A Buildout recipe to execute commands in the console user interface

Project description

Introduction

https://secure.travis-ci.org/collective/collective.recipe.cmd.png?branch=master

collective.recipe.cmd is a Buildout recipe to execute commands in the console user interface.

Usage

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

uninstall_cmds

a set of command lines executed in the buildout uninstall phase

shell

a valid interpreter (POSIX only)

Example usage

We need a config file:

>>> cfg = """
... [buildout]
... parts = cmds
...
... [cmds]
... recipe = collective.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.
Running uninstall recipe.
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 = collective.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 = collective.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.
Running uninstall recipe.
Installing py.
['.installed.cfg', 'bin', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
['bin', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
Installing py2.
True...

If the shell script generated from the commands returns a non-zero exit/status code then an exception is raised and buildout fails:

>>> cfg = """
... [buildout]
... parts = cmds
...
... [cmds]
... recipe = collective.recipe.cmd
... on_install=true
... cmds= exit 23
... """

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

>>> print(system(buildout))
Uninstalling py2.
Uninstalling py.
Installing cmds...
...CalledProcessError: Command 'sh .../run' returned non-zero exit status 23
