short_description: Edit XFCE4 Configurations
description:
- This module allows for the manipulation of Xfce 4 Configuration with the help of
xfconf-query. Please see the xfconf-query(1) man pages for more details.
options:
channel:
description:
- A Xfconf preference channel is a top-level tree key, inside of the
Xfconf repository that corresponds to the location for which all
application properties/keys are stored. See man xfconf-query(1)
required: yes
type: str
property:
description:
- A Xfce preference key is an element in the Xfconf repository
that corresponds to an application preference. See man xfconf-query(1)
required: yes
type: str
value:
description:
- Preference properties typically have simple values such as strings,
integers, or lists of strings and integers. This is ignored if the state
is "get". For array mode, use a list of values. See man xfconf-query(1)
type: list
elements: raw
value_type:
description:
- The type of value being set. This is ignored if the state is "get".
For array mode, use a list of types.
type: list
elements: str
choices: [ int, uint, bool, float, double, string ]
state:
type: str
description:
- The action to take upon the property/value.
- State C(get) is deprecated and will be removed in community.general 5.0.0. Please use the module M(community.general.xfconf_info) instead.
choices: [ get, present, absent ]
default: "present"
force_array:
description:
- Force array even if only one element
type: bool
default: 'no'
aliases: ['array']
version_added: 1.0.0
disable_facts:
description:
- The value C(false) is no longer allowed since community.general 4.0.0.
- This option will be deprecated in a future version, and eventually be removed.
