A systems integration framework, built to bring the benefits of configuration management to your entire infrastructure.

Chef::Mixin::Template::TemplateContext#render

Takes the name of the partial, plus a hash of options. Returns a
string that contains the result of the evaluation of the partial.

All variables from the parent template will be propagated down to
the partial, unless you pass the +variables+ option (see below).

Valid options are:

:local:: If true then the partial name will be interpreted as the
         path to a file on the local filesystem; if false (the
         default) it will be looked up in the cookbook according to
         the normal rules for templates.
:source:: If specified then the partial will be looked up with this
          name or path (according to the +local+ option) instead of
          +partial_name+.
:cookbook:: Search for the partial in the provided cookbook instead
            of the cookbook that contains the top-level template.
:variables:: A Hash of variable_name => value that will be made
             available to the partial. If specified, none of the
             variables from the master template will be, so if you
             need them you will need to propagate them explicitly.
