Sassify

Adds support for SCSS stylesheets to wp_enqueue_style.

Compile SCSS (Sass) to CSS straight from the WordPress admin. Theme SCSS Compiler manages as many SCSS → CSS file pairs as your theme needs, under Tools → Theme SCSS Compiler. It uses the bundled scssphp library, so there is no Node.js, no build step and no command line. SCSS is the modern Sass syntax: plain CSS plus nesting, variables and <code>@import</code>.
<h4>Features</h4>
<ul>
<li>Multiple file pairs – as many SCSS → CSS pairs as your theme needs, paths relative to the active theme.</li>
<li>Frontend or Admin per pair – each pair enqueues on <code>wp_enqueue_scripts</code> or <code>admin_enqueue_scripts</code>.</li>
<li>Per-file versioning – every pair has its own version, applied through the <code>style_loader_src</code> filter. Your theme files stay untouched.</li>
<li>Smart change detection – a version only bumps when that pair’s compiled CSS really changed.</li>
<li><code>@import</code>-aware recompile – every partial (<code>@import</code>, <code>@use</code>, <code>@forward</code>) is tracked. Edit a partial and the next admin page load recompiles.</li>
<li>Compressed or expanded output – minified for production, readable for development.</li>
<li>Auto-compile – missing or stale CSS is rebuilt on the next admin page load, so a deploy never leaves you with unstyled pages.</li>
<li>Auto-enqueue – the plugin calls <code>wp_enqueue_style()</code> for each pair and skips files already registered, so output is never duplicated.</li>
<li>Manual compile button – one click, live feedback, persistent error display.</li>
<li>Concurrent-compile lock – two admins compiling at once can’t corrupt the CSS.</li>
<li>Code-first config – set every option as a PHP constant in <code>wp-config.php</code>, your theme, or <code>.env</code> / Bedrock.</li>
<li>Admin-only – every endpoint needs <code>manage_options</code>. Change that with the <code>tscsscompiler_capability</code> filter.</li>
<li>Modern and accessible – PHP 8.1+, WCAG 2.1 AA admin UI, German translation included.</li>
</ul>
