialization.

fix

Refactor code using `DependencySpecifier` or old `Dependency` constructors to use the new `Dependency(name, specifier)` signature.

affects: <0.4.0

breakingThe `specifier` attribute of `Dependency` objects became non-optional.

fix

Ensure that when creating `Dependency` objects, you always provide a `specifier` argument.

affects: <0.5.0

gotchaBe aware of the difference between `&` (intersection/AND) and `|` (union/OR) for specifiers. Intersection requires a version to satisfy ALL combined conditions, while union requires it to satisfy ANY.

fix

Carefully consider the logical operation needed for your dependency constraints. Test with edge cases to ensure the combined specifier behaves as expected.

affects: All versions
