Controlling which Python to use
-------------------------------
The following assumes that you have Python 2.4 installed.
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 link server:
>>> print get(link_server),
<html><body>
<a href="bigdemo-0.1-py2.4.egg">bigdemo-0.1-py2.4.egg</a><br>
<a href="demo-0.1-py2.4.egg">demo-0.1-py2.4.egg</a><br>
<a href="demo-0.2-py2.4.egg">demo-0.2-py2.4.egg</a><br>
<a href="demo-0.3-py2.4.egg">demo-0.3-py2.4.egg</a><br>
<a href="demo-0.4c1-py2.4.egg">demo-0.4c1-py2.4.egg</a><br>
<a href="demoneeded-1.0.zip">demoneeded-1.0.zip</a><br>
<a href="demoneeded-1.1.zip">demoneeded-1.1.zip</a><br>
<a href="demoneeded-1.2c1.zip">demoneeded-1.2c1.zip</a><br>
<a href="extdemo-1.4.zip">extdemo-1.4.zip</a><br>
<a href="index/">index/</a><br>
<a href="other-1.0-py2.4.egg">other-1.0-py2.4.egg</a><br>
</body></html>
We have a sample buildout. Let's update it's configuration file to
install the demo package using Python 2.4.
>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = demo
... eggs-directory = eggs
... index = http://www.python.org/pypi/
...
... [python2.4]
... executable = %(python23)s
...
... [demo]
... recipe = zc.recipe.egg
... eggs = demo <0.3
... find-links = %(server)s
... python = python2.4
... interpreter = py-demo
... """ % dict(server=link_server, python23=other_executable))
Now, if we run the buildout:
>>> import os
>>> os.chdir(sample_buildout)
>>> buildout = os.path.join(sample_buildout, 'bin', 'buildout')
>>> print system(buildout),
Installing demo.
Getting distribution for 'demo<0.3'.
Got demo 0.2.
Getting distribution for 'demoneeded'.
Getting distribution for 'setuptools'.
Got setuptools 0.6.
Got demoneeded 1.2c1.
Generated script '/sample-buildout/bin/demo'.
Generated interpreter '/sample-buildout/bin/py-demo'.
we'll get the Python 2.4 eggs for demo and demoneeded:
>>> ls(sample_buildout, 'eggs')
- demo-0.2-py2.4.egg
- demoneeded-1.2c1-py2.4.egg
d setuptools-0.6-py2.4.egg
d setuptools-0.6-py2.5.egg
- zc.buildout-1.0-py2.5.egg
And the generated scripts invoke Python 2.4:
>>> import sys
>>> if sys.platform == 'win32':
... script_name = 'demo-script.py'
... else:
... script_name = 'demo'
>>> f = open(os.path.join(sample_buildout, 'bin', script_name))
>>> shebang = f.readline().strip()
>>> if shebang[:3] == '#!"' and shebang[-1] == '"':
... shebang = '#!'+shebang[3:-1]
>>> shebang == '#!' + other_executable
True
>>> print f.read(), # doctest: +NORMALIZE_WHITESPACE
