"""Deprecation tooling for Python functions and classes. This package provides a simple decorator-based approach to deprecate functions, methods, and classes while automatically forwarding calls to their replacements. Main Features: - Automatic call forwarding to new implementations - Argument mapping and renaming between old and new APIs - Customizable warning messages and output streams - Per-function and per-argument warning tracking to prevent log spam - Support for multiple deprecation levels via decorator stacking - Audit tools for CI pipelines: wrapper validation, expiry enforcement, chain detection - Testing utilities for writing deterministic tests Core Components: **Main Decorator** (:mod:`deprecate.deprecation`): - :func:`~deprecate.deprecation.deprecated`: Decorator for marking functions/methods as deprecated - :func:`~deprecate.utils.void`: Silences IDE and mypy warnings about unused parameters in deprecated stubs **Audit** (:mod:`deprecate.audit`): - :func:`~deprecate.audit.validate_deprecation_wrapper`: Validate a single wrapper's configuration - :func:`~deprecate.audit.find_deprecation_wrappers`: Scan a package for all deprecated wrappers - :func:`~deprecate.audit.generate_deprecation_table`: Build compact or matrix markdown deprecation tables - :func:`~deprecate.audit.validate_deprecation_expiry`: Detect wrappers that outlived their ``remove_in`` deadline - :func:`~deprecate.audit.validate_deprecation_chains`: Detect deprecated wrappers chaining to other deprecated wrappers - :class:`~deprecate.audit.DeprecationWrapperInfo`: Structured result returned by the audit functions - :class:`~deprecate.audit.ChainType`: Enum describing the kind of deprecation chain detected **Proxy** (:mod:`deprecate.proxy`): - :func:`~deprecate.proxy.deprecated_instance`: Wrap any object with deprecation warnings - :func:`~deprecate.proxy.deprecated_class`: Decorator for deprecating Enum/dataclass definitions **Testing** (:mod:`deprecate.utils`): - :func:`~deprecate.utils.assert_no_warnings`: Context manager asserting that no warnings are raised Quick Example: >>> from deprecate import deprecated >>> >>> def new_function(x: int) -> int: ... '''New implementation.''' ... return x * 2 >>> >>> @deprecated(target=new_function, deprecated_in="1.0", remove_in="2.0") ... def old_function(x: int) -> int: ... '''Old implementation - calls forwarded automatically.''' ... pass >>> >>> result = old_function(5) # Shows warning, returns 10 >>> print(result) 10 Complete Documentation: For detailed examples and use cases, see: https://borda.github.io/pyDeprecate Topics covered: - Simple function forwarding - Advanced argument mapping - Warning-only deprecation (``TargetMode.NOTIFY``) - Self-deprecation (``TargetMode.ARGS_REMAP``) - Multiple deprecation levels - Conditional skip (skip_if parameter) - Class deprecation - Automatic docstring updates - Auditing: wrapper configuration, expiry enforcement, chain detection - Testing deprecated code """ from deprecate.__about__ import * # noqa: F403 from deprecate._types import TargetMode from deprecate.audit import ( ChainType, DeprecatedCallableInfo, # noqa: F401 # backward-compat alias for DeprecationWrapperInfo DeprecationStatus, DeprecationWrapperInfo, TableStyle, find_deprecated_callables, # noqa: F401 # deprecated since 0.6, use find_deprecation_wrappers find_deprecation_wrappers, generate_deprecation_table, validate_deprecated_callable, # noqa: F401 # deprecated since 0.6, use validate_deprecation_wrapper validate_deprecation_chains, validate_deprecation_expiry, validate_deprecation_wrapper, validate_mapping_compatibility, ) # Opt-in strict ``property`` replacement: ``from deprecate import property`` shadows the builtin # in the importing module only, rejecting inner-order ``@property @deprecated`` at class-body time. from deprecate.deprecation import ( _StrictProperty as property, # noqa: F401 # intentional: explicit-import only; excluded from __all__ to prevent star-import from silently enabling strict mode ) from deprecate.deprecation import deprecated from deprecate.proxy import deprecated_class, deprecated_instance from deprecate.utils import ( assert_no_warnings, no_warning_call, # noqa: F401 # deprecated since 0.6, use assert_no_warnings void, ) __all__ = [ "ChainType", "DeprecationStatus", "DeprecationWrapperInfo", "TableStyle", "TargetMode", "assert_no_warnings", "deprecated", "deprecated_class", "deprecated_instance", "find_deprecation_wrappers", "generate_deprecation_table", "validate_deprecation_chains", "validate_deprecation_expiry", "validate_deprecation_wrapper", "validate_mapping_compatibility", "void", ]
