The value of this option must be either true or false. If the value

only effective when an egg is installed. If a zipped egg already

Controlling which Python to use
-------------------------------
The following assumes that your $HOME/.buildout/default.cfg has
python2.3 and python2.4 sections that define Python 2.3 and Python 2.4
executables.
We can specify the python to use by specifying the name of a section
to read the Python executable from. The default is the section
defined by the python buildout option.
We have a directory with some sample eggs:
>>> ls(sample_eggs)
- demo-0.1-py2.3.egg
- demo-0.1-py2.4.egg
- demo-0.2-py2.3.egg
- demo-0.2-py2.4.egg
- demo-0.3-py2.3.egg
- demo-0.3-py2.4.egg
- demoneeded-1.0-py2.3.egg
- demoneeded-1.0-py2.4.egg
We have a sample buildout. Let's update it's configuration file to
install the demo package using Python 2.3.
>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = demo
... eggs-directory = eggs
...
... [demo]
... recipe = zc.recipe.egg
... distribution = demo <0.3
... find-links = %s
... python = python2.3
... """ % sample_eggs)
In our default.cfg file in the .buildout subdirectiry of our
directory, we have something like::
[python2.3]
executable = /usr/bin/python
[python2.4]
executable = /usr/local/bin/python2.4
(Of course, the paths will vary from system to system.)
Now, if we run the buildout:
>>> import os
>>> os.chdir(sample_buildout)
>>> buildout = os.path.join(sample_buildout, 'bin', 'buildout')
>>> print system(buildout),
we'll get the Python 2.3 eggs for demo and demoneeded:
>>> ls(sample_buildout, 'eggs')
- demo-0.2-py2.3.egg
- demoneeded-1.0-py2.3.egg
And the generated scripts invoke Python 2.3:
>>> f = open(os.path.join(sample_buildout, 'bin', 'demo'))
>>> f.readline().strip() == '#!' + python2_3_executable
True
>>> print f.read(),
