README

wp_enqueue_less provides a function to enqueue less stylesheets in WordPress.

Install

Composer

Composer is the best way to install wp_enqueue_less, so you get updates in the future easily.

composer require ed-itsolutions/wp_enqueue_less

and then in your functions.php or plugin.php

require_once('vendor/autoload.php');

Manually

Download a copy of wp_enqueue_less.php and require it in your theme/plugin.

Usage

In your normal wp_enqueue_scripts action simply call wp_enqueue_less

wp_enqueue_less takes 3 arguments.

• key - The key name to use for this stylesheet.
• filePath - The on-disk path to the .less file.
• variables - A key->value array of variables to be passed to the less compiler.

add_action('wp_enqueue_scripts', function(){
  wp_enqueue_style('theme-stylesheet', get_stylesheet_uri());

  wp_enqueue_less('theme-main', get_template_directory() . '/less/main.less', array(
    'main-color' => '#99bbff' // becomes @main-color in your less stylesheet.
  ));
});

Thats it!

wp_enqueue_less will:

• Compile this less file and write the output to /wp-content/uploads/less/key-hash.css (this can be changed with the filter wp_enqueue_less_css_dir).
• Record the current hashes of all the less files used and the variables into the database.
• On the next call if none of the hashes have changed it will skip parsing.
• On a daily basis it will clean out its directory of everything but the current hash version of the stylesheet.
