Oriole One Instant Copy enhances the standard WordPress Gutenberg Code block (<code>core/code</code>) by injecting a small, accessible “Copy” button into the top-right corner of every code block on your site — automatically, on every existing and future post.
No shortcodes. No block-editor changes. No database modifications. Pure progressive enhancement.
<h4>How it works</h4>
The plugin uses vanilla JavaScript to detect every <code>pre.wp-block-code</code> element after the page loads and appends a lightweight Copy button. When clicked, the button copies the code text to the system clipboard using the modern <code>navigator.clipboard</code> API, with a <code>document.execCommand</code> fallback for older browsers.
The stored post content is never touched. If you deactivate or uninstall the plugin, your posts are exactly as they were before.
<h4>Key Features</h4>
<ul>
<li>Automatic — works on all existing and future posts without any editor involvement.</li>
<li>Lightweight — total asset footprint under 5 KB combined (CSS + JS). Zero dependencies.</li>
<li>Accessible — keyboard navigable, <code>aria-label</code> support, <code>focus-visible</code> outlines, screen-reader text, reduced-motion aware, high-contrast mode support.</li>
<li>Smart enqueueing — assets are loaded only on pages that actually contain a Gutenberg code block, not on every page of your site.</li>
<li>Clipboard API with fallback — uses <code>navigator.clipboard.writeText()</code> on secure contexts and falls back to <code>execCommand('copy')</code> for legacy environments.</li>
<li>Duplicate-proof — skips any code block that already has a copy button to avoid conflicts with other plugins.</li>
<li>Theme-safe — uses <code>currentColor</code> and semi-transparent backgrounds; works with light and dark themes without hardcoding colours.</li>
<li>No jQuery — vanilla JavaScript only.</li>
<li>No tracking, no telemetry, no external requests — 100% self-hosted.</li>
<li>Multisite compatible.</li>
</ul>
<h4>Settings</h4>
Find the settings under Settings → Oriole One Instant Copy:
<ul>
<li>Enable / Disable the button globally.</li>
<li>Button text — customise the label shown on the button (default: “Copy”).</li>
<li>Success text — customise the label shown after copying (default: “Copied!”).</li>
<li>Position — Top Right (additional positions planned for v2).</li>
</ul>
<h4>Developer Notes</h4>
All settings use the WordPress Settings API with <code>sanitize_callback</code> and proper nonce handling via <code>settings_fields()</code>. No custom REST endpoints, no Gutenberg/React dependencies, no build tools required.
The plugin defines the following PHP constant and classes:
<ul>
<li><code>ORIOLE_OIC_VERSION</code> — current plugin version string.</li>
<li><code>Oriole_OIC_Plugin</code> — main bootstrap class (singleton).</li>
<li><code>Oriole_OIC_Settings</code> — settings page and storage class.</li>
</ul>
Option stored in <code>wp_options</code>: <code>oriole_oic_settings</code> (autoloaded, single serialised array).

LumiCode is a premium-quality syntax highlighter built for developers and technical bloggers who want beautiful, readable code on their WordPress site – without fighting the editor. Learn more and view the live demo at https://cr8vstacks.com/dev-playground/lumicode-syntax-highlighter/
<h3>Key Features</h3>
<ul>
<li>40+ languages auto-detected – PHP, JavaScript, TypeScript, Python, Go, Rust, SQL, YAML, Bash, and more</li>
<li>13 bundled themes – Atom One, Dracula, GitHub, Monokai, Night Owl, Nord, Solarized, VS 2015, Xcode, and more, powered by highlight.js 11.11.1</li>
<li>Dark & Light mode – toggle from the admin topbar. Applies to both admin UI and frontend code boxes</li>
<li>Copy to Clipboard – one-click copy button on every code block</li>
<li>Line numbers – perfectly aligned, synced to font size and line height</li>
<li>Collapse / Expand – long code blocks auto-collapse after a configurable number of lines</li>
<li>Filename / language badge – shows in the titlebar of every code box</li>
<li>TinyMCE integration – Insert Code Block button in the Classic Editor toolbar, with language detection and all options</li>
<li>Gutenberg block – native block editor support</li>
<li>Code Scanner – scans your entire site for bare <code><pre></code> blocks and lets you apply LumiCode with one click, or dismiss</li>
<li>Auto-detect – wraps any existing <code><pre></code> blocks automatically on the frontend without touching your content</li>
</ul>
<h3>How It Works</h3>
LumiCode renders code blocks server-side (shortcodes + TinyMCE insertion) and enhances them on the frontend with a lightweight JS renderer. The renderer wraps <code><pre class="lumicode-pre"></code> elements in a beautiful VS Code-style chrome (titlebar, statusbar, line numbers, copy button) and runs highlight.js for syntax coloring.
No page builders required. Works with any theme.
<h3>Shortcode Usage</h3>
<pre><code>[lumicode lang="javascript"]
const greeting = "Hello, world!";
console.log(greeting);
[/lumicode]
</code></pre>
All shortcode attributes: 
* <code>lang</code> – language identifier (e.g. <code>php</code>, <code>python</code>, <code>typescript</code>) 
* <code>title</code> – filename shown in titlebar (e.g. <code>config.js</code>) 
* <code>highlight</code> – lines to accent (e.g. <code>1,3-5</code>) 
* <code>collapse</code> – force collapse (<code>true</code>/<code>false</code>) 
* <code>collapse-after</code> – collapse after N lines (overrides global setting)
<h3>Performance</h3>
<ul>
<li>highlight.js is loaded locally (v11.11.1) for speed and privacy</li>
<li>Our CSS and JS are tiny (<15 KB combined, unminified)</li>
<li>No jQuery dependency on the frontend</li>
</ul>
