short_description: Manage packages with XBPS
description:
- Manage packages with the XBPS package manager.
author:
- "Dino Occhialini (@dinoocch)"
- "Michael Aldridge (@the-maldridge)"
options:
name:
description:
- Name of the package to install, upgrade, or remove.
aliases: [pkg,package]
type: list
elements: str
state:
description:
- Desired state of the package.
default: "present"
choices: ["present", "absent", "latest", "installed", "removed"]
type: str
recurse:
description:
- When removing a package, also remove its dependencies, provided
that they are not required by other packages and were not
explicitly installed by a user.
type: bool
default: no
update_cache:
description:
- Whether or not to refresh the master package lists. This can be
run as part of a package installation or as a separate step.
- Alias C(update-cache) has been deprecated and will be removed in community.general 5.0.0.
aliases: ['update-cache']
type: bool
default: yes
upgrade:
description:
- Whether or not to upgrade whole system
type: bool
default: no
upgrade_xbps:
description:
- Whether or not to upgrade the xbps package when necessary.
Before installing new packages,
xbps requires the user to update the xbps package itself.
Thus when this option is set to C(no),
upgrades and installations will fail when xbps is not up to date.
type: bool
default: yes
version_added: '0.2.0'
