pipw 1.0.5

A wrapper for pip to save packages in requirements files similar to npm.
There are better alternatives to pip (like Pipenv), but this was created for
those who want or need to continue using pip. For example, those who
collaborate in projects that use pip requirements files.

Installing
$ pip install pipw

Usage
pipw (install|uninstall) [-e] <package>... [options]
Options:
-s, --save Save packages to the requirements file. This is default
unless --no-save. Packages are saved in
requirements.txt unless a custom configuration is used.
-n, --no-save Prevent save packages to the requirements file.
--config <path> Pass a custom config file. By default it looks for a
.pipwrc file in the directory where the command is
executed, or in the user's home directory.
-m, --env <name> Save in a environment previously declared in the config
file.
--save-to <path> Save to a custom file.
--no-detect-version Do not detect installed version, and save package
version only if the version is passed.
--help Show this message and exit.
All pip commands and options are still available.

Config file
You can create a .pipwrc file to use a custom configuration. By default
it looks for the file in the directory where the command is executed, or in the
user’s home directory. You can also pass a custom file to the --config
option.
Example of a config file:
requirements: requirements.txt
specifier: ~=
detect_version: true
envs:
dev: requirements/dev.txt

Environments
As you can see, you can set environment files in the configuration file:
requirements: requirements/prod.txt
envs:
dev: requirements/dev.txt
test: requirements/test.txt
Use the -m (or –env) option to save the packages in an environment file:
$ pipw install pytest -m test
If no environment is passed, the value defined in requirements are used by
default. If this value is not defined, a requirements.txt file is used by
default. These files are created automatically if they do not exist.
The uninstall command will remove the package in all files, unless the -m
option is passed.

Tests
Tests are in tests/. To run the tests use one of these commands:
$ make tests
$ make wip-tests
$ make review-tests
You can also pass the environment. For example:
$ make tests env=py35
