Mojolicious::Renderer - Generate dynamic content
use Mojolicious::Renderer; my $renderer = Mojolicious::Renderer->new; push @{$renderer->classes}, 'MyApp::Controller::Foo'; push @{$renderer->paths}, '/home/sri/templates';
Mojolicious::Renderer is the standard Mojolicious renderer.
See Mojolicious::Guides::Rendering for more.
Mojolicious::Renderer implements the following attributes.
my $cache = $renderer->cache; $renderer = $renderer->cache(Mojo::Cache->new);
Renderer cache, defaults to a Mojo::Cache object.
my $classes = $renderer->classes; $renderer = $renderer->classes(['main']);
Classes to use for finding templates in DATA sections with Mojo::Loader, first one has the highest precedence, defaults to main. Only files with exactly two extensions will be used, like index.html.ep. Note that for templates to be detected, these classes need to have already been loaded and added before "warmup" is called, which usually happens automatically during application startup.
DATA
main
index.html.ep
# Add another class with templates in DATA section push @{$renderer->classes}, 'Mojolicious::Plugin::Fun'; # Add another class with templates in DATA section and higher precedence unshift @{$renderer->classes}, 'Mojolicious::Plugin::MoreFun';
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.
gzip
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.
format
html
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.
inline
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.
UTF-8
my $handlers = $renderer->handlers; $renderer = $renderer->handlers({epl => sub {...}});
Registered handlers.
my $helpers = $renderer->helpers; $renderer = $renderer->helpers({url_for => sub {...}});
Registered helpers.
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.
860
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';
Mojolicious::Renderer inherits all methods from Mojo::Base and implements the following new ones.
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.
GET
POST
Accept
$renderer = $renderer->add_handler(epl => sub {...});
Register a handler.
$renderer->add_handler(foo => sub ($renderer, $c, $output, $options) { ... $$output = 'Hello World!'; });
$renderer = $renderer->add_helper(url_for => sub {...});
Register a helper.
$renderer->add_helper(foo => sub ($c, @args) { ... });
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.
template
variant
handler
undef
my $helper = $renderer->get_helper('url_for');
Get a helper by full name, generate a helper dynamically for a prefix, or return undef if no helper or prefix could be found. Generated helpers return a proxy object containing the current controller object and on which nested helpers can be called.
my ($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.
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.
my $name = $renderer->template_for(Mojolicious::Controller->new);
Return default template name for Mojolicious::Controller object, or undef if no name could be generated.
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.
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.
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.
$renderer->warmup;
Prepare templates from "classes" for future use.
