iw.recipe.cmd package

This recipe is used to run one or more command lines

We need some buildout vars:

>>> import os
>>> join = os.path.join
>>> data_dir = join(test_dir, 'data')
>>> parts_dir = join(data_dir, 'parts')
>>> buildout = {'instance': {'location': test_dir},
...             'buildout': {'directory': test_dir,
...             'parts-directory': test_dir}}
>>> name = 'cmds'

Ok, so now we can touch a file in data_dir:

>>> test_file = join(data_dir, 'test.txt')

>>> options = {'cmds': 'touch %s' % test_file}

>>> from iw.recipe.cmd import Recipe
>>> recipe = Recipe(buildout, name, options)
>>> path = recipe.install()
>>> 'test.txt' in os.listdir(data_dir)
True

And remove it:

>>> options = {'cmds': 'rm -f %s' % test_file}
>>> recipe = Recipe(buildout, name, options)
>>> path = recipe.install()
>>> 'test.txt' in os.listdir(data_dir)
False

We can run more than one commands:

>>> cmds = '''
... touch %s
... rm -f %s
... ''' % (test_file, test_file)

>>> recipe = Recipe(buildout, name, options)
>>> path = recipe.install()
>>> 'test.txt' in os.listdir(data_dir)
False
