A recipe to simulate eggs for non eggs modules installed at python level

Project description


Detailed Documentation


Sometimes you can’t add eggs through your buildout engine, for example if some dev libraries are lacking on your system, or are too old, etc. But you can install module directly on your system. Then, whereas you get all you need in your python environment, your buildout may fail because egg is lacking.

This recipe will simulate an egg installed on your system has been added as an egg in your buildout. This is bad. Don’t use this recipe :)

Supported options

The recipe supports the following options:


The list of eggs you want to mock, with their version number, as for example :

mocked-eggs =
python-ldap=2.3.10 Markdown=1.7

Example usage

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

>>> write('buildout.cfg',
... """
... [buildout]
... parts = mocked-eggs-test
...         zopepy
... eggs = mocked1
...        mocked2
... [mocked-eggs-test]
... recipe = collective.recipe.mockedeggs
... mocked-eggs =
...      mocked1=1.0
...      mocked2=2.0
... [zopepy]
... recipe = zc.recipe.egg
... interpreter = zopepy
... eggs = mocked1
...        mocked2
... """)
Running the buildout gives us::
>>> print 'start...\n', system(buildout)
Installing mocked-eggs-test.
mocked-eggs-test: Mocked eggs mocked1, mocked2.
>>> import os
>>> os.path.exists('mocked-eggs-test')
    >>> os.path.exists('mocked-eggs-test/fake-mocked1')
    >>> os.path.exists('mocked-eggs-test/fake-mocked2')
>>> setup1 = open('mocked-eggs-test/fake-mocked1/').read()
>>> '1.0' in setup1
>>> "'mocked1'" in setup1
>>> binary = open('bin/zopepy', 'r').read()
>>> 'mocked-eggs-test/fake-mocked1' in binary
