<h3>Customization</h3>
<p>Syntax coloring is highly customizable: you could change the  color scheme for all languages or a specific language. You could find CodeColorer CSS in <strong>wp-content/plugins/codecolorer/codecolorer.css</strong> file. To change colors for all languages edit lines below <em>Color scheme</em> section.</p>
<p>There is a simple mapping between TextMate color themes and CodeColorer ones:</p>
<pre><code>/* "Slush & Poppies" color scheme (default) */
.codecolorer-container, .codecolorer { color: #000000; background-color: #F1F1F1; }
/* Comment */
.codecolorer .co0, .codecolorer .co1, .codecolorer .co2, .codecolorer .co3, .codecolorer .co4, .codecolorer .coMULTI { color: #406040; font-style: italic; }
/* Constant */
.codecolorer .nu0, .codecolorer .re3 { color: #0080A0; }
/* String */
.codecolorer .st0, .codecolorer .st_h, .codecolorer .es0, .codecolorer .es1 { color: #C03030; }
/* Entity */
.codecolorer .me1, .codecolorer .me2 { color: #0080FF; }
/* Keyword */
.codecolorer .kw1, .codecolorer .kw2, .codecolorer .sy1 { color: #2060A0; }
/* Storage */
.codecolorer .kw3, .codecolorer .kw4, .codecolorer .kw5, .codecolorer .re2 { color: #008080; }
/* Variable */
.codecolorer .re0, .codecolorer .re1 { color: #A08000; }
/* Global color */
.codecolorer .br0, .codecolorer .sy0 { color: #000000; }

Code Prettify

I tried to use this plugin in WP 5.0.2 and it works. I got an issue with Litespeed cache configuration and seems we should exclude this plugin javascript from an optimization process. Then you will be fine!

It works as expected!

Perfect. Automatic.

Finally a plugin that works with the outdated "Crayon Syntax Highlighter" plugin

So I don't have to mess around with every post.

Good replacement

Your plugin makes me very secure and happy to use because it doesn't make me dependent, I can disable it without affecting the articles. Good job.

I just hope you can keep the plugin up to date to be compatible with new versions of WordPress.

Thank you!

Please keep update to compatible with WordPress version

100% automatic code highlighting using the Prettify library. No shortcodes, no classnames, fully automatic and pure awesome.
