NAME Dancer2::Template::Caribou - Template::Caribou wrapper for Dancer2 VERSION version 0.2.0 SYNOPSIS # in 'config.yml' template: Caribou engines: template: Caribou: namespace: MyApp::View auto_reload: 1 # and then in the application get '/' => sub { ...; template 'main' => \%options; }; DESCRIPTION "Dancer2::Template::Caribou" is an interface for the Template::Caribou template system. Be forewarned, both this module and "Template::Caribou" itself are alpha-quality software and are still subject to any changes. <Caveat Maxima Emptor>. Basic Usage At the base, if you do get '/' => sub { ... return template 'MyView', \%options; }; the template name (here *MyView*) will be concatenated with the configured view namespace (which defaults to *Dancer2::View*) to generate the Caribou class name. A Caribou object is created using %options as its arguments, and its inner template "page" is then rendered. In other words, the last line of the code above becomes equivalent to return Dancer2::View::MyView->new( %options )->render('page'); '/views' template classes Template classes can be created straight from the "/views" directory. Any directory containing a file named "bou" will be turned into a "Template::Caribou" class. Additionally, any file with a ".bou" extension contained within that directory will be turned into a inner template for that class. The 'bou' file The 'bou' file holds the custom bits of the Template::Caribou class. For example, a basic welcome template could be: # in /views/welcome/bou use Template::Caribou::Tags::HTML ':all'; has name => ( is => 'ro' ); template page => sub { my $self = shift; html { head { title { 'My App' } }; body { h1 { 'hello ' . $self->name .'!' }; }; } }; which would be invoqued via get '/hi/:name' => sub { template 'welcome' => { name => param('name') }; }; The inner template files All files with a '.bou' extension found in the same directory as the 'bou' file become inner templates for the class. So, to continue with the example above, we could change it into # in /views/howdie/bou use Template::Caribou::Tags::HTML ':all'; has name => ( is => 'ro' ); # in /views/howdie/page html { head { title { 'My App' } }; body { h1 { 'howdie ' . $self->name . '!' }; }; } Layouts as roles For the layout sub-directory, an additional piece of magic is performed. The 'bou'-marked directories are turned into roles instead of classes, which will be applied to the template class. Again, to take our example: # in /views/layouts/main/bou # empty file # in /views/layouts/main/page # the import of tags really needs to be here # instead than in the 'bou' file use Template::Caribou::Tags::HTML ':all'; html { head { title { 'My App' } }; body { show( 'inner' ); }; } # in /views/hullo/bou use Template::Caribou::Tags::HTML ':all'; has name => ( is => 'ro' ); # in /views/howdie/inner h1 { 'hullo ' . $self->name . '!' }; CONFIGURATION namespace The namespace under which the Caribou classes are created. defaults to "Dancer2::View". auto_reload If set to "true", the Caribou object will verify if any of the template files have changed before rendering and, if that's the case, will self-update. Defaults to "false". CONVENIENCE ATTRIBUTES AND METHODS Auto-generated templates have the Dancer2::Template::Caribou::DancerVariables role automatically applied to them, which give them helper methods like "uri_for()" and "context()" to interact with the Dancer environment. If you roll out your own template classes, you simply have to apply the role to have access to the same niftiness. package Dancer2::View::MyView; use Moose; use Template::Caribou; with qw/ Template::Caribou Dancer2::Template::Caribou::DancerVariables /; template page => sub { my $self = shift; print ::RAW $self->uri_for( '/foo' ); }; context() The Dancer2::Core::Context object associated with the current request.
