.. versionadded:: 0.14.0
Attempt to retrieve the named value from :ref:`in-memory pillar data
<pillar-in-memory>`. If the pillar key is not present in the in-memory
pillar, then the value specified in the ``default`` option (described
below) will be returned.
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 as::
pkg:apache
key
The pillar key to get value from
default
The value specified by this option will be returned if the desired
pillar key does not exist.
If a default value is not specified, then it will be an empty string,
unless :conf_minion:`pillar_raise_on_missing` is set to ``True``, in
which case an error will be raised.
merge : ``False``
If ``True``, the retrieved values will be merged into the passed
default. When the default and the retrieved value are both
dictionaries, the dictionaries will be recursively merged.
.. versionadded:: 2014.7.0
.. versionchanged:: 2016.3.7,2016.11.4,2017.7.0
If the default and the retrieved value are not of the same type,
then merging will be skipped and the retrieved value will be
returned. Earlier releases raised an error in these cases.
merge_nested_lists
If set to ``False``, lists nested within the retrieved pillar
dictionary will *overwrite* lists in ``default``. If set to ``True``,
nested lists will be *merged* into lists in ``default``. If unspecified
(the default), this option is inherited from the
:conf_minion:`pillar_merge_lists` minion config option.
.. note::
This option is ignored when ``merge`` is set to ``False``.
.. versionadded:: 2016.11.6
delimiter
Specify an alternate delimiter to use when traversing a nested dict.
This is useful for when the desired key contains a colon. See CLI
example below for usage.

pillarenv
If specified, this function will query the master to generate fresh
pillar data on the fly, specifically from the requested pillar
environment. Note that this can produce different pillar data than
executing this function without an environment, as its normal behavior
is just to return a value from minion's pillar data in memory (which
can be sourced from more than one pillar environment).
Using this argument will not affect the pillar data in memory. It will
however be slightly slower and use more resources on the master due to
the need for the master to generate and send the minion fresh pillar
data. This tradeoff in performance however allows for the use case
where pillar data is desired only from a single environment.
