format.prepend ViewHelper `<vhs:format.prepend>`
================================================


Format: Prepend string content
==============================

Prepends one string on another. Although this task is very
easily done in standard Fluid - i.e. {add}{subject} - this
ViewHelper makes advanced chained inline processing possible:

::

    <!-- Adds 1H to DateTime, formats using timestamp input which requires prepended @ -->
    {dateTime.timestamp
        -> v:math.sum(b: 3600)
        -> v:format.prepend(add: '@')
        -> v:format.date(format: 'Y-m-d H:i')}
    <!-- You don't have to break the syntax into lines; done here for display only -->
