module: svr4pkg
short_description: Manage Solaris SVR4 packages
description:
    - Manages SVR4 packages on Solaris 10 and 11.
    - These were the native packages on Solaris <= 10 and are available
      as a legacy feature in Solaris 11.
    - Note that this is a very basic packaging system. It will not enforce
      dependencies on install or remove.
version_added: 0.9
author: Boyd Adamson
options:
  name:
    description:
      - Package name, e.g. C(SUNWcsr)
    required: true

  state:
    description:
      - Whether to install (C(present)), or remove (C(absent)) a package.
      - If the package is to be installed, then C(src) is required.
      - The SVR4 package system doesn't provide an upgrade operation. You need to uninstall the old, then install the new package.
    required: true
    choices: ["present", "absent"]

  src:
    description:
      - Specifies the location to install the package from. Required when C(state=present).
      - Can be any path acceptable to the C(pkgadd) command's C(-d) option. e.g.: C(somefile.pkg), C(/dir/with/pkgs), C(http:/server/mypkgs.pkg).
      - If using a file or directory, they must already be accessible by the host. See the I(copy) module for a way to get them there.
  proxy:
    description:
      - HTTP[s] proxy to be used if C(src) is a URL.

examples:
  - code: svr4pkg name=CSWcommon src=/tmp/cswpkgs.pkg state=present
    description: Install a package from an already copied file
  - code: svr4pkg name=CSWpkgutil src=http://get.opencsw.org/now state=present
    description: Install a package directly from an http site
  - code: svr4pkg name=SUNWgnome-sound-recorder state=absent
    description: Ensure that a package is not installed.
