Installing a development environement on Windows
================================================
Setting up a Windows development environment is not too complicated
but it requires a series of small steps.
We proposed an example of a typical |cubicweb| installation on Windows
from sources. We assume everything goes into ``C:\\`` and for any
package, without version specification, "the latest is
the greatest".
Take into the mind that adjusting the installation drive should be
straightforward.
Install the required elements
-----------------------------
|cubicweb| requires some base elements that must be installed to run
correctly. So, first of all, you must install them :
* python >= 2.5 and < 3
(`Download Python <http://www.python.org/download/>`_).
You can also consider the Python(x,y) distribution
(`Download Python(x,y) <http://code.google.com/p/pythonxy/wiki/Downloads>`_)
as it makes things easier for Windows user by wrapping in a single installer
python 2.5 plus numerous useful third-party modules and
applications (including Eclipse + pydev, which is an arguably good
IDE for Python under Windows).
* `Twisted <http://twistedmatrix.com/trac/>`_ is an event-driven
networking engine
(`Download Twisted <http://twistedmatrix.com/trac/>`_)
* `lxml <http://codespeak.net/lxml/>`_ library
(version >=2.2.1) allows working with XML and HTML
(`Download lxml <http://pypi.python.org/pypi/lxml/2.2.1>`_)
* `Postgresql 8.4 <http://www.postgresql.org/>`_,
an object-relational database system
(`Download Postgresql <http://www.enterprisedb.com/products/pgdownload.do#windows>`_)
and its python drivers
(`Download psycopg <http://www.stickpeople.com/projects/python/win-psycopg/#Version2>`_)
* A recent version of `gettext`
(`Download gettext <http://download.logilab.org/pub/gettext/gettext-0.17-win32-setup.exe>`_).
* `rql <http://www.logilab.org/project/rql>`_,
the recent version of the Relationship Query Language parser
(`Download rql <http://download.logilab.org/pub/rql/rql-0.26.3.win32-py2.5.exe>`_).
Install optional elements
-------------------------
We recommend you to install the following elements. They are not
mandatory but they activate very interesting features in |cubicweb|:
* `Simplejson <http://pypi.python.org/pypi/simplejson/>`_
must be installed if you have python <= 2.5
(`Download simplejson <http://www.osuch.org/python-simplejson%3Awin32>`_).
It is included in the Standard library from Python >= 2.6.
* `Pyro <http://www.xs4all.nl/~irmen/pyro3/>`_
enables remote access to cubicweb repository instances.
It also allows the client and the server not running on the same machine
(`Download Pyro <http://www.xs4all.nl/~irmen/pyro3/download/>`_).
* `python-ldap <http://pypi.python.org/pypi/python-ldap>`_
provides access to LDAP/Active directory directories
(`Download python-ldap <http://www.osuch.org/python-ldap>`_).
* `graphviz <http://www.graphviz.org/>`_
which allow schema drawings.
(`Download graphviz <http://www.graphviz.org/Download_windows.php>`_).
It is quite recommended (albeit not mandatory).
Other elements will activate more features once installed. Take a look
at :ref:`InstallDependencies`.
Useful tools
------------
Some additional tools could be useful to develop :ref:`cubes <AvailableCubes>`
with the framework.
* `mercurial <http://mercurial.selenic.com/>`_ and its standard
windows GUI (`TortoiseHG <http://tortoisehg.bitbucket.org/>`_)
allow you to get the source code of |cubicweb| from control version
repositories. So you will be able to get the latest development
version in an easy way
(`Download mercurial <http://bitbucket.org/tortoisehg/stable/wiki/download>`_).
* You can also consider the ssh client `Putty` in order to peruse
mercurial over ssh (`Download <http://www.putty.org/>`_).
* If you are an Eclipse user, mercurial can be integrated using the
`MercurialEclipse` plugin
(`Home page <http://www.vectrace.com/mercurialeclipse/>`_).
Getting the sources
-------------------
There are tow ways to get the sources of |cubicweb| and its
:ref:`cubes <AvailableCubes>`:
* download the latest release (:ref:`SourceInstallation`)
* get the development version using Mercurial
(:ref:`MercurialInstallation`)
Environment variables
---------------------
You will need some convenience environment variables once all is set up. These
variables are settable through the GUI by getting at the `System properties`
window (by righ-clicking on `My Computer` -> `properties`).
In the `advanced` tab, there is an `Environment variables` button. Click on
it. That opens a small window allowing edition of user-related and system-wide
variables.
We will consider only user variables. First, the ``PATH`` variable. Assuming
you are logged as user *Jane*, add the following paths, separated by
semi-colons::
C:\Documents and Settings\Jane\My Documents\Python\cubicweb\cubicweb\bin
C:\Program Files\Graphviz2.24\bin
The ``PYTHONPATH`` variable should also contain::
C:\Documents and Settings\Jane\My Documents\Python\cubicweb\
From now, on a fresh `cmd` shell, you should be able to type::
cubicweb-ctl list
... and get a meaningful output.
Running an instance as a service
--------------------------------
This currently assumes that the instances configurations is located at
``C:\\etc\\cubicweb.d``. For a cube 'my_instance', you will find
``C:\\etc\\cubicweb.d\\my_instance\\win32svc.py``.
Now, register your instance as a windows service with::
win32svc install
Then start the service with::
net start cubicweb-my_instance
