MITS No Lonely Words

No Lonely Words solves a common Polish typography problem: single-letter conjunctions and prepositions (a, i, w, z, o, u…) left alone at the end of a line. The plugin replaces the trailing space after these words with a non-breaking space ( ) so they always stay attached to the following word. How it works Content is processed once when a post is saved and the result is stored in post meta. On every subsequent frontend request the plugin reads directly from WordPress's in-memory meta cache (no regex, no extra database queries). For posts created before activation, inline processing runs on the first view and is cached for the rest of that request. Supported words Polish conjunctions and prepositions: a, i, w, z, o, u, do, ku, na, od, po, we, za, ze, ale, czy, bo, nie, już, też, się, jak, co, to, oraz, lecz, więc, przez, przed, przy, nad, pod, bez, dla, m.in., np., tj. and more.

2.2.0

• the_content filter now skips pages built with Elementor, Beaver Builder, or Divi. These builders replace the_content at priority 12 with their own fully-rendered HTML; running mitsnolo_process on that output corrupted widget markup (carousel, nested sections). The fix has no effect on standard posts/pages.
• Each save now stores the previous version of the cache in _no_lonely_words[prev].
• Added admin metabox (post sidebar) with "Wyczyść cache" and "Przywróć poprzednią" buttons for manual revert.

2.1.0

• Renamed all functions and constants to use the mitsnolo_ prefix (4+ characters).
• Added wp_kses_post() escaping to content/excerpt filter callbacks.
• Added wp_kses() escaping with inline-tag allowlist to title/heading filter callbacks.

2.0.0

• Rewrite: process on save_post, store result in postmeta. Zero regex on frontend requests.
• Static in-request cache layer for repeated filter calls within a single page load.
• Fallback inline processing for posts without cached meta (e.g. created before activation).
• the_title filter now correctly receives the post ID as the second argument.

1.0.0

• Initial release.
