Theme SCSS Compiler

Theme SCSS Compiler lets you manage multiple SCSS → CSS pairs in the active theme directly from the WordPress admin (Tools → Theme SCSS Compiler). It uses the bundled scssphp library — no Node.js, no build tools, no command line. SCSS is the modern Sass syntax (CSS-superset with braces and semicolons).

Features

• Multiple file pairs – configure as many SCSS → CSS pairs as your theme needs (paths relative to the active theme).
• Per-pair Context – each pair runs on either the Frontend (wp_enqueue_scripts) or the Admin (admin_enqueue_scripts).
• Per-file versioning – each pair has its own version. Bumps are applied automatically via the style_loader_src filter, so your theme files stay untouched.
• Smart change detection – the version only bumps when the compiled CSS content of that specific pair actually changed. No cache busting for files you didn’t touch.
• @import-aware auto-recompile – every SCSS partial (@import, @use, @forward) is tracked. Editing a partial alone triggers a recompile on the next admin page load — no need to touch the entry SCSS file.
• Compressed (production) or expanded (development) SCSS output.
• Auto-compile when an SCSS source (or any of its imports) changes or the CSS output is missing – no white layouts after a fresh deployment.
• Auto-enqueue – the plugin runs wp_enqueue_style() for every configured pair on its respective context. Skips files that are already registered, so it never duplicates output.
• Manual compile button with live AJAX feedback and persistent error display in the admin.
• Concurrent-compile lock – a transient-based mutex prevents two admins triggering compiles at the same time from corrupting the CSS output.
• Code-first configuration – every option (pairs, output style, auto-compile, auto-enqueue, bump version) can be defined as a PHP constant in wp-config.php, in your theme, or via your .env / Bedrock workflow.
• Admin-only access – every endpoint requires the manage_options capability by default. Filterable via tscsscompiler_capability if you need to grant access to a custom role.
• Modern codebase – PHP 8.1+, WCAG 2.1 AA compliant admin UI, fully translated to German out of the box.
