pipwrap 0.1.1

Manages pip requirements files for multiple environments, e.g. production and development

pipwrap simplifies handling Python project requirements across multiple environments. pip freeze > requirements.txt gets your project started, but do you really want mock, coverage, etc. installed on your production server? If you’ve ever found yourself sifting through the output of pip freeze trying to figure out what packages you’ve installed but didn’t yet add to one of your requirements files, then pipwrap is the tool for you.

Features

• Inspect a list of packages and create or update requirements files

• Remove stray packages in virtualenv

Installation

You can get pipwrap from PyPI with:

pip install pipwrap

The development version can be installed with:

pip install -e git://github.com/jessamynsmith/pipwrap.git#egg=pipwrap

If you are developing locally, your version can be installed from the working directory with:

python setup.py.install

Usage

Getting Started with pipwrap

1. (Optional) Create requirements files with a list of your packages

2. Interactively populate requirements files from currently installed packages:

   pipwrap -r

3. Create a top-level requirements.txt file that points to your production requirements, e.g. “-r production.txt”

Keeping requirements up to date with pipwrap

1. Interactively update requirements files from currently installed packages:

   pipwrap -r

2. Remove stray packages in virtualenv:

   pipwrap -x

Development

Fork the project on github and git clone your fork, e.g.:

git clone https://github.com/<username>/pipwrap.git

Create a virtualenv and install dependencies:

mkvirtualenv pipwrap
pip install -r requirements/package.txt -r requirements/test.txt

Run tests with coverage (should be 100%) and check code style:

coverage run -m nose
coverage report -m
flake8

Verify all supported Python versions:

pip install tox
tox

Install your local copy:

python setup.py.install
