A syntax highlighter using PrismJs.
<h3>How To Use</h3>
Wrap your pre tag as shown below:
<pre>
[sh_prismjs_pre class="language-py line-numbers match-braces rainbow-braces" data_line="1,4-5,7" escape_html='escape']
<pre> 
class Implements_Ne:
 ''' A class which implements 
 the __ne__ method '''
 def __ne__( self, other):
 return False

class Not_Implements_Ne:
 ''' A class which does not
 implement the __ne__
 method '''
 pass
</pre>
[/sh_prismjs_pre]
</pre>
<ul>
<li>Replace name in language-NAME, by the name of the language that you wish to highlight. For example if the language is python, language-NAME should become language-py .</li>
<li>If you wish line numbers to appear, use line-numbers . </li>
<li>If you wish braces to be matched when selected use match-braces . </li>
<li>If you wish to have rainbow braces use rainbow-braces . </li>
<li>If you wish to highlight lines, you can use data_line, so in the example provided, colorize line 1, and colorize lines from 4 to 5, and colorize line 7. </li>
<li>If you wish the content of the pre to be escaped, so for example if it contains html tags that you do not wish to be rendered, you can use escape_html=’escape’</li>
</ul>
For code tags, they also should be wrapped as follows:
<pre>
[sh_prismjs_code class="language-html" escape_html='escape']<code>tag: </code>[/sh_prismjs_code]
</pre>
You must use the language-Name option, and you can use the escape_html option.

Syntax Highlighter with PrismJS

Coywolf Code Block Enhancer extends the built-in <code>core/code</code> block. In the editor 
it adds a “Code language” dropdown to the block sidebar; on the front end 
it highlights the code with Prism.js using a custom token palette, prints 
the language name as a small label on the block, and pins a 
copy-to-clipboard button to the top-right corner.
<ul>
<li>Adds a “Code language” dropdown to the core Code block’s sidebar. A 
baseline of 9 languages (Bash, CSS, HTML/Markup, JavaScript, JSON, 
PHP, Python, SQL, YAML) is always loaded; an additional 40 grammars 
can be toggled on via Language packs in Tools → Code Blocks 
(Web/App dev — TypeScript, JSX/TSX, SCSS, Sass, Less, GraphQL — is 
enabled by default).</li>
<li>Highlights code on the front end with Prism.js. Pick from 45 bundled 
themes — the 8 stock Prism themes (Prism Default, Coy, Dark, Funky, 
Okaidia, Solarized Light, Tomorrow Night, Twilight) plus 37 community 
themes from PrismJS/prism-themes (a11y Dark, Atom Dark, Dracula, 
Nord, One Dark, Night Owl, Synthwave ’84, Gruvbox, Material, VS Code 
Dark+, and more) — or the bundled Default palette (selected on 
first install).</li>
<li>Adds a small language label in the top-left of each highlighted block 
(only when a language is set).</li>
<li>Adds an accessible copy-to-clipboard button — <code>aria-label</code>, a polite 
status region that announces “Copied to clipboard,” and a visible “✓” 
state for two seconds after a successful copy. Falls back to 
 document.execCommand(‘copy’) on non-HTTPS or older browsers.</li>
<li>Assets load only on singular posts/pages that contain a code block; 
Prism core and grammars are loaded with the <code>defer</code> strategy so they 
never block rendering.</li>
<li>Dark-mode aware out of the box — with the bundled Default — Auto 
theme (selected on first install), code blocks follow each visitor’s 
 prefers-color-scheme automatically. Override from 
Tools → Code Blocks by switching to Default — Always light / 
Always dark, or by picking any of the static Prism themes.</li>
</ul>
<h4>How it works</h4>
The chosen language is stored as a <code>language</code> block attribute on 
 core/code, which lives in the block delimiter comment rather than the 
saved markup. That means blocks without a language stay valid and 
existing content is never migrated.
On render, the plugin uses <code>WP_HTML_Tag_Processor</code> to add <code>data-language</code> 
to the <code><pre></code> and <code>language-xxx</code> to the <code><code></code> server-side — so KSES 
won’t strip <code>data-*</code> attributes for non-admin authors, and there is no 
block-validation churn.
Prism core and the per-language grammars are bundled under 
 assets/prism/ at v1.30.0 (MIT — see <code>assets/prism/LICENSE.txt</code>). They 
register as deferred scripts with explicit dependency ordering (e.g. 
 markup-templating before <code>php</code>, <code>clike</code> before languages that extend 
it). The copy-button script depends on the last grammar in the chain, 
so all of Prism is present before the copy UI is wired up. Reading 
 code.textContent returns the original source even after Prism wraps 
tokens in spans, so the copied text is unaffected by highlighting.
Self-hosting Prism (rather than loading from a public CDN) keeps the 
third-party-script supply chain off the plugin’s surface and means the 
plugin works on sites with strict CSPs or no external egress.
<h3>Privacy</h3>
Privacy-first: this plugin includes no analytics, no tracking, and no data gathering. Nothing about you, your site, or your visitors is ever collected or sent anywhere.
