Using pyinstaller with setuptools package

[Vishesh Mangla]

How to write the spec file? I just learned setuptools , made this first package and now I need to build an exe for windows.

I 'm on a win 10, using python=3.8.0 and using PiPy 's latest version of pyinstaller.

```b.spec

def Entrypoint(dist, group, name, **kwargs):
    import pkg_resources

    # get toplevel packages of distribution from metadata
    def get_toplevel(dist):
        distribution = pkg_resources.get_distribution(dist)
        if distribution.has_metadata('top_level.txt'):
            return list(distribution.get_metadata('top_level.txt').split())
        else:
            return []

    kwargs.setdefault('hiddenimports', [])
    packages = []
    for distribution in kwargs['hiddenimports']:
        packages += get_toplevel(distribution)

    kwargs.setdefault('pathex', [])
    # get the entry point
    ep = pkg_resources.get_entry_info(dist, group, name)
    # insert path of the egg at the verify front of the search path
    kwargs['pathex'] = [ep.dist.location] + kwargs['pathex']
    # script name must not be a valid module name to avoid name clashes on import
    script_path = os.path.join(workpath, name + '-script.py')
    print("creating script for entry point", dist, group, name)
    with open(script_path, 'w') as fh:
        print("import", ep.module_name, file=fh)
        print("%s.%s()" % (ep.module_name, '.'.join(ep.attrs)), file=fh)
        for package in packages:
            print("import", package, file=fh)

    return Analysis(
        [script_path] + kwargs.get('scripts', []),
        **kwargs
    )

Entrypoint('mailerkivy', 'gui_scripts', 'mailer.main')

```

```setup.py

import setuptools

setuptools.setup(

    name="mailerkivy",

    version="0.1.1",

  

    python_requires='>=3.7',

    packages=setuptools.find_packages("src"),

    package_dir={"": "src"},

    entry_points={

        "gui_scripts": [

            "mailer = mailer.main:main",

        ],

    },

        setup_requires="setuptools",

    install_requires=[

        "kivy>=2.0.0",

        "beautifulsoup4>=4.9.3",

        "docxtpl>=0.11.3",

        "pywin32>=300",

        "plyer>=2.0.0"

        

    ],

   extras_require={

        "build_for_windows":  ["pyinstaller>=4.2", "pyinstaller"],

    }

)

```
