NAME

    Mojolicious::Plugin::PetalTinyRenderer - Petal::Tiny renderer plugin

SYNOPSIS

      # Mojolicious
      $self->plugin('PetalTinyRenderer');
    
      # Mojolicious::Lite
      plugin 'PetalTinyRenderer';

DESCRIPTION

    Mojolicious::Plugin::PetalTinyRenderer is a renderer for templates
    written for Petal::Tiny, which is a Perl implementation of the Template
    Attribute Language (TAL).

OPTIONS

    Mojolicious::Plugin::PetalTinyRenderer supports the following option.

 name

      # Mojolicious::Lite
      plugin PetalTinyRenderer => {name => 'petal'};

    Handler name, defaults to tal.

 encoding

    Encoding of the template-files as supplied to open, defaults to
    :encoding(UTF-8).

STASH

    The stash is directly available in the templates, see the use of foo in
    the example.

 h

    Helpers are available via the h entry in the stash.

     <a tal:attributes="href h/url_for --index" href="/">go back to index</a>

 c

    The current controller instance can be accessed as c.

     I see you are requesting a document from
     <span tal:replace="c/req/headers/host">Lorem ipsum</span>.

USEFUL PATTERNS

    Call helper-function without generating html (-- prefixes a literal
    string):

     <span tal:condition="true:h/layout --default" tal:omit-tag="" />

    Use a temporary variable to hold dynamically generated string for
    helper function:

     <span tal:define="mytitle h/localization --login"
           tal:condition="true:h/title mytitle"
           tal:omit-tag="" />

    Insert styled paragraph with error-message, if any (the structure
    keyword means don't escape returned html):

     <p style="color:red" tal:condition="true:message" tal:content="structure message">
       Error message
     </p>

    Include other action/template:

     <span tal:replace="structure h/include --example/welcome" />

    You can loop over Mojo::Collections:

     <li tal:repeat="key some_mojo_collection" tal:content="key" />

    See Petal::Tiny for more.

    Author's observation: If you need to write very complex TAL-constructs,
    maybe you should reconsider what belongs in the controller and what
    belongs in the template. TAL seems to be very good at exposing this
    anti-pattern.

EXAMPLE

     use Mojolicious::Lite;
    
     plugin 'PetalTinyRenderer';
    
     get '/' => sub {
         my $self = shift;
         $self->stash( foo => Mojo::Collection->new(1,2,3) );
         $self->render('index');
     };
    
     app->start;
    
     __DATA__
