NAME

Prancer::Plugin::Xslate

SYNOPSIS

This plugin provides access to the Text::Xslate templating engine for your Prancer application and exports a keyword to access the configured engine.

This template plugin supports setting the basic configuration in your Prancer application's configuration file. You can also configure all options at runtime using arguments to render.

To set a configuration in your application's configuration file, begin the configuration block with template and put all options underneath that. For example:

template:
    cache_dir: /path/to/cache
    verbose: 2

Any option for Text::Xslate whose value can be expressed in a configuration file can be put into your application's configuration. Then using the template engine is as simple as this:

use Prancer::Plugin::Xslate qw(render);

Prancer::Plugin::Xslate->load();

print render("foobar.tx", \%vars);

However, there are some configuration options that cannot be expressed in configuration files, especially the functions option. There are two additional ways to handle that. The first way is to pass them to the template plugin when loading it, like this:

Prancer::Plugin::Xslate->load({
    'function' => {
        'encode_json' => sub {
            return JSON::encode_json(@_);
        }
    }
});

The second way is to the optional third argument to render, like this:

print render("foobar.tx", \%vars, {
    'function' => {
        'md5_hex' => sub {
            return Digest::MD5::md5_hex(@_);
        }
    }
});

Options passed when initializing the template plugin will override options configured in the configuration file. Options passed when calling render will override options passed when initializing the template plugin. This is the way you might go about adding support for functions and methods.

METHODS

path

This will set the path option for Text::Xslate to anything that Text::Xslate suports. Each call to this method will overwrite whatever the previous template path was. For example:

# sets template path to just /path/to/templates
$plugin->path('/path/to/templates');

# blows away /path/to/templates set previously and sets it to this arrayref
$plugin->path([ '/path/to/global-templates', '/path/to/local-templates' ]);

# blows away the arrayref set previously and sets it to this hashref
$plugin->path({
    'foo.tx' => '<html><body><: $foo :><br/></body></html>',
    'bar.tx' => 'Hello, <: $bar :>.',
});
mark_raw, unmark_raw, html_escape, uri_escape

Proxies access to the static functions of the same name provided in Text::Xslate. These can all be called statically or an instance of the plugin and all will work just fine. All of these can also be exported on demand. For more information on how to use these functions, read the Text::Xslate documentation.
