<p>CU Debug Tool is a lightweight yet powerful debugging assistant designed for WordPress developers. Built with a modular architecture, it provides a clean, dark-mode overlay that helps you analyze what is happening under the hood of your WordPress site.</p>
<p><strong>Key Features:</strong></p>
<ul>
<li><strong>Dumps:</strong> Tired of cluttering your frontend with <code>var_dump</code> or <code>print_r</code> breaking the layout? Use our helper function <code>cu_dump()</code> to capture variable data cleanly and display it inside the debug panel without affecting your site’s design.</li>
<li><strong>Log Viewer:</strong> Don’t want to log in to your server via FTP just to check errors? View the realtime contents of your <code>debug.log</code> file and clear it instantly directly from the toolbar.</li>
<li><strong>ACF Fields Viewer:</strong> Working with ACF Blocks or Options pages? Stop guessing the array structure. Instantly inspect clean, readable data for current Post Meta, Global Options, and specific Gutenberg Blocks without the internal metadata noise.</li>
<li><strong>Hooks:</strong> Debugging the event-driven architecture? Search for any Action or Filter hook to see a list of all attached callbacks, their priorities, and exactly where they are defined in the code.</li>
<li><strong>Rewrites:</strong> Permalink headaches? Test any URL against your active rewrite rules to see exactly which rule matches, what query variables are parsed, and why you might be getting 404 errors.</li>
<li><strong>Globals:</strong> Wondering which template is rendering the current page? Need to check active PHP variables, memory usage, or <code>wp-config.php</code> constants? This tab gives you a complete snapshot of the current environment.</li>
<li><strong>Inspector:</strong> Your central search engine for WordPress internals. Quickly inspect the raw value of any database Option (<code>get_option</code>) or interactively test specific hooks and rewrites without writing temporary code.</li>
<li><strong>Registry:</strong> A comprehensive manifest of your system. View all scheduled WP-Cron events (including overdue status) and use the “Shortcode Detective” to find the exact file and line number where a shortcode is defined.</li>
<li><strong>Assets:</strong> Wondering what scripts and styles are loading on the current page? Get a quick, organized list of all enqueued CSS and JavaScript files to debug dependencies.</li>
<li><strong>Mails:</strong> Need to verify if WordPress is actually sending emails? Inspect the headers and content of every email sent via <code>wp_mail()</code> during the current request.</li>
<li><strong>SQL Monitor:</strong> Analyze database queries on demand. Toggle recording only when you need it to inspect raw SQL, identify slow queries, and spot duplicates without slowing down your site permanently.</li>
<li><strong>Tools:</strong> A suite of one-click utilities for developers. Flush rewrite rules, clear Transients (cache), and send test emails to verify SMTP configuration instantly.</li>
</ul>
<p><strong>Security & Performance</strong><br />
The tool is only visible to administrators (<code>manage_options</code> capability).</p>

<p>Toggles human and machine language (aka ID-s) on admin pages.</p>
<h4>Only for development!</h4>
<p>This plugin shows you the ID-s of almost all form fields including selects, checkboxes and radio buttons like in <code>wp-admin/options.php</code>.</p>
<p>It works only on WordPress Settings API-like formatted — not necessarily API generated — admin pages. E.g. <code><input></code> elements cannot be wrapped in <code><span></code>.</p>
<h4>Activation</h4>
<p>You can find the plugin’s checkbox in standard Screen Options (upper right corner). This checkbox could be overwritten — thus hidden — by poorly written plugins. To restrict Machine Language to a certain admin page, copy this to your <code>wp-config.php</code>:</p>
<pre><code>define( 'MACHINE_LANGUAGE_HOOK', 'load-options-reading.php' ); </code></pre>
<p>For example this line causes to run only on Settings / Reading.</p>
<h4>Features</h4>
<ul>
<li>Basically all input ID-s are displayed in place of labels, actually <code>for</code> attributes of labels</li>
<li><code>select</code>-s get a title showing all option values comma separated (hover over <code>select</code>-s with your mouse)</li>
<li><code>option</code>-s get values appended in the form of “original option text|value”</li>
<li>Radio button labels will show: “name|value”</li>
<li>Descriptions (<code>p</code>-s and <code>span</code>-s with “description” class) will be hidden, this way Machine Language will clean up all admin pages, descriptions are hidden by CSS, so there’s no <a href="http://en.wikipedia.org/wiki/Flash_of_unstyled_content" rel="nofollow ugc">FOUC</a></li>
</ul>
<h4>Other notes</h4>
<ul>
<li>Radio buttons or checkboxes with empty value are displayed with the “Empty Set” Unicode character: “? ” (U+2205) ( e.g. Settings / Permalinks / Default )</li>
<li><code>select</code>-s with empty values are not</li>
<li>The plugin’s checkbox in Screen Options is effective immediately</li>
<li>The code is designed as a must use plugin, so there is no separated Javascript or CSS file</li>
<li>State of Machine Language is saved as a user option so it is a per user setting</li>
</ul>
