options:
  executable:
    type: str
    description:
      - The path to the bundler executable.
  state:
    type: str
    description:
      - The desired state of the Gem bundle. V(latest) updates gems to the most recent, acceptable version.
    choices: [present, latest]
    default: present
  chdir:
    type: path
    description:
      - The directory to execute the bundler commands from. This directory needs to contain a valid Gemfile or .bundle/ directory.
      - If not specified, it will default to the temporary working directory.
  exclude_groups:
    type: list
    elements: str
    description:
      - A list of Gemfile groups to exclude during operations. This only applies when O(state=present). Bundler considers
        this a 'remembered' property for the Gemfile and will automatically exclude groups in future operations even if O(exclude_groups)
        is not set.
  clean:
    description:
      - Only applies if O(state=present). If set removes any gems on the target host that are not in the gemfile.
    type: bool
    default: false
  gemfile:
    type: path
    description:
      - Only applies if O(state=present). The path to the gemfile to use to install gems.
      - If not specified it will default to the Gemfile in current directory.
  local:
    description:
      - If set only installs gems from the cache on the target host.
    type: bool
    default: false
  deployment_mode:
    description:
      - Only applies if O(state=present). If set it will install gems in C(./vendor/bundle) instead of the default location.
        Requires a C(Gemfile.lock) file to have been created prior.
    type: bool
    default: false
  user_install:
    description:
      - Only applies if O(state=present). Installs gems in the local user's cache or for all users.
    type: bool
    default: true
  gem_path:
    type: path
    description:
      - Only applies if O(state=present). Specifies the directory to install the gems into. If O(chdir) is set then this path
        is relative to O(chdir).
      - If not specified the default RubyGems gem paths will be used.
  binstub_directory:
    type: path
    description:
      - Only applies if O(state=present). Specifies the directory to install any gem bins files to. When executed the bin
        files will run within the context of the Gemfile and fail if any required gem dependencies are not installed. If O(chdir)
        is set then this path is relative to O(chdir).
  extra_args:
    type: str
    description:
      - A space separated string of additional commands that can be applied to the Bundler command. Refer to the Bundler documentation
        for more information.
