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 with
       Mojo::Loader, first one has the highest precedence, defaults to "main".
       Only files with exactly two extensions will be used, like
       "index.html.ep". Note that for templates to be detected, these classes
       need to have already been loaded and added before "warmup" is called,
       which usually happens automatically during application startup.

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

         # Add another class with templates in DATA section and higher precedence
         unshift @{$renderer->classes}, 'Mojolicious::Plugin::MoreFun';

   compress
         my $bool  = $renderer->compress;
         $renderer = $renderer->compress($bool);

       Try to negotiate compression for dynamically generated response content
       and "gzip" compress it automatically, defaults to true.

   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,
       defaults to "html". Note that changing the default away from "html" is
       not recommended, as it has the potential to break, for example, plugins
       with bundled templates.

   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.

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

       Registered helpers.

   min_compress_size
         my $size  = $renderer->min_compress_size;
         $renderer = $renderer->min_compress_size(1024);

       Minimum output size in bytes required for compression to be used if
       enabled, defaults to 860.

   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';

         # Add another "templates" directory with higher precedence
         unshift @{$renderer->paths}, '/home/sri/themes/blue/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 "format" "GET"/"POST" parameter, "format" stash value, or "Accept"
       request header, defaults to returning the first extension if no
       preference could be detected.

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

       Register a handler.

         $renderer->add_handler(foo => sub ($renderer, $c, $output, $options) {
           ...
           $$output = 'Hello World!';
         });

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

       Register a helper.

         $renderer->add_helper(foo => sub ($c, @args) {
           ...
         });

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

       Return a "DATA" section template from "classes" for an options hash
       reference with "template", "format", "variant" and "handler" values, or
       "undef" if no template could be found, 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);

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

   respond
         my $bool = $renderer->respond(Mojolicious::Controller->new, $output, $format);
         my $bool = $renderer->respond(
           Mojolicious::Controller->new, $output, $format, $status);

       Finalize dynamically generated response content and "compress" it if
       possible.

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

       Return default template name for Mojolicious::Controller object, or
       "undef" if no name could be generated.

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

       Return handler for an options hash reference with "template", "format"
       and "variant" values, or "undef" if no handler could be found.

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

       Return a template name for an options hash reference with "template",
       "format", "variant" and "handler" values, or "undef" if no template
       could be found, usually used by handlers.

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

       Return the full template path for an options hash reference with
       "template", "format", "variant" and "handler" values, or "undef" if the
       file does not exist in "paths", usually used by handlers.

   warmup
         $renderer->warmup;

       Prepare templates from "classes" for future use.
