NAME

Ansible::Util::Vars

VERSION

version 0.001

SYNOPSIS

  $vars = Ansible::Util::Vars->new;
  
  $href = $vars->getVar('foo');
  $href = $vars->getVars(['foo', 'bar']);
  $val  = $vars->getValue('foo');
   

DESCRIPTION

Read Ansible runtime vars into native Perl.

To indicate which vars to read, you use the variable dot notation similar to what is described in the Ansible documentation. Further information about the Perl implementation can be found in Hash::DotPath.

An optional cache layer is used to speed up multiple invocations.

clearCache()

Clears any cached vars.

usage:

  $vars->clearCache;

args:

none

disableCache()

Disables caching.

usage:

  $vars->disableCache;

returns:

The previous value of the attribute 'cacheEnabled'.

args:

none

enableCache()

Enables caching.

usage:

  $vars->enableCache;

returns:

The previous value of the attribute 'cacheEnabled'.

args:

none

getValue()

Fetches the value of the specified var.

usage:

  $val = $vars->getValue($path);
  

returns:

The value found at the specified path.

args:

path

The path to the variable in dot notation. See Hash::DotPath for more info.

type: Str

required: yes

getVar($path)

Fetches the variable found at the specified path.

usage:

  $href = $vars->getVar($path);
  

returns:

A hash reference containing the requested var. Note that this also includes each of the elements in the path. Examples:

  $href = $vars->getVar('foo.bar');
  Data::Printer::p($href);
  \ {
    foo   {
        bar   "somevalue"
    }
  }
  
  $href = $vars->getVar('biz.0.baz');

    biz   [
        [0] {
            baz   "anothervalue"
        }

required: yes

getVars([$paths])

Fetches the variables found at the specified path.

usage:

  $href = $vars->getVars(['foo.0.bar', 'biz']);
  

returns:

A hash reference containing the requested vars. The characteristics are the same as described in "getVar" except that the vars are merged into a single hash ref.

args:

path

The path to the variable in dot notation. See Hash::DotPath for more info.
