Pip Requ
========
A set of command line tools to help you keep your pip-based packages
fresh, even when you've pinned them. `You do pin them, right?`__
__ http://nvie.com/posts/pin-your-packages
Pip Requ is a fork of pip-tools_ by Vincent Driessen.
.. _pip-tools: https://github.com/nvie/pip-tools
Installation
------------
.. code::
$ pip install --upgrade pip # Pip Requ needs pip==8.0 or higher
$ pip install pip-requ
Example usage for ``pip-requ compile``
--------------------------------------
Suppose you have a Flask project, and want to pin it for production.
Write the following line to a file:
.. code::
# requirements.in
Flask
Now, run ``pip-requ compile requirements.in``:
.. code::
$ pip-requ compile requirements.in
#
# This file is autogenerated by pip-requ compile
# Make changes in requirements.in, then run this to update:
#
# pip-requ compile requirements.in
#
flask==0.10.1
itsdangerous==0.24 # via flask
jinja2==2.7.3 # via flask
markupsafe==0.23 # via jinja2
werkzeug==0.10.4 # via flask
And it will produce your ``requirements.txt``, with all the Flask
dependencies (and all underlying dependencies) pinned. Put this file
under version control as well.
To update all packages, periodically re-run ``pip-requ compile
--upgrade``.
To update a specific package to the latest or a specific version use the
``--upgrade-package`` or ``-P`` flag:
.. code::
pip-requ compile --upgrade-package flask
# only update the flask package
pip-requ compile --upgrade-package flask --upgrade-package requests
# update both the flask and requests packages
pip-requ compile -P flask -P requests==2.0.0
# update the flask package to the latest, and requests to v2.0.0
Example usage for ``pip-requ sync``
-----------------------------------
Now that you have a ``requirements.txt``, you can use ``pip-requ sync``
to update your virtual env to reflect exactly what's in there. Note:
this will install/upgrade/uninstall everything necessary to match the
``requirements.txt`` contents.
.. code::
$ pip-requ sync
Uninstalling flake8-2.4.1:

Found existing installation: click 4.0
Uninstalling click-4.0:
Successfully uninstalled click-4.0
Successfully installed click-4.1
To sync multiple ``*.txt`` dependency lists, just pass them in via command
line arguments e.g.::
$ pip-requ sync dev-requirements.txt requirements.txt
Passing in empty arguments would cause it to default to
``requirements.txt``.
