easypipinstall 0.1.6

easypipinstall installs Python packages similarly to NPM in NodeJS. It automatically maintains the `requirements.txt`, `prod-requirements.txt` and `setup.cfg` files. It also easily uninstalls all the dependencies from those files.

EASY PIP INSTALL

easypipinstall installs Python packages similarly to NPM in NodeJS. It automatically maintains the requirements.txt, prod-requirements.txt and setup.cfg files. It also easily uninstalls all the dependencies from those files. It uses an opinionated pattern where:

• Only two types of dependencies exist: prod and dev.
• All dependencies are listed under requirements.txt.
• By default, dependencies are listed in both requirements.txt and prod-requirements.txt.
• Dependencies are not listed under prod-requirements.txt when the -D option (development mode) is used.
• The setup.cfg file is updated as follows:
  • By default, the dependency is listed without its version under the install_requires property of the [options] section.
  • When the -D option is used, the dependency is listed without its version under the dev property of the [options.extras_require] section.

To install:

pip install easypipinstall

This will add two new CLI utilities: easyi (install) and easyu (uninstall).

Examples:

easyi numpy

This installs numpy (via pip install) then automatically updates the following files:

• setup.cfg (WARNING: this file must already exists):

   [options]
   install_requires = 
   	numpy
  

• requirements.txt and prod-requirements.txt

easyi flake8 black -D

This installs flake8 and black (via pip install) and then automatically updates the following files:

• setup.cfg (WARNING: this file must already exist):

   [options.extras_require]
   dev = 
   	black
   	flake8
  

• requirements.txt only, as those dependencies are installed for development purposes only.

easyu flake8

This uninstalls flake8 as well as all its dependencies. Those dependencies are uninstalled only if other project dependencies do not use them. The setup.cfg and requirements.txt are automatically updated.
