    This is the Catalyst view class for the Tenjin template engine.

    Your application should define a view class which is a subclass of this
    module. There is no helper script to create this class automatically,
    but you can do so easily as described in the synopsis.

    Once you've created the view class, you can modify your action handlers
    in the main application and/or controllers to forward to your view
    class. You might choose to do this in the end() method, for example, to
    automatically forward all actions to the Tenjin view class.

            # In MyApp or MyApp::Controller::SomeController

            sub end : Private {
                    my( $self, $c ) = @_;

    This module is now Moose-based, so you can use method modifiers. For
    example, you can perform some operation after or before this module
    begins processing the request or rendering the template.

  COMPONENT( $c, $arguments )
    This method is automatically called by Catalyst when creating the view.
    The method creates an instance of Tenjin using the configuration options
    set in the view.

    Renders the template specified in "$c->stash->{template}" or
    "$c->action" (the private name of the matched action, with the default
    extension specified by the "TEMPLATE_EXTENSION" configuration item.
    Calls render to perform actual rendering. Output is stored in

  check_tmpl( $template_name )
    Checks if a template named $template_name was already registered with
    the view. Returns 1 if yes, "undef" if no.

  register( $tmpl_name, $tmpl_content )
    Registers a template with the view from an arbitrary source, for
    immediate usage in the application. $tmpl_name is the name of the
    template, used to distinguish it from others. $tmpl_content is the body
    of the template. Templates are registered in memory, so don't expect
    them to remain registered between application restarts.

  render( $c, $template, \%args )
    Renders the given template and returns output, or throws an exception if
    an error was encountered.

    $template is the name of the template you wish to render. If this
    template was not registered with the view yet, it will be searched for
    in the directories set in the "INCLUDE_PATH" configuration item.

    The template variables are set to %$args if $args is a hashref, or
    "%{$c->stash}" otherwise. In either case the variables are augmented
    with $base set to "$c->req->base", $name to "$c->config->{name}" and the
    Catalyst context, which will be set to $c unless the "CATALYST_VAR"
    configuration item is set to a different name. If so, the $c, $base and
    $name variables are omitted.

  template_vars( $c )
    Returns a list of key-value pairs to be used as the context variables
    (i.e. the context object) in the Tenjin templates.

  _coerce_paths( $dlim )
    To configure your view class, you can call the "config()" method in the
    view subclass. This happens when the module is first loaded.

            package MyApp::View::Tenjin;

            use strict;
            use base 'Catalyst::View::Tenjin';

                    USE_STRICT => 1,
                    INCLUDE_PATH => [ MyApp->path_to('root', 'templates') ],
                    TEMPLATE_EXTENSION => '.html',
                    ENCODING => 'utf8',

    You can also define a class item in your main application configuration,
    again by calling the uniquitous "config()" method. The items in the
    class hash are added to those already defined by the above two methods.
    This happens in the base class new() method (which is one reason why you
    must remember to call it via "MRO::Compat" if you redefine the "new()"
    method in a subclass).

            package MyApp;

            use strict;
            use Catalyst;

                    name     => 'MyApp',
                    root     => MyApp->path_to('root'),
                    'View::Tenjin' => {
                            USE_STRICT => 1,
                            INCLUDE_PATH => [ MyApp->path_to('root', 'templates') ],
                            TEMPLATE_EXTENSION => '.html',
                            ENCODING => 'utf8',

    The "USE_STRICT" configuration option determines if Tenjin will "use
    strict" when evaluating the embedded Perl code inside your templates. If
    "USE_STRICT" is set to a true value (1), strict will be used. This is
    recommended, but if you're having trouble using "strict", you can set it
    to 0, or just not set it at all (by default, Tenjin will not "use
    strict" on embedded Perl code).

    The "ENCODING" configuration option tells Tenjin that how your template
    files are encoded. By default, Tenjin will try to decode your templates
    as utf8.

    If you set "TEMPLATE_EXTENSION", this extension will be automatically
    appended to "<$c-"stash->{template}>> before being searched in the

    Sometimes it is desirable to modify INCLUDE_PATH for your templates at
    run time.

    Additional paths can be added to the start of INCLUDE_PATH via the stash
    as follows:

            $c->stash->{additional_template_paths} =
                    [$c->config->{root} . '/test_include_path'];

    If you need to add paths to the end of INCLUDE_PATH, there is also an
    include_path() accessor available:

            push( @{ $c->view('Tenjin')->include_path }, qw/path/ );

    Note that if you use include_path() to add extra paths to INCLUDE_PATH,
    you MUST check for duplicate paths. Without such checking, the above
    code will add "path" to INCLUDE_PATH at every request, causing a memory

    A safer approach is to use include_path() to overwrite the array of
    paths rather than adding to it. This eliminates both the need to perform
    duplicate checking and the chance of a memory leak:

            @{ $c->view('Tenjin')->include_path } = qw/path another_path/;

    If you are calling "render" directly then you can specify dynamic paths
    by having a "additional_template_paths" key with a value of additonal
    directories to search. See "CAPTURING TEMPLATE OUTPUT" for an example
    showing this.

    The view plugin renders the template specified in the "template" item in
    the stash.

            sub message : Global {
                    my ($self, $c) = @_;

                    $c->stash->{template} = 'message.html';

    If a stash item isn't defined, then it instead uses the stringification
    of the action dispatched to (as defined by $c->action) in the above
    example, this would be "message", but because the default is to append
    '.html', it would load "root/message.html".

    The items defined in the stash are passed to Tenjin for use as template

            sub default : Private {
                    my ($self, $c) = @_;

                    $c->stash->{template} = 'message.html';
                    $c->stash->{message}  = 'Hello World!';

    A number of other template variables are also added:

            $c      A reference to the context object, $c
            $base   The URL base, from $c->req->base()
            $name   The application name, from $c->config->{name}

    These can be accessed from the template in the usual way:

            # message.html
            The message is: [== $message =]
            The base is [== $base =]
            The name is [== $name =]

    The output generated by the template is stored in "$c->response->body".

    Catalyst::View::Tenjin adds an easy method for providing your own
    templates, such that you do not have to use template files stored on the
    file system. For example, you can use templates stored on a DBIx::Class
    schema. This is similar to Template Toolkit's provider modules, which
    for some reason I never managed to get working. You can register
    templates with your application, and use them on the fly. For example:

            # check if the template was already registered
            unless ($c->view('Tenjin')->check_tmpl($template_name)) {
                    # Load the template
                    my $tmpl = $c->model('DB::Templates')->find($template_name);
                    $c->view('Tenjin')->register($template_name, $tmpl->content);

    If you wish to use the output of a template for some other purpose than
    displaying in the response, you can use the render method. For example,
    use can use it with Catalyst::Plugin::Email:

            sub send_email : Local {
                    my ($self, $c) = @_;

                            header => [
                                    To      => 'me@localhost',
                                    Subject => 'A TT Email',
                            body => $c->view('Tenjin')->render($c, 'email.html', {
                                    additional_template_paths => [ $c->config->{root} . '/email_templates'],
                                    email_tmpl_param1 => 'foo'
                    # Redirect or display a message
