CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplate - HTML::Template

CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplate(3pm) User Contributed Perl Documentation CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplate(3pm)

NAME

CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplate - HTML::Template driver to AnyTemplate

DESCRIPTION

This is a driver for CGI::Application::Plugin::AnyTemplate, which provides the implementation details specific to rendering templates via the HTML::Template 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 (HTML::Template)

Syntax

The HTML::Template syntax for embedding components is:
    <TMPL_VAR NAME="cgiapp_embed('some_run_mode', param1, param2, 'literal string3')">
(Support for parameter passing is limited. See the note on parameters below.)
This can be overridden by the following configuration variables:
    embed_tag_name       # default 'cgiapp_embed'
For instance by setting the following value in your configuration file:
    embed_tag_name       '***component***'
Then the embedded component tag will look like:
    <TMPL_VAR NAME="***component***('some_run_mode')">

Parameters

Since HTML::Template doesn't support parameter passing in the template, the "HTMLTemplate" driver emulates this behaviour.
The parameter list passed to the embed subroutine is parsed before the template is parsed. Literal strings (strings enclosed in single or double quotes) are passed verbatim to the target run mode. Params not enclosed in quotes are looked up in "$self->param"; the resulting literal or looked up values are passed to the target run mode. Finally, the return value of the run mode (its output) is passed as a parameter value to the template.
Note that the param lookup scheme is somewhat simplistic. For instance, it does not respect the scope of loops or conditional constructs within the template.
For proper parameter handling using HTML::Template-style templates, use either the CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplateExpr or the CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplatePluggable driver instead.

CONFIGURATION

The CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplate driver accepts the following config parameters:
embed_tag_name
The name of the tag used for embedding components. Defaults to "cgiapp_embed".
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 ".html".
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::HTMLTemplate will copy all of the webapp's query params into the template using HTML::Template's "associate" mechanism:
 
    my $driver = HTML::Template->new(
        associate => $self->query,
    );
    
 
By default "associate_query" is false.
 
If you provide an "associate" config parameter of your own, that will disable the "associate_query" functionality.
All other configuration parameters are passed on unchanged to HTML::Template.

required_modules

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

DRIVER METHODS

initialize
Initializes the "HTMLTemplate" driver. See the docs for "CGI::Application::Plugin::AnyTemplate::Base" for details.
render_template
Fills the "HTML::Template" object with "$self->param" replacing any magic "*embed*" tags with the content generated by the appropriate runmodes.
 
Returns the output of the filled template as a string reference.
 
See the docs for "CGI::Application::Plugin::AnyTemplate::Base" for details.
