Relative import still doesn't work?

[nelsyeung]

Reproduction

mkdir -p foo/src
cd foo
touch src/__init__.py

Create the following files:
src/server.py:

from .foo import getab

src/foo.py:

def getab():
    return ''

Run:

stickytape src/server.py --add-python-path . --output-file tmp.py
Traceback (most recent call last):

I don't think this works as an ordinary Python script:

$ python src/server.py 
Traceback (most recent call last):
  File "src/server.py", line 1, in <module>
    from .foo import getab
ImportError: attempted relative import with no known parent package

Ah I see, if I just add an ordinary executable script that imports src.server, it'd work. However, is it not possible to make my example work?

[mwilliamson]

As in make stickytape make the example work, even though the example doesn't work when running it as an ordinary Python script? It might be possible, but I think that stickytape should stick to normal Python behaviour where possible.

Sorry, I mean make stickytape combine scripts that can be imported instead of being executed, but I guess that's beyond the scope of this tool. Thanks
