A probable bug with zip imports

[hukkin]

I haven't confirmed, but seems like there might be an issue with zip imports here:

em-keyboard/src/em/cli.py

Lines 13 to 16 in 75a819a

	with as_file(files("em").joinpath("emojis.json")) as em_json:
	EMOJI_PATH = em_json
	CUSTOM_EMOJI_PATH = os.path.join(os.path.expanduser("~/.emojis.json"))

The as_file context manager, when exiting, according to the docs

cleans up any temporary file or directory created when the resource was extracted from e.g. a zip file.

So importlib.resources reads the file from the .zip, creates a temporary file, and deletes it when exiting, after which it can no longer be read.

I think best would be to call read_text or open on the importlib.resources.abc.Traversable and never make a pathlib.Path out of it.

I confirmed this is an issue, by importing and running the package as shown here https://docs.python.org/3/library/zipimport.html#examples

Please can you give concrete steps to reproduce, including how to create the zip to begin with?

[hukkin]

Yes, of course. One easy way to reproduce this is to use a regular .whl as the zip file and add that to PYTHONPATH:

pipx run build
PYTHONPATH=dist/em_keyboard-5.0.1.dev3-py3-none-any.whl python3.13 -m em grinning_face

This will currently error in main branch with

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp5yun71gaemojis.json'
