TEMPLATE PROCESSING
As stated in the paper, one only needs four template constructs: data interpolation, conditional template inclusion based upon presence/absence of an boolean data, recursive template references, and most importantly, template application to a multi-valued data.
In addition to that, Plift also provides a mechanism to remove template elements based upon presence/absence of a boolean data. Any other custom processing must be implemented via a "CUSTOM HANDLER".
DATA INTERPOLATION
Almost any type of data can be made available to the template via "Plift::Context/set". Plift will try to render the best string representation for the each type of data. Templates can reference data via the special HTML attribute data-render="foo" or HTML element <render data="foo">.
Consider the following data:
$tempalte->set(
name => 'Carlos Fernando',
now => DateTime->now,
is_admin => 1,
cart => {
total => 500,
items => [
{ name => 'Item 01', price => 100, quantity => 1 },
{ name => 'Item 02', price => 200, quantity => 2 },
]
}
);when consumed by this template:
<div>
Checkout page for <render data="name">Jhon Doe</render>,
rendered at <render data="now" format="%F %T">2016-06-30 14:55:43</render>
<br/>
Total Price: <b data-render="cart.total">100.0</b>
</div>
<table>
<tr><td>Name</td><td>Quantity</td><td>Unit Price</td></tr>
<tr data-render="cart.items">
<td data-render="name">item 1</td>
<td data-render="quantity">2</td>
<td data-render="price" format="currency">R$200</td>
</tr>
</table>produces:
<div>
Checkout page for Carlos Fernando,
rendered at 2016-06-30 16:49:23
<br/>
Total Price: R$500
</div>
<table>
<tr><td>Name</td><td>Quantity</td><td>Unit Price</td></tr>
<tr>
<td>Item 01</td>
<td>R$100</td>
<td>1</td>
</tr>
<tr>
<td>Item 02</td>
<td>R$200</td>
<td>2</td>
</tr>
</table>
