可爱的食谱 1.0.0

创建目录

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = data-dir
... find-links = http://download.zope.org/distribution
...
... [data-dir]
... recipe = lovely.recipe:mkdir
... path = ${buildout:directory}/mystuff
... """)
>>> print system(buildout),
Installing data-dir.
data-dir: Creating directory /sample-buildout/mystuff

>>> ls(sample_buildout)
-  .installed.cfg
d  bin
-  buildout.cfg
d  develop-eggs
d  eggs
d  mystuff
d  parts

如果我们更改目录名，旧目录（“mystuff”）不会被删除。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = data-dir
... find-links = http://download.zope.org/distribution
...
... [data-dir]
... recipe = lovely.recipe:mkdir
... path = ${buildout:directory}/otherdir
... """)
>>> print system(buildout),
Uninstalling data-dir.
Installing data-dir.
data-dir: Creating directory /sample-buildout/otherdir

>>> ls(sample_buildout)
-  .installed.cfg
d  bin
-  buildout.cfg
d  develop-eggs
d  eggs
d  mystuff
d  otherdir
d  parts

我们还可以创建一个完整路径。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = data-dir
... find-links = http://download.zope.org/distribution
...
... [data-dir]
... recipe = lovely.recipe:mkdir
... path = ${buildout:directory}/with/subdir
... """)
>>> print system(buildout),
Uninstalling data-dir.
Installing data-dir.
data-dir: Cannot create /sample-buildout/with/subdir. /sample-buildout/with is not a directory.
While:
  Installing data-dir.
Error: Invalid Path

但我们需要显式激活此功能。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = data-dir
... find-links = http://download.zope.org/distribution
...
... [data-dir]
... recipe = lovely.recipe:mkdir
... createpath = True
... path = ${buildout:directory}/with/subdir
... """)
>>> print system(buildout),
Installing data-dir.
data-dir: Creating parent directory /sample-buildout/with
data-dir: Creating directory /sample-buildout/with/subdir

>>> ls(sample_buildout)
-  .installed.cfg
d  bin
-  buildout.cfg
d  develop-eggs
d  eggs
d  mystuff
d  otherdir
d  parts
d  with
>>> ls(sample_buildout + '/with')
d  subdir

没有更新方法，因此在更新时使用安装方法，目录将被重新创建。

>>> rmdir(sample_buildout + '/with')
>>> print system(buildout),
Updating data-dir.
The recipe for data-dir doesn't define an update method. Using its install method.
data-dir: Creating parent directory /sample-buildout/with
data-dir: Creating directory /sample-buildout/with/subdir

如果我们以root身份运行，可以更改创建的目录的所有者。这在mkdir-root.txt中进行了测试。

如果不是以root身份运行，设置所有者将是一个错误

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = data-dir
... find-links = http://download.zope.org/distribution
...
... [data-dir]
... recipe = lovely.recipe:mkdir
... createpath = True
... path = ${buildout:directory}/another/with/subdir
... owner = nobody
... """)
>>> print system(buildout),
While:
  Installing.
  Getting section data-dir.
  Initializing part data-dir.
Error: Only root can change the owner to nobody.

当用户不存在时是一个错误

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = data-dir
... find-links = http://download.zope.org/distribution
...
... [data-dir]

... owner = someuser
... """)
>>> print system(buildout),
While:
  Installing.
  Getting section data-dir.
  Initializing part data-dir.
Error: The user someuser does not exist.

创建文件

mkfile配方可以创建一个或多个具有给定路径、内容和权限的文件。

请注意，父目录必须存在，否则会引发用户错误。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = script
...
... [script]
... recipe = lovely.recipe:mkfile
... path = /x/y/file.sh
... content = hoschi
... mode = 0755
... """)
>>> print system(buildout)
Uninstalling data-dir.
Installing script.
script: Cannot create file /x/y/file.sh. /x/y is not a directory.
While:
  Installing script.
Error: Invalid path

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = script
...
... [script]
... recipe = lovely.recipe:mkfile
... path = file.sh
... content = hoschi
... mode = 0755
... """)
>>> print system(buildout)
Installing script.
script: Writing file /sample-buildout/file.sh
<BLANKLINE>

>>> ls(sample_buildout)
-  .installed.cfg
d  bin
-  buildout.cfg
d  develop-eggs
d  eggs
-  file.sh
d  mystuff
d  otherdir
d  parts
d  with

内容将被写入到文件中。

>>> cat(sample_buildout, 'file.sh')
hoschi

并设置模式。

>>> import os, stat
>>> path = os.path.join(sample_buildout, 'file.sh')
>>> oct(stat.S_IMODE(os.stat(path)[stat.ST_MODE]))
'0755'

如果我们更改文件名，旧文件将被删除。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = script
...
... [script]
... recipe = lovely.recipe:mkfile
... path = newfile.sh
... content = hoschi
... mode = 0755
... """)
>>> print system(buildout)
Uninstalling script.
Installing script.
script: Writing file /sample-buildout/newfile.sh
<BLANKLINE>

>>> ls(sample_buildout)
-  .installed.cfg
d  bin
-  buildout.cfg
d  develop-eggs
d  eggs
d  mystuff
-  newfile.sh
d  otherdir
d  parts
d  with

我们还可以指定为文件创建路径。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = script
...
... [script]
... recipe = lovely.recipe:mkfile
... createpath = On
... path = subdir/for/file/file.sh
... content = hoschi
... mode = 0755
... """)
>>> print system(buildout)
Uninstalling script.

script: Creating directory /sample-buildout/subdir/for/file
script: Writing file /sample-buildout/subdir/for/file/file.sh

>>> ls(sample_buildout + '/subdir/for/file')
-  file.sh

... parts = i18n
... index = http://download.zope.org/zope3.4
... offline = true
