pip-tools = pip-compile + pip-sync
==================================
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?`_

Installation
============
.. code-block::
$ pip install --upgrade pip # pip-tools needs pip==8.0 or higher (!)
$ pip install pip-tools
Example usage for ``pip-compile``
=================================
Requirements from setup.py
--------------------------
Suppose you have a Flask project, and want to pin it for production.
If you have a ``setup.py`` with ``install_requires=['Flask']``, then run
``pip-compile`` without any arguments:
.. code-block::
$ pip-compile
#
# This file is autogenerated by pip-compile
# To update, run:
#
# pip-compile --output-file requirements.txt setup.py
#
click==6.7 # via flask
flask==0.12.2
itsdangerous==0.24 # via flask
jinja2==2.9.6 # via flask
markupsafe==1.0 # via jinja2
werkzeug==0.12.2 # via flask
``pip-compile`` will produce your ``requirements.txt``, with all the Flask
dependencies (and all underlying dependencies) pinned. You should put your
requirements file under version control.
Without setup.py
----------------
If you don't use ``setup.py`` (`it's easy to write one`_), you can instead
write the following line to a file:
.. code-block::
# requirements.in
Flask
This time, run ``pip-compile requirements.in``:
.. code-block::
$ pip-compile requirements.in
#
# This file is autogenerated by pip-compile
# To update, run:
#
# pip-compile --output-file requirements.txt requirements.in
#
click==6.7 # via flask
flask==0.12.2
itsdangerous==0.24 # via flask
jinja2==2.9.6 # via flask
markupsafe==1.0 # via jinja2
werkzeug==0.12.2 # via flask
And it will produce your ``requirements.txt``, with all the Flask dependencies
(and all underlying dependencies) pinned. Don't forget to put this file under
version control as well.

Using hashes
------------
If you would like to use *Hash-Checking Mode* available in *pip* since version
8.0, ``pip-compile`` offers ``--generate-hashes`` flag:
.. code-block::
$ pip-compile --generate-hashes requirements.in
#
# This file is autogenerated by pip-compile
# To update, run:
#
# pip-compile --generate-hashes --output-file requirements.txt requirements.in
#

# via flask
Updating requirements
---------------------
To update all packages, periodically re-run ``pip-compile --upgrade``.
To update a specific package to the latest or a specific version use the
``--upgrade-package`` or ``-P`` flag:
.. code-block::
$ pip-compile --upgrade-package flask # only update the flask package
$ pip-compile --upgrade-package flask --upgrade-package requests # update both the flask and requests packages
$ pip-compile -P flask -P requests==2.0.0 # update the flask package to the latest, and requests to v2.0.0
If you use multiple Python versions, you can run ``pip-compile`` as
``py -X.Y -m piptools compile ...`` on Windows and
``pythonX.Y -m piptools compile ...`` on other systems.
Configuration
-------------
You might be wrapping the pip-compile command in another script. To avoid
confusing consumers of your custom script you can override the update command
generated at the top of requirements files by setting the
``CUSTOM_COMPILE_COMMAND`` environment variable.
.. code-block::
$ CUSTOM_COMPILE_COMMAND="./pipcompilewrapper" pip-compile requirements.in
#
# This file is autogenerated by pip-compile
# To update, run:
#
# ./pipcompilewrapper
#
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
Example usage for `pip-sync`
============================
Now that you have a ``requirements.txt``, you can use ``pip-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-block::
$ pip-sync

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.
.. code-block::
$ pip-sync dev-requirements.txt requirements.txt
Passing in empty arguments would cause it to default to ``requirements.txt``.
If you use multiple Python versions, you can run ``pip-sync`` as
``py -X.Y -m piptools sync ...`` on Windows and
``pythonX.Y -m piptools sync ...`` on other systems.
