|
|
Load a JSON file containing an array, string, or hash, and return the data
|
|
in the corresponding native data type.
|
|
The second parameter is the default value. It will be returned if the file
|
|
was not found or could not be parsed.
|
|
|
|
For example:
|
|
|
|
$myhash = loadjson('/etc/puppet/data/myhash.json')
|
|
$myhash = loadjson('no-file.json', {'default' => 'value'})
|
