def get(key, default='', merge=False, delimiter=':'):
'''
.. versionadded:: 0.14
Attempt to retrieve the named value from pillar, if the named value is not
available return the passed default. The default return is an empty string.
If the merge parameter is set to ``True``, the default will be recursively
merged into the returned pillar data.
The value can also represent a value in a nested dict using a ":" delimiter
for the dict. This means that if a dict in pillar looks like this::
{'pkg': {'apache': 'httpd'}}
To retrieve the value associated with the apache key in the pkg dict this
key can be passed::
pkg:apache
merge
Specify whether or not the retrieved values should be recursively
merged into the passed default.
.. versionadded:: 2014.7.0
delimiter
Specify an alternate delimiter to use when traversing a nested dict
.. versionadded:: 2014.7.0
CLI Example:
.. code-block:: bash
salt '*' pillar.get pkg:apache
'''
