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.
