zc.recipe.script 1.0.2

许多部署提供了将配置绑定到 软件。这样做通常是为了更容易使用特定的 软件的部署。

传统的unix文件层次结构并不能真正提供 此类脚本的共享位置；zc.recipe.deployment:script recipe 在部署的bin目录中生成这些脚本，但是 而是将生成的脚本与部署本身关联起来。

配方的选项与 egg：脚本配方，添加了所需的部署 设置。使用部署中的etc目录而不是 构建的bin目录。这允许部署特定的信息 通过初始化设置嵌入到脚本中。

让我们看一个简单的案例。我们需要一个包裹 控制台脚本入口点：

>>> write('setup.py', '''\
... from setuptools import setup
... setup(
...     name="testpkg",
...     package_dir={"": "src"},
...     py_modules=["testmodule"],
...     zip_safe=False,
...     entry_points={
...         "console_scripts": [
...             "myscript=testmodule:main",
...             ],
...         },
...     )
... ''')

>>> mkdir('src')
>>> write('src', 'testmodule.py', '''\
... some_setting = "42"
... def main():
...     print some_setting
... ''')

>>> write('buildout.cfg',
... '''
... [buildout]
... develop = .
... parts = somescript
...

... recipe = zc.recipe.deployment

... recipe = zc.recipe.script
... deployment = mydep
... eggs = testpkg
... scripts = myscript
... initialization =
...     import testmodule
...     testmodule.some_setting = "24"
... ''' % (sample_buildout, user, user))

>>> print system(join('bin', 'buildout')), # doctest: +NORMALIZE_WHITESPACE
