.TH CGI::Application::Plugin::AnyTemplate::Driver::Petal 3pm "2020-10-26" "perl v5.30.3" "User Contributed Perl Documentation"
.\" For nroff, turn off justification.  Always turn off hyphenation; it makes
.\" way too many mistakes in technical documents.
.if n .ad l
.nh
.SH "NAME"
CGI::Application::Plugin::AnyTemplate::Driver::Petal \- Petal plugin to AnyTemplate
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a driver for CGI::Application::Plugin::AnyTemplate, which
provides the implementation details specific to rendering templates via
the Petal templating system.
.PP
All \f(CW\*(C`AnyTemplate\*(C'\fR drivers are designed to be used the same way.  For
general usage instructions, see the documentation of
CGI::Application::Plugin::AnyTemplate.
.SH "EMBEDDED COMPONENT SYNTAX (Petal)"
.IX Header "EMBEDDED COMPONENT SYNTAX (Petal)"
\&\fBNote that for embedding component to work properly in Petal, you need to enclose\fR
\&\fBthe contents of the included file in tags, such as \f(CB\*(C`<span>\*(C'\fB tags.\fR
.PP
.Vb 3
\&    <span>
\&    var: <span petal:replace="var"></span>
\&    </span>
.Ve
.PP
The \f(CW\*(C`Petal\*(C'\fR syntax for embedding components is:
.PP
.Vb 3
\&    <span tal:replace="structure CGIAPP/embed \*(Aqsome_run_mode\*(Aq some_param1 some_param2 \*(Aqsome literal string 3\*(Aq">
\&        this text gets replaced by the output of some_run_mode
\&    </span>
.Ve
.PP
This can be overridden by the following configuration variables:
.PP
.Vb 1
\&    embed_tag_name       # default \*(AqCGIAPP\*(Aq
.Ve
.PP
For instance by setting the following values in your configuration file:
.PP
.Vb 1
\&    embed_tag_name       \*(AqMYAPP\*(Aq
.Ve
.PP
Then the embedded component tag will look like:
.PP
.Vb 3
\&    <span tal:replace="structure MYAPP/embed \*(Aqsome_run_mode\*(Aq">
\&        this text gets replaced by the output of some_run_mode
\&    </span>
.Ve
.PP
Note that when creating documents to be included as components, they
must be complete \s-1XML\s0 documents.
.SH "CONFIGURATION"
.IX Header "CONFIGURATION"
The CGI::Application::Plugin::AnyTemplate::Driver::Petal driver
accepts the following config parameters:
.IP "embed_tag_name" 4
.IX Item "embed_tag_name"
The name of the tag used for embedding components.  Defaults to
\&\f(CW\*(C`CGIAPP\*(C'\fR.
.IP "template_extension" 4
.IX Item "template_extension"
If \f(CW\*(C`auto_add_template_extension\*(C'\fR is true, then
CGI::Application::Plugin::AnyTemplate will append the value of
\&\f(CW\*(C`template_extension\*(C'\fR to \f(CW\*(C`filename\*(C'\fR.  By default
the \f(CW\*(C`template_extension\*(C'\fR is \f(CW\*(C`.xhtml\*(C'\fR.
.IP "emulate_associate_query" 4
.IX Item "emulate_associate_query"
\&\fBThis feature is now deprecated and will be removed in a future release.\fR
.Sp
If this config parameter is true, then CGI::Application::Plugin::AnyTemplate::Driver::Petal
will copy all of the webapp's query params into the template.
.Sp
This is similar to what would happen if you used HTML::Template's
\&\f(CW\*(C`associate\*(C'\fR feature with the webapp's query object:
.Sp
.Vb 3
\&    my $driver = HTML::Template\->new(
\&        associate => $self\->query,
\&    );
.Ve
.Sp
By default \f(CW\*(C`emulate_associate_query\*(C'\fR is false.
.PP
All other configuration parameters are passed on unchanged to Petal.
.SS "required_modules"
.IX Subsection "required_modules"
The \f(CW\*(C`required_modules\*(C'\fR function returns the modules required for this driver
to operate.  In this case: \f(CW\*(C`Petal\*(C'\fR.
.SH "DRIVER METHODS"
.IX Header "DRIVER METHODS"
.IP "initialize" 4
.IX Item "initialize"
Initializes the Petal driver.  See the docs for
CGI::Application::Plugin::AnyTemplate::Base for details.
.IP "render_template" 4
.IX Item "render_template"
Fills the Petal object with \f(CW\*(C`$self\->param\*(C'\fR
.Sp
If the param \f(CW\*(C`emulate_associate_query\*(C'\fR is true, then set params for each of
\&\f(CW$self\fR\->{'webapp'}\->query, mimicking HTML::Template's associate
mechanism.
.Sp
Also set up a CGI::Application::Plugin::AnyTemplate::ComponentHandler
object so that the \f(CW\*(C`CGIAPP.embed\*(C'\fR callback will work.
.Sp
Returns the output of the filled template as a string reference.
.Sp
See the docs for CGI::Application::Plugin::AnyTemplate::Base for details.
