NAME Template::Flute - Modern HTML Engine VERSION Version 0.0001 SYNOPSIS use Template::Flute; my ($cart, $flute, %values); $cart = [{...},{...}]; $values{cost} = ... $flute = new Template::Flute(specification_file => 'cart.xml', template_file => 'cart.html', iterators => {cart => $cart}, values => \%values, ); print $flute->process(); DESCRIPTION Template::Flute enables you to completely separate web design and programming tasks for dynamic web applications. Templates are plain HTML files without inline code or mini language, thus making it easy to maintain them for web designers and to preview them with a browser. The CSS selectors in the template are tied to your data structures or objects by a specification, which relieves the programmer from changing his code for mere changes of class names. Workflow The easiest way to use Template::Flute is to pass all necessary parameters to the constructor and call the process method to generate the HTML. You can also break it down in separate steps: 1. Parse specification Parse specification based on your specification format (e.g with Template::Flute::Specification::XML or Template::Flute::Specification::Scoped.). $xml_spec = new Template::Flute::Specification::XML; $spec = $xml_spec->parse(q{ }); 2. Parse template Parse template with Template::Flute::HTML object. $template = new Template::Flute::HTML; $template->parse(q{ Cart Example
Name Quantity Price
Sample Book $1
}, $spec); 3. Produce HTML output $zoom = new Template::Zoom(template => $template, iterators => {cart => $cart}, values => {cost => '84.94'}); $zoom->process(); CONSTRUCTOR new Create a Template::Flute object with the following parameters: specification_file Specification file name. specification_parser Select specification parser. This can be either the full class name like MyApp::Specification::Parser or the last part for classes residing in the Template::Flute::Specification namespace. template_file HTML template file. database Template::Flute::Database::Rose object. filters Hash reference of filter functions. i18n Template::Flute::I18N object. values Hash reference of values to be used by the process method. METHODS process [HASHREF] Processes HTML template and returns HTML output. filter FILTER VALUE Runs the filter named FILTER on VALUE and returns the result. value NAME Returns the value for NAME. set_values HASHREF Sets hash reference of values to be used by the process method. Same as passing the hash reference as values argument to the constructor. template Returns HTML template object. SPECIFICATION The specification ties the elements in the HTML template to the data (variables, lists, forms) which is added to the template. The default format for the specification is XML implemented by the Template::Flute::Specification::XML module. You can use the Config::Scoped format implemented by Template::Flute::Specification::Scoped module or write your own specification parser class. Possible elements in the specification are: container This container is only shown in the output if the value billing_address is set: list param value input filter sort i18n ITERATORS Template::Flute uses iterators to retrieve list elements and insert them into the document tree. This abstraction relieves us from worrying about where the data actually comes from. We basically just need an array of hash references and an iterator class with a next and a count method. For your convenience you can create an iterator from Template::Flute::Iterator class very easily.
