Less.php module for SilverStripe

A wrapper for less.php to integrate LESS into SilverStripe.

Features

• Integrates a fork of less.php seemessly into SilverStripe
• Includes flushing option (?flush) to regenerate CSS stylesheets (ie. force undetected less changes with @import)
• Writes processed *.css files into assets/_css and automatically modifies Requirements paths
• Allows custom global variables to be passed through to less compiling (yaml configuration)
• Automatic image & @import URL translation (eg: url('../image.png') will get rewritten as url('/path/to/image.png') depending on your website's root folder)
• Automatic compression of CSS files when in Live mode (may require an initial ?flush)
• Adds any processed editor.less files to TinyMCE (must be included in your front-end template)

Requirements

• SilverStripe 4

For SilverStripe 3, please refer to the SilverStripe3 branch.

Installation

composer require axllent/silverstripe-less

Usage

You need refer to your less files by their full LESS filenames (eg:stylesheet.less).

Example

<?php
use SilverStripe\CMS\Controllers\ContentController;
use SilverStripe\View\Requirements;

class PageController extends ContentController
{
    public function init()
    {
        parent::init();
        Requirements:css('resources/themes/site/css/stylesheet.less');
    }
}

The generated HTML will point automatically to the processed CSS file in assets/_css
rather than the original less file location, for example

<link rel="stylesheet" type="text/css"  href="/assets/_css/themes-site-css-stylesheet.css?m=123456789" />
