TwigExt - Mercator Twig Extensions
TwigExt provides a set of Twig filters and functions for WinterCMS. In addition, it allows developers to easily add new Twig functions and filters to a WinterCMS theme.
The plugin is based on OctoberCMS' Twig Extensions by Vojta Svoboda and includes that functionality. It has been tested with WinterCMS 1.1.7.
Installation
Use Composer to install the plugin by executing
from the root of your WinterCMS installation.
Alternatively, create a directory "mercator/twigext", download the files from Github and move them in the newly created sub-directory.
Installation from the WinterCMS backend will be added once the WinterCMS marketplace is available.
You can now use the newly added filters and functions in your theme (layouts, partials, ....). For example:
or
or
Available functions
QR Code
QR code for inline use (qrcodeSRC and qrcodeIMG)
Create a GIF with a red QR code on a transparent background pointing to mercator.li:
alternatively, use the short version
to produce the full image tag, i.e.
In this case, alt will be the same as the actual QR code content.
You can create all different sorts of QR codes, e.g. a vcard:
Parameters for the above functions are:
- text: Text to be converted to a QR code, e.g. https://mercator.li. Defaults to "no data here".
- scale: Scale factor of the QR code, 1 being the smallest. Defaults to 2.
- background: Background color in RGB hex format. Set to XXXXXX to generate a transparent background. Defaults to XXXXXX, which is transparent.
- foreground: Foreground color in RGB hex format. Defaults to 000000, which is black.
- ecc: Error correction level, valid values: qr, qr-l, qr-m, qr-q, qr-h. Defaults to qr-l.

The example above will output a string like 4 seconds ago or in 1 month, depending on the filtered date.
Output is translatable. All translations are stored at /lang
folder in this plugin. If you want more locales, just copy them from this repository, replace %count%
with :count
and send it as pull reqest to this repository.
Arguments
- date: The date for calculate the difference from now. Can be a string or a DateTime instance.
- now: The date that should be used as now. Can be a string or a DateTime instance. Do not set this argument to use current date.

- 'percent': NumberFormatter::PERCENT

localizedcurrency
Use the localizedcurrency filter to format a currency value into a localized string. Note that php5-intl extension has to be installed!
Arguments

- locale: The locale used for the format. If NULL is given, Twig will use Locale::getDefault()
mailto
Filter for rendering email as normal mailto link, but with encryption against bots!
returns something along the lines
which will be rendered to page as normal
PHP encrypts your email address and generates the JavaScript that decrypts it. Most bots can't execute JavaScript and that is what makes this work. A visitors of your web page will not notice that you used this script as long as they has JavaScript enabled. The visitors will see "[javascript protected email address]" instead of the email address if they has JavaScript disabled.
Filter parameters
- first boolean parameter = returns email clickable (with link)
- second boolean parameter = encryption is enabled
- third string parameter = link text (not encrypted!)
- fourth (optional) parameter = CSS class name (will render <a mailto:.. class="my-class">..)
var_dump
Dumps information about a variable.
revision
Force the browser to reload cached modified/updated asset files. You can provide a format parameter so that the prepended timestamp get converted accordingly to the PHP date() function.
will return something like
sortbyfield
Sort array/collection by given field (key).
Output will be: John David
Adding New Filters and Functions
Often, a project requires a few specific functions. These can be added by adding twig/functions or twig/filters subdirectories to the current theme and include functions an filters in there. TwigExt will load all files startung with an underscore _ and ending in .php and make the included filters and functions available in Twig.
Functions are added as follow (by placing them, e.g, in twig/functions/_myFucntions.php in the active themes directory):
Filters are added as follow (by placing them, e.g, in twig/filters/_myFucntions.php in the active themes directory):
Filters and functions MUST provide return values. Multiple new filters or functions can be added to the respective arrays in one go. See Winter's documenttation for additional details.
