This function provides a simple wrapper around
Puppet::Parser::Functions.function for access within Puppet manifests.
This will allow users to check whether or not a plugin or functionality
such as hiera is installed on the server.

The function only uses the first argument, so raise an error with
too few arguments *and* with too many arguments.

This reverts commit f7a18189ec338b01b0fc89d75def832753af3868, reversing
changes made to 36a7b29630a4d4de17af79b5dd4e9491ec20b123.
I'm reverting this change because of concerns raised by Peter Meier that
it duplicates the "in" operator in the DSL. The "in" operator is new
information that I did not posses when I made the decision to merge.
Because of this new information I'm un-merging and continuing the
discussion in the comments of
https://projects.puppetlabs.com/issues/19272
Reference: GH-130

It is exceptionally difficult to determine if an array contains an element matching a specific value without an iteration or loop construct.
This function is the Puppet equivalent of Array.includes?(foo) in Ruby. The implementation is a verbatim copy of has_key() with the minor modifications needed to support arrays instead of hashes.

Without this patch applied there is no easy way to append one array to
another. This is a problem because it is often desirable to join two
arrays without flattening the contents into a single, one dimensional
array.
This patch addresses the problem by adding a `concat()` function which
takes two arguments. The arguments will be concatenated together and a
new array returned to the caller.

This patch addresses the problem by explicitly returning an empty string if the
string itself is empty. This avoids trying to convert an empty string to a
symbol which is the root cause of the problem.

As far as i know there's no other puppet-dsl-like way to get parameter of
defined resource, so that's why i implemented getparam function, which takes
resource reference and parameter name and returns parameter value.
Here's another example why this function is really useful:
define config($path, $config_param1, $config_param2) { }
define example_resource($config) {
$path = getparam($config, "path")
notice("Path is $path")
}
define example_resource2($example_resource, $config = getparam($example_resource, "config")) {
$config_param1 = getparam($config, "config_param1")
notice("Config parameter is $config_param1")
}
define example_resource3($example_resource, $config = getparam($example_resource, "config")) {
$config_param2 = getparam($config, "config_param2")
notice("Config parameter is $config_param2")
}
class test_getparam {
config { "config_instance":
path => "/some/config/path",
config_param1 => "someconfigtext1",
config_param2 => "someconfigtext2",
}
example_resource { "example_resource_instance":
config => Config["config_instance"]
}
example_resource2 { "example_resource_instance":
example_resource => Example_resource["example_resource_instance"]
}
example_resource3 { "example_resource_instance":
example_resource => Example_resource2["example_resource_instance"]
}
}
class { "test_getparam": }

Its often the case that modules need to install a handful of packages.
In some cases its worth breaking these dependencies out into their own
modules (e.g., Java). In others it makes more sense to keep them in the
module. This can be problematic when multiple modules depend on common
packages (git, python ruby, etc). ensure_resource was a good first step
towards solving this problem. ensure_resource does not handle arrays and
for 3 or more packages stamping out ensure_resource declarations is
tedious.
ensure_packages is a convenience function that takes an array of packages
and wraps calls to ensure_resource. Currently users cannot specify
package versions. But the function could be extended to use a hash if
that functionality would be useful.

If we manage a file we edit with file_line, it should be autorequired by
file_line. Without this patch applied the relationship is not
automatically setup and the user is forced to manually manage the
relationship.
