module: pacman
short_description: Manage packages with I(pacman)
description:
- Manage packages with the I(pacman) package manager, which is used by Arch Linux and its variants.
author:
- Indrajit Raychaudhuri (@indrajitr)
- Aaron Bull Schaefer (@elasticdog) <aaron@elasticdog.com>
- Maxime de Roucy (@tchernomax)
options:
name:
description:
- Name or list of names of the package(s) or file(s) to install, upgrade, or remove.
Can't be used in combination with C(upgrade).
aliases: [ package, pkg ]
type: list
elements: str
state:
description:
- Whether to install (C(present) or C(installed), C(latest)), or remove (C(absent) or C(removed)) a package.
- C(present) and C(installed) will simply ensure that a desired package is installed.
- C(latest) will update the specified package if it is not of the latest available version.
- C(absent) and C(removed) will remove the specified package.
default: present
choices: [ absent, installed, latest, present, removed ]
type: str
force:
description:
- When removing package, force remove package, without any checks.
Same as `extra_args="--nodeps --nodeps"`.
When update_cache, force redownload repo databases.
Same as `update_cache_extra_args="--refresh --refresh"`.
default: no
type: bool
executable:
description:
- Name of binary to use. This can either be C(pacman) or a pacman compatible AUR helper.
- Beware that AUR helpers might behave unexpectedly and are therefore not recommended.
default: pacman
type: str
version_added: 3.1.0
extra_args:
description:
- Additional option to pass to pacman when enforcing C(state).
default:
type: str
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.
default: no
type: bool
aliases: [ update-cache ]
update_cache_extra_args:
description:
- Additional option to pass to pacman when enforcing C(update_cache).
default:
type: str
upgrade:
description:
- Whether or not to upgrade the whole system.
Can't be used in combination with C(name).
default: no
type: bool
upgrade_extra_args:
description:
- Additional option to pass to pacman when enforcing C(upgrade).
default:
type: str
notes:
- When used with a C(loop:) each package will be processed individually,
it is much more efficient to pass the list directly to the I(name) option.
- To use an AUR helper (I(executable) option), a few extra setup steps might be required beforehand.
For example, a dedicated build user with permissions to install packages could be necessary.
