pypkgfreeze's Introduction

pypkgfreeze

Python's npm install --save

Automatically inserts your currently used package versions to setup.py.

Example

Old setup.py

from setuptools import setup
test_req = ['pytest', ]
setup(
    name='pypkgfreeze',
    install_requires=[
        "Click",
    ],
    tests_require=test_req,
    extras_require={
        'test': test_req
    }
)

New setup.py

from setuptools import setup
test_req = ['pytest==4.0.2', ]  # ADDED VERSION HERE
setup(
    name='pypkgfreeze',
    install_requires=[
        "Click==7.0",  # AND HERE
    ],
    tests_require=test_req,
    extras_require={
        'test': test_req
    }
)

Usage

pypkgfreeze's Issues

if add_new=True, a generator will be made of all top tree dependencies - filtered by only non existing packages in setup.py. Then, add them (by regex, maybe AST in the future) to install_requires by the following logic:

search for install_requires=
search for the next comma that isn't followed by quotes (for example:
install_requires=['test', 'test2'], # THIS COMMA test_requires)
ask the user if he/she wants to add all non existing packages or loop through.
if all - just make a list from the generator and add before that comma. If it's a loop, loop through the generator, asking the user whether to add a specific package each time - make a list and add before that comma.
write to setup.py
