# CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplateExpr(3pm)

HTML::Template::Expr driver to AnyTemplate

## NAME

CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplateExpr - HTML::Template::Expr 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::Expr 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::Expr)

### Syntax

The HTML::Template::Expr syntax for embedding components is:

```
    <TMPL_VAR EXPR="CGIAPP_embed('some_run_mode', param1, param2, 'literal string3')">
```

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       '__ACME_render'
```

Then the embedded component tag will look like:

```
    <TMPL_VAR EXPR="__ACME_render('some_run_mode')">
```

The value of `"embed_tag_name"` must consist of numbers, letters and underscores (`"_"`), and must not begin with a number.

## CONFIGURATION

The CGI::Application::Plugin::AnyTemplate::Driver::HTMLTemplateExpr 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::HTMLTemplateExpr will copy all of the webapp's query params into the template using HTML::Template::Expr's `"associate"` mechanism:

  ```
      my $driver = HTML::Template::Expr->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::Expr.

### required\_modules

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

## DRIVER METHODS

- initialize

  Initializes the `"HTMLTemplateExpr"` driver.  See the docs for CGI::Application::Plugin::AnyTemplate::Base for details.

- render\_template

  Fills the HTML::Template::Expr object with `"$self->param"`, and returns the output (as a string reference).

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