- Manage binary packages for FreeBSD using 'pkgng' which is available in versions after 9.0.

options:
name:
description:
- Name or list of names of packages to install/remove.
- "With O(name=*), O(state=latest) will operate, but O(state=present) and O(state=absent) will be noops."
required: true
aliases: [pkg]
type: list
elements: str
state:
description:
- State of the package.
choices: [ 'present', 'latest', 'absent' ]
required: false
default: present

description:
- Use local package base instead of fetching an updated one.
type: bool
required: false
default: false
annotation:
description:
- A list of keyvalue-pairs of the form
C(<+/-/:><key>[=<value>]). A V(+) denotes adding an annotation, a
V(-) denotes removing an annotation, and V(:) denotes modifying an
annotation.
If setting or modifying annotations, a value must be provided.
required: false
type: list
elements: str
pkgsite:
description:
- For pkgng versions before 1.1.4, specify packagesite to use
for downloading packages. If not specified, use settings from
C(/usr/local/etc/pkg.conf).
- For newer pkgng versions, specify a the name of a repository
configured in C(/usr/local/etc/pkg/repos).
required: false
type: str
rootdir:
description:
- For pkgng versions 1.5 and later, pkg will install all packages
within the specified root directory.
- Can not be used together with O(chroot) or O(jail) options.
required: false
type: path
chroot:
description:
- Pkg will chroot in the specified environment.
- Can not be used together with O(rootdir) or O(jail) options.
required: false
type: path
jail:
description:
- Pkg will execute in the given jail name or id.
- Can not be used together with O(chroot) or O(rootdir) options.
type: str
autoremove:
description:
- Remove automatically installed packages which are no longer needed.
required: false
type: bool
default: false
ignore_osver:
description:
- Ignore FreeBSD OS version check, useful on -STABLE and -CURRENT branches.
- Defines the E(IGNORE_OSVERSION) environment variable.
required: false
type: bool
default: false
version_added: 1.3.0
author: "bleader (@bleader)"
notes:
- When using pkgsite, be careful that already in cache packages won't be downloaded again.
- When used with a C(loop:) each package will be processed individually,
it is much more efficient to pass the list directly to the O(name) option.
