library10.8.4pypypi✓ verified 80d ago

Core library for mathematical object infrastructure in the passagemath ecosystem. Provides base classes for Sage-like elements, parents, categories, coercion framework, and metaclasses. Part of the passagemath distribution (successor to SageMath components). Current version 10.8.4, supports Python 3.11-3.14. Released as part of passagemath v10.8.x series.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Parent

✓ from sage.structure.parent import Parent

✗ from passagemath.objects.parent import Parent

Category

✓ from sage.categories.category import Category

✗ from passagemath.objects.category import Category

Morphism

✓ from sage.categories.morphism import Morphism

✗ from passagemath.objects.morphism import Morphism

Create a custom parent class with category support using passagemath-objects.

from passagemath.objects.parent import Parent from passagemath.objects.element import Element from passagemath.objects.category import Category class MyParent(Parent): def __init__(self): super().__init__(category=Category()) p = MyParent() print(isinstance(p, Parent)) # True

Debug

Known issues

breakingAll import paths changed from sage.* to passagemath.*. Code written for SageMath will not work.

fix

Replace sage structure imports with passagemath.objects.*

affects: >=10.0

deprecatedThe class `CategoryInfinite` is deprecated; use `Category` with appropriate finiteness parameter.

fix

Replace `CategoryInfinite()` with `Category(is_finite=False)`

affects: 10.8.0-10.8.4

gotchaCoercion model initialization requires explicit setup; default model raises ValueError if used directly without configuration.

fix

Call `CoercionModel()._init_coercion()` after creation or use `from passagemath.objects.parent import Parent` which sets it up automatically.

affects: >=10.0

gotchaMemory leaks may occur if elements are not properly garbage collected due to reference cycles in coercion caches.

fix

Use `gc.collect()` after cycles or call `Element._reset_cache()` periodically.

affects: all
