Grav Prism Highlighter Simpler Plugin

Prism Highlighter Simpler is a Grav plugin that adds simple and powerful code highlighting functionality utilizing the Prism.js syntax highlighter.

It is mainly based on the Prism Highlighter plugin by Trilby Media.

But it doesn't need you to use shortcodes to include your code samples! You just have to use the usual Markdown syntax:

```bash
$ echo $USER

Installation

Manual Installation

To install this plugin, just download the zip version of this repository and unzip it under /your/site/grav/user/plugins. Then, rename the folder to prism-highlight-simpler.

You should now have all the plugin files under

/your/site/grav/user/plugins/prism-highlight-simpler

Languages included

Prism.js supports currently 210 languages, at the time of this edit, and they are all included in this plugin.

Plugins Included

This build of Prism also includes the following plugins:

• Line Highlight
• Toolbar
• Copy to Clipboard

Basic Usage

In your markdown, you can create a block of code, and assign the language to it. You can choose between the list above.

Example using regular markdown fenced code syntax:

  ```php
  <?php
  
  namespace Grav\Plugin;
  
  use \Grav\Common\Plugin;
  use \Grav\Common\Grav;
  use \Grav\Common\Page\Page;
  
  class PrismHighlightSimplerPlugin extends Plugin
  {
      /**
       * @return array
       */
      public static function getSubscribedEvents()
      {
          return [
              'onPageInitialized' => ['onPageInitialized', 0],
              'onShortcodeHandlers' => ['onShortcodeHandlers', 0],
              'onTwigTemplatePaths' => ['onTwigTemplatePaths', 0],
          ];
      }
  }

Configuration

Configuration shall be set in config/plugins/prism-highlight-simpler.yaml.

enabled: true
theme: prism-base16-ocean.dark.css
line-numbers: true  
default-language-toggle: true
default-language-value: txt

You can also override configuration settings at the page level by prefixing options with prism-highlight-simpler:. For example you could set a different theme, and turning on line numbers on a particular page with:

title: My Page
prism-highlight-simpler:
  theme: base16-duotone-dark.light.css
  line-numbers: true 

Themes

The themes available are those of the original plugin (listed in the README).

I've just added my personal theme, using Base2Tone, in different versions; the dark version is the default specified in the config file (prism-base2tone-momh-dark.css).
