decorators#

Decorators for FURY tests.

SKIP_RE

Compiled regular expression object.

doctest_skip_parser(func)

Decorator replaces custom skip test markup in doctests.

warn_on_args_to_kwargs([from_version, ...])

Decorator to enforce keyword-only arguments.

SKIP_RE#

fury.decorators.SKIP_RE()#

Compiled regular expression object.

doctest_skip_parser#

fury.decorators.doctest_skip_parser(func)[source]#

Decorator replaces custom skip test markup in doctests.

Say a function has a docstring:

something # skip if not HAVE_AMODULE
something + else
something # skip if HAVE_BMODULE

This decorator will evaluate the expression after skip if. If this evaluates to True, then the comment is replaced by # doctest: +SKIP. If False, then the comment is just removed. The expression is evaluated in the globals scope of func. For example, if the module global HAVE_AMODULE is False, and module global HAVE_BMODULE is False, the returned function will have docstring:

something # doctest: +SKIP
something + else
something

warn_on_args_to_kwargs#

fury.decorators.warn_on_args_to_kwargs(from_version='0.11.0', until_version='0.14.0')[source]#

Decorator to enforce keyword-only arguments.

This decorator enforces that all arguments after the first one are keyword-only arguments. It also checks that all keyword arguments are expected by the function.

Parameters:

  • from_version (str, optional) – The version of fury from which the function was supported.

  • until_version (str, optional) – The version of fury until which the function was supported.

Returns:

decorator – Decorator function.

Return type:

Callable
