sigtools

sigtools: utilities to manipulate callable objects' signatures

The sigtools python library provides:

• sigtools.signature to resolve function signatures, taking into account parameters added or removed by decorators.
• Decorators to specify keyword-only parameters, annotations and positional-only parameters, even on python2: sigtools.modifiers
• Decorators to specify how *args, **kwargs are handled, in a way that can be introspected: sigtools.specifiers
• Function combination routines that preserve signatures: sigtools.wrappers
• Functions to manipulate signature objects likewise: sigtools.signatures
