用于bdb configure/make/make install的zc构建方法
ro.bdb.cmmi的Python项目详细描述
我们有一个带有演示足球的档案：
>>> ls(distros) - foo.tgz
让我们更新一个示例构建来安装它：
>>> write('buildout.cfg',
... """
... [buildout]
... parts = foo
...
... [foo]
... recipe = ro.bdb.cmmi
... url = file://%s/foo.tgz
... """ % distros)
我们使用url选项指定存档的位置。
如果运行构建，则运行存档中的配置脚本。 它会创建一个make文件，该文件也会运行：
>>> print system('bin/buildout'),
Installing foo.
foo: Downloading .../distros/foo.tgz
foo: Unpacking and configuring
configuring foo --prefix=/sample-buildout/parts/foo
echo building foo
building foo
echo installing foo
installing foo
配方还会创建零件目录：
>>> ls(sample_buildout, 'parts') d foo
如果我们再次运行buildout，将调用update方法，它 什么也不做：
>>> print system('bin/buildout'),
Updating foo.
您可以提供额外的配置选项：
>>> write('buildout.cfg', ... """ ... [buildout] ... parts = foo ... ... [foo] ... recipe = ro.bdb.cmmi ... url = file://%s/foo.tgz ... extra_options = -a -b c ... """ % distros)>>> print system('bin/buildout'), Uninstalling foo. Installing foo. foo: Downloading .../distros/foo.tgz foo: Unpacking and configuring configuring foo --prefix=/sample-buildout/parts/foo -a -b c echo building foo building foo echo installing foo installing foo
配方设置了位置选项，其他人可以读取 配方，到安装部件的位置：
>>> cat('.installed.cfg')
... # doctest: +ELLIPSIS
[buildout]
installed_develop_eggs =
parts = foo
<BLANKLINE>
[foo]
__buildout_installed__ = /sample-buildout/parts/foo
...
extra_options = -a -b c
location = /sample-buildout/parts/foo
...
有时在构建包之前需要修补源代码。 您可以指定要应用的修补程序的名称和（可选）修补程序选项：
首先，让我们编写一个补丁文件：
>>> import sys
>>> mkdir('patches')
>>> write('patches/config.patch',
... """--- configure
... +++ /dev/null
... @@ -1,13 +1,13 @@
... #!%s
... import sys
... -print "configuring foo", ' '.join(sys.argv[1:])
... +print "configuring foo patched", ' '.join(sys.argv[1:])
...
... Makefile_template = '''
... all:
... -\techo building foo
... +\techo building foo patched
...
... install:
... -\techo installing foo
... +\techo installing foo patched
... '''
...
... open('Makefile', 'w').write(Makefile_template)
...
... """ % sys.executable)
现在我们创建一个buildout.cfg文件。注意：如果没有补丁选项 默认情况下，将追加-p0。
>>> write('buildout.cfg', ... """ ... [buildout] ... parts = foo ... ... [foo] ... recipe = ro.bdb.cmmi ... url = file://%s/foo.tgz ... patch = ${buildout:directory}/patches/config.patch ... patch_options = -p0 ... """ % distros)>>> print system('bin/buildout'), Uninstalling foo. Installing foo. foo: Downloading .../distros/foo.tgz foo: Unpacking and configuring patching file configure configuring foo patched --prefix=/sample_buildout/parts/foo echo building foo patched building foo patched echo installing foo patched installing foo patched
