Pip Freeze

Tool to produce better formatted pip freeze.

Instead of a flat list of requirements, this indents requirements which are dependencies and those that are primary installs. Dependencies shared by multiple packages are commented out.

This format can be re-read by the typical pip install -r requirements.txt and requires not adjustment to other code.

Installation

pip install pipfreeze

Basic Usage

pipfreeze > requirements.txt

Motivation

Typical pip freeze flattens all requirements, regardless of the dependency structure.

cycler==0.10.0
kiwisolver==1.3.1
matplotlib==3.3.4
numpy==1.20.1
pandas==1.2.2
Pillow==8.1.0
pyparsing==2.4.7
python-dateutil==2.8.1
pytz==2021.1
six==1.15.0

This pipfreeze command produces output that is valid requirements.txt but is nested

matplotlib==3.3.4
    cycler==0.10.0
        six==1.15.0
    kiwisolver==1.3.1
    numpy==1.20.1
    Pillow==8.1.0
    pyparsing==2.4.7
    python-dateutil==2.8.1
        # six==1.15.0
pandas==1.2.2
    # numpy==1.20.1
    # python-dateutil==2.8.1
        # six==1.15.0
    pytz==2021.1
