Overview

This recipe allows to set environment variables during the execution of a buildout.

There isn’t any options for this recipe: all options in the part are set as environment variables.

The environment variables are set during the initialization of the Recipe instance, i.e. after buildout.cfg is read but before any recipe is installed or updated.

Example usage

We’ll start by creating a buildout that uses the recipe:

>>> write('buildout.cfg',
... """
... [buildout]
... parts = environment print
...
... [some-section]
... some-option = value2
...
... [environment]
... recipe = collective.recipe.environment
... var1 = value1
... var2 = ${some-section:some-option}
...
... [print]
... recipe = mr.scripty
... install =
...     ... import os
...     ... for var in ('var1', 'var2'):
...     ...     print '%s = %s' % (var, os.environ[var])
...     ... return []
... """)

The mr.scripty recipe is used to print out the values of the environment variables.

Running the buildout gives us:

>>> print 'start', system(buildout)
start...
var1 = value1
var2 = value2
