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';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.
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.
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 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 handler.
$renderer->add_handler(foo => sub {
my ($renderer, $c, $output, $options) = @_;
...
$$output = 'Hello World!';
});add_helper
$renderer = $renderer->add_helper(url_for => sub {...});Register a helper.
$renderer->add_helper(foo => sub {
my ($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, {
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);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.
