HTL Literals: Booleans, Numbers, Strings and Arrays

A literal holds a constant (fixed) value. HTL has four kinds.

Boolean

Represents an on/off condition.

${true} ${false}

Numbers

HTL supports only positive integers — no negative or floating-point numbers.

${11}

Strings

Hold text values.

${'mytext1'} ${"mytext2"}

<p>${'John\'s car is "awesome !", Maria said'}</p>

These escape sequences are allowed in HTL strings:

Arrays

An array is an ordered, indexed collection of values under one name.

<!--/* element at index 2 */-->
${utilityArray[2]}

<!--/* an array of 5 numbers */-->
${[1,2,3,4,5]}

<!--/* print an array's names separated by ':' */-->
${utilityArray.names @ join=':'}

<!--/* access an array dynamically */-->
<ul data-sly-list="${utilityArray.names}">
    <li>${properties[item]}</li>
</ul>
