Line Wrap (filter for TWIG)

TWIG filter to wrap lines over a specified length with a newline, or optionally pass in a different separator.

Designed for wrapping iCal files to 75 chars max length, although should be useful in any application requiring line wrapping.

Installation

1. Install through composer.

composer require techwilk/twig-linewrap

2. Then add as an extension to TWIG:

$twig->addExtension(new \TechWilk\Twig\Extension\LineWrap());

Use

Use as a standard twig filter, passing in a maximum length after which to wrap:

{{ 'this is some text that goes on forever' | linewrap(10) }}

outputs:

this is so
me text th
at goes on
 forever

Optionally pass in a different separator (such as for iCal wrapping):

{{ 'this is some text that goes on forever' | linewrap(75, "\n ") }}
