pipfreeze 2.0.1

Tool to produce better formatted pip freeze.

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.

Motivation

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

astroid==2.4.2
certifi==2020.12.5
chardet==4.0.0
idna==2.10
isort==5.5.3
lazy-object-proxy==1.4.3
mccabe==0.6.1
pylint==2.6.0
requests==2.25.1
six==1.15.0
toml==0.10.1
urllib3==1.26.3
wrapt==1.12.1

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