CGI::Application::Plugin::AnyTemplate::Driver::Petal(3) Petal plugin to AnyTemplate

DESCRIPTION

This is a driver for CGI::Application::Plugin::AnyTemplate, which provides the implementation details specific to rendering templates via the Petal templating system.

All "AnyTemplate" drivers are designed to be used the same way. For general usage instructions, see the documentation of CGI::Application::Plugin::AnyTemplate.

EMBEDDED COMPONENT SYNTAX (Petal)

Note that for embedding component to work properly in Petal, you need to enclose the contents of the included file in tags, such as "<span>" tags. 

    <span>
    var: <span petal:replace="var"></span>
    </span>

The "Petal" syntax for embedding components is: 

    <span tal:replace="structure CGIAPP/embed 'some_run_mode' some_param1 some_param2 'some literal string 3'">
        this text gets replaced by the output of some_run_mode
    </span>

This can be overridden by the following configuration variables: 

    embed_tag_name       # default 'CGIAPP'

For instance by setting the following values in your configuration file: 

    embed_tag_name       'MYAPP'

Then the embedded component tag will look like: 

    <span tal:replace="structure MYAPP/embed 'some_run_mode'">
        this text gets replaced by the output of some_run_mode
    </span>

Note that when creating documents to be included as components, they must be complete XML documents.

CONFIGURATION

The CGI::Application::Plugin::AnyTemplate::Driver::Petal driver accepts the following config parameters:
embed_tag_name
The name of the tag used for embedding components. Defaults to "CGIAPP".
template_extension
If "auto_add_template_extension" is true, then CGI::Application::Plugin::AnyTemplate will append the value of "template_extension" to "filename". By default the "template_extension" is ".xhtml".
emulate_associate_query
This feature is now deprecated and will be removed in a future release.

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.

This is similar to what would happen if you used HTML::Template's "associate" feature with the webapp's query object: 

    my $driver = HTML::Template->new(
        associate => $self->query,
    );

By default "emulate_associate_query" is false.

All other configuration parameters are passed on unchanged to Petal.

required_modules

The "required_modules" function returns the modules required for this driver to operate. In this case: "Petal".

DRIVER METHODS

initialize
Initializes the Petal driver. See the docs for CGI::Application::Plugin::AnyTemplate::Base for details.
render_template
Fills the Petal object with "$self->param"

If the param "emulate_associate_query" is true, then set params for each of $self->{'webapp'}->query, mimicking HTML::Template's associate mechanism.

Also set up a CGI::Application::Plugin::AnyTemplate::ComponentHandler object so that the "CGIAPP.embed" callback will work.

Returns the output of the filled template as a string reference.

See the docs for CGI::Application::Plugin::AnyTemplate::Base for details.
