all of the parameters for controlling the output that the controller's
function does.
-What is rendered and how C<$template> is interpreted is determined by
-the options I<type> and I<inline>.
+What is rendered and how C<$template> is interpreted is determined
+both by C<$template>'s reference type and by the supplied options.
+
+If C<$template> is a normal scalar (not a reference) then it is meant
+to be a template file name relative to the C<templates/webpages>
+directory. The file name to use is determined by the C<type> option.
-If C<< $options->{inline} >> is trueish then C<$template> is a string
-containing the template code to interprete.
+If C<$template> is a reference to a scalar then the referenced
+scalar's content is used as the content to process. The C<type> option
+is not considered in this case.
-If C<< $options->{inline} >> is falsish then C<$template> is
-interpreted as the name of a template file. It is prefixed with
-"templates/webpages/" and postfixed with a file extension based on
-C<< $options->{type} >>. C<< $options->{type} >> can be either C<html>
-or C<js> and defaults to C<html>. An exception will be thrown if that
-file does not exist.
+C<$template> can also be an instance of L<SL::Presenter::EscapedText>
+or a reference to such an instance. Both of these cases are handled
+the same way as if C<$template> were a reference to a scalar: its
+content is processed, and C<type> is not considered.
-The template itself has access to the following variables:
+Other reference types, unknown options and unknown arguments to the
+C<type> option cause the function to L<croak>.
+
+The following options are available:
+
+=over 2
+
+=item C<type>
+
+The template type. Can be C<html> (the default), C<js> for JavaScript,
+C<json> for JSON and C<text> for plain text content. Affects only the
+extension that's added to the file name given with a non-reference
+C<$template> argument.
+
+=item C<process>
+
+If trueish (which is also the default) it causes the template/content
+to be processed by the Template toolkit. Otherwise the
+template/content is returned as-is.
+
+=back
+
+If template processing is requested then the template has access to
+the following variables:
=over 2
=item * C<AUTH> -- C<$::auth>
+=item * C<FLASH> -- the flash instance (C<$::form-E<gt>{FLASH}>)
+
=item * C<FORM> -- C<$::form>
+=item * C<INSTANCE_CONF> -- C<$::instance_conf>
+
=item * C<LOCALE> -- C<$::locale>
=item * C<LXCONFIG> -- all parameters from C<config/kivitendo.conf>
with the same name they appear in the file (first level is the

Example: Render a string and return its content for further processing
by the calling function.

-
-=item C<escape $text>
+ my $content = $presenter->render(\'[% USE JavaScript %][% JavaScript.replace_with("#someid", "js/something") %]');
-Returns an HTML-escaped version of C<$text>. Instead of a string an
-instance of the thin proxy-object L<SL::Presenter::EscapedText> is
-returned.
+Example: Return the content of a JSON template file without processing
+it at all:

-L<SL::Presenter::EscapedText>. This is a no-op (the same instance will
-be returned).
-
-=item C<escaped_text $text>
-
-Returns an instance of L<SL::Presenter::EscapedText>. C<$text> is
-assumed to be a string that has already been HTML-escaped.
-
-It is safe to call C<escaped_text> on an instance of
-L<SL::Presenter::EscapedText>. This is a no-op (the same instance will
-be returned).
