==============

python-systemd-dbus python wrapper for `systemd`_ system and session manager dbus
interfaces.

.. systemd: http://www.freedesktop.org/wiki/Software/systemd

Basic usage
===========

>>> from systemd_dbus.manager import Manager
>>> manager = Manager()

# List all units
>>> for unit in manager.list_units():
...    print unit.properties.Id
...    print unit.properties.Description
... 
nfs-server.service
LSB: Kernel NFS server support
virtualbox.service
LSB: VirtualBox Linux kernel module
mandi.service
LSB: Network monitoring daemon
crond.service
LSB: run cron daemon
...

>>> unit = manager.get_unit('crond.service')

# crond is running
>>> print unit.properties.LoadState, unit.properties.ActiveState, unit.properties.SubState
loaded active running

# Let's stop crond
>>> unit.stop('fail')
<systemd_dbus.job.Job object at 0x7fa57ba03a90>

# is crond running? why I stop it!!
>>> print unit.properties.LoadState, unit.properties.ActiveState, unit.properties.SubState
loaded active running

# We want o loop!
>>> import gobject
>>> gobject.MainLoop().run()
...
KeyboardInterrupt

# Now Unit properties is updated!
>>> print unit.properties.LoadState, unit.properties.ActiveState, unit.properties.SubState
loaded inactive dead

# Let's start crond
>>> unit.start('fail')
<systemd_dbus.job.Job object at 0x7fa57ba03950>

# Remember we want o loop!
>>> print unit.properties.LoadState, unit.properties.ActiveState, unit.properties.SubState
loaded inactive dead

# The loop!
>>> gobject.MainLoop().run()
...
KeyboardInterrupt

# Updated!
>>> print unit.properties.LoadState, unit.properties.ActiveState, unit.properties.SubState
loaded active running
