using easy_install (via Distribute or setuptools)
===================================================

It is recommended to use `Distribute for installation`_ as a drop-in
replacement for setuptools_. While setuptools should work well on
Python2 versions, `Distribute`_ allows to install py.test on Python3 
and it avoids issue on Windows.  With either packaging system 
you can type::

    easy_install -U py 

to get the latest release of the py lib and py.test.  The ``-U`` switch
will trigger an upgrade if you already have an older version installed. 
On Linux systems you may need to execute the command as superuser and
on Windows you might need to write down the full path to ``easy_install``. 

The py lib and its tools are expected to work well on Linux,
Windows and OSX, Python versions 2.4, 2.5, 2.6 through to
the Python3 versions 3.0 and 3.1 and Jython

Working from version control or a tarball 
=================================================

To follow development or help with fixing things
for the next release, checkout the complete code
and documentation source with mercurial_::

    hg clone https://bitbucket.org/hpk42/py-trunk/

Development usually takes place on the 'trunk' branch.

.. There also is a readonly subversion
   checkout available which contains the latest release::
   svn co https://codespeak.net/svn/py/dist

You can also go to the python package index and
download and unpack a TAR file::

    http://pypi.python.org/pypi/py/


activating a checkout with setuptools 
--------------------------------------------

With a working `Distribute`_ or setuptools_ installation you can type::

    python setup.py develop 

in order to work inline with the tools and the lib of your checkout.

.. _`directly use a checkout`: 

directly use a checkout or tarball
-------------------------------------------------------------

Once you got yourself a checkout_ or tarball_ you only need to 
set ``PYTHONPATH`` and ``PATH`` environment variables. 
It is usually a good idea to add the parent directory of the ``py`` package 
directory to your ``PYTHONPATH`` and ``py/bin`` or ``py\bin\win32`` to your 
system wide ``PATH`` settings.  There are helper scripts that set ``PYTHONPATH`` and ``PATH`` on your system: 

on windows execute::

    # inside autoexec.bat or shell startup
    c:\\path\to\checkout\bin\env.cmd

on linux/OSX add this to your shell initialization:: 

    # inside .bashrc 
    eval `python ~/path/to/checkout/bin/env.py` 

both of which which will get you good settings 
for ``PYTHONPATH`` and ``PATH``.


note: scripts look for "nearby" py-lib 
-----------------------------------------------------

Note that all `command line scripts`_ will look 
for "nearby" py libs, so if you have a layout like this::

    mypkg/
        subpkg1/
            tests/
        tests/
    py/ 

issuing ``py.test subpkg1`` will use the py lib
from that projects root directory.

Debian and RPM packages 
===================================

As of August 2009 pytest/pylib 1.0 RPMs and Debian packages 
are not available.  You will only find 0.9 versions - 
on Debian systems look for ``python-codespeak-lib``
and Dwayne Bailey has put together a Fedora `RPM`_.
