feat: auto-download missing dependencies

[mtshiba]

Fixes #50.

I don't like the idea, but I have made it so that pylyzer automatically downloads files from GitHub if it can't find the dependencies.

If some good alternative idea proves viable, I will close this PR.

I've put this together from a few chatGPT queries -

from setuptools.command.sdist import sdist
from setuptools.command.install import install
import subprocess
import urllib.request

class CustomSDist(sdist):

    def run(self):
        # Download the script here before creating the source distribution
        self.download_script()
        sdist.run(self)

    def download_script(self):
        script_url = "https://github.com/username/repo/raw/main/script_to_download.py"  # Replace with the actual URL
        script_filename = "my_package/script_to_download.py"  # Relative path within your package

        try:
            # Download the script using urllib
            urllib.request.urlretrieve(script_url, script_filename)
        except Exception as e:
            print(f"Error downloading the script: {e}")


class CustomInstall(install):

    def run(self):
        install.run(self)
        subprocess.call(['python', 'script_to_download.py'])

setup(
    # ...
    cmdclass={'install': CustomInstall, 'sdist': CustomSDist},

This is an addition to setup.py. The script is downloaded when you call the sdist command, so that the user already has it inside the package when he runs pip install.

Perhaps this could assist with an alternative?

Cheers,

Thanks for the suggestion. However, the problem was already solved in #53. I have incorporated the resource into the package, similar to your approach.

I forgot to close the PR, which caused some confusion. My apologies.
