Decorator resolves as wron file path

[aaltat]

Reported in MarketSquare/robotframework-browser#2382

Original issue says
Describe the bug

In the documentation generated with libdoc (in JSON or libspec format), the source file for the keyword New Context is Browser/utils/deprecated.py.

To Reproduce
Steps to reproduce the behavior:

Execute libdoc Browser browser.json
Search for "name": "New Context" and then for "source":
Expected behavior

The source of the keyword New Context is

OS: Windows 10

The keyword New Context has the following definition

@keyword(tags=("Setter", "BrowserControl"))
@attribute_warning(
    old_args=("videosPath", "videoSize"), new_args=("recordVideo", "recordVideo")
)
def new_context(
    self,
    ...
)

Apparently, libdoc expects that the line after the keyword decorator is a function definition.

Line 142 in ef35336

return os.path.normpath(inspect.getfile(method))

should be:

return os.path.normpath(inspect.getsourcefile(inspect.unwrap(method)))

it is the same like robotframework gets the source for a keyword.

Most likely that is the problem, do you want to do PR, with test, to fix it?

[d-biehl]

sorry for my late answer ;-)

yes I can provide a PR, but only at the end of the week, if it's ok for you. Just have a few days vacation ;-)

No rush take your time.
