Detailed Documentation

Supported options

The recipe supports the following options:

on_install

true if the commands must run on install

on_update

true if the commands must run on update

cmds

a set of command lines

shell

a valid interpreter (POSIX only)

Example usage

We need a config file:

>>> cfg = """
... [buildout]
... parts = cmds
...
... [cmds]
... recipe = iw.recipe.cmd
... on_install=true
... cmds= %s
... """

>>> test_file = join(sample_buildout, 'test.txt')
>>> cmds = 'echo "bouh" > %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)

Ok, so now we can touch a file for testing:

>>> print system(buildout)
Installing cmds.

>>> 'test.txt' in os.listdir(sample_buildout)
True

And remove it:

>>> test_file = join(sample_buildout, 'test.txt')
>>> if sys.platform == 'win32':
...    cmds = 'del %s' % test_file
... else:
...    cmds = 'rm -f %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)

>>> print system(buildout)
Uninstalling cmds.
Installing cmds.

>>> 'test.txt' in os.listdir(sample_buildout)
False

We can run more than one commands:

>>> if sys.platform == 'win32':
...     cmds = '''
... echo "bouh" > %s
... del %s
... ''' % (test_file, test_file)
... else:
...     cmds = '''
... echo "bouh" > %s
... rm -f %s
... ''' % (test_file, test_file)

>>> test_file = join(sample_buildout, 'test.txt')
>>> if sys.platform == 'win32':
...     cmds = 'del %s' % test_file
... else:
...     cmds = 'rm -f %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)

>>> print system(buildout)
Updating cmds.

>>> 'test.txt' in os.listdir(sample_buildout)
False

We can also run some python code:

>>> cfg = """
... [buildout]
... parts = py py2
...
... [py]
... recipe = iw.recipe.cmd:py
... on_install=true
... cmds=
...   >>> sample_buildout = buildout.get('directory', '.')
...   >>> print sorted(os.listdir(sample_buildout))
...   >>> os.remove(os.path.join(sample_buildout, ".installed.cfg"))
...   >>> print sorted(os.listdir(sample_buildout))
... [py2]
... recipe = iw.recipe.cmd:py
... on_install=true
... cmds=
...   >>> def myfunc(value):
...   ...     return value and True or False
...   >>> v = 20
...   >>> print myfunc(v)
... """

>>> write(sample_buildout, 'buildout.cfg', cfg)

Ok, so now we run it:

>>> print system(buildout)
Uninstalling cmds.
Installing py.
['.installed.cfg', 'bin', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
['bin', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
Installing py2.
True
