module: unarchive
version_added: '1.4'
short_description: Unpacks an archive after (optionally) copying it from the local machine
description:
     - The M(ansible.builtin.unarchive) module unpacks an archive. It will not unpack a compressed file that does not contain an archive.
     - By default, it will copy the source file from the local system to the target before unpacking.
     - Set O(remote_src=yes) to unpack an archive which already exists on the target.
     - If checksum validation is desired, use M(ansible.builtin.get_url) or M(ansible.builtin.uri) instead to fetch the file and set O(remote_src=yes).
     - For Windows targets, use the M(community.windows.win_unzip) module instead.
options:
  src:
    description:
      - If O(remote_src=no) (default), local path to archive file to copy to the target server; can be absolute or relative. If O(remote_src=yes), path on the
        target server to existing archive file to unpack.
      - If O(remote_src=yes) and O(src) contains V(://), the remote machine will download the file from the URL first. (version_added 2.0). This is only for
        simple cases, for full download support use the M(ansible.builtin.get_url) module.
    type: path
    required: true
  dest:
    description:
      - Remote absolute path where the archive should be unpacked.
      - The given path must exist. Base directory is not created by this module.
    type: path
    required: true
  copy:
    description:
      - If true, the file is copied from local controller to the managed (remote) node, otherwise, the plugin will look for src archive on the managed machine.
      - This option has been deprecated in favor of O(remote_src).
      - This option is mutually exclusive with O(remote_src).
    type: bool
    default: yes
  creates:
    description:
      - If the specified absolute path (file or directory) already exists, this step will B(not) be run.
      - The specified absolute path (file or directory) must be below the base path given with O(dest).
    type: path
    version_added: "1.6"
  io_buffer_size:
    description:
      - Size of the volatile memory buffer that is used for extracting files from the archive in bytes.
    type: int
    default: 65536
    version_added: "2.12"
  list_files:
    description:
      - If set to True, return the list of files that are contained in the tarball.
    type: bool
    default: no
    version_added: "2.0"
  exclude:
    description:
      - List the directory and file entries that you would like to exclude from the unarchive action.
      - Mutually exclusive with O(include).
    type: list
    default: []
    elements: str
    version_added: "2.1"
  include:
    description:
      - List of directory and file entries that you would like to extract from the archive. If O(include)
        is not empty, only files listed here will be extracted.
      - Mutually exclusive with O(exclude).
    type: list
    default: []
    elements: str
    version_added: "2.11"
  keep_newer:
    description:
      - Do not replace existing files that are newer than files from the archive.
    type: bool
    default: no
    version_added: "2.1"
  extra_opts:
    description:
      - Specify additional options by passing in an array.
      - Each space-separated command-line option should be a new element of the array. See examples.
      - Command-line options with multiple elements must use multiple lines in the array, one for each element.
    type: list
    elements: str
    default: []
    version_added: "2.1"
  remote_src:
    description:
      - Set to V(true) to indicate the archived file is already on the remote system and not local to the Ansible controller.
      - This option is mutually exclusive with O(copy).
    type: bool
    default: no
    version_added: "2.2"
  validate_certs:
    description:
      - This only applies if using a https URL as the source of the file.
      - This should only set to V(false) used on personally controlled sites using self-signed certificate.
      - Prior to 2.2 the code worked as if this was set to V(true).
    type: bool
    default: yes

    check_mode:

    diff_mode:
      support: partial
      details: Uses gtar's C(--diff) arg to calculate if changed or not. If this C(arg) is not supported, it will always unpack the archive.

    safe_file_operations:
      support: none
    vault:
      support: full
todo:
    - Re-implement tar support using native tarfile module.
    - Re-implement zip support using native zipfile module.
notes:
    - Requires C(zipinfo) and C(gtar)/C(unzip) command on target host.
    - Requires C(zstd) command on target host to expand I(.tar.zst) files.
    - Can handle I(.zip) files using C(unzip) as well as I(.tar), I(.tar.gz), I(.tar.bz2), I(.tar.xz), and I(.tar.zst) files using C(gtar).
    - Does not handle I(.gz) files, I(.bz2) files, I(.xz), or I(.zst) files that do not contain a I(.tar) archive.
    - Existing files/directories in the destination which are not in the archive
      are not touched. This is the same behavior as a normal archive extraction.
    - Existing files/directories in the destination which are not in the archive
      are ignored for purposes of deciding if the archive should be unpacked or not.
