NAME

Mojolicious::Renderer - Generate dynamic content

SYNOPSIS

  use Mojolicious::Renderer;

  my $renderer = Mojolicious::Renderer->new;
  push @{$renderer->classes}, 'MyApp::Controller::Foo';
  push @{$renderer->paths}, '/home/sri/templates';

DESCRIPTION

Mojolicious::Renderer is the standard Mojolicious renderer.

See Mojolicious::Guides::Rendering for more.

ATTRIBUTES

Mojolicious::Renderer implements the following attributes.

cache

  my $cache = $renderer->cache;
  $renderer = $renderer->cache(Mojo::Cache->new);

Renderer cache, defaults to a Mojo::Cache object.

classes

  my $classes = $renderer->classes;
  $renderer   = $renderer->classes(['main']);

Classes to use for finding templates in DATA sections, first one has the highest precedence, defaults to main.

  # Add another class with templates in DATA section
  push @{$renderer->classes}, 'Mojolicious::Plugin::Fun';

default_format

  my $default = $renderer->default_format;
  $renderer   = $renderer->default_format('html');

The default format to render if format is not set in the stash.

default_handler

  my $default = $renderer->default_handler;
  $renderer   = $renderer->default_handler('ep');

The default template handler to use for rendering in cases where auto detection doesn't work, like for inline templates.

encoding

  my $encoding = $renderer->encoding;
  $renderer    = $renderer->encoding('koi8-r');

Will encode generated content if set, defaults to UTF-8. Note that many renderers such as Mojolicious::Plugin::EPRenderer also use this value to determine if template files should be decoded before processing.

handlers

  my $handlers = $renderer->handlers;
  $renderer    = $renderer->handlers({epl => sub {...}});

Registered handlers, by default only data, text and json are already defined.

helpers

  my $helpers = $renderer->helpers;
  $renderer   = $renderer->helpers({url_for => sub {...}});

Registered helpers.

paths

  my $paths = $renderer->paths;
  $renderer = $renderer->paths(['/home/sri/templates']);

Directories to look for templates in, first one has the highest precedence.

  # Add another "templates" directory
  push @{$renderer->paths}, '/home/sri/templates';

METHODS

Mojolicious::Renderer inherits all methods from Mojo::Base and implements the following new ones.

accepts

  my $all  = $renderer->accepts(Mojolicious::Controller->new);
  my $best = $renderer->accepts(Mojolicious::Controller->new, 'html', 'json');

Select best possible representation for Mojolicious::Controller object from Accept request header, format stash value or format GET/POST parameter, defaults to returning the first extension if no preference could be detected. Since browsers often don't really know what they actually want, unspecific Accept request headers with more than one MIME type will be ignored, unless the X-Requested-With header is set to the value XMLHttpRequest.

add_handler

  $renderer = $renderer->add_handler(epl => sub {...});

Register a new handler.

add_helper

  $renderer = $renderer->add_helper(url_for => sub {...});

Register a new helper.

get_data_template

  my $template = $renderer->get_data_template({
    template       => 'foo/bar',
    format         => 'html',
    handler        => 'epl'
  });

Get a DATA section template by name, usually used by handlers.

get_helper

  my $helper = $renderer->get_helper('url_for');

Get a helper by full name, generate a helper dynamically for a prefix or return undef if no helper or prefix could be found. Generated helpers return a proxy object containing the current controller object and on which nested helpers can be called.

render

  my ($output, $format) = $renderer->render(Mojolicious::Controller->new, {
    template => 'foo/bar',
    foo      => 'bar'
  });

Render output through one of the renderers. See "render" in Mojolicious::Controller for a more user-friendly interface.

template_for

  my $name = $renderer->template_for(Mojolicious::Controller->new);

Generate default template name for Mojolicious::Controller object.

template_handler

  my $handler = $renderer->template_handler({
    template => 'foo/bar',
    format   => 'html'
  });

Detect handler based on an options hash reference with template and format.

template_name

  my $template = $renderer->template_name({
    template => 'foo/bar',
    format   => 'html',
    handler  => 'epl'
  });

Builds a template name based on an options hash reference with template, format and handler, usually used by handlers.

template_path

  my $path = $renderer->template_path({
    template => 'foo/bar',
    format   => 'html',
    handler  => 'epl'
  });

Builds a full template path based on an options hash reference with template, format and handler, usually used by handlers.
