详细文档

让我们创建一个鸡蛋用于我们的测试：

>>> mkdir('myegg')
>>> write('myegg', 'setup.py',
... '''
... from setuptools import setup
... setup(name='myegg', version='1.0',)
... ''')
>>> write('myegg', 'README', '')
>>> print_(system(buildout+' setup myegg bdist_egg')), # doctest: +ELLIPSIS
Running setup script 'myegg...
...

>>> mkdir('baregg')
>>> write('baregg', 'setup.py',
... '''
... from setuptools import setup
... setup(name='baregg', version='1.0',)
... ''')
>>> write('baregg', 'README', '')
>>> print_(system(buildout+' setup baregg bdist_egg')), # doctest: +ELLIPSIS
Running setup script 'baregg...
...

现在让我们创建一个buildout来安装egg并使用buildout.gc:

>>> write('buildout.cfg',
... '''
... [buildout]
... index = http://pypi.python.org/simple
... extensions = buildout.gc
... eggs-directory = ${buildout:directory}/eggs
... parts = foo
... find-links += %s
... [foo]
... recipe = zc.recipe.egg
... eggs = myegg
... ''' % join('myegg', 'dist'))

运行构建将打印有关未使用鸡蛋的信息：

>>> print_(system(buildout)), # doctest: +ELLIPSIS
Installing foo.
Getting distribution for 'myegg'.
...
Don't have a 'old-eggs-directory' or 'old-eggs-remove' set, only reporting
...

当我们只想报告未使用的鸡蛋时，我们省略了old-eggs-directory和old-eggs-remove选项。

>>> write('buildout.cfg',
... '''
... [buildout]
... index = http://pypi.python.org/simple
... extensions = buildout.gc
... eggs-directory = ${buildout:directory}/eggs
... parts = foo
... find-links += %s
... [foo]
... recipe = zc.recipe.egg
... eggs = baregg
... ''' % join('baregg', 'dist'))

>>> print_(system(buildout)) # doctest:+ELLIPSIS
Uninstalling foo.
Installing foo.
Getting distribution for 'baregg'.
Got baregg 1.0.
Don't have a 'old-eggs-directory' or 'old-eggs-remove' set, only reporting
Can add it by adding 'old-eggs-directory = ${buildout:directory}/old-eggs' to your [buildout]
Found unused egg: myegg...
<BLANKLINE>

检查是否确实没有移动或删除任何内容：

>>> assert 'myegg' in  ''.join(os.listdir('eggs'))

如果我们想移动未使用的鸡蛋，只需添加一个old-eggs-directory选项并给出一个目录目标：

>>> write('buildout.cfg',
... '''
... [buildout]
... index = http://pypi.python.org/simple
... extensions = buildout.gc
... eggs-directory = ${buildout:directory}/eggs
... old-eggs-directory = ${buildout:directory}/old-eggs
... parts = foo
... find-links += %s
... [foo]
... recipe = zc.recipe.egg
... eggs = baregg
... ''' % join('baregg', 'dist'))

>>> print_(system(buildout)) # doctest:+ELLIPSIS
Updating foo.
Moved unused egg: myegg...
<BLANKLINE>

检查“myegg”是否确实已移动：

>>> assert 'myegg' not in  ''.join(os.listdir('eggs')), 'myegg has not been moved out of egg dir'
>>> assert 'myegg' in  ''.join(os.listdir('old-eggs')), 'myegg has not been moved to old-egg dir'

而且baregg仍然存在：

>>> assert 'baregg' in  ''.join(os.listdir('eggs')), 'baregg is not present in egg dir'

如果要删除未使用的鸡蛋，只需添加一个old-eggs-remove选项：

>>> write('buildout.cfg',
... '''
... [buildout]
... index = http://pypi.python.org/simple
... extensions = buildout.gc
... eggs-directory = ${buildout:directory}/eggs
... old-eggs-directory = ${buildout:directory}/old-eggs
... old-eggs-remove = true
... parts = foo
... find-links += %s
... [foo]
... recipe = zc.recipe.egg
... eggs = myegg
... ''' % join('myegg', 'dist'))

>>> print_(system(buildout)) # doctest:+ELLIPSIS
Uninstalling foo.
Installing foo.
Getting distribution for 'myegg'.
Got myegg 1.0.
Moved unused egg: baregg...
<BLANKLINE>

检查“baregg”是否确实已被删除：

>>> assert 'baregg' not in  ''.join(os.listdir('eggs')), 'baregg has not been removed'
>>> assert 'baregg' not in  ''.join(os.listdir('old-eggs')), 'baregg has been moved to old-egg dir'

“myegg”仍然存在：

>>> assert 'myegg' in  ''.join(os.listdir('eggs')), 'myegg is not present in egg dir'
