From the developer
Karolina Vyskocilova's own description of Zalomení, lightly tidied.
Zalomení is a WordPress plugin that automatically applies Czech typographic rules to post content, titles, comments, and widgets. It replaces ordinary spaces with non-breaking spaces wherever Czech typography forbids a line break, so editors don’t have to type them by hand.
Although Czech is the default, the plugin is structured around editable lists of prepositions, conjunctions, and abbreviations — so it can be adapted to Slovak (and other closely related languages) simply by adjusting those lists in the settings.
Maintainer
Zalomení is maintained by Karolína Vyskočilová, an independent WordPress developer based in Czechia, who took the plugin over in 2026 and ran a full security audit. The plugin was originally created by Honza Skýpala, whose work is gratefully acknowledged.
What the plugin handles
- Prepositions — single-letter prepositions like k, s, v, z must not appear at the end of a line.
- Conjunctions — single-letter conjunctions like a, i, o, u.
- Abbreviations — common Czech abbreviations (e.g. např., tj., tzv.).
- Numbers and units — prevents breaks between a number and its unit (e.g. 5 kg, 10 Kč).
- Number formatting — keeps formatted numbers together (e.g. phone numbers like 800 123 456).
- Ordinal numbers — prevents breaks after ordinals, especially in dates (e.g. 1. ledna).
- Scales and ratios — keeps expressions like 1 : 50 000 on one line.
- Custom terms — user-defined multi-word terms that should never be broken across lines.
All options are configurable under Settings → Reading. The plugin exposes a zalomeni_filtry filter so developers can add or remove the WordPress hooks Zalomení applies to.
