-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<$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<< $options->{inline} >> is trueish then C<$template> is a string
-containing the template code to interprete.
+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.
-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<< $options->{type} >> can be either C<html>
-or C<js> and defaults to C<html>. An exception will be thrown if that
-file does not exist.
+Other reference types, unknown options and unknown arguments to the
+C<type> option cause the function to L<croak>.
-The template itself has access to the following variables:
+The following options are available:
+
+=over 2
+
+=item C<type>
+
+The template type. Can be C<html> (the default), C<js> for JavaScript,
+C<json> for JSON and C<text> for plain text content. Affects only the
+extension that's added to the file name given with a non-reference
+C<$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<$::locale>
=item * C<LXCONFIG> -- all parameters from C<config/kivitendo.conf>
with the same name they appear in the file (first level is the
-section, second the actual variable, e.g. C<system.dbcharset>,
+section, second the actual variable, e.g. C<system.language>,
C<features.webdav> etc)
=item * C<LXDEBUG> -- C<$::lxdebug>

Example: Render a string and return its content for further processing
by the calling function.
- my $content = $presenter->render(
- '[% USE JavaScript %][% JavaScript.replace_with("#someid", "js/something") %]',
- { type => 'js', inline => 1 }
+ my $content = $presenter->render(\'[% USE JavaScript %][% JavaScript.replace_with("#someid", "js/something") %]');
+
+Example: Return the content of a JSON template file without processing
+it at all:
+
+ my $template_content = $presenter->render(
+ 'customer/contact',
+ { type => 'json', process => 0 }
);
=item C<escape $text>
L<SL::Presenter::EscapedText>. This is a no-op (the same instance will
be returned).
+=item C<escape_js $text>
+
+Returns a JavaScript-escaped version of C<$text>. Instead of a string
+an instance of the thin proxy-object L<SL::Presenter::EscapedText> is
+returned.
+
+It is safe to call C<escape> on an instance of
+L<SL::Presenter::EscapedText>. This is a no-op (the same instance will
+be returned).
+
=item C<get_template>
Returns the global instance of L<Template> and creates it if it
