create a gistlib executable file in python

To create an executable file for your Python code in a convenient and portable way, you can use a tool called setuptools which provides a console_scripts entry point.

First, install setuptools if it is not already installed:

$ pip install setuptools

2 lines

Next, create a setup.py file in your project folder with the following contents:

main.py
from setuptools import setup, find_packages

setup(
    name='gistlib',
    version='0.1',
    packages=find_packages(),
    entry_points={
        'console_scripts': [
            'gistlib=gistlib.main:main',
        ],
    },
)
230 chars
13 lines

This specifies the project name and version, the packages to include (using find_packages()), and the entry point for the console script. In this example, the console script is called gistlib and it calls the main() function in the main module of the gistlib package.

You can adjust the entry point to match your project's structure and naming.

Finally, run the following command to create the executable file:

$ python setup.py install

This will create a gistlib executable file in your system's PATH, which can be called from any directory in your terminal or command prompt.
