The CC-Syntax-Highlight plugin supports syntax highlighting of Posts, Pages, and any public Custom Post Types. 
It uses <a href="https://highlightjs.org/" rel="nofollow ugc">highlight.js</a> or <a href="https://github.com/google/code-prettify" rel="nofollow ugc">google-code-prettify</a> libraries. 
Additionally it can use the <a href="https://clipboardjs.com/" rel="nofollow ugc">clipboard.js</a> library to add a button that copies text to the clipboard and <a href="https://github.com/wcoder/highlightjs-line-numbers.js/" rel="nofollow ugc">highlightjs-line-numbers.js</a> plugin to add line numbers. 
It is delivered with support for shortcode (default [code] – you can change it on the settings page) which automatically converts all special characters to HTML entities. 
This plugin is compatible with Multisite WordPress installations.
<h4>How does it work?</h4>
<ol>
<li>Go to the ‘Settings > Syntax Highlight’ page, select your preferred options and save them.</li>
<li>Simply add the source code to your post (or other selected public Custom Post Type) wrapped with: 
<pre><code>Your source code</code></pre> 
or if you would like to automatically convert all special characters to HTML entities, use shortcode wrapper instead (default [code] – you can change it on the settings page): 
<pre>[code]Your source code[/code]</pre></li>
</ol>
Plugin’s js scripts and css styles files only load if the source code occurs on displaying page.
