ZC Buildout recipe to execute a commande line

Project description

What is iw.recipe.cmd ?

This recipe is used to run one or more command lines

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 = 'touch %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)

Ok, so now we can touch a file:

>>> print system(buildout)
Installing cmds.

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

And remove it:

>>> test_file = join(sample_buildout, 'test.txt')
>>> 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:

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

>>> test_file = join(sample_buildout, 'test.txt')
>>> 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 os.listdir(sample_buildout)
...   >>> shutil.rmtree(os.path.join(sample_buildout, "bin"))
...   >>> print 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']
['.installed.cfg', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
Installing py2.
True
