Verified usage

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

undecorated

✓ from undecorated import undecorated

✗ from undecorated import undecorate

Basic usage: undecorate a decorated function to get the original.

from undecorated import undecorate def decorator(func): def wrapper(*args, **kwargs): return func(*args, **kwargs) return wrapper @decorator def foo(): return 'foo' print(foo()) # calls wrapper print(undecorate(foo)) # returns original function print(undecorate(foo)()) # 'foo'

Debug

Known issues

gotchaundecorate() works by inspecting closure cells, which may fail for complex decorators (e.g., functools.lru_cache, class-based decorators, or decorators that return a different type).

fix

Check the result; if the original function isn't found, consider alternative approaches like storing the original manually.

affects: >=0.1.0

gotchaApplying undecorate to an already undecorated function returns the same function; it does not error. This can mask misuses.

fix

Verify the function is actually decorated before undecorating to avoid logic errors.

affects: >=0.1.0

gotchaDoes not support Python 3.12+ if decorators use new closure behavior or PEP 695 (type parameter syntax) changes. The package has not been updated for recent CPython internals.

fix

Test on your Python version; if it fails, consider forking or using an alternative library.

affects: >=0.3.0
