does pants run support periods (‘.’) in folders? If i have src/foo/bar.py with a python_source target in src/foo/BUILD, things work of course but if I change foo to ‘foo.d’, i get

ImportError: Error while finding module specification for 'foo.d.bar' (ModuleNotFoundError: No module named 'foo')

full traceback here

Copy code

The above exception was the direct cause of the following exception:

    raise error(msg.format(mod_name, type(ex).__name__, ex)) from ex
ImportError: Error while finding module specification for 'foo.d.bar' (ModuleNotFoundError: No module named 'foo')

wondering if there is a workaround?

I mean, Python does not support that!:

Copy code

$ mkdir spam.eggs
$ touch spam.eggs/oh_my.py
$ python -c 'from spam.eggs import oh_my'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'spam'

So clearly Pants can't either.

I mean... python doesn't really support that as a module name (it kinda does, in the since that you could override an import hook to support it, but it doesn't work out of the box, and you would need to use

importlib

to get at it since the syntax doesn't support it). You probably want to set up

src/foo.d

as a source root https://www.pantsbuild.org/docs/source-roots
